Abstract
Analyzing the emergency response process and time characteristics after aircraft fires is extremely important for airport safety. Due to nonprocess-related elements, the Petri net model of the emergency process is generally complex and difficult to revise and expand. In this study, the actantial model was used to analyze the semantic structure of emergency actions in the Petri net emergency process model, and the actantial-timed Petri net (A-TPN) hybrid model was proposed for problem solving. The emergency response process of aircraft fires was analyzed as a case study to explain the application steps of the A-TPN hybrid model. First, the types of elements should be divided into process-related elements and nonprocess-related elements. Process-related elements include status elements and narrative elements, which are equivalent to the places and transitions in the Petri net model. Second, the workflow constructed by the status and narrative elements is converted into a Petri net. An actantial model is used to analyze the semantic structure of emergency response action narratives. Third, according to the analysis of the actants of the helper and the opponent, emergency action time characteristics are considered to construct the A-TPN hybrid model and analyze the time performance of the emergency response process. In this way, an emergency response plan can be analyzed and promoted for smart development.
Highlights
Aircraft fires are one of the most common types of fatal accidents in civil aviation, and they can be caused by system failures or crash accidents
The emergency response process for aircraft fires can be viewed as a workflow, which is important to support emergency decision makers to effectively respond to emergencies [1, 2]
The actantial model was used to reconstruct the workflow model for the emergency response process, which contains key emergency actions based on an airport emergency rescue plan
Summary
Aircraft fires are one of the most common types of fatal accidents in civil aviation, and they can be caused by system failures or crash accidents. The mathematical analysis tools of Petri nets emphasize the accuracy of formal description to ensure the semantic clarity of each process element; in emergency response problems, emergency actions are affected by complex conditions. It is more difficult for process language to express such an influence than it is for process language to express functions. This paper analyzes the semantic connotation of elements to simplify the Petri net model for the emergency response process and uses an aircraft fire emergency response as an example to analyze the steps of establishing the actantial-timed Petri net (A-TPN) hybrid model.
