Computer-aided process planning (CAPP) is an essential component in linking computer-aided design (CAD) and computer-aided manufacturing (CAM). Operation sequencing in CAPP is an essential activity. Each sequence of production operations which is produced in a process plan cannot be the best possible sequence every time in a changing production environment. As the complexity of the product incr...

Today exchange of data among CAD systems becomes more important. As each CAD system has its own flavor to represent the same objects, exchange of data among them is full of issues. Most common problems are incomplete transfer of presentation information, associativity between representation and presentation, usage of annotation planes and text. They are analyzed in details and possible solution...

Logic( -based) programming languages are today the center of very many research efforts. One of these languages, PROLOG (PROgramming in LOGic), is used to program expert systems, natural language processors, computer aided design systems and compilers. A parallel variant of PROLOG is suggested as the language of the Japanese Fifth Generation computer project. Parallel to these efforts, a class ...
