Each unit needs processing on both stations. Zero Inventory RM FG [3, 9] [3, 9] The processing time for a unit at a station is uncertain and the range is 3 to 9 minutes per unit. The average time is 6 minutes per unit. The rules for running the process are as follows: (1) Infinite supply of raw materials (RM), (2) WS2 moves a unit to finished goods (FG) as soon as its processing on WS2 is complete, (3) WS1 moves a unit to WS2 when its processing on WS1 is complete and also WS2 is empty, and (4) WS1 starts working on a new unit as soon as WS1 is empty. The simulation run of the line for 600 minutes (10 hours) has the following results: 1. The output in 600 minutes is 86 units (or, 8.6 units per hour). 2. The average amount of time a unit spends on WS1 is 6.97 minutes. 3. The average amount of time a unit spends on WS2 is 6 minutes. 4. Station WS1 always has a unit (either completed or blocked). So, the average inventory on WS1 is 1 unit. 5. Station WS2 has a unit only when it is working
