| With the influence of economic globalization, the fierce market competition, thevigorous bidding system, owner dominance, the contractor have to offer the bid price close toor even below the cost without thinking too much about the risk to bid. The profit is thefundamental business survival, so the contractor shall fight for efficiency to develop. Claim isone of project management tools to increase efficiency.Therefore, the paper combined withdomestic and foreign construction companies claim the status quo, by referencing theory andpractice of engineering claims at home and abroad, using system engineering theory, fuzzytheory and Web application layer services, discussing the contractor claim, to providereference and advice for contractor claim to be more reasonable, effective and a highersuccess rate.1)From analysis to then analyze the cognitive line and claims opportunities and itsanalysis of fuzzy discussed based on fuzzy theory claims opportunity analysis, synthesis andrecognition of the basic model.2)The articles proposed the establishment of the project claim case base to solve theproblem of claims management and lack of experience. Elaborated by the claims case basesystem, functional analysis, system partitioning and implementation of the actualprogramming of the latter part of the case base to provide a theoretical framework andprogramming instructions.3)System analysis, claims management and management information systems from aholistic, systematic and dynamic aspects into account, as well as the entire project objectivesconsidered together, establish a valid connection between the cross-disciplinary mechanism,so that the claims managementThe system is more practical value. |
