Research on Interface Management of General Contracting Projects

In recent years, EPC, as a project contracting model, has been promoted in the international and domestic markets. This mode can realize the reasonable intersection of design, procurement and construction, and can reasonably combine the three major businesses so that the whole project plan can be more optimized which is very beneficial to the management of the owner, and can effectively ensure the progress of the project construction. The achievement of the owner’s cost target. However, many participants are intertwined in a system, which will inevitably bring huge challenges to managers. For example, the goals of different participants are very different, which will form the interface between organizations. Based on this problem, this paper will systematically review the interface management, find out the influencing factors of the EPC project interface management through literature, and further screen and evaluate the influencing factors through expert interviews and questionnaires, so as to obtain six influencing factors: poor information processing ability, design work ignores buildability, security incident, too much intervention by the owner, use of new technologies, new materials and new processes in construction, uncertainty and changes in the surrounding environment, and carry out variance analysis of influencing factors for different individual characteristics and obtain factors such as “too much intervention by the owner”. Males have higher recognition and higher education than females. The higher the degree of recognition of this factor is, the highest degree of recognition of the supervision unit for “design work ignores constructability” is.

Cost-Benefit of Interface Management Improvement in Design-Manufacturing Chain

Design-manufacturing chain （D-MC） is the most important link of the supply chain with the greatest possibility in cost reduction. How to strengthen the effective management of interracial relationship between designer and manufacturer and increase the efficency of interface management concerns the efficiency of the whole supply chain. In order to evaluate and improve the impacts of D-MC interfacial relationship, first we should construct the evaluation index system and then we should analyze the total cost and benefit of the interfacial relationship betterment, including the cost of member units in D-MC, the opportunity cost of cooperation partners, and the market returns resulted from the interfacial relationship improvement, which will advance the whole supply chain efficiency as well as enhance the management performance of D-MC.

Framework to Design Type-based Transfer Processes Between Technology and Product Development

To stay globally competitive, manufacturing companies are increasingly under pressure to bring new products and applications to market, improve existing products, and discover new technologies to produce them at a lower price. New technological findings can enable companies to overcome these challenges. In practice, technology development associated with a long time horizon is often given a lower priority compared with short-term focused product development thus being stronger restricted by everyday business. More and more companies separate their technology development department from product development to promote technological innovations. Due to this additional interface in the R＆D organization new problems arise, resulting in technologies not being implemented in products. The reasons for these problems amongst others concern wrong timing for the transfer or inadequate definition of responsibilities. In this paper of ongoing research, authors introduce a framework to design the transfer processes between technology development and product development. Although there are a number of options for designing the operative transfer, there is no regulatory framework specifying which configuration options are at this particular interface. The approach is to develop a model, which is able to design different company-specific transfer processes taking into account the object being transferred at this interface. Thus, for different objects to be transferred, different transfer processes are designed. The model＇s aim is to enable responsibility of the R＆D management to design their company-specific transfer processes to enable more technologies being implemented into products, thus giving the whole company the possibility to act more innovatively.

基于DCMI的轻量级数据中心服务器管理

DCMI(Data Center Manageability Interface),即数据中心管理接口,是一套专门针对IPDC(Internet Portal Data Centers互联网门户数据中心)和其他高密度数据中心部署的服务器平台管理接口。这一接口标准的制定,对未来数据中心管理成本的降低,运营效率的提高都有着重要的作用。在云计算时代即将到来,对高密度服务器集群需求量增加的今天,这一标准将会得到长足的发展和充分的应用。

Colored Nets as a Formal Approach to Event-Driven Interfaces

Modern object-oriented interactive applications have a tendency to be dguult to specie and to des l'gnbecause of dynamicity A formal model based on the integration of communicative nets and colored nets withmpchronous channels is proposed ic cater for this need. Three kinds of nets modeling fore e components of interfaceare given in this paper.The model provides natural descriptions of multi-thread dialogs and the concurrent executingof user interface and aPPlication Procedures and can facilitate rapid protonning and automatic interface codegeneration.

An Approach to User Interface Specification with Attribute Grammars

An approach to supporting user interfaces using an attribute grammmar combined with an event model is described. The main emphasis is how to represent a multi-thread dialogue model in direct manipulation user interfaces. It is shown that control sequence within dialogues, communication with other dialogues,and some computations for applications can be specified with a syntactic and semantic notation. The attribute grammar specification can be implemented using an attribute grammar interpreter embedded in the runtime structure supporting communication, synchronization, and dialogue execution.

An Object-Oriented Multi-Thread Dialog Model

This paper presents a multi thread dialog model using extended state transition network model combined with an object oriented event model to specify and manage user interface. The model provides multi thread dialogs and the concurrent executing of user interface and application procedures. The forms of class based concurrency possible in the model emphasize the human computer interaction and exploit the concurrency across objects and within an object. Dialog descriptions using extended state transition networks, the automatic extraction of concurrency, the facilities for performing synchronization and communicating, generalization and specification, and the smooth transition from dialog design to programming language implementation are also given in this paper.

ADVANCE SELLING IN THE PRESENCE OF PRODUCT DIFFUSION EFFECT

Product diffusion refers to the phenomenon that the later demand is dependent on the early sales. To investigate how a firm＇s advance selling strategy is affected by the effect of product diffusion, we consider a monopolist seller who sells a fashionable product in a market that comprises of myopic and strategic consumers over two periods （i.e., the advance selling season and the regular selling season）. For a linear product diffusion effect we fred that, when the effect of product diffusion is positive, the seller may set an extremely high advance selling price to induce the strategic consumers to purchase in the regular selling season, which is counter-intuitive. Moreover, the optimal procurement quantity for the seller may increase in the negative effect of product diffusion and decrease in the amount of strategic consumers. When we extend our model to consider a concave quadratic product diffusion effect, however, the optimal procurement quantity is concave in the amount of strategic consumers. Numerical studies are further presented to discuss the managerial insights.
