An easy approach to derive a buyer-vendor EOQ model with changeable lead-time in supply chain

摘要

Hsiao and Lin {International Journal of Advanced Manufacturing Technology, published online: 7 April 2004) discussed Stackelberg game in supply chain and investigated the supplier's optimal lead time and the retailer's optimal cycle time. But the authors just derived the approximate solution of the optimal lead time and optimal cycle time. Recently, Huang and Hsu (Journal of Information & Optimization Sciences, Vol. 29 (2008), pp. 305-310) offered an algebraic approach to find the exact optimal lead time and optimal cycle time in the constant marker's demand rate situation. In addition, Huang et al. found that their exact solution is better than Hsiao and Lin's approximate solution from the numerical examples. In this paper, we will offer another simple approach to derive Hsiao and Lin's model and find the exact solution same as Huang and Hsu.
