Textbook Question
Chapter 5, Problem 17P
Refer back to Problem 16. Suppose that in addition to the usual precedence constraints, there are two zoning constraints within the trim line. First, work elements K and L should be assigned to the same station; both use a common component, and assigning them to the same station conserves storage space. Second, work elements H and J cannot be performed at the same station.
- Using trial and error, balance the line as best you can.
- What is the efficiency of your solution?

A process improvement team is working to improve the production output at the Johnson Manufacturing plant’sHeader Cell that manufactures a key component, headers, used in commercial air conditioners. A header is partof the circulatory system of a commercial air conditioner that moves coolant between various components suchas the evaporator coil and the condenser coil. Currently, the header production cell is scheduled separately fromthe main work in the plant. Often, individual headers are not sequenced to match the product they go into on thefinal assembly line in a timely fashion, and so the product can sit in queue waiting for a header
An assembly line consists of 5 work stations. In order to assemble a complete finished product, the work has to proceed from Work Station 1, to Work Station 2, to Work Station 3, to Work Station 4, then finally to Work Station 5. The output from Work Station 5 is the finished product. The shop floor supervisor sees that unnecessary inventory is accumulating between Work Stations 3 and 4. This inventory is best called:
The trim line at PW is a small subassembly line that, along with other such lines, feeds into
the final chassis line. The entire assembly line, which consists of more than 900
workstations, is to make PW's new E cars. The trim line itself involves only 13 work
elements and must handle 20 cars per hour. Work-element data are as follows:

All of the warehouses are fully automated: packaging is performed by robots on top of electric conveyors. Although the company has saved a lot in labor costs by the use of this packaging line, it has resulted in some excessive waste of material. After some analysis of this waste issue, the company has discovered that the number of product types that are assigned to the packaging line is strongly correlated with the amount of wasted material. Based on this insight, their operations manager has built a mathematical expression that estimates the expected amount of waste from the packaging line as a function of the number of product types in it. The expression is as follows: W = (n-93)2 – (n-88) + 227 In this expression, n is the number of product types you are packing on the line and W is the hourly waste of packaging material (in lbs).
