Add to ORKGA research effort currently underway at the Naval Postgraduate School deals with the design and implementation of a computer system for translating natural language descriptions of simulation problems into executable computer programs. In this system, English text is translated into an internal data structure, which can be considered to be the computer's "mental image" of a simulation problem. This internal data structure is then translated into a computer program which will perform the simulation. This thesis reports on the design of an appropriate internal data structure for conveniently representing simple queueing problems and on the development of a procedure for translating such a data structure into a GPSS program. Also, p...
