Develop the Er-2/Er-2/1/3 Model 30 points Let the mean arrival and service rates be denoted by and . Part 1: 10 points Do the state-space diagram with mean rates labeled arc's connecting these states. Part 2: 7 points Write the steady-state equations for this system using general rates. Part 3: 5 points Write the matrix equations to solve the probabilities using mean arrival rates as 6 jobs/hour and the mean service rate being 5 jobs/hour. That is, write A and r with the numbers: Ap=r And solve for the probabilities p. Part 4: 8 points Solve for the numerical values of the system performance measures: CT,TH, WIP and U
