Generating software development environments from the description of product relations

A method is described for constructing software development support system from the description of software product relations. Logical structures of the products have ben expressed by a tree structure. Each product appearing through the software development corresponds to a leaf in a tree and a set of those products and other sets correspond to an internal node. Various kinds of software development are easily expressed by changing the products at the leaves. The description of product relation is translated into a script of process description language (PDL). A support system is obtained by executing the translated PDL script with the PDL interpreter which the authors have developed
