An industrially-motivated knowledge-based environment for modelling and simulation (KEMS)

The manner in which the software components are integrated into the knowledge-based modelling environment KEMS is referred to as `medium coupling´. This is unlike `loose coupling´ which uses simple file transfers between modules, and `tight coupling´ which uses a single language for implementation. KEMS runs on PC 286 and 386 systems under MS DOS. An important reason for targetting onto these machines is the desire to make simulation tools available to a range of users at widely differing sites. The concepts within the prototype software are being evaluated using process models for gas distribution and control supplied by British Gas. The knowledge-acquisition front-end is being used to increase the model repertoire, and is itself being evaluated for use by engineers. Further knowledge-based tools which are to be added include an expert system adviser for simulation (to aid novice users), and model validation aids. The overall aim is to make complex modelling and simulation methodologies accessible to a much wider range of engineers and other users than is currently achievable
