OPS产生式系统及其并行执行

OPS Production Systems and Its Parallel Excuting

本文叙述了产生式系统OPS5的文法、执行方式和用于匹配的操作RETE算法。从OPS5的文法分析角度论述了OPS5包含三个级别的五种并行性,并依据静态和动态特性数据对OPS5并行性的开发进行了分析。最后介绍了国外开发产生式系统并行执行模型和并行产生式系统机的现状。

The Syntax and the excution cycle of production system OPS5. and the RETE algorithm for the Metch are described. The five parallelisms in three levels of the OPS5 are analyzed from the point of view of syntax anaylsis. The parallelism's development is discussed on the basis of the performance which measured by Gupta for OPS5. Finally, the parallel excution model for production system and the parallel production system machine, both existing and proposed in other covnity are described.
