| Summary: | This thesis describes an operational research study applying decision theory and quantitative methods to the problems of competitive bidding. The study was provided with data and information by four English building construction companies. First a preliminary feasibility study was conducted which indicated that the potential for substantial benefits exists. Then the decision problem was formulated in a quantitative manner, which allows treatment of the variation due to estimating uncertainty, and of the constraining effect of resources. The Friedman model and some of the published variants were presented and discussed. This led to the development of i General Distribution decision model which incorporates managerial assessment of the competition into a probabilistic framework. This Model, four Friedman variants, and a feedback model were tested with data supplied by the participating companies. The sample was too small for the results to be conclusive but they did indicate that the basic Friedman Model and the General Distribution Model can equal or outperform actual company behaviour. Partial implementation of the General Distribution Model indicated that it may be practicable.
