Abstract

Selecting a reasonable bidding price and determining the ability to win the bidding process are vital issues for contractors. It is a very difficult problem because there are diversity and complexity in bidding activities. Previous studies only relied on historical data to make decisions; however, the historical data is only one factor affecting the decision to participate in the bidding process. This study uses bayesian belief networks (BBNs) and game theory to determine the likelihood of winning a bid in competitive bidding. To achieve the above objectives, research has conducted to collect data and analyze to identify influencing factors that can be assessed for contractors and competitors will be more inclined to choose bid prices. At the same time, the model also assesses the bidder's interaction with potential competitors to determine a reasonable bid price, as well as the greatest probability of winning.
