Boonsothonsatit, G., 2017. Generic decision support system to LEverage supply chain performance (GLE) for SMEs in Thailand. Journal of Manufacturing Technology and Management, 28(6), pp.737-748
Abstract
Propose – This paper explains the development stages of a Generic decision support system to LEverage supply chain performance (GLE). It aims to identify and tradeoff the critical supply chain measures which are interrelated and in contradiction with each other.
Design/methodology/approach – The GLE was developed as an extension of the supply chain performance assessment tool (SCPAT) proposed by Banomyong and Supatn (2011). It contained nine measures covering key activities along the supply chain under dimensions of cost, time, and reliability. Their interrelations were figured out by causal linkages, whereas their contradictions were traded off as multi-objective optimization. It is solved using fuzzy goal programming (FGP) along with a weighted max-min operator in order to acquire the Pareto-optimal solution.
Findings – The results from the GLE showed there were two critical supply chain measures including supply chain cost per sales and average order cycle time. They were contradictorily influenced by a root-cause, namely product lot-size. Its Pareto-optimal value was provided to achieve the minimized values of supply chain cost per sales and average order cycle time which were consistent with their relative weights.
Research limitations/implications – As generic features, the GLE needs further validation in several industries under various supply chain strategies. The further validation may contribute the GLE to include multiple decision variables, multiple types of product, and multiple periods of time. In addition, the GLE may consider a dimensional measure of environmental impact along the supply chain activities.
Originality/value – The GLE is a unique decision support system to identify and trade-off the critical, interrelated and contradicting supply chain measures. The more uniqueness is obtained when the GLE offers an option of inputting a set of relative weights for the interrelated supply chain measures.
