Abstract :
The authors describe a two-stage procedure for generating random cutting-tool requirement matrices (part type vs. tool type 0-1 incidence matrices) on the basis of expert opinions about the characteristics of such data. In the first stage, row-sums and column-sums of the tool requirement matrix are sampled from two user-specified multivariate normal distributions subject to the feasibility condition that the row- and column-sums yield the same grand total. In the second stage, the binary values of the matrix elements are determined by means of a heuristic. The resultant matrix reflects the desired characteristics, such as part type similarities and tool usage dependencies
