Adhesive Selection by Means of the PAL Program

Source

The development of PAL, a material selection program, is reviewed in relation to the correct choice of an engineering adhesive. For this choice to be accurate the requirements of the adherends, the productions processes and the ultimate use of the bonded components need to be taken into account. It is shown that selection by means of a “rejection-residue” process is an effective basis on which to construct an “Expert System” and that quantitative, and frequently elusive, information does not have to be used. PAL's own form of “fuzzy-logic”, which is illustrated, copes well with imprecision and allows extremely fast operation. This latter is one of PAL's challenges of the conventional approach to the subject which usually comprises a “Shell” developed in isolation from the information (expertise) with which it is subsequently loaded. The modus operandi of PAL is described together with its automatic presentation of important, though unsolicited, information.
