Study On The Method Of Defending Formation Based On Flow Interception Location Model

Defensive combat in fortified positions centered on permanent fortifications,whose mode of operations is usually based on inferior forces against enemy attacks,is one of the basic types of defensive combat of positions.Through the establishment of positional system which are locally centralized,point-based,and deep-echelon,defensive combat in fortified positions will deplete a large number of enemies and pin the enemies down to buy time and create conditions for transferring to offensive status or assaulting in other directions.And a good configuration technology of defensive positions can not only improve the operational effectiveness of defensive positions,but also improve the accuracy and automation of defensive operations planning.Therefore,the research on the configuration technology of defensive positions is of great theoretical and practical significance for improving the operational effectiveness of defensive combat in fortified positions in a dynamic and complex battlefield and for optimizing the utilization and configuration of firepower resources in the defensive positions.Based on the realistic offensive and defensive scenarios under static and dynamic conditions,this dissertation aims to solve the key technical problems in the selection and adjustment of realistic defensive positions.Based on the system modeling and formalization of defensive positions,this work mainly studies the theory and method of selecting and adjusting the defensive positions under the static and dynamic conditions.The main contributions and innovations of this paper are as follows.1.In order to select a set of scientific influencing factors of defensive position,a formal modeling method based on the flow Inception location-allocation model was proposed.According to the influential factors of spatial location selection and the characteristics of military engineering,this paper summarizes ten influential indicators of military,economic and environmental factors,and uses AHP(Analytic Hierarchy Process)to select some factors which have the most important influence on the configuration model of static defensive positions.We analyze in depth the characteristics and purpose of the configuration of defensive positions.According to the selected factors,a formalized model of configuration problems of static defensive positions based the flow Inception location-allocation model is established.Based on the Lanchester combat effectiveness equation,we propose three methods of quantitative calculation of combat effectiveness in positions from the known information integrity degree of enemies and the efficiency of node partial order.2.By analyzing the defensive formation configuration task profiles under dynamic conditions,a formalized model of dynamic defensive formation adjustment based on emergency logistics location model was established.Under the background of modern control system theory,based on the previous configuration model of static defensive formation and the task connotation of dynamic operational force adjustment,this paper puts forward a set of dynamic and robust,Economic and military as one of the dynamic defensive formation configuration modeling framework.In addition,a quantitative description of the various uncertainties that exist in dynamic tasks provides a more formally expressed dynamic defensive position adjustment model.3.From both coding and constraint digestion,this paper proposes a static defense matrix configuration method based on NSGA2 algorithm using simulated annealing mechanism.Aiming at the connotation of static defensive formations,based on the ADC method of traditional systematic evaluation method,an evaluation index of formations under completely known,partially known and completely unknown information integrity is proposed.Faced with the problem of the configuration of the static defense formation,the branch defense and the improved NSGA2 algorithm are respectively used to solve the problem of the configuration of the static defense formation.The performance analysis shows that the latter overcomes the shortcoming that the algorithm search easily falls into the local optimum.This paper proposed two evaluation indexes which were the overall performance evaluation and the robust performance evaluation of the operational effectiveness of the formation.Based on the traditional ADC method,three kinds of intelligence integrity of known enemy information,known part of enemy information and unknown enemy information were designed Case of evaluation index solution.The experimental analysis of multiple battlefield topology models transformed from the actual battlefield topography shows that the overall evaluation index and the robust evaluation index of the solution prior to screening are both above 5%.4.Aiming at the dynamic configuration model of the system,a robust optimal solution to the dynamic defensive formation adjustment based on optimal control is proposed.The robust stability analysis of the algorithm is also given.Based on the operational background of the dynamic defensive formation configuration,based on the tasks of dynamic defensive formation mission and the method of dynamic defensive array configuration,we prove the system robustness and stability in detail.Finally,the validity and stability of the algorithm are verified by the relevant examples.The final degree of complementarity is 97.88%,and the goal of fully recovering the fighting force of each receiving end is reached basically.The system is in uniform distribution disturbance and normal distribution disturbance under the stability of all,reflects the applicability and effectiveness of the algorithm to solve this.
