The literature on social capital is utilized to construct hypotheses about the cognitive, structural, and relational factors that may influence decisions to purchase from minority enterprises. Following that, current discrimination theory is used to deduce how buyers' views about supplier diversity affect the effects of social capital on their buying operations with EMBs. Multiple regression research indicates that in both the United States and the United Kingdom, buyers' perceived positive social capital has a direct, substantial association with their spending with EMBs. Additionally, the findings indicate that in both nations, purchasers' attitudes toward supplier diversity act as a moderator of the connection. Interestingly, despite the fact that the United States pioneered the concept of supplier variety, our study reveals that UK LPO buyers spend more with their EMBs. This research demonstrates how LPOs' strategic corporate social responsibility initiatives may be influenced by their buyers' social relationships with EMBs and their views about supplier diversity, based on these findings.","PeriodicalId":37135,"journal":{"name":"International Journal of Supply and Operations Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46100714","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}

Charkaoui","doi":"10.22034/2019.1.3","DOIUrl":"https://doi.org/10.22034/2019.1.3","url":null,"abstract":"In this paper, we propose a credibility-based fuzzy mathematical programming model for integrating the production and distribution in a milk supply chain under uncertainty. The proposed model is a mixed integer linear programming, which takes into account technological constraints and aims to maximize the total profit including the total costs such as production, storage, and distribution. To bring the model closer to real-world planning problems, the objective function coefficients (e.g. production cost, inventory holding and transport costs) and other parameters (e.g. demand, production capacity, and safety stock level) are all considered fuzzy numbers. In the uncertain environment, the most known criteria widely employed are optimistic and pessimistic value criterions. Both criteria present some deficiency. For the optimistic criterion, it suggests an audacious decision maker who is attracted by high payoffs (low cost), while for the pessimistic criterion, it suggests a conservative decision-maker who tries to make sure that in the case of an unfavorable outcome (loss), there is at least (in most) a known minimum payoff (maximum loss). The Hurwicz criterion is used to overcome these problems. By varying the value of θ, it can balance the optimistic and pessimistic levels of the decision makers. Moreover, the different property of the credibility measure is used to build the crisp equivalent model, which is a MILP model that can solve problems by using a commercial solver such as GAMS. Finally, numerical results are reported for a real case study to demonstrate the efficiency and applicability of the proposed model.","PeriodicalId":37135,"journal":{"name":"International Journal of Supply and Operations Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67980301","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}

I develop and test theory in this article about motor carriers' longitudinal performance on three categories of safety behaviors associated with accident rates—Unsafe Driving, Hours-of-Service Compliance, and Vehicle Maintenance—as tracked by the Federal Motor Carrier Safety Administration as part of the Compliance, Safety, and Accountability (CSA) program. I specifically draw on fundamental concepts from sociological agency theory and resource dependency theory to develop a middle-range theory that generates previously untested hypotheses about carriers' longitudinal safety performance for these classes of safety behaviors following the CSA program's inception. The hypotheses are investigated by fitting a series of multivariate latent curve models to four years of panel data for 484 big for-hire vehicle carriers operating in the United States. The empirical findings confirm the theoretical expectations and persist during robustness testing. These findings have significant consequences for academics, motor carrier executives, purchasers of motor carrier transportation services, and policymakers.","PeriodicalId":37135,"journal":{"name":"International Journal of Supply and Operations Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48704619","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}

The objective of this article is to contribute to the development of SCM theory by examining the potential effects of Big Data Analytics on information utilization in a business and supply chain setting. Because it is critical for supply chain firms to have access to current, accurate, and useful data, the exploratory research will shed light on the opportunities and problems associated with the implementation of Big Data Analytics in SCM. While management is increasingly focusing on Big Data Analytics, actual research on the subject is still sparse. Due of the scarcity of relevant content at the nexus of Big Data Analytics and Supply Chain Management, the authors employ the Delphi research technique. The given Delphi survey findings complement to existing knowledge by identifying 43 opportunities and problems associated with the emergence of Big Data Analytics from a corporate and supply chain perspective. These structures provide the research community with a starting point for tailoring future research at the nexus of Big Data Analytics and SCM. The research contributes to the current body of knowledge by examining possibilities and challenges at the corporate and supply chain level with a particular emphasis on the consequences imposed by Big Data Analytics.","PeriodicalId":37135,"journal":{"name":"International Journal of Supply and Operations Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45054395","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}
