    This paper surveys the recent developments and future research opportunities in computer supported cooperative work in design. This domain of interest has been variously conceptualized and described in different publications. There is a broader interpretation that considers the entirety of product lifecycle as a target domain and aims at a holistic optimization of all related engineering processes by connecting them through design. There exists a narrower interpretation that concentrates on the enhancement of the product conceptualization and creative design activities in distributed, multidisciplinary and volatile environments. The former is most frequently referred to as collaborative engineering and the latter as collaborative design. The paper concentrates on collaborative design and investigates the concepts, advancements and issues from: (i) philosophical and theoretical, (ii) technological and infrastructural, (iii) organizational and methodological, (iv) social and cultural, (v) cognitive and behavioral perspectives. Based on literature sources and the own work of the author in the last three decades, it provides a broadly-based analysis of the related concepts, knowledge, means, systems and concerns in current research, development and application with the objective to point towards future progression opportunities. The paper identifies a gradual shift in the research interest from the technological and procedural aspects to the socio-cultural, inter-personal and informational aspects. It proposes that collaborative design is eventually about people and that mobile, ubiquitous and smart technologies create many new opportunities for conducting collaborative design. Semantics, pragmatics and apobetics of inter-personal interaction and communication play a key role in the success of collaborative design. View full abstract»

    This paper presents a new approach for real-time collaborations in adaptive manufacturing, including web-based remote monitoring and control of an industrial robot, and active collision avoidance for human-robot collaborations. It is enabled by using virtual 3D models driven by real sensor data and depth images of human operators. The objectives of this research are to significantly reduce network traffic needed for real-time monitoring over the Internet and to increase the human safety in a human-robot coexisting environment. The results of a case study show that the approach consumes less than 1% of network bandwidth of traditional camera-based methods, and is feasible and practical as a web-based solution.

    In this paper we propose an architecture of intelligent agent for automatic locomotives operating. The system agent generates its action policy using a set of resources, such as type of railway, composition, belief perception and reasoning about the actions. The focus of the operator agent is directed to the choice of acceleration points (gear) and preparation of travel plans in a journey guided by goals and objectives. The system is equipped with a module capable to plan the actions to move the vehicle from an initial point P to an end point Q and an executor module that implements the generated plan and modifies the state of the environment. For this purpose, we use the mental model that is based on the triple Belief, Desire and Intention (BDI) to which the perception of the agent is guaranteed by a set of sensors that provide speed information, position and breaks condition. The main focus on this research is the usage of mental model BDI for the resolution of a problem that combines travel naturally conflicting factors, such as safety, time and fuel consumption. Experimental results show that the developed architecture using the mental model BDI increases the efficiency of autonomous vehicles operating. View full abstract»

    Due to the lack of efficiency communication and collaboration among each manufacturing department, it makes long lead-time and high cost for the manufacturing of aircraft structure parts which have the characteristics of multi-varieties, complexity structure, and small batch. In order to address these challenge issues, a feature-based and multi-agents-based manufacturing collaborative framework which includes process planning agent, NC programming agent, fixture designing agent, cost estimation agent and production management agent for aircraft structural parts is proposed, and the collaboration among each other is realized based on feature, the collaboration between fixture design and NC programming is described in detail. The prototype developed based on the framework has been utilized in a large aviation enterprise, and the result shows that the lead-time and cost are decreased. View full abstract»

    The existing methods of Web Service Composition (WSC) seldom consider the initiative and dynamic adaptability of Web Service (WS), which cannot make WS perceive the change of users' requirements in the changeable network environment. The result leads to the failure of Automatic Web Service Composition (AWSC). Meanwhile, the quantity of WS is so large in the existing network environment that the result of the AWSC does not meet users' requirements. Therefore, to improve the success rate of AWSC and solve the optimization of WS, on the basis of establishing the model of AWSC guided by the users' demand, this paper puts forward an optimal model of WSC based on particle swarm optimization (PSO) algorithm with Quality of Service (QoS) constraints, then illustrates the feasibility of the model by simulation results.

    The development process of the Airborne Force Cooperative Command System (ACCS) is a very complex and dynamic procedure. It is difficult to analyse quantitatively the event of all constituents. In this paper, the domestic and abroad applications of emulation techniques in cooperation are discussed. The overall structural model of the Airborne Force Cooperative Command System based on MAS (Multi-Agent System) is built up together with the structural model of the individual agent based on the BDI (Belief-Desire-Intention) architecture. In the end, a formal language is used to describe the process. View full abstract»

    Task assignment problem is one of the important research topics in a multi-agent system. It is desired to assign each task to a suited agent with a minimum total cost. For the advantages of memory, multi-character, local search and the solution improvement mechanism in artificial bee colony (ABC) algorithm, a task assignment approach based on ABC in a multi-agent cooperative design system is proposed in this paper. Experimental results demonstrate that the optimal solutions obtained by the ABC algorithm are better than genetic algorithm and particle swarm optimization on solving some task assignment problems.

    To improve the stability and reliability of the ETL workflow engine, in this paper, we put forward a new MAS-based and fault-tolerant distributed ELT workflow engine which is used to study the log management and exception handling mechanism in the distributed computing environment. In the new engine, the ETL jobs will be split into several job domains firstly. Secondly, when an error happens in a job domain, the engine will catch the exception from the error logs and then invoke our new recovery algorithm, Batch, to recover the job domain. The experiment result shows that our engine is not only much more stabile and reliable but also more efficiency in the execution of ETL workflow. View full abstract»

  • An agent-based dynamic scheduling approach for flexible manufacturing systems

    Page(s): 59 - 63

    The paper presents a dynamic scheduling approach for flexible manufacturing systems (FMS). The scheduling approach is implemented based on the negotiation and collaboration between agents in a multi-agent system (MAS) which represents the FMS. Through the collaboration between the agents in the MAS, the system exhibits the behavior that response to the disruption caused by dynamic events arise randomly in FMS such as jobs arrive over time and machines breakdown in real time and globally. The scheduling and controlling process is done on-line, without interrupting the system's operation and without user intervention. An experiment is conducted to evaluate the efficiency of the scheduling strategies exhibited by the proposed agent-based scheduling approach. The results demonstrate the superiority of the suggested scheduling approach as well as its capacity to cope with a fast changing environment. View full abstract»

    Computer simulation has already become an indispensible means for complex system developments, and the multi-agent oriented modeling and simulation is one of the most influential methods. In order to support multi-agent oriented simulation, a distributed platform is designed and developed to support the whole process that includes modeling, deployment and simulation. This platform can support uses to define the multi-agent models in a visual way and submit it as a sharable simulation model, which can be instantiated as simulation cases by other users. This platform also supports multiple simulation cases run concurrently. The execution engine can allocate agents to different machines and maintain the balances of loads across these machines. In this paper, the system structures together with the mechanisms behind the platform are introduced. View full abstract»

    The IT OA -office-aid- assets (ex. PC, Telephone ... etc.) are required tools for most office workers in an enterprise. The process from ordering to dispatching the composite OA assets for new employees itself is a supply chain within a company. This study aims to save man power, increase process efficiency and resolve the supply chain issues beneath the operation by reengineering the process and integrate the multi-sites, multi-roles/tasks into a multi-agent-based collaborative cloud application service. At last, empirical data supports that process time is gained and thus earlier issuing the IT OA composites is also achieved. The other attributes of this study include: (1) agent-based collaborative platform converts batch processing of centralized management into parallel information processing; (2) the simplified interface allows users to get the picture of the entire flow at a snap shot. Meanwhile, cloud-based utilization can be adopted by the company subsidiaries with the similar processes. View full abstract»

    The motivation of Web service comes from its interoperational ability so a large number of Web services can interact with others and constitute an open network, Web service network. The success of Web services selection rely on, not only its Qos capability advertised, but the trustworthy of QoS to large degree. How to evaluate the trustworthy of services QoS information, however, is a challenge in Web service network. Reputation system, a mechanism which assesses the future QoS performance by the past behavior of service, is one of promising approaches to facilitate users make optimal decision. In this paper, we present a hybrid framework of reputation model for Web service. Based on this hybrid architecture, clients build their specific social communities, by which they obtain service's prior reputation. At the same time, the central reputation system fuses the rating data from clients by bayesian estimation. The result of experiments illustrated our approach is more efficiency and accuracy in several aspects, especially when dealing with strategics services. View full abstract»

    Real-time collaborative programming environments support a team of programmers to edit the same shared source code document concurrently over communication networks. This paper presents the design and implementation of a novel real-time collaborative programming system named CoEclipse, which transparently converts the single-user Eclipse IDE into a multi-user real-time collaborative programming tool, incorporates and integrates syntactic and semantic consistency maintenance techniques derived from our prior work, and provides advanced awareness features for supporting semantic conflict prevention. The novelties of CoEclipse include its full compatibility with existing single-user programming environments in terms of user interfaces and working processes, seamless integration of syntactic and semantic consistency maintenance features, and providing complementary approaches of awareness and locking in collectively supporting semantic conflict prevention. Furthermore, the CoEclipse approach in supporting advanced real-time collaboration is generic, which can be applied to other application domains for achieving similar design objectives and rationales.

    In 3D collaborative modeling systems, users need a convenient mechanism to repeatedly modify the models they are operating on. In this paper, we contribute a selective undo/redo solution for users to select arbitrary operation to undo. With the consistency maintainence mechanism we proposed, operations need to be re-arranged on each site for after their arriving. Both history buffer and model state stream are adopted to present the arriving sequence of operations and their actual execution sequence. In case of concurrent undo/redo, undo state vector is proposed to make sure that an operation can only be undone once and redone by the designer who undoes it. Based on all the precautions we have made, an undo/redo algorithm is proposed. The algorithm has been verified in the prototype we implemented. View full abstract»

    In some mechanical transmission structures, the conjugate cam mechanism is used widely. The previous design method is not only tedious, but the substantial design is not strong, difficult to form a simulation animation, and inconvenient for subsequent analysis. The equations of conjugate cams curves are derived by the analytical method. Taking the conjugate cam in beating-up mechanism as an example, three-dimensional parametric design is implemented with Pro/Engineer secondary development. And then the after design model is imported into ADAMS to do simulation. Such an approach not only makes the design of analytical method become much simple but also makes the subsequent analyses become even more intuitive, as well as, increasing design efficiency and quality, shortening the development cycle. It has some practical value in practice. View full abstract»

    Autonomous Systems (ASes) discover routing paths to the destination AS via BGP announcements advertised by neighbor ASes. However, the actual packets forwarding path may be inconsistent with the announced routing path. The inconsistency could cheat rational ASes to bring a massive commercial benefit to malicious ASes, and cause a great damage on the stability of Internet. Prior work on this issue could be summarized as path verification in the control plane and path probing in the data plane. These countermeasures could not discover the problem in time, and have a lot of overhead. In this paper, we design a Routing Collaboration Accountability Mechanism that enables the source AS of the path to discover the inconsistency. The source and destination AS collect analysis results of forwarded packets in a certain time interval to generate routing evidence. Making use of routing evidence, they collaborate with each other to verify the announced path. It is a lightweight mechanism without packets modification and be suitable in high packet rate network. The evaluation results show that it has less overhead than other methods. View full abstract»

    Even though there exists a number of search solutions targetted at software engineers the literature suggests that they are not widely used by the people engaged in code delivery [26]. Moreover, current code focused information retrieval systems such as Google Code Search (discontinued), Codeplex or Koders produce results based on specific keywords and therefore they do not take into account user context such as location, browsing history, previous interaction patterns and domain expertise. In this paper we discuss the development of task-specific information retrieval systems for software engineers. We discuss how software engineers interact with information and information retrieval systems and investigate to what extent a domain-specific search and recommendation system can be developed in order to support their work related activities. We have conducted a user study: a questionnaire and an automated observation of user interactions with the browser and software development environment. We discuss factors that can be used as implicit feedback indicators for further collaborative filtering and discuss how these parameters can be analysed using Computational Intelligence based techniques.
