Abstract

The invention relates to the technical field of production safety management, and provides a production process change risk assessment method. The method comprises the following steps: obtaining production process change items, a set composed of the production process change items belonging to a subset of a set composed of a plurality of preset risk factors; performing assignment on the index coefficient of the risk factor according to the production process change project; according to the index coefficient of the risk factor and the weight of the risk factor, calculating the production process change risk value of the production process change project, and obtaining the weight of the risk factor through pre-calculation; and evaluating the production process change risk level of the production process change project according to the production process change risk value of the production process change project. According to the technical scheme provided by the invention, automatic and accurate quantitative evaluation can be carried out on the change risk of the production process, so that the production management and control quality is improved.

Description

technical field [0001] The invention relates to the technical field of production safety management, in particular to a production process change risk assessment method and a production process change risk assessment system. Background technique [0002] The production process change is mainly aimed at the adjustment of the products involved in the chemical production process, process-related indicators, processes, technical parameters, and operating regulations. Inappropriate changes will cause potential safety accidents, so it is necessary to identify and manage the risks brought about by changes in production processes, so as to prevent and control potential accidents. [0003] Existing production process changes are recorded using pre-made safety checklists, and change risk assessments are performed manually. Obviously, this purely manual operation method makes the final evaluation result completely dependent on the experience of the evaluator, resulting in inaccurate e...
