Problems solved by technology

However, due to the lack of population diversity, the particle swarm optimization algorithm is prone to "premature" phenomenon, and it is easy to fall into the disadvantage of local extreme points in the later stage of the algorithm.

Embodiment Construction

[0034] Such as figure 1 As shown, the automatic pharmacy storage allocation optimization method based on the improved chaotic particle swarm algorithm of the present invention comprises the following steps:

[0035]A: Establish a model of the pharmacy’s drug store; suppose the drug store in the storage area has m layers and n columns, and the column closest to the medicine entrance is recorded as the first column, and the bottom layer is recorded as the first layer, and the column in the i-th layer and the j column The storage position is recorded as (i,j), (i=1,2,...,m;j=1,2,...n), and the position of the storage entrance is recorded as (0,0); for each When encoding a storage location, code the storage location at the i-th column j layer as (i-1)m+j; arrange the storage location codes from small to large to form a one-dimensional array; when a certain storage location is stored in goods , the corresponding element in the array is recorded as 1, and the storage location is re...

Abstract

The invention discloses an automatic pharmacy storage location optimizing method based on the improved chaos particle swarm algorithm. The method comprises the following steps of A establishing a pharmacy drug storeroom model; B, randomly initializing the position and speed of each particle in population; C, evaluating the adaptability of each particle in the initial population, and storing an overall optimal position and an individual optimal position; D, updating the speed and position of each particle, and adopting a self-adaptive inertia coefficient to update the weight; E, evaluating the adaptability of each particle after being updated, and storing the overall optimal position and individual optimal position; f, executing the chaos local search for the optimal particle in the population, and updating the overall optimal position and individual optimal position; G, judging whether a maximal iteration number is achieved or not, outputting a calculation result - the optimal distribution strategy of storage location if the maximal iteration number is achieved; and returning to the step D if the maximal iteration number is not achieved. By adopting the method, efficiency of a pharmacy intelligent storage system can be effectively improved, and the dense storage can be realized.

Description

technical field [0001] The invention relates to a method for optimizing the allocation of pharmacy storage positions, in particular to an optimization method for automatic pharmacy storage allocation based on an improved chaotic particle swarm algorithm. Background technique [0002] The working efficiency of the automated pharmacy intelligent access system mainly depends on the distribution strategy of the warehouse area and storage space. A reasonable storage layout and storage space allocation strategy can greatly improve the storage efficiency of the warehouse and reduce useless consumption. It is also the modernization management of the pharmacy. , An important guarantee for improving the functions of the pharmacy, which has important practical significance for shortening the prescription processing time, reducing the cost of drug handling and storage, reducing the loss of drugs in the process of storage and handling, and improving the profit of the pharmacy.
