中文摘要：

针对可穿戴计算技术在企业现场设备维护类作业辅助应用系统调度方面的需求,基于已建立的辅助应用构建模式,提出上下文适应度、效用因子、风险因子等约束,用于描述影响辅助系统的上下文知识和行为规则;提出一种新的扩展模糊有色Petri网形式对这些约束进行形式化描述,并在其基础上构建辅助应用系统的形式化模型。针对该模型研究动态调度方法,为辅助应用系统提供决策知识。最后给出了应用实例和分析。

英文摘要：

Aiming at the application requirements of wearable computing technology in enterprise on-site task assistant system scheduling, based on the existing assistant application construction patterns, some new constraints about context fitness, utility factor, risk factor, etc. were put forward to depict context knowledge and behavior rules which affected On-site Task Assistant System （OsTAS）. Then, a new Extended Fuzzy Colored Petri Net （EFCPN） was presented to formally describe these constraints, and to construct formal model of OsTAS with EFCPN. A new dynamic scheduling method was put forward for this formal model and to provide decision knowledge for OsTAS. Finally, application examples and analysis were provided.
