Abstract: Siam Cement Public Company Limited (SCC) faced stiff competition after the economic crisis in 1997, decided to close most of their warehouses for the change of logistics system. SCC presently operates five cement plants located whole regions in Thailand with except of the northeast region where three warehouses are still operated. This plant distribution system can be called the decentralized plant distribution system. Which plant distribution system is more efficient for SCC as the logistics strategy between centralized and decentralized? Based on this background, total logistics costs of both systems are formulated and calculated. In addition, the locations of a single warehouse without plant operation are evaluated using linear programming to minimize total logistics costs, which calculated with and without environmental cost. The results of calculation showed that transportation cost was the most significant cost of the plant distribution system and a decentralized plant distribution system is more efficient.
