Abstract

The invention provides a harmony search algorithm for solving the mixed packing of multi-variety and large-batch cold chain items. First, various parameters of the cold chain items to be transported and the single-temperature zone refrigerated vehicles used are obtained, and different cold chain items are assembled to a single The mixed model of the refrigerated vehicle in the temperature zone, and then establish the initial harmony memory, use the random search algorithm to obtain the initial solution, and then repair the solution through the repair operator until the required number of solution vectors is obtained; secondly, according to the parameters and sum The rules of acoustic search calculate new solutions and repair them, and finally get the mixed packing scheme of cold chain items that meets the conditions. The invention can use the harmony search algorithm to automatically calculate and generate the minimum humidity difference, shelf life difference and mixed type difference under the condition of satisfying the temperature constraint, volume constraint and weight constraint of the refrigerated vehicle in a single temperature zone. Target configuration.

Description

technical field [0001] The invention relates to the field of cold chain logistics, in particular to a harmony search algorithm for solving the mixed packing of multi-variety and large-batch cold chain items. Background technique [0002] In some scenarios of logistics and supply chain management, it is a complex decision-making process to formulate a mixed packing plan for multi-variety and high-volume items. Take the cold chain transportation of food as an example. Because some fruits emit ethylene or emit a strong smell, while other fruits will be ripened by ethylene or can absorb odors, these two types of fruits should not be mixed. In addition, when the capacity of refrigerated vehicles is limited, not only the capacity of the compartments, but also factors such as temperature, humidity and shelf life of food in the transportation environment must be considered. Therefore, designing a reasonable assembly scheme not only helps to improve transportation efficiency, but al...
