How many units have to flow through the third step

Assignment Help Operation Management
Reference no: EM132728822

Consider the following four step assembly operation with quality problems.

All resources are staffed with one operator.

-The first resource has a processing time of 4 minutes per unit

-The second resource has a processing time of 3 minutes per unit. This process suffers from a high yield loss and 50% of all products have to be scrapped after this step.

-The third resource also suffers from quality problems. However, instead of scrapping the product, the third resource reworks it. The processing time at the third resource is 5 minutes per unit. In the 30% of the products in which the product needs to be reworked, this extends to a total (initial processing time plus rework) processing time of 10 minutes per unit. Rework always leads to a non-defective unit.

-No quality problems exist at the first and final resource. The processing time is 2 minutes per unit.

-For every unit of demand, how many units have to flow through the third step in the process?

-Where in the process is the bottleneck?

-What is the process capacity?
