3 .( 6 pts ) Steps identified byby the same letter are part of the same operation . For instance , in ( a ) , operationA has three FIES , each with a cycle time of 2 minutes per customer . For utilization calculations , assumethat the demand rateat $ 1 customer everyer / minutes is the same for each operation. every operation hasthe same throughput = process throughput ( 1 .e . operations are not just piling up inventory ) .a ) ( 3 pts ) What is the bottleneck , process cycle time , process calcapacity , and lead time ( assuming theprocess is empty ) for the process below ? What is the throughput and average labor utilization for*the process flow diagram shown below if customers arrive every 4 minutes ? ( Hint : Whencalculating cycle times , capacitcities , and labor utilization , pay attention to the number of FIESdoing the same task ; the average utilization is the average of each clerk’s utilization ]A6 min / cust*EAB6 min / custHIGH-AD2 min / cust3 min / cust*4 min / cust6 min / custEA2 min / cust6 min / cust
