The inventory routing problem (IRP) is an integration of vehicle and management problems. In the recent years, it has increasingly drawn attention researchers because its potentially significant practical value. IRP classified as NP-hard since subsumes (VRP). This fact led to development many heuristic or metaheuristic approaches, although a small number exact methods have been introduced recen...

• We study the Inventory Routing Problem with Time Windows (IRPTW). provide a mixed integer linear programming formulation that includes both arc and routebased variables. develop an efficient branch-price-and-cut algorithm to solve IRPTW optimally. generate two sets of data considering time-varying time-invariant demands at retailers. demonstrate efficacy our solution approach through computat...

Abstract The uncertain production-inventory problem with deteriorating items is investigated and an optimal control model developed in the present paper. perturbed by canonical process. Based on uncertainty theory, optimistic-value optimal-based established. study aims to find optimistic value of revenue at a certain confidence level. theory used obtain equation optimality. Using Hamilton–Jacob...

Market segmentation has emerged as the primary means by which firms achieve optimal production policy. In this paper, we use market segmentation approach in multi-product inventory system with inventory-level-dependent demand. The objective is to make use of optimal control theory to solve the inventory-production problem and develop an optimal production policy that minimizes the total cost as...

In this chapter we outline the importance of facility location decisions in supply chain design. We begin with a review of classical models including the traditional fixed charge facility location problem. We then summarize more recent research aimed at expanding the context of facility location decisions to incorporate additional features of a supply chain including LTL vehicle routing, invent...

In last decades, mobile factories have been used due to their high production capability, carrying their equipment and covering rough and uneven routes. Nowadays, more companies use mobile factories with the aim of reducing the transportation and manufacturing costs. The mobile factory must travel between the suppliers, visit all of them in each time period and return to the initial location of...
