Application of Analytic Hierarchy Process Together with Simple Additive Weighting Methods for Raw Materials Supplier Selection of Crispy Pork Factory
Keywords:
Raw Materials Supplier Selection, Analytic Hierarchy Process, Simple Additive WeightingAbstract
The objective of this research was to determine the criteria and methods for selecting the suitable raw material supplier for the crispy pork factory under the COVID-19 epidemic situation. The followings are research results. First of all, literature review showed that there were total of seven criteria for selecting suitable suppliers which obtained by weighted average method. The seven criteria are price, quality, delivery, supplier’s reliability, delivery’s completeness, payment pattern, and crisis management. Especially in the current situation with the epidemic of COVID-19, therefore the crisis management was considered the second most important criterion after the quality. Secondly, in a case study, the seven criteria were applied to select the most suitable supplier from three suppliers and three methods; Analytic Hierarchy Process (AHP), Simple Additive Weighting (SAW), and Analytic Hierarchy Process Together with Simple Additive Weighting (AHP-SAW) were used. The results showed that all three methods yielded the same supplier ranking as Supplier A> Supplier B >Supplier C. Finally, the priority score of AHP-SAW was the highest compared to the others. Therefore, this AHP-SAW method was seemed to be the most reliable and able to solve other industries and related problems.
