Green Supplier Selection Using Fuzzy AHP, Fuzzy TOSIS, and Fuzzy WASPAS: A Case Study of the Moroccan Automotive Industry

Programmable Logic Controllers (PLCs) are indispensable for current and future industrial development, especially in smart factories, smart home technology, automated production lines, and machinery manufacturing. This study presents the trends in PLC software and hardware development through a technology roadmap and offers relevant suggestions to help industries achieve sustainable development, enhance market competitiveness, and provide references for research. Through expert interviews and fuzzy Delphi analysis, this study points out that future PLC development needs to focus on editing interfaces, syntax, Central Processing Units, Memory Units, and Communication Modules. Specific recommendations include visualizing regional/global label settings and connection settings, adding Python, JAVA, LabVIEW, and Scratch syntax, improving instruction execution speed, expanding program and expansion capacities, and adopting dual-channel Ethernet and connections to external networks and wireless networks. Fuzzy hierarchical analysis shows that Communication Modules are the most important component, followed by Central Processing Units and syntax expansion, and, finally, program and expansion capacity enhancements. These suggestions aim to promote product innovation and social environment demand evaluation, enhance product competitiveness, and achieve sustainable development goals.

In recent years, procurement managers have introduced environmental considerations into supplier selection and evaluation as a response to strict environmental regulations implemented by governments. Although previous research investigated the selection of eco-friendly suppliers, little research has been conducted on the significance of the wide range of selection criteria used by industrial customers. The aim of this study was to address this gap and examine the difference in the perceived importance of the selection criteria versus the performance achieved using the selection criteria, in addition to the difference in the business performance and the total supply performance. By investigating the selection criteria of manufacturers in the market environment, this study aimed to demonstrate how their business performance was affected by the performance of suppliers in relation to such criteria. To accomplish this task, this study conducted an empirical analysis based on the questionnaire responses of 72 purchasing managers working in the electrical/electronic and heavy chemical industries. Based on previous research, the following six supplier selection factors were identified: eco-friendliness, quality, relationship, flexibility, delivery, and price/finance. By using statistical analyses, including sample t-tests and multiple regression analysis, this study identified a correlation between supplier and manufacturer performance. The findings show that some factors, such as eco-friendliness, flexibility, price, and delivery, were statistically relevant to the performance of manufacturers, which added value to the decision-making strategy employed in supplier selection.

This study explores the challenges and solutions faced by manufacturing companies in one industry when integrating green suppliers into their supply chains. The FGD transcripts were analyzed using NVivo 12 Pro for coding and thematic analysis, which helped identify key challenges and solutions. The key challenges identified included higher procurement costs, limited availability of green materials, quality assurance issues, and difficulties in verifying green practices. Strategic solutions involve establishing partnership strategies, conducting supply chain audits, and developing clear evaluation criteria. The content analysis shows that higher procurement costs can be mitigated through strategic partnerships offering better terms and pricing stability. Diversifying the supplier base and investing in supplier development programs address the limited availability of green materials. Quality assurance is maintained through stringent controls and regular audits, while verification challenges are managed with third-party certifications and robust audits to prevent greenwashing. The SWOT analysis highlights strengths such as strategic partnerships and regular audits, opportunities like developing evaluation criteria and technological advancements, and acknowledges weaknesses and threats. This comprehensive analysis provides a nuanced understanding of the practical challenges and solutions in green supply chain management, offering a strategic framework for manufacturing companies to enhance sustainability and achieve competitive advantage.
