Question:
An assembly-line process has five tasks as listed in the table below:
Task time | |
Task 1 | 10 min |
Task 2 | 10 min |
Task 3 | 10 min |
Task 4 | 25 min |
Task 5 | 5 min |
Three workers (S1, S2, and S3) are staffed on this assembly line, and the assignment of tasks to each worker is:
- S1 does Task 1.
- S2 does Tasks 2 and 3.
- S3 does Tasks 4 and 5.
For the following questions, we assume that process is operating at full capacity.
- Which worker is the bottleneck of the process? What is the process capacity in [units/hour]?
- What is the idle time of each worker in [minutes]?
- Assume a wage rate of $18 per hour. What is the direct labor cost in [$/unit]?
- Still assume a wage rate of $18 per hour. If we reassign Activity 5 from S3 to S1, what will be the new direct labor cost in [$/unit]? Is this reassign an improvement?
