Jetaway, a small manufacturer of replacement parts for
the aircraft industry, had always maintained a simple
layout—all like machines were located together. That way
the firm could be as flexible as possible in producing
small amounts of the variety of parts its customers re-
quired. No one questioned the production arrangement
until Chris Munnelly started to work for the company.
Chris was actually hired to upgrade Jetaway’s computer
system. In the process of creating a database of part rout-
ings, Chris began to see similarities in the parts pro-
duced. A part routing matrix for nine of the most popular
parts is shown below, along with a schematic of the
factory layout.
Chris, who was already tired of being a programmer,
decided to reorder the matrix and see what he could
find. If he could identify distinct part families, he could
reorganize the placement of machines into the cells he
had been reading about in his business magazines.
Maybe then someone would notice his management
potential.
Help Chris gain status in Jetaway by creating a
cellular layout for the company. Show your results in a
schematic diagram. Be sure to include the reordered
routing matrix.
