A method for planning and utilization of bulk cargo terminal yard based on knowledge reasoning

Abstract

The invention discloses a method for planning and utilizing a storage yard of a bulk cargo terminal based on knowledge reasoning, which includes using a hierarchical screening method to obtain the optimal storage area and belt path of the cargo, and the hierarchical screening includes the following steps: S1. Obtain cargo information; S2, allocatable area reasoning; S3, available space sorting; S4, equipment and yard reasoning; S5, optimal path reasoning. The patent of the present invention provides a dry bulk terminal yard planning and utilization method based on knowledge reasoning. Taking the dry bulk cargo terminal yard as the research object, it can quickly and accurately find a suitable yard planning and utilization method based on knowledge reasoning. Based on the combination of knowledge rules and considering the global optimal belt path, after each set of judgments, a part of the data is filtered out, the selectable area of ​​each layer is gradually reduced, and finally the optimal storage area and belt path are screened out based on the optimal algorithm , which is more scientific and objective than manual analysis, and the judgment is more accurate and precise.

Description

technical field [0001] The invention relates to the technical field of cargo distribution in bulk cargo terminal yards, in particular to a method for planning and utilization of bulk cargo terminal yards based on knowledge reasoning. Background technique [0002] As a buffer area for the transshipment of dry bulk cargo terminals, the yard is a limited resource for all terminals. The yard plays an important role in the transportation of the terminal. The planning and utilization efficiency of the yard greatly affects the overall speed of the loading and unloading ships. One of the key factors of the wharf's service capacity is how to effectively utilize the wharf yard under the existing conditions, provide a reasonable storage yard planning and utilization plan for the cargo, and improve the wharf turnover efficiency, which is a very important topic. Among them, the methods used for the planning and utilization of bulk cargo terminal yard mainly include: [0003] 1. Allocati...

Problems solved by technology

[0005] As far as the above two existing methods are concerned, the allocation strategy based on artificial experience is too dependent on past work experience, which may be relatively simple; in addition, artificial experience relies on perceptual knowledge, which is difficult to quantify, and there is room for optimization and improvement. Smaller, less intelligent, time-consuming, labor-intensive, and less stable; on the one hand, the random stacking strategy may lead to relatively scattered stacking of goods, which is not conducive to the subsequent turnover of goods and the utilization rate of the yard is low. In addition, it only considers Although it meets the stacking requirements, it is not necessarily the optimal choice, and the equipment operation path cannot be guaranteed to be the optimal path, which should also affect the turnover efficiency of the goods to a certain extent.
