QUESTION 1

A product requires four steps, A ->B - >C -> D. One worker is assigned to each step and the activity time for these steps are 9 min, 15 min, 18 min and 10 min, respectively. . Each worker works for 450 minutes/day. Assume steady state.

The capacities of steps A, B, C, D are respectively:

QUESTION 2

Suppose two additional workers are added, one to step B and other to step C. What is the capacity of the process?

QUESTION 3

Suppose two additional workers are added, one to step B and other to step C. The process is producing 40 units/day. What is the labor utilization?

QUESTION 4

Suppose there are four steps in series with capacities 20, 25, 14, and 45 units/day. What is the capacity of the whole process?

Explanation / Answer

Ans 1- capacity = Total time / time per task

Capacity of A= 450/9 =50 tasks

Capacity of B= 450/15 =30 tasks

Capacity of C= 450/18 = 25 tasks

Capacity of D = 450/10 =45 tasks

Ans2

New capacity at B = 30x2 =60

New capacity at C = 25x2 =50 tasks

Capacities of A and D remain same.

Process capacity is equal to lowest step capacity i.e. Capacity at D- 45 units

Ans3 -

Labor utilisation = output / max. Output possible

= 40 / 45 = 88.88%

Ans 4- Process capacity is equal to the capacity of the slowest step. In this case it is 14 per day.
