Microscopic simulation method for matching wharf stockpiling volume and berthing capability

Abstract

The invention belongs to the field of transportation station planning, design and management, and aims to create a behavioral simulation model of mutual linkage of wharf stockpiling volume and berthing capability and research positive and negative influences of stockpiling volume planning of a wharf storage yard on actual wharf loading and unloading efficiency and actual wharf cargo handling capacity so as to acquire a realistic internal nonlinear causal relationship to search a reasonable matching method for the wharf stockpiling volume and the berthing capability. The technical scheme includes that a microscopic simulation method for matching the wharf stockpiling volume and the berthing capability includes the following steps of cellular selection, operation of a cellular automation, establishment of a basic frame of a microscopic simulation frame for matching of the wharf stockpiling volume and the berthing capability, cargo congregation, cargo evacuation and establishment of evaluation indexes, a port road traffic volume forecast module, a port road network module, a container terminal storage yard module, a shipside shipment module and a shipside unloading module. The microscopic simulation method is mainly applied to the transportation station planning, design and management.

Description

technical field [0001] The invention belongs to the technical field of transportation station planning, design and management, and specifically relates to a cellular automaton microscopic simulation method for matching wharf storage capacity and berthing capacity. technical background [0002] The wharf yard is the basic element to ensure the loading and unloading operations of the wharf ships, and is the key node of the wharf collection and distribution operations. Regardless of technology or economy, a wharf with a certain berthing capacity must have a matching storage yard with a certain capacity. Whether the two can match directly determines the actual efficiency of wharf loading and unloading operations, and the actual throughput of the wharf. Whether the port can establish an efficient collection and distribution system, whether the terminal company can have good economic and social benefits, so the matching of the two is the port planning layout and optimal design, th...

However, this type of macro simulation software is not a multi-agent simulation, and cannot describe its complex nonlinear behavior. The conclusions obtained cannot be close to the actual situation, and the accuracy of the results cannot be guaranteed.

The third is to establish a microscopic simulation model, so far there is no

[0005] (1) Many literatures study the berth capacity of the terminal alone, or the layout of the storage yard to improve the operation efficiency of the entire terminal, and consider the two comprehensively, especially based on the berthing capacity of the terminal to match it There are few studies on terminal storage capacity

[0006] (2) Most of the current studies on the matching of wharf storage capacity and berthing capacity remain at the stage of theoretical exploration. Some studies use the establishment of an
