用基于流事件结构的偏序时序逻辑刻画并发系统多诱因特征

Specifying Multi-enablings Using flow Event Structure Based Partial Order Logic

针对如何利用偏序时序逻辑刻画并发系统多诱因性的问题,提出了一种依赖流关系的流事件结构逻辑(FESL),作为多诱因特征的刻画语言。FESL以流事件结构作为框架模型,并且依据格局量词,建立了自己的公理系统。证明了FESL不仅能有效表达多诱因特性,而且还能描述涉及多个运行实例的特性;同时也证明了FESL的完备性、合理性以及可判定性。

In order to efficiently specify multi-enabling property which is an important character of concurrent systems using partial order logic, a new logic, flow event structure logic （FESL） , was proposed. Flow event structures served as models for supporting the specification for casual properties between runs of concurrent systems, and two extra configuration qutifiers “A” and “E” which specifies the properties of configurations were introduced to establish the axiomation system for FESL. Completeness and soundness of axiomation system for FESL were proved. The proof showed the logic the power of specifying multi-enabling property.
