An Automated Database System for Construction Bidding
A number of probability-based bidding models have been developed to assist a contractor in preparing bids that improve chances of winning over the competition. Models based on utility...
Adaptive, Multi-Resolution Modeling of Construction Plans
The process of developing a construction plan is complex, taking many considerations and constraints into account. In contrast, the CPM paradigm of planning allows only the results of...
Tutorial: Fuzzy Expert Systems
This extended abstract presents a brief introduction to a tutorial on fuzzy expert systems. The precepts of set theory and classical predicate logic are briefly reviewed to provide a foundation...
Design Information Hierarchy for Construction Method Selection Process
The Construction Project Planning (CPP) stage is a critical stage for the success of a construction project. This stage lays the framework upon which most of the construction decisions...
