In order to determined the optimum combination of manufacturing process in red roof tiles factory, the manufacturing system of red roof tiles in each production were simulated by setting the model of red tiles factory resembling with actual factory. By applying two production types for three kinds of demand pattern, the optimum combination of productions were determined for obtaining the maximum profit. (1) On the case of constant production type when the minimum inventory become less than the setting inventory, the four factors of the existence of mold exchange, leading time, amount of production and demand pattern were specified as significant factors by analysis of variance of total profits and F test. (2) On the case of same period production type of assigned amount production according to the ratio between quantity of leaving stock and inventory at the time of checking the stock regularly, two factors of the existence of mold exchange and the demand pattern were determined as significant factor by analysis of variance of total profits and F test. (3) From the comparison between constant production type and same period production type, two factors of the existence of mold exchange and the demand pattern were recognized as significant factors commonly.
