Consider the following process. The processing time (sec/unit) is given for each worker. a) Calculate the following design parameters for this process: b) Customers arrive at this process in the following way: Every 240 secs two customers artives at M1 starting from time 0 and every 240 secs one customer arrives starting from time 100. Once a customer arrives at stage 2 , if both servers are empty, the customer is served at the server with lower processing time. Fill in the below Gantt chart. Each grid in the following chart represents 20 sec. You can extend the below chart as needed. c) Under the arrival schedule given in (b), calculate the following run-time parameters: d) Use the total WIP and the flow time calculated in (c), then apply the Little's formula to get the flow rate and the actual CT. Specifically, show that a. The flow rate calculated using the Little's law is the same as the flow rate calculated in (c) using the Gantt chart. b. The actual CT calculated using the Little's law is the same as the actual CT calculated in (c) using the Gantt chart
