This paper further develops some of the ideas set out by Cheng (1998) for output analysis using Bayesian Markov Chain Monte Carlo (MCMC) techniques, when a regression metamodel is to be fitted to simulation output. The particular situation addressed by Cheng was where there is uncertainty about the number of parameters needed to specify a model. This arises(More)
An approach using semantic metrics to provide insight into software quality early in the design phase of software development by automatically analysing natural language (NL) design specifications for object-oriented systems is presented. Semantic metrics are based on the meaning of software within the problem domain. In this paper, we extend semantic(More)
This paper presents an overview of a simulation environment used for rapid modeling of electronics manufacturing lines. This environment, the Electronics Manufacturing Simulator (EMS), consists of a line definer and a static analyzer. Included in this paper are a description of the EMS, an application of the EMS, and a discussion of results of the(More)
Simulation experiments can benefit from proper planning and design, which can often increase the precision of estimates and strengthen confidence in conclusions drawn from the simulations. While simulation experiments are broadly similar to any statistical experiment, there are a number of differences. In particular, it is often possible to exploit the(More)
Engineering education in the United States underwent a signitlcant change in the early 1950’s. According to an article in ASEE Prism, “the post-World War II curriculum model, heavy on math and science and relatively light on engineering design, comes in for its share of reproof.” (Hubband, 1993). The reduction in design courses was accompanied by a similar(More)
This paper describes the research efforts in the Center for Computer Integrated Manufacturing at the Oklahoma State University to develop an object-oriented modeling environment. After providing the underlying motivation for the research effort, some of the major research tasks are described. Highlights of this development effort are: physical and(More)
