A shop floor consists of three machines and produces three types of products. Three machines are processing each type of part downstream. The machine processing time is 5 minutes and parts arrives at the shop floor each in 2 minutes. Currently an operator is involved in transferring the product from the source to inventory area while the other operator is carrying items from inventory area to the three machines. The shop floor manager in order to increase throughput decided to simulate the shop floor and experiment with multiple operators and find out the optimum number of operators for throughput of 8 hour shift. Find, 1.1 Throughput of shop floor in 8hr. 1.2 Effect on output if there are 3 operators involved in transferring the product. 1.3 Optimum number of Material flow
