Bi-Objective Mathematical Formulation for Green Supply Chain consideringProduct Life Cycle Capability

The aim of the paper is to develop a mathematical model ina four-layer supply chain using the product life cyclefactors to obtain the optimal number of products and thefulfillment of an operation in product life cycle. In theproposed four-layer supply chain including supplier,manufacturer, distributor and customers’ product life cycleencompasses several operations. The process capability isincluded in the formulation as a quality measure to increaseservice satisfaction. The problem is modeled to minimizethe total cost of the system and maximize the processcapability. The proposed bi-objective model was handledand a linearization is performed to facilitate optimizationprocess. An application example is illustrated to verify theeffectiveness of the proposed methodology.
