A Strong Relevant Logic Based Computational Model For Emergency Improvisation Decision

Emergency Improvisation Decision is a cognitive psychology determinationprocess that decision makers analysis, judgment, forecast and reasoning to emergencysituation rely on their knowledge, experience and skills, in which the psychologymodels include emergency decision sharing mental model and decision cognitiveprocess model. The effective way of dealing with the less experienced emergencydecision makers is that how to construct the computational model of the cognitiveprocess of emergency improvisation, how to realize the partialautomation of thiscognitive process in the field of computational science. The realization ofpartialautomation is need to research the computational model of sharing mentalmodel, the computational model of emergency improvisation cognitive process andthe cognitive reasoning based on the specific logical basis. This dissertationperformed a deep research on the three key problems in emergency improvisationdecision computational model, including emergency improvisation decision cognitionprocess and cognition operations, emergency knowledge representation, and the logicfunduction of the decision-making cognition reasoning. Following work has beenachieved:1. Emergency improvisation decision cognition process model wasproposed. Based on the research of the decision cognition process of theexperienced decision makers, it has designed a conceptual model ofimprovisation decision cognition process. The model has four layers,including emergency cognitive operation layer, emergency cognitivefunction layers, cognitive process operaton layer and cognitive proceeatomic operation layer. Based on emergency knowledge in emergencyplan, the dissertation described emergency cognitive operators set.Classfing the emergency cognitive operators in terms of the emergencyevent awareness, it put forward emergency cognitive functions set.Cognitive operators were proposed depending on the SensemakingModel of natural decision cognitive. At last, it desribed cognitive proceeatomic operators set.2. The conceptual model of emergency sharing mental model was proposed.First, the dissertation proposed the framework of emergency sharingmental model. Adopting the method of top-down, emergency sharing metal model was built base on the ABC Ontology Model, including eventawareness atomic ontology model as the upper ontology, emergencyevent awareness ontology model as middle otology. Domain ontologyincludes emergency situation ontology model, emergency resourceontology model, emergency case ontology model, emergency planontology model and emergency organization ontology model.3. Improvisation decision strong relevant logic model was designed. Inorder to meet the need of decision cognition reasoning, the improvisationdecision strong relevant logic model was proposed, including logicreasoning module and logic representation module. Event logic and statelogic were introduced to the improvisation decision strong relevant logicand extended emergency domain logic operators and theorems.Emergency improvisation decision cognition process was representedthrough defining the cognitive process atomic operation.Finally, an emergency improvisation decision computational model realizationbased on above research was introduced to verify our results, including the calculationmodel realization framework, the knowledge representation method of decisioncalculation, and evaluation standard. At last, we selected a representative casefragments, compared the calculation results of computational model and the casedescription, and evaluated the flexibility and efficiency of the model.
