Based on the analysis of the minimal conflict sets features and the intersecting-side algorithm, this article present a method for extracting the minimal conflict sets,it is shown by an example that the minimal conflict sets to distinguish and solve constraint conflict validity under the designe.

Studied the collaborative design function request, the overall concept with emphasis, product management, instance manage, the conflict restraint and so on key technologies, the development collaborative design system has provided the new working platform for the enterprise, reduced development cycle, obtained the good economic efficiency.

Recently, the Workflow Management System (WFMS) becomes more and more popular, those that have existed can simulate flow logic of the business process, but cannot simulate business constraint.

So,in this paper,we introduce the concept of business constraint,create a model of business constraint,give a scheme to combine business constraint with flow logic,and present an implementation of business constraint in existing workflow management systems.

Research on Immunology-Based Online Detection and Resolution Method for Feature Interaction;

Research on Method for Immunology-based Feature Interaction Online Detecting in Next Generation Network;

The completeness and correctness of detection rule set are key points to enhance the real-time detection rate of the feature interaction manager(FIM).

Solution to mediate service conflict between presence system and videoconference system;

This paper introduces the signaling flow and character of color ring back tone (CRBT) based on intelligent network (IN) firstly, then discusses the service conflicts between all kinds of call forward (CF) services and CRBT, and provides three solutions of the conflicts.
