Some formulations for optimal solutions with delays in payment and price-discount offers in the supply chain system

Both the trade credit and cash discount are two important managerial considerations. Sana and Chaudhuri (2008) [13] incorporate them to establish a deterministic EOQ model with delays in payments and price-discount offers. Basically, their modeling is correct and interesting. However, they do not provide a concrete solution procedure to locate the optimal solution. So, the main purpose of this paper is to complement their drawbacks to present a complete solution procedure for finding the optimal solution. Furthermore, when the optimal solution exists, this paper even develops the formulation for it.
