This research applied Selective Regeneration Particle Swarm Optimization (SRPSO) for two-stage supply chain inventory classification problems. In SRPSO, In order to increase the efficiency, suggestion on parameter settings is made and a mechanism is designed to prevent particles fall into the local optimal. This research is assumed that an inventory classification is performed to properly categ...

Global warming and climate change become a sensitive issue worldwide, many countries try to control the CO 2 emissions by investigating in projects. This study proposes sustainable inventory model reduce carbon emission. It is generally assumed that demand increasing at starting of an level decreasing ending for particular newly launched product. In this situation, usually represented Normal di...

In this paper a deterministic inventory model with imperfect quality have been developed for deteriorating items with two parameters Weibull distribution deterioration and time dependent holding cost. Shortages are allowed and are completely backlogged. The model has been framed to study the items whose deterioration rate increase with time under permissible delay in payments with imperfect qua...
