碩士 === 國立交通大學 === 土木工程系 === 89 === The survival of a construction contractor depends on continuous flow of awarded projects. To obtain projects, the contractor is required to search project opportunities on a daily basis and bid on suitable projects. Recently because of the widespread use of computers and internet, more and more bid invitations including public work project are announced on the internet. Because of the easy access to digitalized business opportunities, the amount of bid invitation information for the contractor for review each day is increased. However, limited by the available resource and time, the contractor must decide the level of effort he wants to be devoted to for each invitation. The decision of bidding includes the level of effort the contractor to devote in the bidding process, and the bidding price. Many bidding models have been developed. However, most of them focus on the determination of the optimal bidding price. Few dealt with the issue of determining the optimal level of effort the contractor should be devoted to, which require the consideration of many qualitative and fuzzy variables instead of quantitative variables as in the traditional bidding models. The proposed research will focus on the analysis of variables that may be considered to determine the level of effort under a uncertain competitive environment. We expect the model be able to explain questions such as why a contractor roughly estimated one project but estimate another project in a great detail; and why he gave up the bidding opportunity after an on-site visit or query about the project owner.
