Abstract
A logistics distribution path optimization method based on soft time windows and hill climbing genetic algorithms is proposed to reduce costs and achieve low-carbon transport. Experimental results show the improved algorithm converges after 20 iterations with a fitness of 4.93×10⁵, lower than others. It averages 20 iterations and 3.1 seconds, indicating high efficiency. In example C105, the path length is 843.70 km, below others. In a practical test with a chain supermarket, the delivery path length is 367.5 km, reduced by at least 14.9%. Total cost is 1873.6 yuan and carbon emissions are 109.1 kg, both lower. Vehicle load capacity exceeds 80%, improving utilization. Under multiple distribution centers, delivery time is shorter and demand coverage averages 96.5%, better than others. The algorithm effectively reduces costs, emissions, and enhances efficiency, with high application value.
With the rapid advancement of agricultural modernization and the increasing demand for agricultural products, inefficient logistics distribution has become a major bottleneck in rural supply chains. This study addresses the capacitated vehicle routing problem (CVRP) in agricultural logistics. A genetic algorithm (GA)-b...

For the recycling of waste power batteries, a multi-depot soft-time-window vehicle routing problem model was established to minimize fixed costs, transportation costs, and time-window penalty costs. An improved genetic algorithm was designed that integrates adaptive crossover/mutation with 2-opt local search. Compared...

Timely delivery is the core goal of logistics business and directly affects customer satisfaction and loyalty. However, uncertain factors such as road damage, traffic congestion and traffic accidents often make it impossible to deliver on time by the shortest path. To this end, this paper proposes a path optimization a...
