Analysis of the mapping and transferring mechanism, and the sensitivity of quality characteristics of Complicated Electromechanical Products (CEP) reveal that the coupling of functionality and structure, and uncertainty in their mapping relations are important factors that influence the quality of CEP. By integrating the principals of Axiomatic Design (AD), this paper proposes a concept of decoupling design for quality characteristics of CEP. A model for decoupling control in the mapping processes of CEP is presented. In the model, formation-process of quality characteristics of CEP is transformed into iterative zigzagging decomposition and mapping between functional-domains. Then mapping matrixes are utilized to facilitate product designers to identify coupled quality characteristics in CEP, and to reduce complexity in function and physical structure and the product development. The model presented is used in the design of the transmission system in the first direct-drive hobbing machine in China, which effectively reduces the complexity of transmission system of hobbing machine and improved gear hobbing accuracy. 相似文献

Development Management (DM) in decision phase, Project Management on behalf of the owner (OPM) in implementation phase and Facility Management (FM) in operation phase are three isolated management tools during traditional life cycle management of construction project. As a result, a lot of potential disadvantages are aroused. In recent years, many research organizations try to reform the traditional method using different integration means. This paper tries to explore into integration of DM, OPM and FM to overcome the malpractice of traditional life cycle management of construction project. The research focuses on three aspects: 1.putting forward the concept of Life Cycle Integrated Management (LCIM), based on management integration theory; 2. Raising a new idea to owner's (operator's) management organization design, which emphasizes on the balance of life cycle objectives; 3. Analyzing an information module, level and method of system integration of Life Cycle Integrated Management Information System. 相似文献

Abstract: Stakeholders are an integral part of environmental conflict. Analysing the positions and interests of stakeholders is vital in effective environmental conflict management. This paper reviews the literature related to stakeholders and their dynamics in environmental conflict. It also presents the results of a study relating to a New Zealand transport infrastructure project where the positions and interests of stakeholders have kept on changing during the life of the project. This study plots the changing positions of some of the key stakeholders, towards this project. These stakeholders include a policy manager, a community stakeholder, an environmental stakeholder and a political stakeholder. The paper also analyses the changing positions by identifying and classifying the key drivers for these changes. 相似文献

Smoothing techniques are mainly used to solve the problem of sparse data for statistical language model. The present smoothing techniques deal with the data sparse problem using different discount and compensate strategy, and they have different merit or shortcoming on complexity and rationality. This paper presents a new kind of smoothing technique based on global discount for Bi-gram model. The model parameters, probabilities for bigram, are discounted according to frequency of bigram, and are compensated according to lower-level model for unseen events in the model, whose rationality is indicated by minimizing the perplexity. Experiment results show that the technique is superior to commonly used Katz smoothing technique. 相似文献

Valuation based on the bill of quantifies will change the existing valuation mode of tender and bidding. For the standardized management of tender and bidding for power projects and the inteUigentized information management of power enterprises, it is an inevitable trend of reform to apply the valuation mode based on the bill of quantifies. According to the characteristics of power projects, this paper expounds the working process of the valuation mode based on the bill of quantities and analyzes the goal and function need of the tender and bidding management system. Considering the calculation procedure of the valuation and the quote strategy of quantities bill, the composition of fees for the valuation is settled and the calculation method is designed. To establish the management system of tender and bidding with a valuation based on the bill of quantities is beneficial for the costing reform of power projects and the perfection of the tender and bidding market. Therefore it is of great significance to spread the new management mode of project costing with a valuation based on the bill of quantities. 相似文献

Since the implementation of the new construction system in 1988 in China, this system has gone through three phases: trial phase(1988-1993),development phase(1993-1995),and comprehensive application phase from 1996.Construction supervision as a new management system has profound effects to the whole process of a construction project, in particular, to the three conventional objectives, that is quality, cost and construction time. The new management system has to a large extent brought the traditional problems of extended construction time, uncontrollable cost and unsecured quality to a normal practice. Construction supervision is a management activity with request of high intelligence. The performance of this activity is closely related to the quality of project general supervision engineer. This paper identifies the basic elements that a proper project general supervision must have. By applying the fuzzy analysis principle, this paper presents a quantitative model for evaluating the quality of project general supervision engineer.It provides an applicable approach for project clients when general supervision engineers are to be chosen. 相似文献
