A Fuzzy Model for A Multistage Supply Chain System Controlled By Kanban

: This paper deals with a multi-machine supply chain system operating under just-intimedelivery policy with fuzzy demands. For this purpose, the system is modeled as a fuzzylinear programming problem. In JIT delivery policy, kanban has the role of a transporter. Bythe solution of the related fuzzy linear programming problem, the number of kanbans isdetermined optimally. Fuzzy demands method enables one to minimize inventory costs underuncertain demand fluctuations.
