Abstract

The Inventory Routing Problem (IRP) is a problem that can be found in distributing goods. It considers the two important aspect such as inventory management and vehicle routing processes. This paper addresses the IRP multi-period, multi-product, and multi-supplier with capacitated homogenous fleet that housed at depot. Products are transport from supplier to assembly plant in finite horizon. The objective of this study is to minimize inventory and travel cost in distribution processes. A two stage algorithm is proposed. In the first stage, the initial solution is obtained using the least cost insertion algorithm. The results are improved in the second stage with a record-to-record travel algorithm that employ the 1-0 and 2-Opt local search. The algorithm is tested using the data sets from the literature and the data is processed using the software program that has been built. The results obtained are good compare to previous research, and the proposed algorithm produce short computational time.
