Description
Abstract:	This dissertation presents a new discrete/continuous digital simulation language. GEMS-D/C, a Generalized Manufacturing Simulator, is designed to assist system analysts investigating complex manufacturing systems with a minimum of programming difficulty. GEMS-D/C is a network-based, data-oriented simulation program written in FORTRAN and is capable of representing and analyzing both discrete and discrete/continuous systems. Systems to be investigated are represented by GEMS-D/C networks composted of specialized boxes, nodes, and arcs. GEMS-D/C network structures can be developed to represent combinations of material flow patterns and manufacturing systems. GEMS-D/C network models can contain stochastic and logical decision points, resource constraints, cost considerations, and complex queueing characteristics. GEMS-D/C can also be utilized to study various types of complex real-world problems such as assembly line balancing, sequencing and scheduling rules, job-shop manufacturing systems, transportation networks, in-process inventories, and systems with limited resources. GEMS-D/C provides users with all the relevant features for systems simulation. This includes structural modeling methodologies, interactive or free-format data input, dynamic space allocation, extensive error checking, automatic time-advance mechanisms, an efficient filing system, automated statistical collection, and organized output reports. This dissertation describes concepts, network notations, the simulation algorithm and applications of GEMS-D/C to several prototype examples. A case study of simulation model for the grain transportation system at the Port of Houston demonstrates a real-world application of GEMS-D/C.
