【摘要】：随着市场经济的深入发展,建设工程造价管理适应市场运行机制的迫切需要,尽快与国际惯例接轨,是摆在广大工程管理者面前的重要任务。我国工程技术人员在长期的工程实践过程中,不断的总结、探索、积累经验、综合分析而形成了全面丰富的工程造价信息,对工程建设项目的投资预算、合理确定计价标准、有效地进行工程费用管理有着极其重要的价值。工程造价管理信息系统可以对有关工程造价各种标准、实际数据、经验进行收集、整理、积累、存储、分析、使用,实现各类造价信息的共享和动态更新,为工程造价管理提供可靠的依据,大大提高效率和管理水平。针对水运工程造价管理信息系统的特点,在系统知识库设计中,应用人工智能领域的案例推理(CBR)方法,用以解决已完工程实际造价信息和专家经验知识在工程概预算和造价控制中的有效利用问题,使水运工程历史资料得到了充分利用,工程造价信息实现了共享和动态更新,专家经验知识得到了科学表达和管理。通过对某地区水运工程造价管理信息系统的需求分析,提出了CBR方法的应用模型。为了使水运工程造价管理的案例数据的应用达到有针对性和有效性的效果,根据不同类型的水运工程的特点,设置了统一的分类代码体系,为案例推理方法的正确应用打下了良好的基础。
[Abstract]:With the further development of market economy, construction cost management meets the urgent need of market operation mechanism, and integrates with international practice as soon as possible. It is an important task in front of the vast number of project managers. In the long process of engineering practice, the engineers and technicians in our country have continuously summed up, explored, accumulated experience, comprehensively analyzed and formed comprehensive and abundant engineering cost information. It is very important for the investment budget of the construction project to reasonably determine the valuation standard and to manage the project cost effectively. The project cost management information system can make use of all kinds of standards and actual data of the project cost. The experiences are collected, collated, accumulated, stored, analyzed, used, and realized the sharing and dynamic updating of all kinds of cost information, which provides reliable basis for engineering cost management and greatly improves efficiency and management level. According to the characteristics of waterway engineering cost management information system, the CBR method in the field of artificial intelligence is applied in the system knowledge base design. In order to solve the problem of effective utilization of actual cost information and expert experience knowledge in engineering budget estimation and cost control, the historical data of waterway transportation projects have been fully utilized, and the engineering cost information has been shared and dynamically updated. The expert experience and knowledge are expressed and managed scientifically. The application model of CBR method is put forward by analyzing the requirements of the cost management information system of a regional waterway project. In order to make the application of case data of waterway project cost management achieve the effect of pertinence and effectiveness, according to the characteristics of different types of waterway engineering, a unified classification code system is set up. It lays a good foundation for the correct application of Case-Based reasoning (CBR).
