Problem 2 Consider a production line with four stations. Station 1 can produce 15 units per hour. Station 2 has three identical machines. Each of which can produce 12 units per hour (each unit only needs to be processed on one of the three machines). Station 3 can produce 6 units per hour and finally Station 4 can produce 10 units per hour. The below figure illustrates the production line. Based on the above, answer the following a) Which Station is the bottleneck station? And what is the system process time? b) What is the production capacity per shift (8 hours) if you know that the plant manager decided to allocate one and half hours for cleaning every shift? c) How the production capacity will change if one machine (which is identical to that of Station 3) was added to the Station 3(e.g Station 3 will have 2 identical machines)
