Abstract

In recognition of suppliers' vital role in the supply chain, manufacturing firms need to manage and develop their suppliers in line with two keys requirements; sustainability and responsiveness performance. A good relationship between manufacturers and a competent network of suppliers is required. Therefore, manufacturing firms may engage through the supplier development (SD) program. However, there is an extensive number of practices in SD, sustainable manufacturing (SM) and responsive manufacturing (RM). The impacts of each practice are diverse and not contribute equally, yet the manufacturing firms also have a limited resource. The manufacturing firms need to carefully and wisely identify which practices are more suitable for their operations environment to localise their investment for saving time, money and resources. Thus, the need for a framework to provide important information on which practices should be focused on is crucial. The selection of practices led to multi-criteria decision making (MCDM) problem. For those reasons, the MCDM method needs to be employed in the evaluation and decision-making process. Hence, this study is carried out to investigate the practices in SD, SM and RM implemented by Malaysian manufacturing firms. The survey data were collected from ISO14001 certified manufacturing firms in Malaysia as registered in Standard and Industrial Research Institute of Malaysia (SIRIM) database. Of 264 questionnaires, 78 questionnaires were returned, and only 71 (26.89%) questionnaires with completed information were accepted for further analysis. A preliminary analysis indicates that the implementation of the SD program had a significant relationship with SM and RM. From factor analysis, SD practices were extracted into five main factors, namely, Supplier Certification (SC), Green Capability (GC), Investment and Resource Transfer (IRT), Feedback and Evaluation (FE) and Knowledge Transfer (KT). Among the factors, KT produces significant, positive relationships to the three pillars of SM; economic, environmental and social. KT also significantly, positively correlate with RM. To develop the framework, the fuzzy logic and Analytic Hierarchy Process (AHP) were integrated. The results show that the priorities for SD practices associated with KT (0.247), SC (0.221), FE (0.201), GC (0.195), IRT (0.135). For SM, the priorities ranked by environmental (0.422), economic (0.333) and social (0.245) whereas, for RM, responsiveness (1.000) solely factorised and consists of seven practices. The research is beneficial to provide important information, particularly to industrial practitioners, to identify which practices need to be focused on, so investment in the supplier development programs can be localised wisely. This research significantly affects saving time, money, and resources in enhancing suppliers' capabilities who contribute to the movement of the supply chain and eventually enhance the manufacturing sustainability and responsiveness.
