基于效率优先的装卸力量分配建模与仿真

Modeling and Simulation of Loading and Unloading Force Distribution based on Efficiency Optimization

为提高战时军事物流的物资装卸效率,通过数学建模和仿真分析,提出一种装卸力量分配模型及其能力提升策略。以弹药单元的机械化搬运装载为例,对过程影响因素做出基本假定,通过案例分析推导,构建装卸力量分配模型,并提出末端瓶颈时间的概念;通过模型分析并结合部队现状,提出有效可行的装卸能力提升策略;最后应用Matlab进行实例仿真分析,检验模型的可行性。实例仿真结果表明,当装卸力量充足时装卸效率主要取决于末端瓶颈时间,装卸力量不足时搬运机械的行驶速度、装卸货用时是效率的主要影响因素,战时的装卸保障能力需要通过系统的实战化训练来生成。

In order to improve the material handling efficiency of military logistics in wartime,a handling and unloading force distribution model and its capacity promotion strategy are proposed through mathematical modeling and simulation analysis in this paper.Firstly,it makes the basic assumptions of the process influencing factors by taking the mechanized handling and loading of ammunition unit as an example.Secondly,it constructs the loading and unloading force distribution model through case analysis and derivation,and proposes the concept of end bottleneck time.Thirdly,it proposes an effective and feasible strategy to improve the handling capacity through model analysis and combined with the current situation of the army.Finally,it tests the feasibility of the model by Matlab simulation.The simulation results show that when the loading and unloading force is sufficient,the unloading efficiency mainly depends on the terminal bottleneck time;when the loading and unloading force is insufficient,the travel speed of the handling machinery and the loading and unloading time are the main factors affecting the efficiency.The loading and unloading support ability in wartime needs to be generated through systematic practical training.
