Abstract:
Dealing with different supply chain risks and how firms should prepare against them has become an important issue in real world application. In this paper, we propose a periodic model to fortify supply chain structure against disruption by remanufacturing different types of returned products at first priority and manufacturing raw materials at second priority only if it is necessary. Additionally, our approach to model disruption is that there are two kinds of facilities for manufacturing/ remanufacturing centers. The first one is reliable and the second one is unreliable. Therefore, in this paper, we formulate and solve a reliable discrete dynamic linear programming with different types of returns in finite horizon. To simplify and solve the problem, we propose a two-stage optimal policy considering both deterministic and stochastic demand and returned products. Our results and analysis show the flexibility and cost efficiency of our reliable model in different situations with different type of returned products. In addition, we present a managerial policy to identify which type of manufacture or remanufacture facilities should use in each period
