摘要: 过程模型在企事业单位中的应用日益普遍.由于企业为每个特定业务需求单独开发过程模型是复杂并且高成本的工作,因此企业通常使用参考过程模型作为过程模型开发的基础,以有效降低成本并提高开发效率和质量.由于参考模型需要领域专家大量的领域分析和抽象建模工作,如何基于领域内已有的过程模型变体自动创建出初步的参考模型以辅助领域专家的工作成为有意义的研究问题.现有的参考模型构建方法存在输出模型复杂度较高或难以全面表达领域内多样推荐实践等问题.为了创建代表性和可读性更强的参考模型,基于相似过程片段聚合技术,提出了一种支持层次化子过程结构的可定制参考过程模型的自动构建方法,全面支持可定制参考模型中基础过程、变更可选项以及约束关系的自动构建.案例研究结果表明:该方法生成的参考模型具有良好的领域代表性和模型复杂度.

Abstract: Process models are becoming more and more widespread in contemporary organizations. It is a complex and high-cost work to develop individual process models for specific business requirements. The modeling procedure can be accelerated and cost-decreased by using reference process models as a basis for individual process models development, so reference process models are widely adopted by organizations. Because building reference process models requires a mass of modeling and analyzing work by domain experts, a major challenge has emerged that how to automatically build a preliminary reference model inductively based on the existing process variants to provide assistance to domain experts. The existing methods of building reference process models have some shortcomings, such as output reference models of most methods have high model complexity and reference models described by traditional process modeling language could not entirely represent various recommended practice in a specific domain. To build reference process models with high representativeness and understandability, this paper proposes an approach to automatically build customizable reference models which support hierarchical sub-process based on fragments clustering. The base model, change options and constraints in customized process models are fully supported to build automatically by our method. The evaluation results show that the generated reference models could achieve fine domain representativeness and model complexity.

Key words: process model, process variant, reference model, customizable process model, process fragments
