Problems solved by technology

The heuristic priority coefficient and the empirical coefficient have a great influence on the solution of the problem. If the weight of each node is not properly selected, it is easy to fall into a local optimum or reduce the convergence speed, which greatly affects the accuracy and efficiency of the algorithm. In extreme cases will be as efficient as an exhaustive search

Embodiment Construction

[0043] According to the growth characteristics of vegetable stubble in different seasons and different regions, the present invention analyzes the influence of planting mode (spreading, spot planting, planting, etc.), season, region, vegetable variety and planting facilities (greenhouse, open field, etc.) on vegetable quality. And on the basis of various constraints, with the optimization goal of minimizing the number of vegetable stubbles and maximizing land productivity, an optimal mathematical model for the arrangement of vegetable stubbles was established, and a variable heuristic priority coefficient ant colony The optimization algorithm solves the model. Such as figure 1 A flowchart of the method is shown.

[0044] The method includes:

[0045] S1. Map all vegetable crops to n nodes one by one, and establish a mathematical model. The objective function is:

[0046] p = k 1 ...

Abstract

The invention provides a method for optimizing arrangement of crop rotation in vegetable planting. The method includes: mapping all vegetable crops as n nodes in one-to-one correspondence and establishing a mathematical model; solving the model by ant colony optimization with variable inspired preferred numbers, and outputting an optimal path which is an arrangement path for vegetable crop rotation. By applying the method, informationized and automatic crop rotation arrangement for vegetable planting can be realized, labor intensity is lowered for production arrangers, overall quality and economic benefit of vegetables can be improved, and soil fertility, land productivity and labor utilization rate can be kept maximally.

Description

technical field [0001] The invention relates to the field of vegetable production arrangement, in particular to an intelligent optimization method for vegetable planting stubble arrangement. Background technique [0002] In the past, the vegetable planting stubble arrangement plan was completely compiled manually based on personal experience, but vegetable planting has the characteristics of long production cycle, many constraints, and fixed production methods, so the preparation of vegetable production scheduling plan has become a cumbersome and demanding production experience. Manually compiled plans often fail to take into account the requirements of efficiency, production capacity, cost savings, geography, planting facilities, and reasonable planting models. Therefore, it is necessary to find an intelligent optimization method to realize online automatic preparation of production scheduling plan. [0003] We use mathematical modeling to map the vegetable production plan...
