Question

(Process Analysis with Multiple How Units) Consider a process consisting of five resources that arc operated eight hours per day. Tlic process works on three different products, A, B. and C: Demand for the three different products is as follows: product A, 40 units per day; product B, 50 units per day; and product C, 60 units per day. What is the bottleneck? What is the flow rate for each flow unit assuming that demand must be served in the mix described above (i.e., for every four units of A, there are five units of B and six units of C)? indicates that the solution is at the end of the book)

Explanation / Answer

Answer:

Step-1The bottleneck in a process with multiple flow units is the implied utilization.

Step-2 Determine available capacity of each resource.(in minutes of work)

Available capacity = available minutes per hour = number of workers x 60 min per hour

Step-3 determine requested capacity demand

requested capacity = demand(units per hour) x activity time (min per unit)

Step-4 determine implied utilization.

Answer: Resource number of workers Processing time-A Processing time-B Processing time-C Available capacity implied utilization 1 2 288000 360000 432000 120 9000 2 2 172800 288000 432000 120 7440 3 1 864000 0 0 60 14400 4 1 0 216000 259200 60 7920 5 2 345600 432000 518400 120 10800 bottle neck is in resource -2 level
