The research question here is “how to effectively integrate the R&D experts and software developers to realize an effective R&D project collaboration software?” This research conducted a case study on the deployment of an integrated development methodology in a world-class semiconductor manufacture company. From the case study, the integrated methodology, Development Collaboration Diamond Model (DCDM), was designed, implemented and obtained the dramatic performance.

The bumpless switching is a concept from cybernetics. It refers to the smooth switching condition when a new system replaces the old one in operation. We implemented the dynamic reconfiguration of SoC based on delta MPU architecture to reach a bumpless switching. The dynamic reconfiguration of SoC with bumpless switching depends on a co-design of some bumpless switching algorithm and a SoC hardware with delta core structure. Since bumpless is a desired condition in system switching, the scheme is significant for the dynamic reconfiguration of SoC.

The authors of this paper participated in the project Framework 6 and the Lincoln Institute of Land Policy Fellowship. One of the above project’s goals was to develop and improve a Real Estate’s Market Value, and the Pollution and Health Effects Analysis Decision Support System (RE-MVPHE-DSS). RE-MVPHE-DSS consists of a market value analysis, air and noise pollution, premises microclimate, health effects, voice stress analysis, complex determination of the weights of the criteria, cooperative decision making and multiple user subsystems. RE-MVPHE-DSS is briefly analysed in this paper.

In this study, an Agent-Based Collaborative Scheduling System is represented as a model of scheduling among shops. Agent-based system describes the behaviors of distributed decision maker agents in manufacturing systems. Agents in the system are Production Planning Agent and Shop-Floor Agents. Shop-Floor Agents are semi-autonomous agents so that the degree of autonomy is determined by the Production Planning Agent. The distributed system forming heterogeneous units was designed by hybrid control architecture. The study focuses on constructing an Agent-Based Collaborative Scheduling System that is capable of conducting scheduling negotiations among shop-floor agents. The designed system is capable of scheduling by considering heterogeneous objectives of the shop-floor agents within a collaborative manufacturing environment. Negotiation is co-operative not competitive. Shop-Floor Agents generates collaboratively their schedules. The schedule for the best interest of the system as a whole is selected by the Production Planning Agent.

The determination of the investment project risk is an important stage in cooperative decision-making and in choosing the most profitable project with the lowest risk level in engineering and construction. Risk management is a systematic process for integrating professional judgments about relevant risk factors, their relative significance and probable adverse conditions and/or events leading to identification of auditable activities. The paper aims to present a verbal method of determining investment risk in construction. The main problem considered is the assessment of investments, which depend on the risk level. This article presents a new way to solve the problem - the CLARA expert verbal method. Formally, the problem is stated as one of multicriteria classifications. A hierarchical approach to the considered effectiveness indicators is proposed. The proof of the method effectiveness is presented. The process of method’s practical application is described.

In workflow and grid environment, the security challenges with the appearance of composite service increasingly become more severe than before especially to the traditional static access control model and dynamic authorization model. To solve these challenges, we presented a Dynamic Access Control Prediction mechanism for service workflow on the basis of Markov Chain. In fact, this prediction mechanism is only one part of the larger system, platform (CAP), which is totally composed of three key modules-— composite-service pre-processing, result feedback, and authorization prediction. In this paper, we present the design of its architecture as a whole.

This paper presents a document recommendation system based on clustering peer-to-peer networks. It’s an unstructured P2P system. In this system each agent-peer can learn user’s interest, then it helps user share and recommend documents with the other users. Since each peer in our P2P networks is a node, in order to cluster them, we import the concept of Group. Each group is composed of peers. The types of documents, which belong to a same group, are uniform. This paper presents how these peers help users to share and to recommend documents, and how they cluster into groups. Our experiment results show the advantages of the document recommendation system.

With the gradually extending of problem application scale, science and engineering computing becomes more and more complicated. Designing a collaborative problem solving environment aiming at specific fields is becoming more and more important. In order to integrate various heterogeneous resources and provide a flexible problem solving environment, we proposed a novel grid approach: SECGrid (Science and Engineering Computing Grid). SECGrid provides a dynamic grid application deploy environment. A grid portal is also adopted to present grid application from diverse sources in a unified way. We proposed a new scheduling algorithm (Application Demand Aware Algorithm) to make job scheduling more feasible. Moreover, SECGrid provides a lot of useful facilities, such as grid accounting, grid monitoring, etc. In the practical application, SECGrid encapsulates lots of computing modules from science and engineering, and provides an easy way for collaborative problem solving.

Data-driven media streaming has been deployed gradually over the Internet. In such systems, node periodically exchanges media block availability and fetches desirable blocks from neighbors. The issue on optimizing fetching blocks is called block scheduling and receives focus, especially in heterogeneous overlay. In this paper Bandwidth-Aware Scheduling (BAS) formulates such problem by incorporating bandwidth and block deadline, as well as node importance. Simulation results verify that BAS performs much better than existing ones.

In a global world we face the necessity for worldwide collaboration and long-term co-creation. We know different kinds of internet platforms and examples of successful remote team work within projects for a limited time but we do not have much experience about computer sustained communities working successfully beyond projects and generations with different cultures and conflicting interests. The challenge is to build and to maintain a very specific kind of virtual community realizing a successful mix of “real” (face-to-face) and “virtual” (remote) qualities creating a platform for successful dialogue between diverse points of view. The contribution describes key qualities for creating such communities. It is about how to build the bridge between technical potentials and human qualities for establishing cross-cultural and long-term processes beyond face-to-face work. The presented experiences are based on the creation of an open and frank dialogue culture consequently using cooperative visualization from the first step of the collaboration process.
