A joint scheduling simulation and analysis method for multi-line parallel ship locks

Abstract

The invention discloses a multi-line parallel ship lock joint scheduling simulation and analysis method, comprising the following steps: 1. determining the initial conditions of the ship lock joint scheduling simulation; 2. determining the navigation route and the position of the potential conflict area; Establish a mathematical model of fleet movement; analyze the operational efficiency of the five ship locks and the traffic conditions in the conflict zone. The invention regards ship lock dispatching as the operation problem of two objects, ship lock and ship, and constructs a mathematical model of ship lock operation state and a mathematical model of fleet movement. When analyzing the operation status of parallel ship locks and the traffic conditions in navigation conflict areas, it is possible to calculate and analyze the mutual influence between locks, locks and ships, and ships and ships during the joint dispatching process of multi-line parallel ship locks. The traffic organization in provides a reliable reference.

Description

technical field [0001] The invention belongs to the field of water transportation, in particular to a simulation model of ship lock traffic organization. Background technique [0002] Ship lock is a kind of navigation facility widely used in cascade channelization projects of natural rivers. It has played an important role in promoting the upgrading of inland waterways in my country and ensuring the smooth progress of the construction of high-level waterway networks. In the past, due to the constraints of channel conditions, the inland river freight volume was small, and most of the hub constructions were single-line ship locks. There were few double-line and multi-line parallel ship locks, and the layout was mostly independent. For example, the three ship locks of Gezhouba were arranged separately, and No. 1 ship lock was located on the right bank of the river. , No. 2 ship lock is located on the right bank of the Sanjiang River, and No. 3 ship lock is located on the left b...

AI Technical Summary

Problems solved by technology

However, in the previous studies, due to the simple traffic flow of the lock, more attention was paid to the block problem of the lock chamber, and little attention was paid to the multi-level scheduling of multi-line parallel locks, let alone the traffic flow conflict near the lock.

At the same time, in the previous ship lock traffic organization simulation, the method based on the event process was generally adopted. The ship dispatching process and the ship lock operation process were included in one model at the same time. The model system was complex, which also increased the work of model debugging and modification difficulty
