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 required. 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 routings, Chris began to see similarities in the parts produced. 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 routingmatrix.
