In the same way, the ability to respond rapidly to changing market opportunities by quickly providing the required combination of design and manufacturing capabilities becomes a key issue to maintain competitively. In this context, the concept of virtual enterprise takes an increasing importance in supporting future business engagements and fulfilling technology requirements. As short-term consortia of companies to address fast changing opportunities, the virtual enterprise may be modeled by a multi-agent system representation. Such an approach allows modeling the heterogeneous actors of the real world in terms of agents, focusing on communication and collaboration between them. The feasibility of the multi-agent approach has already been demonstrated in the manufacturing and financial fields. This paper shows how a multi agent approach may be used in the modeling of virtual enterprises. An example of an agent, the \"controller agent\", will be described in details. The multi-agent system used, called PVS98, has been developed in the framework of an Eureka project. It relies on a KQML-like architecture and on an enterprise ontology.","PeriodicalId":194923,"journal":{"name":"Proceedings Ninth International Workshop on Database and Expert Systems Applications (Cat.

In ROLAP however, cube creation queries need to be issued repeatedly in order to search for useful features (i.e. rules or patterns) within large scale databases. The cube creation cost can be a bottleneck in the whole ROLAP processing. The cost of the queries can be effectively reduced by estimating the query results using samples. To maintain the accuracy of ROLAP even when using samples, the samples need to be extracted in an appropriate unit. However, conventional query optimization methods only support record based sampling and cannot be applied for complex queries that have other sampling units, such as the ones that include grouping aggregate operations. We develop a query optimization method named SUPRA that preserves the sampling unit used in random data extraction. The method is designed to preserve both the sampling unit and the randomness of the sampling operation. Using this method, typical ROLAP queries can be transformed into more efficient ones than those obtained through conventional methods.","PeriodicalId":194923,"journal":{"name":"Proceedings Ninth International Workshop on Database and Expert Systems Applications (Cat.
