Our supply chain 19 2019 consists of one manufacturer multiple suppliers and multiple distribution centers. While one Accepted April 30 2019 Available online objective is to minimize the total costs of logistics that consists of purchasing cost production April 30 2019 cost and distribution cost the other objective is to maximize total value of purchasing. These Keywords objectives are in conflict with each other. In this paper the fuzzy multi-objective linear model Supply Chain Master Planning is applied with -Cut analysis to achieve the optimal supply chain master planning in an Possibilistic Linear Programming uncertain environment by balancing these two conflicting objectives. The -Cut analysis is Conflicting Objective introduced to ensure decision-makers that the outcome satisfies their preferences based on a Fuzzy Goal Programming specified minimum allowed satisfaction value . α-Cut Analysis 2019 by the authors licensee Growing Science Canada. 1. Introduction A Supply Chain SC is a chain or network that coordinates the activities of five individual segments supplier manufacturer distribution center retailer and customer for serving products or services to satisfy customer requirements.
