Semi-Open Multi-Distribution Center Path Planning with Time Windows

A well-planned robot dispatching platform reduces costs and increases efficiency for companies while also reducing carbon emissions achieving sustainable development. At the moment, solution to difficulty of warehouse logistics is use multiple distribution centers with autonomous mobile robots (AMR). To solve this problem, paper establishes a semi-closed model centers, considering number cycles vehicles. An improved ant colony algorithm proposed improve heuristic function based on node distance relationship quality path search. Dynamic variable pheromone concentration volatility factors are set accelerate convergence speed effectively problem premature algorithm. The traditional used established model. In addition, results show that has certain rate dominance in single-day cost closed model, but overall comprehensive lower than semi-open multi-distribution center 7 day average reduced by 12%. can save about 119 kWh electricity under same target volume requirement, which achieves company’s goals reduction increased efficiency, as well green
