Coordination in the supply chain considering total lead times and delivery times

This study considers a two-echelon supply chain (SC) consisting of single vendor and buyer by reducing delivery time. paper examines time optimization as an essential component lead times. The length production are studied simultaneously. decision variable is considered in the proposed model. Reducing vital incentive factor encouraging to participate coordinated model guarantee profitability. A suggested mathematical profit functions both participants (i.e., buyer) investigated under two decision-making scenarios: decentralized structure structure. analyses show that our ensures better performance for makes whole process more profitable adequate sharing risks between participants. In other words, model, decreasing buyer's shortage costs increasing order quantity leads increase buyer.
