[4 Points] For the same problem as 4a above fill up the table below and answer the following questions: a. Which configuration has the lowest Ls? a. ? b. Which configuration has the lowest Ws? Mechanics in Crew = / =N/ Is=2 Mechanic Cost ($100/Mec hanic) L- Cost of Total System Robots Cost Per day out of Service c. Which configuration has the lowest War d. Which configuration has the lowest Total Cost (please refer question 4)? 1 e. What would be your recommendations on which system to use? Explain your answer clearly and precisely. 2 System Ls Ls Ws = 2 1 Wq=Ws- = =WS- LL Single Queue with Team Service Case 2: Assume Robots are divided equally among mechanics who work alone (Multiple Queue with multiple servers): (M/M/1 with 2 service rate) Multiple Queue and Multiple Servers p=N/ Number of Mechanics Mechanic Cost ($100/Me chanic) Ls =- u-i Cost of Total System Robots Cost Per day out of Service 1 (M/M/1, M/M/1 with /M, M/1 arrival rate = 1/2) Single Queue with Multiple Servers (M/M/2) 2 Case 3: Assume two mechanics work alone from a single queue (Single Queue with multiple servers M/M/2 system): = U= pa (Formula) = Ls = (Formula) Total Cost/day 4a (3 Points).
