Unformatted text preview: st model consists of eight measures and 21 dimensions with five defined tolerance-cost couples each. This implies that we have 105 binary variables in our optimization problem. Data about the model has been collected from the CAT software RD&T [RD&T, 2002]. Figure 1: Test model. The test has been divided into two sections: (i) an analysis of how the proposed algorithm fulfils the constraints on the measures, and (ii) a comparison between the suggested algorithm and exhaustive search in terms of computational time and optimal value, of which the latter of course should coincide. Data from the first test is illustrated in Table 2. Eight measures are considered, four in the flush direction and four in the gap direction. Each measure has a number associated with it that corresponds to the arrows in Figure 1. For example, Flush_1 is the size of the flush between the body and the bootlid by arrow 1 in Figure 1. τ_D is the accumulated measure variations/tolerances. V is the upper bound that must not be exceeded. The optimal cost in this very case is 25.1. An Efficient Solution Measures V τ...
