The coronavirus (COVID-19) outbreak is causing widespread concern and economic hardship for consumers, businesses, and communities across the globe. This caused significant financial losses to the business entrepreneurs especially minority-owned enterprises in the fashion industry. This circumstance has pushed foresight as a prominent concept for organizations operating in this current environment. This study aims to identify the level of technology foresight amongst business survival in local fashion retailers and also to determine the relationship between technology foresight towards business survival in the fashion retail industry during post-Covid-19. This research adopts a quantitative, descriptive, and correlation study. Data were collected through an online questionnaire, which involved 170 fashion retailers in Bangi, Selangor. A Spearman’s Rho correlation analysis was used to test the hypotheses. The result shows that there is a significant relationship between industry dynamism, environmental scanning, and networking ties toward business survival. This study concludes that micro-business or fashion retail businesses should highlight the importance of technology foresight in their ability interprets environmental changes to assure the company's continued existence over the long term.

Medical students constitute a small part of the university population and are young people with high level of knowledge and creativity that the state focuses on training. They are important human resources to meet the industrial expectations, typically for national health. The employment of medical college graduates is not only related to the happiness of thousands of families, but also related to the quality of people's life and health, economic development, and social stability in China. In the face of increasingly severe employment situation, how to alleviate the "employment difficulty" of college students has aroused widespread concern in the society. In career planning education, the medical college students should be encouraged to know themselves, improve themselves, and improve their employment competitiveness. At present, the career planning education of college students in China still remains at the level of employment guidance, which needs to be constantly improved. The discussion on the service dimensions that need to be provided for the career planning of medical college students is not thorough and comprehensive. On the basis of the existing research, from the perspective of education, management and other disciplines, guided by relevant theories, this paper discusses the service dimensions of medical university students' career planning in a more in-depth and systematic way by using literature research methods. This paper follows the research idea of "status investigation -- finding problems -- suggestions". First in this paper, the medical college students' career planning service involved in the core concepts and related theories, and then influence the effect of medical college students' career planning services dimension analysis of the status quo to find the main problems and the reasons put forward to further strengthen and improve the service effect of medical college students' career planning. The service quality gap model is discussed and a career planning service quality framework is proposed.

Carbon emissions were one of the most critical contributors to climate change, and the recent climate agreement had agreed for all participating countries to reduce their emissions. Malaysia has pledged to reduce 45 per cent of its carbon emissions by 2025. However, reducing carbon emissions from the industry was still limited due to voluntary reporting, particularly among manufacturers. Thus, it is ambitious for the Malaysian government to achieve its target by 2025. A complete review is performed to go through the literature and determine the review's research path. This review aims to investigate the low carbon performance based on the manufacturing industry's low carbon supply chain practices. The findings show that low carbon production was insignificant in reducing overall carbon emissions. In contrast, the rest of the low carbon supply chain practices were by the Natural Resource-Based-View (NRBV) theory. It helps to identify companies' low carbon supply chain practices to reduce carbon emissions and meet environmental regulations. Additionally, the review also provided new insight into mediating effect that contributes to the organizational theory of NRBV. The theoretical hypotheses were tested with bias-corrected and accelerated (BCA) bootstrap confidence intervals. The instrument used in this review is a questionnaire, and the questionnaire consists of five (5) scales which tapped on (LCSCM), energy management, and low carbon performance. Responses from the respondent were collected via an online survey between Malaysian manufacturing industries. SmartPLS was used to perform the model and structural analyses. The result shows that LCSCM influence carbon performance directly and indirectly, so the hypotheses are supported. This review is one of the earliest attempts to record empirical evidence regarding companies’ low carbon supply chain practices and performance. Thus, the review shows results can be used and extended to develop low-carbon supply chain frameworks.

Working business management students were among those who were affected by the COVID-19 pandemic when it comes to managing their finances. This study focuses on the level of financial management of working business students during the pandemic in three areas namely financial literacy, financial planning, and financial behavior. A descriptive research design was utilized by the researchers in the conduct of the study. There were 200 business students who are working who participated in this study. They were chosen through purposive sampling. A standardized survey questionnaire was formulated by the researchers and was sent out and retrieved via Google Forms. Kruskal-Wallis and Mann-Whitney U tests were used by the researchers to test the significant difference between indicators and the profile of the respondents. Results showed that there is a very high level of financial management among those students who are working in terms of the three indicators namely financial literacy, financial planning, and financial behavior. Results showed that financial planning has the highest mean among the three indicators which means it is highly practiced by working business students. It was also revealed in the study that there was no significant difference in terms of financial literacy and financial behavior when analyzed according to the profile of the respondents. There was, however, a significant difference in terms of financial planning and the year-level profile of the respondents. Financial management plays a vital role among working business students as this translate into how well they manage their financial resources.

Purpose: Correlation-based storage assignment approach has been intensively explored during the last three decades to improve the order picking efficiency. The purpose of this study is to present a comprehensive assessment of the literature about the state-of-the-art techniques used to solve correlated storage location assignment problems (CSLAP).Design/methodology/approach: A systematic literature review has been carried out based on content analysis to identify, select, analyze, and critically summarize all the studies available on CSLAP. This study begins with the selection of relevant keywords, and narrowing down the selected papers based on various criteria.Findings: Most correlated storage assignment problems are expressed as NP-hard integer programming models. The studies have revealed that CSLAP is evaluated with many approaches. The solution methods can be mainly categorized into heuristic approach, meta-heuristic approach, and data mining approach. With the advancement of computing power, researchers have taken up the challenge of solving more complex storage assignment problems. Furthermore, applications of the models developed are being tested on actual industry data to comprehend the efficiency of the models.Practical implications: The content of this article can be used as a guide to help practitioners and researchers to become adequately knowledgeable on CSLAP for their future work.Originality/value: Since there has been no recent state-of-the-art evaluation of CSLAP, this paper fills that need by systematizing and unifying recent work and identifying future research scopes.

Purpose: This study tests and analyzes whether: (a) Green logistics has positive effect on circular economy implementation, (b) Absorptive capacity has positive effect on circular economy implementation, (c) CE implementation has positive effect on Business Sustainability, (d) the role of CE implementation in mediating the effect of Green logistics on Business Sustainability, and (e) the role of CE Implementation in mediating the effect of Absorptive capacity on Business SustainabilityDesign/methodology: Researchers use a quantitative approach, the population is all natural-colored batik SMEs in the Provinces of Central Java and West Java. Respondents are owners/managers of batik SMEs with a target sample of 250 SMEs. Meanwhile, based on purposive sampling of data collection, it turns out that 228 SMEs are returned and deserved to be processed. The statistical technique uses Structural Equation Modeling with Partial Least Square.Findings: This study finds that there is a significant positive effect of; (a) Green logistics for circular economy implementation, (b) Absorptive capacity for circular economy implementation, (c) CE implementation for Business Sustainability. Furthermore, CE implementation mediates Green logistics for Business Sustainability, and (e) CE implementation mediates Absorptive capacity on Business Sustainability.Research limitations/implications: The implementation of the circular economy in the SMEs studied is practiced in a simple way. The role of mediation can consider other variables that are no less important in the context of batik SMEs that use natural colors. Respondents are only represented by SME groups in associations in the Klaten (Central Java) and Ciwaringin (West Java) regions, so it is feared that they would not be able to generalize the natural color batik SME population in Indonesia. It is recommended that in the future research considers longitudinal studies using the perspective of multiple respondents so that they are not subjective. Managerial Implication: Business processes in SMEs based on natural colors should consider green logistics aspects because it will have positive impact in the long term, especially on Business Sustainability. In improving SME Business Sustainability, it is necessary to conduct Absorptive capacity consistently, continue, and has consistent commitment. This is important in order to increase the competence of SMEs. When all resources are good, CE implementation practices can be more practiced by integrating with existing business processes.Theoretical Implication: This study provides enrichment to the literature on circular economy implementation in SMEs that are influenced by green logistics and absorptive capacity. The impact can make a significant contribution to increase business sustainability (business, social, and environmental performance).Originality/value: This study has its originality due to the lack of study examining circular economy implementation in the context of

The impact can make a significant contribution to increase business sustainability (business, social, and environmental performance).Originality/value: This study has its originality due to the lack of study examining circular economy implementation in the context of","PeriodicalId":38526,"journal":{"name":"International Journal of Industrial Engineering and Management","volume":"90 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2023-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79936532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Purpose: We consider the problem of route planning of multiple rechargeable heterogeneous UAVs with multiple trips under mission time and payload carrying constraints. The goal is to determine the types and number of UAVs to be deployed and their flying paths that minimizes the monetary cost, which is a sum of the recharging energy cost of each UAV, the UAV rental cost, and the cost of violating the mission time deadline.Design/methodology/approach: The problem is formulated as a mixed integer programming (MIP). Then, the genetic algorithm (GA) is developed to solve the model and the solutions are compared to those obtained from the exact method (Branch-and-Bound). Novel chromosome encoding and population initializations are designed, and standard procedures for crossover and mutation are adapted to this work. Test problems on grid networks and real terrains are used to evaluate the runtime efficiency and solution optimality, and the sensitivity of GA parameters is studied based on two-level factorial experiments.Findings: The proposed GA method can find optimal solutions for small problem sizes but with much less computation time than the exact method. For larger problem sizes, the exact method failed to find optimal solutions within the limits of time and disk space constraints (24 hours and 500 GB) while the GA method yields the solutions within a few minutes with as high as 49% better objective values. Also, the proposed GA method is shown to well explore the solution space based on the variation of the total costs obtained.Originality/value: The unique aspects of this work are that the model optimizes the sum of three different costs – the electricity recharging cost, the UAV rental cost, the penalty cost for mission deadline violation, and the recharging period based on the remaining energy, the payload capacity, and the heterogeneity of UAVs are incorporated into the model. The model is formulated as a mixed integer programming and the genetic algorithm is developed to solve the program. Novel chromosome encoding and population initializations are designed, and standard procedures for crossover and mutation are adapted to this work.
