Supplier evaluation with order allocation in mega-projects.

Purpose: The purpose of this study is to provide a model for evaluating, prioritizing and allocating orders to suppliers in the supply chain for mega-projects. Design/methodology/approach: By using an integrated model (based on fuzzy analytic network process), suppliers are selected and the appropriate amounts are allocated to them in mega-projects. Initially, a hierarchical model of the research method was introduced. Then, the results on reliability and validity analysis of research measurement tools were presented. Finally, prioritization and allocation of orders to suppliers, with a case study of Iran Mall project, was carried out using Decision Making Trial and Evaluation Laboratory (DEMATEL) and analytic network process (ANP). T-test was used to evaluate the research hypotheses. Findings: The findings were examined against conventional numerical analysis techniques. Finally, implication and recommendations for future work were presented. Originality/value: The originality of this work is about using multi-criteria decision-making techniques for evaluating suppliers in mega-projects. [ABSTRACT FROM AUTHOR]
