Question
Problem 5-15 The following diagram describes a process that consists of eight separate operations, with sequential relationships and capacities (units per hour) as shown. 10/hr 20/hr 3 15/hr 34hr 30/hr 12/hr 5hr 4 8/hr a. What is the current capacity of the entire process? Capacity 10 units per hour b-1. If you could increase the capacity of only two operations through process improvement efforts, which two operations would you select, how much additional capacity would you strive for in each of those operations? (Enter your answers as whole numbers. Enter the lower operation number in the TOP answer box and the higher operation number in the BOTTOM answer box.) Additional capacity Click to select Click to select b-2. What would the resulting capacity of the entire process be? Resulting capacity units per hourExplanation / Answer
#1, 2, 3 which are the top and #4, 5, 6 which are bottom branch operate in parallel.
The top branch has a throughput of 10/hr and the bottom has a throughput of 5/hr.
These combine and feed into operation #7 which has the capacity to handle both branches as does the final step
The total throughput is the 10/hr plus 5/hr = 15/hr
The maximum throughput would be achieved by improving #1 and #2, bring them both up to 20/hr, which gives an overall throughput of 25/hr
