Structural Optimization of Logistics Distribution System Based on Characteristic State Space

Abstract

In this paper, resource flow variables are extracted from the internal structural features of the logistics distribution process and a new method for optimizing the internal structure of the logistics distribution system by using the characteristic state space is proposed. The characteristic state equation is constructed to represent the input and output resources of each basic logistics activity. The basic logistics activity equation is iterated according to the resource flow, and the implementation of the basic logistics process is visually and quantitatively expressed in the form of the characteristic state matrix. According to the nature of the characteristic state space, the optimization problem of the logistics distribution system is transformed into a critical path-planning problem, the gradient calculation of the objective function is solved, and an improved genetic algorithm is proposed. This accelerates the convergence speed of the algorithm and reduces the running time of the optimization process. Taking a listed logistics distribution enterprise as an example, the optimization algorithm is verified, which proves the advantages of the algorithm and provides a new method and theoretical basis for the analysis and optimization of the logistics distribution system.

Optimization of AGV Sorting Systems in Pharmaceutical Distribution: A Two-Stage Package Assignment and Simulation Approach

“…Although these methods are innovative in their specific contexts, none addresses the simultaneous optimization of package assignment with AGV routing, which is critical in environments where the coordination of multiple logistics operations can significantly impact overall system efficiency. while Bao et al [2] proposed a logistics distribution system optimization. Liu et al [19] developed a multiobjective model for AGV scheduling in warehouses, two adaptive genetic algorithms (GE) and a proposed multi-adaptive genetic algorithm (MAGA) are applied to optimize the model.…”

Logistics Efficiency in Product Distribution with Genetic Algorithms for Optimal Routes

“…Genetic algorithms are used to find optimal delivery routes by considering the distance traveled, transportation costs, travel time, and route effectiveness. Examples of applications of genetic algorithms in optimizing product distribution routes include optimizing airport shuttle bus routes, optimizing logistics distribution routes, and determining vehicle delivery routes [32][33] [34]. With its ability to find solutions that are close to optimal in a complex search space, genetic algorithms are an effective method for solving product distribution route optimization problems.…”
