In order to realize STEP-NC-oriented computer numerical control machining and achieve optimal performance in manufacturing, a multi-agent system for process planning in STEP-NC based manufacturing was designed. By analyzing the characteristic of STEP-NC data model, a manufacturing feature-oriented process planning method was proposed in this study and the distributed artificial intelligence met...

Service oriented architectures (SOA) herald a new generation of application systems. Whereas current systems were to be chosen and operated as self-contained systems of individual vendors, service oriented architectures allow for integrating application functionality from different sources internal or external to a company according to individual needs within a specific context. Vendors of ERP ...

This work presents a methodology to incorporate reliability constraints in the optimal power systems expansion planning problem. Besides Loss Of Load Probability (LOLP) and Expected Power Not Supplied (EPNS), traditionally used systems, this proposes use of risk measures VaR (Value-at-Risk) CVaR (Conditional Value-at-Risk), widely financial markets. The explicit consideration problem can be an ...

We present an approach of a distributed planning method to solve dynamically some typical tasks of a production planning system in a exible manufacturing system (FMS) at control level without using a xed central component during planning and execution of orders received by one or several production planning systems above the control level. To achieve this, a exible manufacturing system has been...

Internet software is an emerging software paradigm. Traditional evaluation methods for software reliability are no longer applicable because of the open and dynamic characteristics of the Internet software. In order to evaluate its reliability accurately, there must be a dynamic and open reliability evaluation approach. This paper presents the collection approach of the reliability-related data...

Service Reliability is an important consideration for new service deployment. Traditional system-oriented measures are no longer adequate to describe the reliability perceived by the user. In this paper we propose a general service reliability analysis approach based on user behavior, and derive formulas to compute service reliability from the user model and service models. The derived user-per...
