In this article, we study an Inventory Routing Problem with deterministic customer demand in a two-tier supply chain. The chain network consists of supplier using single vehicle given capacity to deliver product type multiple customers. We are interested population-based algorithms solve our problem. A Memetic Algorithm (MA) is developed based on the Genetic (GA) and Variable Neighborhood Searc...

in this paper, we introduce a model  to optimization of milk run system that is one of vrp problem with time window and uncertainty in inventory. this approach led to the routes with minimum cost of transportation while satisfying all inventory in a given bounded set of uncertainty .the problem is formulated as a robust optimization problem. since the resulted problem illustrates that grows up ...

With the growing focus on supply chain management, firms realize that inventories across the entire supply chain can be more efficiently managed through greater cooperation and better coordination. This paper presents a comprehensive and up-to-date review of the joint economic lot sizing problem (JELP) and also provides some extensions of this important problem. In particular, a detailed mathem...
