Abstract
The problem of route optimization of large volume and long distance material distribution is carried out from the rear strategic logistics center to the front line distribution center, researched by turning into multimodal transport problems, and a single-path multimodal transport path optimization model is established. Decision variables about stage safety probability are introduced; the nonlinear model is simplified into a second-order programming model, by changing the probability of task safety and simplified the model to a linear programming model by using the monotonicity of logarithmic functions. An example is presented to solve the simulation with LINGO software, made a reference plan under different constraints, the correctness of the model is verified.
Highlights
Logistics distribution is the important content of military traffic transport, is shouldering the important combat goods delivery to combat troop’s task, and it is the link that transforms logistics support into operational capability

There is little research on multimodal military transport at home and abroad at present, Xi-rui Yang based on Lagrangian relaxation method, decomposed the problem of multimodal military transport into two sub-problems: cargo flow and vehicle flow, the two subproblems are solved separately; Jiaying Zhang has set up a multimodal military transport model, which take time and cost as the target, and time and capacity as constraints, and solved the problem by Genetic algorithm and Matlab software
Summary
Logistics distribution is the important content of military traffic transport, is shouldering the important combat goods delivery to combat troop’s task, and it is the link that transforms logistics support into operational capability. Under large-scale combat conditions, military transport are the characteristics of great material consumption, the transport mission is large, the transport scope is wide, and the tasks have a variety of forms; The timeliness of transport is high and the persistent requirements high, the transport environment is poor and the hidden defense is difficult. It is difficult to improve the coordination of military transport organization, the requirement of the loading and unloading and the plan of transportation guarantee. The paper studied the problem of route optimization of railway, highway, waterway and aviation in the context of large-scale operation, a scientific and rational path optimization model is established, by reasonable selecting the running line and transport tools, accurate and efficient delivery plan can be developed
