The research into ILRIP for single-stage logistics distribution network under stochastic demand based on JITD

Just in time distribution (JITD) is a mode of distribution in terms of demand-pull replenishment. It can improve the customer service level and reliability of quick response, control inventory risk in the supply chain effectively. This paper applies the JIT theory into distribution network design, coordinates the whole inventory of network, considers the punctuality and stability of distribution, a model of Integrated Location Routing and Inventory Problem (ILRIP) is built on the condition that the demand is Stochastic and there are many distributions and customers from the perspective of integrated logistics, then a bi-level algorithm of Particle Swarm Optimization (PSO) is designed to solve it. At the end of this paper, a numerical example is given. The conclusion will help to optimize the distribution network of supply chain, which can improve the reliability of quick response and the customer service level, as well as reduce cost.
