Previous chapters have outlined the functional aspects of BCAPP. At this point it is the intention of the author to demonstrate the validity of the Boolean approach to planning, as well as discussing some outstanding problems. A few examples have been chosen to illustrate the method in general. The first examples will be simple machined parts. These are selected as a simple introduction to the results. After these a plan will be presented for a desk toy, in the form of a scaled up ‘clothes pin’. This is customized with an advertisement, and can be used to hold a stack of paper. Finally, a novel application will be displayed by using the planner to select electrical components for a digital circuit.
