Study On Multi-objective Decision Evaluation Of Certificate A Office Intellectualization

Certificate A office intellectualization system technology is combined with the communication and the information technology, the computer network technology, the modern architecture science and the intelligent control technology. As information technology unceasingly develops, its technique content and the complex degree is also getting higher and higher. Certificate A office intellectualization systems are included building automation system, communication automation system, office automation system, fire automation system and security automation system.Certificate A office intellectualization makes great use of link of building's structure, automation system, the service and management, with system engineering viewpoint to carry on the optimum composition of the above five systems (system integration). The multi-objective decision means that the decision-maker proposes a question, sets up goals, collects material, combines science reasonable multi-objective decision methods to establish a effective system model, carries on the quality synthetic evaluation to the technical economy target, provides the reasonable sorting result for the decision-maker and screens the preferred plan from strategic decision's angle, in order to solve the coordination problem among the economy, technology, environment and society.The paper embarks on a selected topic background and research significance. It unifies the domestic and foreign research present situation, proposes the research technical route and elaborates the design principle, the design standard as well as system's composition, the principle of work on intellectualization systems. The article takes engineering plan of building automation system as a master line and conducts the evaluation study on the various plans' system structure and the technical economy characteristic with many kinds of multi-objective decision methods. Finally the paper obtains plan sorting, at the same time recommends the most superior alternative plan.The article innovation spots are to make analysis on certificate A office building automation system in Chongqing, to use multiple objective decision-making method--TOPSIS and inferior to rank--ELECTREⅠand the ELECTREⅡ. From objective angle, the paper introduces decision preference, progressively analyses alternative plan. Focusing on five kind of well-known brand alternative systems which provides on the designing department, the paper carries on the quota multi-objective decision. The paper unifies the PROMETHEE to research sensitivity, applying the decision Lab 2000 software with GAIA plane analysis weight sensitivity to appraise the influence degree by evaluating indicator data change to decision-making result, thus determine evaluating indicator that affects the sensitivity of the case.Unifying three kind of progressive method overall evaluation decision-maker subjective preference, the decision-maker will select the optimal solution- Simens APOGEE building automation system, Jonson automatic control Metasys building automation system is taken as an alternative plan. Recourse consumption rate and communication speed make great contribution to the optimal solution, the investment of construction cost compared to other factors is the most sensitive factor. Therefore the decision-maker should take strict control of construction cost.
