A Parallel Logistic Network Simulation Method and System to Improve Logistics Efficiency

Abstract

In order to solve the problems of package delivery delay and package loss caused by the sudden increase of package transportation demand during large-scale promotion activities such as 11.11 and 6.18, this paper proposes a parallel logistic network method, aiming at the logistic network of large logistic enterprises, establishes its equivalent virtual logistic network, senses the package transportation demand and network state of the actual logistic network, circularly simulates the operation in advance, finds the delayed and lost packages, analyzes the reasons, and adjust the parameters of network nodes and transportation lines to ensure that packages are delivered on time at low cost. Then the adjusted virtual network parameters are fed back to the actual logistic network, so as to realize the efficient operation of logistic enterprises. A simulation engine ensures that the simulation of 400 million package distribution in 30 days can be completed in half an hour on a personal computer. The application results show that the parallel logistic network reduces the package transportation time by about 10%. The transportation distance is reduced by 7%. Reduce transportation costs by 15%.
