Week 3 Assignment
You are to prepare answers to the following based on the information in the text. Throughout this course, the primary source of information to answer homework questions should be the textbook. Cases are valued at 25 points each and questions/problems are valued at 5 points each.
Chapter 6: Toshiba’s Notebook Computer Assembly Line (page 199). Answer all six questions in the textbook.
The line operates for 7.5 hours per day. Workstation 9 is the bottleneck in the initial line balance, limiting the cycle time to 2 minutes, so output is limited to 30 units/ hours * 7.5 hours = 225 units per day.
All current stations are under that cycle time except for station 6 (position 9). Because of the precedence relationships for tasks 16 and 17, they must be split across two stations to meet the new cycle time. A simple way to meet this cycle time is to just put task 17 into position 10 and add an additional worker. The efficiency of this solution is:
With the original design, output is 30 units per hour. To reach output of 300 units would require 2.5 hours of overtime per day.
This may be possible with a redesigned line, but we might not have enough Line Positions to accommodate the new design.
