For a service company, the very important persons (VIPs) can provide more revenues than regular customers. Even the number of VIPs is few, once operators miss or late to response calls from a VIP, the possibility of losing the revenues is potentially huge. Therefore, if a company needs to satisfy VIP's needs, the manager must provide two different services of call center. Because employee salary forms...
The Object Oriented (OO) paradigm has wide acceptance among application developers while Relational Databases (RDB) are commonly used by most organizations, but the two model systems, OO and RDB, are incompatible. Developers of database applications often face the problem of an inherent mismatch between the two models. This paper proposes integrating OO and RDB models into a unifying conceptual model...
Negotiation always plays an important role in multiagent system research. How to establish an effective negotiation model to improve the ability of negotiation of the agent is one of problems solved in multi-agent system. Based on answer set programs, this paper presents a new method about how to express the negotiation demands and how to establish answer set program of negotiation, and puts forward...
In this paper we present a novel technique called iDMI that imputes missing values of a data set by combining a decision tree algorithm (DT) and an expectation-maximization (EMI) algorithm. We first divide a data set into horizontal segments through applying a DT algorithm such as C4.5, and then apply an EMI algorithm on each segment in order to impute the missing values belong to the segment. If...
To meet the needs of desire of using natural language to describe data analysis, this paper combines ideas of both fuzzy query language and linguistic summaries, introduces fuzzy set theory and presents a more powerful algorithm based on relational database, which can find fuzzy rules among crisp data. As a result, an automatic fuzzy rule extraction system is developed, which can support users extract...
In this paper, an internet-like procedure for power management of MV electrical networks with responsive busses is presented. This procedure is based on the “token ring” internet protocol and considers a multi-level co-ordination of all active customers. It aims at reducing the complexity of distributed networks management while ensuring free customer participation in services for the grid support...
