摘要：

针对工作流的适应性受到活动路由、资源的数量和性能、角色的权限以及时间等约束的问题，提出工作流约束网络模型。在基于策略的工作流管理系统的基础上，使用软约束网络进行策略数值化和策略优化，工作流引擎根据结果做出策略决策。分析表明，该策略建模方法和策略决策方法在提高模型描述能力、降低模型复杂性，以及提高系统适应性方面有一定的优势。

Abstract:

The workflow adaptability is restricted by active routing, the quantity and performance of resource, the role’s authority, and time. To resolve these constraints problems, this paper presents a workflow soft constraints network model. Based on policy-based workflow management system, it uses soft constraints network to quantize policy and optimize policy, which are used to guide policy decision-making. Analysis shows that this method of model and policy decision-making has obvious advantages on improving model description ability, decreasing model complexity and improving system adaptability.

Key words: workflow management system, policy, soft constraint, adaptive, workflow
