Application of Function Analysis in Conceptual Design

Product design is a procedure that enterprises meet the needs of consumers; conceptive design is one of the steps in product design and it directly considers requirements of consumers. So how to supply consumers with satisfying function is the essential point. On the basis of function analysis of Value Engineering, the paper puts forward a new method to exercise function definition and function analysis, implements conceptual product design procedure with database techniques.A new way is gotten to convert requirements to conceptual product.     

An Analysis of Principal-Agent of Game under the Asymmetric Information in Venture Capital

The relationship of investors and venture capitalists is an important part in venture capital. Based on asymmetric information, this paper analyzes the principal agent relationship between investors and venture capitalists with game theory. And this paper mainly discusses the choosing, controlling and incentive problem. It suggests that only the capable and self confident venture capitalists could accept the terms of the limited partnership. It also indicates that recompense mechanism which holds the interest of investors and that of venture capitalists tightly is the center of the limited partnership. Rate of yield is the key of recompense mechanism, it not only reflects the incentive on venture capitalists, also reflects the share of risk between investors and venture capitalists. At last, the market credit play an important role in venture capital.     

Resource Management in Application System

Application system generally refers to all kinds of computer information system. It aims at improving the sharing and application of the resource. The resource in application system usually means data resource. For computer management and maintenance, there are not only data resource, but also program resource and network resource. Effective management of this resource is key to ensure proper work of the application system. In this paper, the basic pattern and policy for resource management is put forward and a method to build and realize the resource layer that lies between database layer and application layer is to be found. This management layer, which skillfully connects the application system with resource and establishes good base for application and exploitation of system, is named as resource management system.     

A Research of Life Cycle Integrated Management Pattern of Construction Project

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.     

Learning the BN Structure Based on the Sum of Mutual Information

The Crossing Entropy is defined to scale the similar level of two probability distribution. In many papers on learning BN structure,the Crossing Entropy was used as an indicator of measuring the learning accuracy of an algorithm.The known scoring metrics for learning BN structure is analyzed in this paper,then a new scoring metrics Sum of Mutual Information is proposed based on the information theory.At last,two algorithm for learning BN structure by SIM is represented.     

Practical Criterion for Voltage Stability of Substation

This paper presents a new practical criterion for voltage stability based on the real-time information at the substation and the quasi-time information from power system.By using the criterion,it is effective to predict the bus voltage stability margin.This is of great importance to raise the security operation level and prevent voltage collapse.The practical criterion for voltage stability is tested on the IEEE-14-bus test system.It needs less calculation time and is very suitable for real-time control of power systems.
