Consider a production process consisting of three resources:

RESOURCES/ PROCESSING TIME (MIN/UNIT) / NUMBERS OF WORKERS

1. (LATHE) - 10 -2

2.(DRILL) - 6-1

3.(WELD) - 16-3

ASSUME THERE IS SUFFICIENT INPUT TO THE PROCESS:

2A. WHAT IS THE CAPACITY OF EACH RESOURCE IN UNITS/HOURS?

60/10*2 = 12 UNITS PER HOUR/ 60/6*1 = 10 UNITS PER HOUR/ 60/16*3 = 11.25 UNITS PER HOUR

2B. WHICH RESOURCE IS THE BOTTLENECK?

RESOURCE 2 IS THE BOTTLENECK AND THE PROCESS CAPACITY IS 10 UNITS PER HOUR

2C. WHAT IS THE FLOW RATE IF THE DEMAND IS 15 UNITS PER HOUR? THERE IS SUFFICIENT INPUT FOR THE PROCESS. (FLOW RATE= MINIMUM(AVAILABLE INPUT, DEMAND RATE, PROCESS CAPACITY)

2D.WHAT IS THE UTILIZATION OF EACH RESOURCE IF DEMAND IS 15 UNITS PER HOUR? RESOURCE UTILIZATION =FLOW RATE / RESOURCE CAPACITY

2E. GIVEN THAT THE DEMAND IS 15 UNITS PER HOUR, WHAT KIND OF PROCESS IS THIS INPUT-CONSTRAINED, DEMAND CONSTRAINED OR CAPACITY CONSTRAINED?

3. IN A CAPACITY-CONSTRAINED PROCESS, WHY ARE WE INTERESTED IN LOCATING THE BOTTLENECK?
