Simulation of the logistic process of the industrial enterprise evacuation in wartime

The complex problem of a multicriteria nature that is related to the justification of the new location for the evacuated enterprise is stated and solved. The simulation of the logistic process of evacuation in the conditions of threats and vulnerabilities of wartime is carried out. The relevance of the study is related to the justification of the possible location of the industrial enterprise production, considering the process of technological equipment transportation to the rear in a heterogeneous transport network. Also, the processes of moving the evacuated industrial enterprise to a new location and establishing the production in the new place are studied. The study simulates the logistical process of industrial enterprise evacuation in terms of wartime threats and vulnerabilities. A method to justify the location of the evacuated industrial enterprise that is based on a multivariate analysis with the use of qualitative expert assessments in the form of linguistic variables values is proposed. The complex dynamics of military cargo and technological equipment delivery to the new location are considered. This is done by means of simulation modeling that considers the specifics of a heterogeneous transport network and the risks and threats of wartime. An agent-based simulation model of the logistical process of the industrial enterprise evacuation has been developed. A new algorithm to minimize the delivery time of cargo and technological equipment that considers possible risks and threats and makes it possible to find the optimal route in a heterogeneous transport network is presented. An optimization model to locate the technological equipment of the evacuated industrial enterprise in the new territory, considering the criteria of time, cost and risks has been created. The multi-criteria optimization of the technological equipment location was carried out under the conditions of conflicting criteria, considering the requirements of wartime. The scientific novelty of the study is related to the development of methods and models of the industrial enterprise evacuation process based on agent-based simulation modeling, integer (Boolean) optimization, expert evaluation, use of linguistic variables that ultimately makes possible to justify the logistics of industrial enterprise evacuation in wartime. The results of the study should be used to plan the evacuation process of the industrial enterprise considering the requirements of wartime.
