In many CSCW systems, mobile agents are used to do some important work. However, mobile agents add a notable amount of complexity to all common problems of distributed systems, and cause a couple of new ones, such as location management, ji-tquent disconnection and migration, etc. In this article, we focus on the technique for strong migration of mobile(More)
This paper presents a construction approach for software agents. A software agent is regarded as a main frame plus some components, and it is constructed by selecting suitable main frame and software components, assembling and running through the control mechanism on the main frame. The multi-agent system is organised on the Client/Server model. The(More)
-This paper compares five distance-based statistics (Hopkins, Cox-Lewis, Eberhardt and two Tsquare statistics) which reflect the degree to which a set of d-dimensional points is random. The objectives are to identify the most promising statistic for intensive study and to establish performance bounds for situations involving little prior information. The(More)
This paper proposes a domain-specific software architecture style. In the architecture style we define three software component types: procedure components, object components and agent components. We design a software bus or connector called Tribus to facilitate interactions among these components and specify one way quotation relations between different(More)
Optimal workplace coalition generation is a key technique in migrating workflow. A trust model that describes cooperation relationships among workflow entities is presented. Different from traditional trust models, the trust model organizes confidence of a workflow engine in a workplace by two categories, capability confidence and recommendation confidence.(More)
An experience based trust model in migrating workflow is proposed. In the trust model, security and capability are considered in a cooperation evaluation, a cooperation evaluation sequence is updated according to update strategies and the trust degree is acquired using the trust degree formula. Self-confidence of the workplace is defined based on our former(More)
