Sustainable Multi-period Production with Core and Adjacent Product Portfolio

Abstract

Manufacturing and service companies need to increase service level to ensure their survival. However, in recent years this is not the only problem with production systems, the environmental impact became a major concern for manufacturing and service companies alike. In this article, we jointly consider time, cost, and environmental impact for production planning. To achieve this goal, collaborative decision-making with three decision-makers (DMs) is assumed to adjust sustainability performance through choosing the most suitable production type and appropriate production day. Financial managers, industrial managers, and environmental managers are three decision-makers who collaborate to improve responsiveness, and to reduce total production cost, and CO2 emissions sequentially. To this end, a mixed-integer multi-objective mathematical model is suggested; Ɛ-constraint is used to solve the model. With the proposed model, DMs can make decisions on which products are produced on which day in a way to have trade-off among indicators.
