RESUMEN

Psychological entitlement has appeared as a significant topic for research in the field of management and Psychology. From the perspective of social comparison theory, the present study aimed to investigate the impact of psychological entitlement on engagement in learning activities and psychological anxiety in the hotel industry. Furthermore, benign and malign envy were examined as an explanatory mechanism between psychological entitlement and its outcomes. Based on a three-wave time-lagged design, data were obtained from 242 employees working in the different hotels in Pakistan. We found that psychological entitlement's has no direct influence on hotel employees engagement in learning activities, and psychological anxiety. In addition, the indirect effect of psychological entitlement on both outcomes (engagement in learning activities and psychological anxiety) was found significant through the mediating effect of benign and malign envy. The implications for research theory and practice are discussed.

RESUMEN

OBJECTIVE: Envy and interpersonal curiosity are common emotional and psychological phenomena in relationships that collectively influence our social behavior and experiences. However, there is a research gap regarding the interaction between interpersonal curiosity and envy. Therefore, this study will primarily utilize daily diary methods to investigate the relationship between interpersonal curiosity and envy. METHOD: Using the Benign and Malicious Envy Scale and the Chinese Adolescents' Interpersonal Curiosity Questionnaire, Study 1 conducted a preliminary study on 392 middle school students using cross-sectional data. Based on the data from Study 1, we selected the ten items (2 items per variable) with the highest factor load for the daily measurement of Study 2. Study 2 utilized the diary method and recruited 81 adolescents as participants for a 14-day measurement period. RESULTS: The results of Study 1indicate a significant correlation between malicious envy and interpersonal curiosity, as well as a significant correlation between benign envy and interpersonal curiosity (excluding general interpersonal curiosity). The findings from Study 2 indicate that daily malicious envy can enhance private interpersonal curiosity and general interpersonal curiosity, daily benign envy can enhance curiosity exploration, and daily curiosity exploration can also enhance benign envy. DISCUSSION: This study enhances comprehension of the two-way relationship between adolescent envy and interpersonal curiosity within the framework of social comparison theory. The findings underscore the significance of adolescents recognizing and respecting others' boundaries to mitigate the adverse effects linked to malicious envy. Furthermore, adolescents are encouraged to channel benign envy into a source of motivation, fostering personal growth and fostering positive relationships through curiosity exploration.

RESUMEN

BACKGROUND: The Benign and Malicious Envy Scale (BeMaS) is designed to assess the trait of envy and evaluate individual differences in people's tendency to experience benign or malicious envy towards superior comparison standards. OBJECTIVE: This study aimed to examine the factor structure of the BeMaS in Arab culture through exploratory and confirmatory factor analysis and to ensure the measurement equivalence of the benign and malicious envy scale across three countries in the Arab Maghreb region (Algeria, Tunisia, and Morocco). METHODS: The study was conducted on a sample of 1047 students from various universities across three countries, Algeria (n = 401), Tunisia (n = 289), and Morocco (n = 357), and implemented a cross-sectional study design. The study involved individuals aged 18-64 (M = 22.00, SD = 4.79). Most were females (64.4 %, n = 674), with substantial male representation (35.6 %, n = 373). All participants completed the Arabic BeMaS. RESULTS: The confirmatory factor analysis results indicated that the Arabic BeMaS has a two-factor structure for the total sample and each subsample. However, some modifications were necessary in the Tunisian sample. The overall results suggest that the two-factor structure of the BeMaS is valid and reliable in the Arab context. At the same time, differences between the three groups suggest cultural differences despite similarities in language, geographic proximity, and shared customs and traditions. Additionally, the results highlight the need for further research into envy, particularly within Arabic culture. Religious and cultural traditions may significantly influence how envy is experienced and perceived, making such cultural differences important to investigate. CONCLUSION: In summary, this study contributes to our measurement of Envy in the Arab context by validating BeMaS and highlighting the importance of cultural factors in measuring and explaining envy. However, further research is needed to deepen our understanding of this complex emotion in different cultural and social contexts.

RESUMEN

Previous studies have examined the impact of maternal childhood maltreatment (CM) on children's school adaptation (SA), neglecting the role of fathers, and the joint influence of both parents. Based on family systems theory, this study explored the intergenerational impact of parental CM on children's SA and the mediating role of benign envy (BE) and malicious envy (ME). A total of 334 elementary school students' BE, ME, and SA statuses and their parents' CM, BE, and ME statuses were collected to construct the intergenerational transmission models of BE and ME for fathers, mothers, and parents, respectively. The results revealed that maltreated fathers or mothers individually exerted negative impacts on their children's SA, but when parents acted jointly, only fathers' CM intergenerational influence was significant. Mediation effects demonstrated that, individually, maltreated fathers indirectly affected children's SA through children's BE; maltreated mothers impacted children's SA through the "mothers' BE→children's BE" mediating chain; however, when taking combined parental action, only mothers' intergenerational transmission chain was significantly present. Identifying different intergenerational influence mechanisms of maltreated parents on offspring's school adaptation broadens our understanding of the diverse parenting roles of parents. That is, fathers foster their offspring's environmental adaptability through encouraging external exploration, while mothers enhance socialization by nurturing internal emotional development. Formulating strategies to address the emotional issues of maltreated parents, especially mothers, is crucial for mitigating the intergenerational consequences of maltreatment and enhancing the offspring's adaptability.

RESUMEN

INTRODUCTION: Subjective well-being, an important index for measuring mental health, is presently declining among junior high school students. Envy, one of their common emotions, is inextricably linked to subjective well-being. Based on the Dual Envy Theory, our research explores the bidirectional relationship between benign-malicious envy and subjective well-being. The mediating role of self-esteem, as well as the related gender differences, is examined. METHODS: Chinese middle school students (n = 1566, boys 50.3%, age = 13.96 ± 0.88 years old) were assessed at two time points over a 3-month interval. Structural equation modeling was used to examine the longitudinal relationships among the variables. RESULTS: (1) Cross-lagged analysis showed a positive bidirectional relationship between benign envy and subjective well-being and a negative bidirectional relationship between malicious envy and subjective well-being in the total sample. However, the path from T1 subjective well-being to T2 malicious envy in boys was not significant. (2) Self-esteem mediated the relationship between both benign and malicious envy and subjective well-being among both boys and girls. A Wald chi-square test showed that T2 self-esteem was a stronger predictor of T2 benign envy in boys than in girls. CONCLUSION: The results reveal a virtuous cycle of benign envy and subjective well-being, and a vicious cycle of malicious envy and subjective well-being, while emphasizing the role of self-esteem in this process. Gender differences were also noted. These findings have important implications for improving the subjective well-being of secondary school students and exploring the positive effects of envy.

RESUMEN

Background: With increasing gaps between the rich and poor, potential risk factors for class conflict have attracted increasing attention from researchers. Although cognitive factors are known to be significant predictors of class-conflict behavior, limited attention has been paid to competence stereotypes of the upper class. When considering economic inequality, people pay more attention to competence stereotypes of the upper class, which may have adverse effects. This study aimed to investigate the relationship between competence stereotypes held by the lower class about the upper class and class conflict, and to test the mediating role of intergroup envy in this relationship and the moderating role of upward social mobility belief. Methods: Data were collected from a convenience sample from a comprehensive university in China. Based on scores on subjective and objective class scales, 284 lower-class college students (103 males and 181 females) aged 18-24 were selected to participate (both their subjective and objective scores were lower than 3 points). Their endorsement of upper-class competence stereotypes, intergroup envy, upward social mobility beliefs, and class conflict were measured using a well-validated self-report questionnaire. Results: The main data were analyzed using correlation analysis, the SPSS macro PROCESS (Model 7), and simple slope analysis. The results show a significant positive correlation between competence stereotypes held by lower-class college students toward the higher class and class conflict, and this connection was mediated by intergroup envy. Moreover, the indirect effect of intergroup envy on this link was moderated by upward social mobility beliefs; this effect was stronger for college students with lower upward social mobility beliefs. Conclusion: This study broadens our understanding of how and when competence stereotypes among the lower class concerning the upper class are related to class conflict. Researchers and policymakers should pay special attention to competence stereotypes of the upper class, especially intergroup envy and class conflict among lower-class individuals with lower levels of upward social mobility beliefs.

RESUMEN

Previous studies have a lack of meta-analytic studies comparing the trait (personality) envy, social comparison envy, and love-envy, and the understanding of the similarities and differences in the neural mechanisms behind them is relatively unclear. A meta-analysis of activation likelihood estimates was conducted using 13 functional magnetic resonance imaging studies. Studies first used single meta-analyses to identify brain activation areas for the three envy types. Further, joint and comparative analyses were followed to assess the common and unique neural activities among the three envy types. A single meta-analysis showed that the critical brain regions activated by trait (personality) envy included the inferior frontal gyrus, cingulate gyrus, middle frontal gyrus, lentiform nucleus and so on. The critical brain regions activated by social comparison envy included the middle frontal gyrus, inferior frontal gyrus, medial frontal gyrus, precuneus and so on. The critical brain regions activated by love-envy included the inferior frontal gyrus, superior frontal gyrus, cingulate gyrus, insula and so on. In terms of the mechanisms that generate the three types of envy, each of them is unique when it comes to the perception of stimuli in a context; in terms of the emotion regulation mechanisms of envy, the three types of envy share very similar neural mechanisms. Both their generation and regulation mechanisms are largely consistent with the cognitive control model of emotion regulation. The results of the joint analysis showed that the brain areas co-activated by trait (personality) envy and social comparison envy were frontal sub-Gyral, inferior parietal lobule, inferior frontal gyrus, precuneus and so on; the brain areas co-activated by trait (personality) envy and love-envy were extra-nuclear lobule, lentiform nucleus, paracentral lobule, cingulate gyrus and so on; the brain regions that are co-activated by social comparison envy and love-envy are anterior cingulate gyrus, insula, supramarginal gyrus, inferior frontal gyrus and so on. The results of the comparative analysis showed no activation clusters in the comparisons of the three types of envy.

RESUMEN

Our proposition postulates that the correlation between the wrongdoer's status and the punishment suggestions of onlookers is primarily influenced by group-oriented envy rather than the ascription of intentionality and is moderated by the belief in a just world. In three separate studies, 389 university students were asked to read scenarios describing a hit-and-run crime committed by either a rich or a poor individual and then report their opinions on intentionality attribution (Study 1 and Study 2), envy emotions (Study 2), punishment recommendations (all three studies), and belief in a just world (Study 3). Consistently, the findings indicated that those observing recommended harsher penalties to be imposed upon high-status perpetrators engaging in the same wrongdoing (such as hit-and-run) as their low-status equivalents. The effect of the rich receiving more severe punishment was predicted more strongly by envious emotions than by intentionality attributions to high-status wrongdoers and was only present for those observers who endorsed a lower belief in a just world.

RESUMEN

The Covid-19 pandemic revealed the difficulties of vaccinating a population under the circumstances marked by urgency and limited availability of doses while balancing benefits associated with distinct guidelines satisfying specific ethical criteria. We offer a vaccination strategy that may be useful in this regard. It relies on the mathematical concept of envy-freeness. We consider finding balance by allocating the resource among individuals that seem heterogeneous concerning the direct and indirect benefits of vaccination, depending on age. The proposed strategy adapts a constructive approach in the literature based on Sperner's Lemma to point out an approximate division of doses guaranteeing that both benefits are optimized each time a batch becomes available. Applications using data about population age distributions from diverse countries suggest that, among other features, this strategy maintains the desired balance, throughout the entire vaccination period. We discuss complementary aspects of the method in the context of epidemiological models of age-stratified Susceptible - Infected - Recovered (SIR) type.

RESUMEN

This study investigates the relationship between labor values and two forms of envy-benign and malicious-as well as the potential mediating role of mindfulness using a mindfulness reperceiving model. Two thousand three hundred sixty three Chinese teenagers participated in a longitudinal study over an eight-month period, completing questionnaires measuring labor values, benign envy, malicious envy, and mindfulness. The cross-sectional data showed that labor values had an immediate negative effect on malicious envy, with mindfulness partially mediating this relationship. Additionally, labor values had an immediate positive effect on benign envy, but mindfulness did not mediate this relationship. Longitudinal data analysis revealed that the delayed effect of labor values on later benign/malicious envy was similar to its immediate effect. However, mindfulness only played a mediating role in the relationship between labor values and later malicious envy. Cross-gender stability was found in both the immediate effect model and the delayed effect model. Overall, this study sheds light on the influence of labor values on the development of social emotions and the potential mediating role of mindfulness in the Chinese cultural context.

RESUMEN

Models of radicalization have typically placed grievances at the heart of radicalization. In contrast, we argue that viewing the radicalizing agent as decidedly proactive, and less reactive, better accounts for the available data. At the core of our radicalization model is the functional structure of envy. The operative properties of the emotion align with essential and conspicuous features of the radicalization process: a motivation to monitor social differentials, an identification of sources of postulated welfare costs, an impulse to eliminate or depower purported competitors, an attempt to diffuse responsibility for one's aggressive actions, and the rejoicing at the envied agent's misfortune. Two of those operative properties are particularly important for our understanding of radicalization. Envy motivates the neutralization of competitors when responsibility for welfare costs is not objectively attributable to others' wrongdoing toward the party who feels injured. The "process of typification" serves as a means to diffuse responsibility. It extends the reach of individual concerns by downplaying the particulars of the personal situation motivating the envious agent while evoking universally shared interaction templates (e.g., humiliation, injustice) to appeal to a broader audience.

RESUMEN

BACKGROUND: Social media benign envy, an upward comparison-based and painful emotions associated with the motivation to improve oneself, has attracted increasing attention from researchers due to its ubiquitous and significant impact on social network users' intentions and behavior. However, the results of previous studies on whether material or experiential consumption is more likely to cause social media envy (treated as a single construct) have been inconsistent, and there is a lack of research on what triggers social media users to experience more intense benign envy and thus inspiring their consumption intentions. The purpose of this study is to investigate how the type and luxuriousness of shared consumption and viewer's social comparison orientation jointly affect social media users' consumption intentions through benign envy. METHODS: A 2 (type of consumption sharing: experiential vs. material) × 2 (luxuriousness of consumption sharing: luxury vs. non-luxury) × 2 (social comparison orientation: high vs. low) mixed-design experiment was conducted to test theoretical model with data from 544 undergraduates in China. SPSS 26.0 and the Process macro were used to test the model. RESULTS: The results revealed that luxury experiential consumption information shared on social media triggered more benign envy compared with other types of shared consumption information. When social media users shared non-luxury consumption, experiential consumption was more likely to inspire benign envy among users with high social comparison orientation than material consumption. However, when luxury consumption was shared, benign envy acted as a mediator between purchase type and participants' purchase intention regardless of whether participants' social comparison orientation was high or low. CONCLUSION: This study revealed that whether and how social comparison orientation of social media users who read the shared content influences the mechanism by which the type of consumption sharing on social media affects social media users' consumption intentions through benign envy as a mediator is dependent on the luxuriousness of the shared consumption. The findings not only provide new insights for researchers to better understand social media envy and the underlying psychological mechanism for social media readers' consumption intention, but also have practical implications for practitioners.

RESUMEN

When working alongside proactive colleagues, do you elevate yourself through benign envy or resort to malicious envy? To address this intriguing question, we constructed a model based on social comparison theory to measure the double-edged sword effects of proactive personality on employee outcomes. We hypothesized that proactive employees would induce two distinct tendencies in their peers-workplace ostracism and employee creativity-due to peer envy. The study analyzed 389 valid responses from full-time employees in Chinese organizations using structural equation modeling. Results indicate that proactive personality positively influences benign envy among peers, which in turn positively affects employee creativity. Moreover, benign envy mediates the relationship between proactive personality and employee creativity. On the other hand, proactive personality positively influences malicious envy among peers, which in turn positively affects workplace ostracism. Additionally, malicious envy mediates the relationship between proactive personality and workplace ostracism. This study intertwines personality, emotions, and workplace outcomes, thereby advancing the existing literature on social comparison theory. Additionally, it furnishes valuable insights for organizational human resource management, particularly in the realms of employee recruitment and workplace relationship management.

RESUMEN

AIM: To determine whether nurses' self-efficacy affected envy levels and to develop the necessary strategies. BACKGROUND: Envy is a widespread global phenomenon. Envy can harm the individual, the work environment, and nursing care. However, the relationships between self-efficacy and envy have not been adequately explored in the nursing context. METHODS: This study was conducted as a cross-sectional descriptive study. The study sample consisted of 361 nurses working in a university hospital in a province of Türkiye. The research model was analyzed using structural equation modeling. The participants were selected using convenience sampling. This study was reported using the STROBE checklist for cross-sectional studies. RESULTS: Nurses' educational status affected their self-efficacy. No other personal characteristics influenced self-efficacy and envy. There was a positive relationship between malicious and benign envy. As nurses' self-efficacy increased, malicious envy decreased and benign envy increased. CONCLUSIONS: The results of this study showed that nurses' education level affected self-efficacy, and self-efficacy level affected envy, and malicious envy could be reduced by improving nurses' self-efficacy. IMPLICATIONS FOR NURSING AND HEALTH POLICY: Nursing managers and policymakers should support nursing education at the minimum undergraduate level, encourage nurses to continue their professional education to improve their self-efficacy, and provide training to increase their self-efficacy.

RESUMEN

Although previous cross-sectional studies have investigated the between-person correlation between dispositional envy and subjective well-being, few longitudinal studies have explored the within-person relationships between state benign/malicious envy and subjective well-being, as well as the intrapersonal and interpersonal mechanisms involved. This study adopted a diary approach for 14 consecutive days from a sample of 167 young women to investigate the within-person associations among benign/malicious envy, self-esteem, perceived social support, and subjective well-being. The results revealed that benign and malicious envy had opposite effects on subjective well-being within individuals. Besides, the results indicated that self-esteem and perceived social support mediated the relationships between benign envy and two dimensions of subjective well-being (positive affect and life satisfaction) within individuals. Furthermore, self-esteem played a within-person mediating role in the relationships between malicious envy and three dimensions of subjective well-being, whereas perceived social support only served as a within-person mediator between malicious envy and positive affect. These findings shed light on the distinction between benign envy and malicious envy and help in comprehending the intrapersonal and interpersonal mechanisms through which the two types of envy impact subjective well-being in daily life.

RESUMEN

Using a prototype approach to emotion concepts, we mapped the internal structure and content of the everyday concept of envy (as used in the United States) and its translation equivalents of envidia in Spanish and Neid in German. In Study 1 (total N = 415), the features of the concept of envy, envidia, and Neid were generated via an open-ended questionnaire. In Study 2 (total N = 404), participants rated the degree of typicality of the constitutive features on a forced-choice questionnaire. The prototype analysis of envy, supplemented with network analyses, revealed that the largest connected set of features of envy, envidia, and Neid shared a group of central features, including features related to success or to people with a better appearance. Still, envy, envidia, and Neid did differ with respect to their constituent peripheral features as well as the density of their networks, their structure, and the betweenness centrality of the nodes. These results suggest that a prototype approach combined with network analysis is a convenient approach for studying the internal structure of everyday emotion concepts and the degree of overlap with respect to the translation equivalents in different countries.

RESUMEN

Este artigo pretende discutir o texto seminal de Melanie Klein, Inveja e gratidão (1957), no intuito de articulá-lo com os fenômenos da esperança, desesperança, criatividade e destrutividade. Na leitura realizada, observamos que a inveja é um solo fértil para o crescimento da desesperança e destrutividade. Enquanto a capacidade de ter gratidão pode levar o indivíduo a ser esperançoso e ter uma vida criativa, o contrário seria possível? Ser invejoso e ao mesmo tempo ter criatividade e esperança? Com base no dualismo pulsional freudiano, do qual Klein não abriu mão na construção da sua metapsicologia, respondemos que sim, primordialmente a partir da introjeção do objeto bom, que possibilita a elaboração da inveja, elemento que enfatizaremos a partir da figura do analista no processo clínico. Para elucidarmos cada um desses elementos, iremos utilizar o conto "A legião estrangeira" de Clarice Lispector (1999) como fio condutor ao longo de todo o texto.

Resumos This article aims to discuss Melanie Klein's seminal text, "Envy and gratitude" (1957), in order to articulate it with the phenomena of hope, hopelessness, creativity, and destructiveness. In ours readings, we observed that envy is a fertile soil for the growth of hopelessness and destructiveness. While the ability to have gratitude can lead an individual to be hopeful and have a creative life. Would the opposite be possible? To be envious and at the same time creative and hopeful? Based on Freudian Dualism drive, which Klein did not give up in the construction of her metapsychology, we answer yes, primarily from the introjection of the good object, which allows the elaboration of envy, an element that we will emphasize from the figure of the analyst in the clinical process. To elucidate each of these elements, we will use the short story "The foreign legion" by Clarice Lispector (1999) as a guiding thread throughout the text.

Cet article discute le texte fondateur de Melanie Klein, "Envie et gratitude" 27 (1957), afin de l'articuler avec les phénomènes de l'espoir, du désespoir, de la créativité et de la destructivité. Au cours de notre lecture, nous avons observé que l'envie est un terreau fertile pour la croissance du désespoir et de la destructivité. En revanche, la capacité à être reconnaisant peut conduire les individus à être plein d'espoir et à mener une vie créative. Le contraire serait-il possible? Être envieux et en même temps créatif et plein d'espoir? Sur la base du dualisme pulsionnel freudien, que Klein n'a pas abandonné dans la construction de sa métapsychologie, nous répondons par l'affirmative, notamment par l'introjection du bon objet qui permet d'élaborer l'envie, élément que nous soulignerons à travers la figure de l'analyste dans le processus clinique. Afin d'élucider chacun de ces éléments, nous utiliserons la nouvelle "La Légion étrangère" (1999) de Clarice Lispector comme fil conducteur tout au long du texte.

RESUMEN

Introduction: The role of dispositional gratitude as a positive psychological resource and prosocial personality trait in real life interactions militates in favor of its introduction to the research field of social media. Methods: Based on a literature review of the previously studied relationship of dispositional gratitude with social comparison and envy in offline settings, a twofold moderation model was proposed and quantitatively tested in a cross-sectional sample of N = 268 Instagram users aged between 18 and 40 years. Additionally, the dual conceptualization of benign and malicious envy was scrutinized by validating its respective connections with affective outcomes and inspiration on Instagram. Results and discussion: Dispositional gratitude serves as a protective factor when using Instagram by significantly mitigating the relationship of social comparison and malicious as well as general envy on Instagram. Furthermore, the results support the more nuanced understanding of envy as a dual construct in the face of social media use.

RESUMEN

Temporary agency workers are becoming increasingly critical as a supplementary workforce within enterprises, inevitably leading upward social comparisons with permanent employees. However, existing research pays little attention to this phenomenon, which cannot provide theoretical guidance for the management of temporary agency workers. To fill this gap, our study utilizes the cognitive appraisal theory of emotion to construct a dual-path moderated mediation model, examining how upward social comparison is associated with positive and negative behaviors through two distinct forms of envy. Through the questionnaire survey, data is collected from 882 temporary agency workers in a Chinese temporary staffing firm. The results reveal that upward social comparison is associated with both benign and malicious envy, which in turn respectively relate to informal workplace learning and social undermining behavior. Additionally, psychological availability moderates the relationship between upward social comparison and envy, such that when psychological availability is higher (vs lower), the positive effect of upward social comparison on benign envy is stronger and the positive effect of upward social comparison on malicious envy is weaker. Moreover, psychological availability further moderates the indirect effect of upward social comparison on employee behavior. When psychological availability is higher (vs lower), the positive indirect effect of upward social comparison on informal workplace learning via benign envy is stronger, whereas the positive indirect effect of upward social comparison on social undermining via malicious envy is weaker. Our study enriches the theoretical research perspective of upward social comparison and provides insights for managing temporary agency workers. Our study is the first to explore the dual behavioral choices of upward social comparison of temporary agency workers and apply the cognitive appraisal theory of emotion to social comparison. The results indicate that organizations can improve the psychological availability of temporary agency workers to stimulate learning behavior and reduce social undermining behavior to achieve a win-win situation between temporary agency workers and organizations.

RESUMEN

To prevent the great dangers caused by emergency situations, providing rapid and high-quality emergency aid highly depends on the location of emergency medical centers. The purpose of this research is to present a multi-objective mathematical programing model based on the minimum P-envy algorithm to locate and construct emergency medical services (EMS). Maximizing the coverage in order to increase the probability of survival of different categories of patients, minimizing the costs of constructing EMS and optimizing the ratio of regions having the right to emergency medical services is one of the fundamental challenges in the health care system of countries. In this paper, a model for maximum utilization of EMS considering budget limitations is presented. In this study, since the problem is NP-Hard, the Genetic Algorithm (GA) and Simulated Annealing (SA) algorithm were used to solve this problem. The parameters of the metaheuristic algorithms were tuned using the Taguchi method. Several instance problems were solved to compare the performance of 2 algorithms. The results demonstrate that the validity of the proposed model. Also, the mean of the solutions obtained by GA for small, medium, and large-size problems are better than the SA algorithm. Also, the GA algorithm obtained more efficient solutions than the SA algorithm.
