Question
Consider a process consisting of five resources that are operated eight hours per day. The 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
Demand
Product A: 40 units per day= 5 units per hours
Product B: 50 units per day= 6.25 units per hour
Product C: 60 units per day= 7.5 units per hour
Capacity= number of workers (60)
Total workload
processing time for A * Hourly demand for A
processing time for B * Hourly demand for B
processing time for C* Hourly demand for C
Implied Utilization = Total workload per capacity
The bottleneck is when implied utilization is 1
Resource Capacity Total Workload Implied Utilization 1 120 5*5+5*6.25+5*7.5=93.75 78.125% 2 120 82.5 68.75% 3 60 60 1 4 60 41.25 68.75% 5 120 97.5 81.25%
