Deng, Zhong Ming (1995) Extended state space modelling and influence diagrams for construction processes and aids. PhD thesis, University of New South Wales, Australia.
Abstract
The investigation described in this thesis is concerned with the development and implementation of suitable models for construction operations and management aids. Two aspects of construction problems are discussed in the thesis: (i) One aspect relates to microproblems which need to be solved to determine the desired performance of a system. The thesis starts with an infinite source queueing problem to show the model building process. It then extends the modelling concepts to three more complex queueing problems: the cyclic queue problem; the priority queue problem; and the heterogeneous queue problem. Finally, applications of the modelling methodology in the context of examples from actual field situations are given. (ii) The other aspect relates to macroproblems--problems that deal with strategic considerations. The modelling concepts are extended to the critical path network modelling of construction projects. It is shown that the model can include such factors as uncertainty and rework. The methodologies are also used as a decision tool for the analysis of problems in contract bidding. Influence diagrams and state space methods are used as the modelling methodologies throughout. Influence diagrams are useful in that they help map out the complicated relationships between the elements and they help derive the associated equations. Mathematical models of construction operations and management aids are developed to model the behaviour of the systems or processes and to allow predictions of performance to be made. By iteratively rearranging the model (or changing the structure of the influence diagrams) it is possible to design the system to achieve a required performance. The methodologies used in this thesis are an integrated systematic approach to the modelling, analysis, and implementation of construction operations and management aids. The systematic developments achieved in the thesis provide a comprehensive approach to construction problems. These developments provide extensions to previous modelling techniques and offer valuable insight into the nature of construction problems.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
