侦查破案论

侦查破案概念应当从行为、认知、结果等3个角度进行界定。破案条件规定应当从侦查措施及 强制措施采取的合理性根据维度进行理解,即有关侦查措施和强制措施只有在案件事实调查、证据收集以及 犯罪嫌疑人确定程度等方面达到一定标准时方可以采取。破案的思维方法包括经验方法和逻辑方法两类。 破案的行为方法主要包括巡逻发现、物证分析、重点排查、秘密侦查、诱惑侦查等5种基本类型。

A Signed Digraphs Based Method for Detecting Inherently Unsafe Factors of Chemical Process at Conceptual Design Stage

Digraph-based causal models have been widely used to model the cause and effect behavior of process systems. Signed digraphs （SDG） capture the direction of the effect. It should be mentioned that there are loops in SDG generated from chemical process. From the point of the inherent operability, the worst unsafe factor is the SDG having positive loops that means any disturbance occurring within the loop will propagate through the nodes one by one and are amplified gradually, so the system may lose control, which may lead to an accident. So finding the positive loops in a SDG and treating these unsafe factors in a proper manner can improve the inherent safety of a chemical process. This article proposed a method that can detect the above-mentioned unsafe factors in the proc- ess conceptual design stage automatically through the analysis of the SDG generated from the chemical process. A case study is illustrated to show the working of the algorithm, and then a complicated case from industry is studied to depict the effectiveness of the proposed algorithm.
