Abstract: Active service is a kind of Web service which can be customized by customer’s requirement. The development of component technology provides foundation for the implementation of active services. Based on UCDL, the key technology of Local Component Resource Warehouse (LCRW) is expounded, the model of component library based on active service is constructed, the organization method by facet classification combined with ontology information classification is proposed, and the component retrieval based on Ontology Information is also proposed in view of facet retrieval.

Abstract: Food is the most basic material conditions of survival and development of human society, its security situation is relation to the health and safety of consumer directly. This paper analyze the reasons of causing problems of food quality and safety in the agricultural products supply chain from the perspective of the game theory as well as the government incentive and regulatory mechanisms affect the decision-making of farmers and food producers respectively. In the game between crop growers - farmers and food producers, the government play the outsider role and should give farmers subsidies to encourage them to grow high-quality green crops, as far as possible to ensure food safety from the source. In the game between producers and regulators, the government, as the game participant, should be asked to improve the supervision efficiency and the control ability to prevent unqualified food products entering the market.

Abstract: In this work, the notion of an 3-band generalized multiresolution structure (GMS) of sub- -space L2 (R) is proposed. The characteristics of affine pseudoframes for subspaces is investigated. The construction of a GMS of Paley-Wiener subspace of L2 (R) is studied. The pyramid decompo- -sition scheme is obtained based on such a GMS and a sufficient condition for its existence is provided. A constructive method for affine frames of L2 (R) based on a GMS is presented.

Abstract: In this paper, we introduce a class of vector-valued wavelet packets of space , which are generalizations of multivariate wavelet packets. A procedure for constructing a class of biorthogonal vector-valued wavelet packets in higher dimensions is presented and their biorthogonality properties are characterized by virtue of matrix theory, time-frequency analysis method, and operator theory. Three biorthogonality formulas regarding these wavelet packets are derived. Moreover, it is shown how to gain new Riesz bases of space from these wavelet packets.

Abstract: Manufacturing system is a typical complex system, while task assignment problem is an important topic in manufacturing system. It is one of the most difficult problems in the theory research for manufacturing system. In this paper, task assignment model in manufacturing system was modeled with the concept of Holonic Manufacturing System including basic system model, communication model, represent model and optimization model. Task assignment model based on operation cost and lead time is applied to cooperative activity among orders in a Holonic community. A hybrid PSO algorithm was utilized to the combination of the task assignment problem. Simulation result shows that the model and the algorithm are effective to the problem.

Abstract: The rapid changes of market and outer surroundings have caused a dynamic and highly volatile business environment for the enterprise. Manufacturing organizations are seeking efficiency gains by competing via fast time-to-market and low production cost. An Autonomous Agent Network(ANN) Based Manufacturing System model is introduced, as well as the mathematics expression for the components of AAN model. The optimization algorithm based on evolution algorithm is used to solve the optimization problem of the model. Simulation results show that the architecture model and its optimization algorithm are effective to the problem.

Abstract: Rules play a central role in a wide variety of applications. In addition to the declarative specification of business rules, the simple rule engine design described in this article can be used to implement state machines, predicate dispatchers, or any other rule-based system. This paper introduces how to design a Rule Engine System with SQL Server 2008.

Abstract: This document applied the intelligent agent technology into web-based education platform, which make web-based education more humanized, get further popularization and widely used. In the article, we introduced a web-based intelligent tutoring learning system. It could flexibly organize learning materials according his individual requirement providing personalized learning environment. The idea the based theory learning contents organization the key technology, system structure and how to realized it are all be dissertated. The web-base education has become a research focus; answer system on-line is an important part of it. In this paper, we introduce the concept and characteristics of Intelligent Agent technology, and propose a design plan about Intelligent Agent based answer system on-line.

Abstract: Manufacturing Execution System (MES) links plan management and workshop control in an enterprise, which is an integrative management and control system of workshop production oriented to manufacturing process. To overcome the difficulties of traditional software development method, development of MES based on component is adopted to prompt development efficiency and performance of MES, which can be more reconstructing, reuse, expansion and integration, and MES domain analysis driven by ontology is investigated in detail. MES domain analysis driven by ontology is feasible and efficient through developing a pharmaceutics MES which applied in a pharmaceutics manufacturing factory.

Abstract: As more and more resources are integrated in enterprises, or between enterprises or industries, the information integration must encounter all kinds of problems which should be solved in production system. The paper discussed integrity constraints in information integration which were found in production system, and proposed solution for the problem.
