Abstract

An essential component of managing inventories involves making the right decisions at the right time. Decisions are made by the vendor rather than the buyer’s representatives in a vendor-managed inventory system. The proposed study is intended for only one buyer and vendor with a single type of deteriorating product. Transportation of inventory from vendor to buyer is main aspect of inventory management. Due to transportation system, carbon emitted in environment. To minimize the carbon emission, green investment technology used for sustain environment. In this article, developed a VMI model and traditional buyer model with demand is depending on green investment and its promotion level. The objective is to minimize total cost per time unit of supply chain with respect to optimal replenishment cycle time and green investment cost. The suggested model is validated with a numerical example and sensitivity analysis, and the results demonstrate that the VMI model performs better than the traditional buyer model.
