Four Stage Process One Worker Assigned Stage Activity Time Minute Unit Stage Activity Time Q34291376

Four stage process

One worker is assigned to each stage. The activity time (in[minute/unit]) for each stage is:

Activity time per unit (sec)

A : 3

B ; 2.5

C: 4

D: 1.5

(a) Which stage is the bottleneck? What is the process capacityin [units/min]?

(b) Suppose the steps in activity C are made easier, so theactivity time per unit in step D is reduced by 60% (to 1.6[min/unit]). By how much does the capacity of the entire processincrease in [units/min]?

Expert Answer

a) Bottleneck activity is one with highest activity time = C

The capacity of process will be same as capacity of bottleneckactivity = 60/Activity time of C
