Abstract
This paper is aimed at suggesting a methodology leading to effective
supplier management processes utilizing information obtained from
the supplier selection processes. For this methodology, we propose
the supplier selection and management system (SSMS) that includes
purchasing strategy system, supplier selection system, and supplier
management system, and we explain how the SSMS is applied to a real
supply chain. The methodology identifies the managerial criteria
using information derived from supplier selection process and makes
use of them in the supplier management process. These managerial
criteria include key criteria that are major criteria required by
the manufacturer for the best quality of parts from suppliers according
to the character of each part, and weak criteria that show the shortcomings
of selected suppliers as compared with alternative suppliers with
regard to each criterion. The effectiveness of supplier management
with managerial criteria was verified by a t-test and a correlation
analysis with the example of a Korean air conditioner manufacturer
