Knowledge acquisition and development for formwork selection system

Article Abstract:

A formwork system is designed to support newly-poured concrete together with the mold and the necessary bracing. It constitutes a big part of the cost of any project and cost reduction can be attained by selecting the right formwork. Choosing the correct formwork requires extensive experience and is usually done by a senior engineer. To assist in the selection of the formwork, an expert system is developed. These are two-stand alone units, one for the vertical formwork named Wallform and the other for the horizontal formwork named Slabform. The EXSYS Professional shell was used in writing the expert system.

SuperChange: expert system for analysis of change claims

Article Abstract:

Site engineers sometimes have to make legal judgments that can lead to costly claims and litigation. While low-cost legal advice may help reduce such risk, the real world does not afford this recourse. A progress report is presented on the development of an expert system program to aid and train tyro field engineers in evaluating legal consequences arising from contract disputes. The logic of SuperChange, which is patterned after Federal Acquisition Regulations language,makes it compatible with government construction projects. It is claimed that the system can help improve decisions of field engineers.

Expert system for equipment selection for earth-moving operations

Article Abstract:

Choosing bulldozers, scrapers, loaders, haulers and compactors is a crucial task in keeping construction within budget and schedule requirements. To assistcontractors in deciding properly what earthmoving equipment to use, an expert system is designed using the VP-Expert development package. Acquisition of knowledge from human experts and other references is among the most important aspects in the development of the expert system. Though there are limitations in the expert system developed, testing shows that its application is feasible.
