Green-component life-cycle value on design and reverse manufacturing in semi-closed supply chain

Due to increasing competitive pressure, shortened life cycle and environmental consciousness, more attentions have been paid to resource usage reduction and ecology protection. Green product design has received much attention recently, because product design significantly influences the cost of disassembly, component inspection and repair, remanufacturing and recycling. We investigate the impact of the green product design, the new technology evolution and remanufacturing on the production-inventory policy, and develop an integrated deteriorating inventory model with green-component lifecycle value design and remanufacturing. We provide time-weighted inventory (TWI) approach to analyze the saw-tooth inventory for the replenishment policy of the integrated production-inventory deteriorating model. A numerical example is also presented to illustrate the theory. The results show that the new technology evolution, take-back ratio and the system's holding costs are the critical factors affecting the decision-making in a green supply chain inventory control.
