Multi-agent In The Construction Budget System

With the computer technology in social production continues to develop the application of construction process of the budget information in the field are constantly toward the deep level. Although the computer technology to a certain, improved the estimate of the budget document the efficiency and accuracy, but still not completely out of the original pen and paper kind of budget model. Its development is not satisfactory; the vast majority of budget estimate is only manual calculation software upgrades, a low degree of automation, the lack of intelligence, still need to invest a lot of manpower and material resources. With the construction of large and growing budget estimate the accuracy of the results of increasingly high demand, the budget problems that exist in the software become more and more prominent. The main problem was concentrated in two areas, first the calculation of the amount of engineering; followed by the preparation of the budget document, the degree of automation。Since 1986, new concept called Agent, Agent and Multi-Agent system has been applied in many fields[1], As the Agent with the reactive, autonomous, goal-oriented and targeted environmental characteristics, etc[2].This estimate budget for the software to solve a problem provides an effective way. In view of the above software applications for the budget of the status quo analysis and the characteristics of the Agent and Multi-Agent Systems in cooperation and consultation [3], solving ability of the research, In this paper, "core-Classes" as the main design ideas, using plug-in approach to build the various functions Agent, completed the "Multi-Agent system design construction budget". This subject is in the design of the two functional Agent, that component identification Agent and budget Agent, the purpose is to solve engineering quantity calculations and budget documentation issues. Agent was first identified in the component-based Dwg electronic drawings of the building components for automatic identification, and then through a simple and uniform approach to reasoning, thinking out of the building in order to estimate the number of required earth. Then the budget Agent Then the budget Agent Component identification according to the results of Agent to automatically take over reasoning charges, fixed and materials database to extract relevant information, and then concludes that the budget document.This paper is divided into six parts:the first part is the background and significance of the research and construction budget for the status of software research at home and abroad. The second part of Agent-related presentations, including single-Agent and Multi-Agent systems and Agent-oriented software engineering research. The third part is related to the concept of the construction budget, including the construction budget and construction drawings, engineering, fixed cost of computing and engineering knowledge. The fourth part is Agent communication mechanism in the construction budget system in the research, including Agent Communication Agent body design and the design of communication primitives. Fifth part is the design and implementation, which is partly the subject of this article, the main architecture of the system design of the overall framework, the system works, the various Agent design, system development related to technology, database design and system part of the code. Six parts is a summary of the main topics of this.
