maintenance supplier selection: evaluating the effect of maintenance and sourcing strategies

The advent of globalization and outsourcing of products and services has resulted in more networked, highly dependent firms in supply chains; so supply chains’ vulnerability to several risks such as equipment breakdown is increased. although optimizing maintenance supplier selection has a vital role in supply chain performance, it has not received enough attention in the literature. due to the effect of maintenance strategies and supplier selection approaches, in this paper, three scenarios are considered based on various strategies as follows: 1-preventive maintenance with single supplier selection (pms), 2- preventive maintenance with multiple supplier selection (pmm), and 3-condition based maintenance with multiple supplier selection (cbmm). a fuzzy goal programming approach is applied to make trade-offs between several objectives. the efficacy of the model is validated through numerical examples, and results are compared to investigate the effect of implementing each scenario. the results show that in situations that reducing unreliability cost has higher priority for a decision-maker, cbmm is more efficient than other scenarios.
