PLS ANSWER ASAP AND I WILL RATE A THUMBS UP

Hall, a computer parts company, manufactures computer motherboards using an assembly line that consists of two workstations. The first station has two parallel machines. The process times for both machines are exponentially distributed with a mean of 1 hour. The second station has a single machine whose processing times average 20 minutes. The variance of the processing times at Station 2 is 0.09 hour? We are controlling this production line with the ConWIP policy. The WIP cap for the system is 20 motherboards. The line works 8 hours daily. A. [5 marks] Calculate the throughput of the line assuming PWC performance. B. [10 marks] If you were to control the same line with a push policy such that the same throughput is used, what would be the average WIP in the line? Assume exponential arrivals. C. [5 marks] Given the profit for each motherboard is 5 KD and the holding cost of keeping a motherboard in the line for a day is 0.2 KD. How much would Hall profit in 5 working days as a pull system and as a push system? E. [5 marks] Comment on the results above
