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...
The inventory level shown in the Information System contrary to popular belief and assumptions in most academic papers and in spite of the considerable amounts invested in information technology, is often inaccurate. The inventory inaccuracy occurs when the inventory shown in the Information System is not in agreement with the actually available inventory. In this paper, we first describe the m...
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 ...
This paper aims to design an inventory model for a retail enterprise with profit maximization objective using the opportunity price discount facility given by supplier. In objective, demand should be increased. The can boosted lowering selling price. However, may not always give best profit. Impreciseness plays vital role during such decision-making. decision-making and managerial activities im...
Study on the Inventory Routing Problem of Refined Oil Distribution Based on Working Time Equilibrium
the real world is full of uncertainties and parameters such as demand cannot be determined exactly. in this case, using crisp (exact) values and statistical methods due to absence of sufficient information, seems unwise. so in this paper, an approach is presented for using fuzzy numbers in continues review policy related decision-making. in this supply chain, there are two enterprises, a and b ...
