A hierarchical, modular simulation environment for flexible manufacturing system modeling.

Cho, Tae Ho. January 1993 (has links)
Computer simulation is one of the most widely used techniques in manufacturing systems study. The value of simulation increases constantly due to improvements in computing power. However models of large-scale systems tend to be very complex, and writing simulation programs to execute them can be an arduous task. Rapid modeling of such systems can play a significant role in the selecting manufacturing strategy. This dissertation deals with the design and implementation of tools that aid in such modeling activity by identifying some of the problems that occur frequently in the modeling of flexible manufacturing systems (FMS). This set of tools, collectively called the hierarchical modular modeling environment (HMME), is designed and implement by extending DEVS(Discrete EVent System Specification)-Scheme. The problems identified are in the field of model interconnections, embedding expert systems in models, model structuring and simulation display. An example, of operation overlapping strategy in a hierarchical FMS, demonstrates the utility of the environment. Although developed for FMS simulation, this modeling aid is applicable to many other domains of knowledge-based systems and intelligent control.

Influence allocation methods in group support systems.

Balthazard, Pierre Andre. January 1993 (has links)
The group decision making literature defines three methods of decision making used by and within groups: consensus, negotiation, and voting. Group support systems (GSS) research, with the creation of its enabling technologies, has focused on issues that support consensus-building and negotiation, thus relegating voting to the relatively limited role of prioritization. Surprisingly, the technology of aggregating opinions in GSS has received little research attention, and the procedures for it that have been implemented in even the most sophisticated groupware systems are relatively unsophisticated. Influence allocation processes (IAP) are voting and opinion aggregating methods that allow members to distribute some or all of their decision making influence to others in the group in order to exploit not only the group's knowledge of the alternatives, but its knowledge of itself. Only with the common use of GSS has their use become practical. Two families of influence allocation processes are reconsidered and expanded in this dissertation: SPAN, introduced by MacKinnon (1966a) and a technique based on a proposal by Morris DeGroot (1974) called Rational Consensus by Lehrer and Wagner (1981), who developed it and explicated it as a normative standard for combining opinion. This dissertation first considers the development and implementation of a set of IAP voting tools within GroupSystemsᵀᴹ. Second, a series of empirical studies is used to show how decision groups use voting tools for the selection of a correct solution. Third, simulation studies are used to develop guidelines for the allocation of influence in an alternative forced-choice problem. Finally, a case study of a real group using IAP for an authentic decisional problem is described. Influence allocation processes help reconcile differences in opinion, knowledge, and judgment. As such, they show much potential for improving the efficiency and effectiveness of group decision-making.
