摘要： 为解决供应链采购的动态决策问题，提出一种情境感知的供应链采购决策方法。给出情境感知服务的概念，设计一种情境感知服务系统架构，定义情境空间，利用基于键值对的模型对情境空间进行建模，采用基于规则的推理方法，通过Drools规则引擎进行规则定义和推理。分析结果表明，该方法可以实现高效率的情境感知供应链决策。

Abstract: This paper proposes a context-aware procurement decision method in supply chain management. The context-awareness concept is introduced and the architecture of the context aware service system is also proposed. It puts forward the context space concept, and a key-value based context model is defined accordingly. Also the rule-based reasoning method is adopted in the model. An open source rule engine, Drools, is integrated into the system to perform rule definition and reasoning. The context aware decision method is testified by a purchase decision process in a supply chain procurement system.

Key words: context-aware service, rule engine, supply chain, Service Oriented Architecture(SOA)
