Warehouse synergy : a case study in PTT

Abstract

At present, the case study companies operate their warehouses independently and also face with the low utilization of capacities. The objective of this thesis is to find the way to improve benefits in the case study companies. After analyzing through the choices of improvement in warehousing area, the most suitable option for the case study companies is to phase out some of the existing warehouses. Therefore, the criteria and the screening process used for evaluate the warehouses must be specified and so called warehouse phasing out process. The warehouse phasing out has been developed based on the academic knowledge and the case study companies data in order to create the feasible solution. There are five main steps in phasing out process which are listed as follows: policy and constraint screening, performance and cost evaluation, phasing out alternatives development, capacity feasibility evaluation, and final analysis of chosen alternative. After implementing the proposed process, the best alternative has been selected since it gives the best benefits to the case study companies. The operation costs can be reduced around 100 million Baht per year after implementing. This result has already validated from the case study company.
