Strategies of delay delivery and controllable lead time in supply chain consignment inventory

This paper describes about two strategies in consignment inventory based supply chain with controllable lead time and delaying last delivery comprising a two level supply chain involving single vendor and multi buyers. This model would give minimum joint total expected cost of the strategies involving vendor and buyer, simultaneously to optimize quantitative decision variables. Numerical examples are presented to demonstrate the benefit of the proposed strategies and the effect of changes on the cost and parameters are studied.
