Assignment:
Layout - Load distance analysis
The Los Angeles plant of Computer Products Corporation will soon add a new wing to its present building to manufacture electronic assemblies. The plant's management is considering two alternative layouts as follows:
The plant's electronic assemblies, the trips that batches of electronic assemblies make between departments, and the distances between departments are shown below:
