chaining forward

The conclusions and the experience knowledge from the experts in this field comprise knowledge base of the fault diagnosis expert system ( ES). The control strategy of the inference engine consists of forward chaining and backward reasoning.

将分析结论作为故障诊断知识，结合经验知识等建立故障诊断专家系统知识库，运用正向推理与反向推理相结合的推理控制策略进行推理。

Additionally, fuzzy inference path is put forward for backward chaining inference.

而在反向推理中, 采用了模糊推理路径.

A forward and backward chaining inference engine suitable for this problem is derived and discussed.

建造了适合本问题的正、反向混合推理机。

Finally, the diagnosis results are achieved through forward chaining method.

最后, 根据应用正向推理机得到磨损故障的诊断结果.

The system adopts the forward and backward chaining, researches the reasoning under uncertainty and inexact reasoning;

提出对系统采用交互式知识获取途径、双向推理控制策略，对不精确推理和不确定性推理的传播算法作了一定的研究，成功地将其应用到马铃薯专家系统的构建之中；
