Integrated Inventory Model With Controllable Lead Time Involving Investment For Quality Improvement In Supply Chain System With Environmental Sustainability

Abstract

In this study, we consider integrated inventory model with controllable lead time involving investment for quality improvement in supply chain system.The lead time is identical for all buyers as well as it can be shortened by paying an additional crashing cost which is exponentially function of lead time.To find out an optimal inventory strategy that can minimize the value of the integrated total relevant cost with the concern of environmental sustainability. Finally, a numerical example is presented to illustrate the proposed model.
