Pаrt II (50 pts tоtаl) In this pаrt, yоu can write yоur answers on the paper. At the end of exam, please scan your solution and upload through the "Final Exam File Upload" Assignment. Your written work must be sufficient to show how you obtained your answer. (___,____,____,____) a. Consider the following warehouse with square storage grids numbered 1 through 20. All pallets enter through port 1 (SW corner, gird id#1). 40% of the pallets depart through port 2 (SE corner, grid#4 ) and 60% use port 3 (NW corner, grid#13). Two product types are stored. Product type 1 requires 4 grids and product type 2 requires 16. Total product throughput is 20 pallets per day for product type 1 and 40 pallets per day for product type 2. Each grid is 1 x 1. In which grids should you store product type 1? (Note: You must show your computations for at least one grid location).

Each machine fails on average after 6 hours of use and repair times average 1 hour. Find the probability the repair person is busy with a repair but there are no other down machines waiting for repair. (10 pts) ____________ c. Consider a service system with two parallel servers and exponential service time averaging 20 minutes. The arrival process is Poisson with rate 5 per hour. When service is available without waiting, all arrivals enter the system. When both servers are busy but no one is waiting one-half of arriving customers enter the system (the others balk and go elsewhere). When there is at least one customer waiting all arriving customers balk. Find the probability an arbitrary arriving customer will enter the system instead of balking. (10 pts) ____________________. d. Five different drink mixes are bottled on the same line. Changeover times are shown in the table below. A production engineer is trying to decide in which order to bottle the drinks. Assuming a partial order of B->A->C has already been constructed, use the closest insertion heuristic to decide the next step, i.e. which drink mix is added next to the sequence and where is it placed?
