How to calculate the area of each department is very important. The size and the number of machines; and the adequate area required around them should be determined. Sufficient space for aisles’ width is to be provided in any factory. For main aisle, 12 to 20 ft. in width is required[11,12]. The aisle for human needs to be 2.5 ft. in width while 12 ft. is required for two lift truck to pass each other in the aisle [11,12]. In this paper, 6 ft. space around machines with long height was considered. Finally, the required area for each department was calculated and presented in Table 1.
