Abstract
Abstract : A system, called MATHMODEL was developed by X. Ge in his research at the University of Pennsylvania. It is a very complex and large multi-phase system. It consists of 142 modules and 60,000 lines of PL/1 code. MATHMODEL is based on an old (1984) version of MODEL system, which automatically translates equational specifications into highly efficient programs in PL/1. Computer Command and Control Company (CCCC) has a much more advanced and reliable version of MODEL that generates programs in several languages (PL/1, C and Ada) and that runs on several computers (IBM and Digital). It also generates programs that can be executed in parallel on distributed computers. Most important, CCCC's MODEL contains many more operations useful in mathematical modelling (e.g. matrix algebra, relational algebra, etc.) This version is much more reliable and robust and is well documented. The project has merged MATHMODEL's capabilities with those of CCCC's MODEL and has transformed MATHMODEL into a greatly more effective tool for mathematical modelling than any system developed to date.
