In this exercise (inspired by Nahmias, 2013) the issue of reducing the number of different components  in assembly production is considered.


This issue is very relevant in methods such as Product Modularity, Design for Assembly, Design for Assembly and Manufacture (see Ulrich, 1991, Gershenson and Prasad 1997Boothroyd, 1980 and 2002)

Basic Idea is to increase the possibility to use the same component in different Assembled Models. In this manner it is possible to keep an high number of assembled models (high product diversification) while reducing the inventories levels.

In the following a very simple case is considered with a PC that is assembled from only 3 components: the processor, the hard disk and the memory.
