Described boats and ships generation module generates boats and ships according to Vessels arrival rule matching normal distribution.
Carry out detailed step with instantiation below to illustrate:
Step one, data collection and statistics: gather the data of 2010-2013 Three Gorges Pivot Project navigation boats and ships, and add up each year
The type of boats and ships, quantity, tonnage and accounting.
Step 2, Three Gorges Pivot Project boats and ships Study on Simulation Model
2.1, boats and ships behavior model: owing to Three Gorges Description of Ship is various, though the ship running of the most shipmate type in same class boats and ships
Speed is the most different, largely adds the complexity of modeling.Boats and ships uplink/downlink headway is regarded identical in this model,
The time that various ships crosses Three Gorges Ship Lock is the most identical.
2.2, ship lock service model: Three Gorges Ship Lock is double-line five-grade ship lock, uses one-way transit mode, and general implementation north line is up,
South line is descending, and the time that up-downgoing spends is essentially identical.Under design condition, descending boats and ships are from entering first order ship lock to rolling the away from
Five-level ship lock needs about 3.5h altogether；Gezhouba Shiplock is " two line three locks " structure, and 1, No. 2 ship lock can be by large ship or big
Type fleet, about 1 h of each lockage time；No. 3 ship lock are mainly by below 3000t combination vessel and local flotilla, often
Secondary lockage time about 40min.Ship lift, as the accessory channel of Three Gorges Pivot Project, can pass through below 3000t ship in addition to dangerous materials
Oceangoing ship, the time about 40min needed for unidirectional single.
2.3, boats and ships organizational scheduling model: simulation of ship is divided into passenger boat, Commercial Vehicle roll-on-roll-off ship, container ship, danger by this model
The six class boats and ships such as product ship, Bulk Cargo Ship, other boats and ships, in the lockage order arranging various ships, passenger boat belongs to priority
High, Commercial Vehicle roll-on-roll-off ship takes second place, and third, reason is all that the surcharge of boat-carrying commodity is higher to container ship, lockage etc.
Treat that overlong time can cause the loss that shipowner is bigger；Then it is exactly Bulk Cargo Ship and other boats and ships.Wherein dangerous goods shipping can only
Individually lockage, it is impossible to other any boats and ships mixing lockages；Similar boats and ships are according to arriving first the principle first crossed.
Step 3, the systematic analysis of simulation modeling
3.1, system boundary sets: in this research emphasis analysis system, boats and ships overstock situation, and analyzed area is the anchorage around two dams
Region between region and two dams, wherein the anchorage offset dam about 10km of Three Gorges Dam upstream, the anchorage of Gezhouba down-stream
The about 9km away from Ge Zhou Ba.The present embodiment phantom sets upstream boundary as Three Gorges Dam upstream report line, and downstream boundary is Ge Zhou
Report line under dam.
3.2, system flow analysis: behind the origin and destination of clear and definite analogue system, needs the operational process of grasp macroscopical boats and ships, this emulation
System is divided into up and descending two systems.The descending system that enters from Ba Shang anchorage, Three Gorges, then by Three Gorges Ship Lock or liter ship
Machine enters Gezhouba Reservoir Region, then leaves system by Gezhouba Shiplock, and up boats and ships are contrary with up flow process.Three Gorges Pivot Project
The overall procedure of vessel motion is shown in accompanying drawing 1.
3.3, system simulation platform: select Arena software as the platform of Three Gorges vessel traffic flow analogue system.
3.4, the input/output of model parameter:
Table 1 simulation system parameters table
Step 4, the foundation of phantom
4.1, input module:
Boats and ships generate the beginning that submodel is whole model, according to arriving anchorage under Ba Shang anchorage, Three Gorges and Ge Zhou Ba actual every day
Data, this modeling generates boats and ships, and the boats and ships of generation sequentially enter system, are left after Gezhouba Shiplock by Three Gorges Ship Lock
System.In order to make simulation result with practical situation relatively, to boats and ships arrival interval natural law according to Poisson distribution, normal distribution
Equal distribution is fitted (365 ship lockage data in 2013 that the initial data of matching comes from collection), and fitting result is such as
Shown in following table:
Table 2 Vessels arrival rule matching table
| Distribution title | Standard deviation |
| Normal distribution | 0.0328 |
| Beta is distributed | 0.0565 |
| Poisson distribution | 0.0593 |
| It is uniformly distributed | 0.0639 |
| Exponential | 0.128 |
| Angular distribution | 0.128 |
| Weibull distribution | 0.162 |
| Gamma distribution | 0.173 |
| Logarithm normal distribution | 0.217 |
As shown above, the standard deviation of Vessels arrival rule matching normal distribution is minimum, therefore boats and ships generation module is according to normal distribution next life
Become boats and ships.
Lockage rule according to boats and ships, Three Gorges lockage boats and ships are simplified as six classes, are passenger boat, Commercial Vehicle roll-on-roll-off ship, packaging respectively
Case ship, dangerous materials ship, Bulk Cargo Ship and other boats and ships.
Table 3 boats and ships generate submodel boats and ships arrival interval parameter list
Parameters in Ship ' generation module.
(1) average: the meansigma methods of the natural law of various ships arrival interval.
(2) variance: the variance of the natural law of various ships arrival interval.Calculate average and the variance of uplink and downlink respectively, and select
Select normal distyribution function to be fitted.
4.2, boats and ships organizational scheduling module:
Various ships needs to follow universal law when by Three Gorges Ship Lock and Gezhouba Shiplock:
(1) Gezhouba Shiplock list ship list mistake, Three Gorges ship lockage rule is more complicated, and principle is to arrive first first mistake, and part is preferential,
Combination lockage.
(2) priority level of various ships is the most different, and according to the principle that people-oriented, it is the highest that passenger boat belongs to priority；Business
Product car roll-on-roll-off ship takes second place, and third, reason is all that the surcharge of boat-carrying commodity is higher to container ship, lockage waiting time mistake
Length can cause the loss that shipowner is bigger；Then it is exactly Bulk Cargo Ship and other boats and ships；Dangerous goods shipping is more special, it is impossible to
Other any boats and ships mixing lockages, so dangerous goods shipping can only wait that the full lock time of collection could lockage.
Ship combination rule submodel Main Function is the order of classes or grades at school arranging ship lockage and rule, in the feelings in accordance with actual rule of arranging an order according to class and grade
Ship lockage scene is reduced to greatest extent under condition.Module designs as shown in Figure 3.
4.3, ship lockage submodel:
Ship lockage submodel is divided into Three Gorges Ship Lock module and Gezhouba Shiplock module, is used for simulating boats and ships by Three Gorges Ship Lock and Pueraria lobota
The process of dam, continent ship lock.
As a example by down bound vessel oceangoing ship, after arranging an order according to class and grade through dispatcher, first boats and ships sail Three Gorges Ship Lock approach channel into, and then boats and ships enter
Enter a lock chamber closed shutter, the water in a lock chamber is discharged and makes the water level of one No. two lock chambers maintain an equal level, then open gate and make
Ship drives towards No. two lock chambers, the like, until sailing downstream into.According to the real process of ship lockage, this model is by Three Gorges five
Level ship lock is simplified to third-order sequence.Then boats and ships enter Gezhouba Reservoir Region, pass through Gezhouba Shiplock subsequently and sail out of Three Gorges Pivot Project.
Its process simulation is as shown in Figure 4.
4.4, the inspection of phantom:
This phantom is divided into two subsystems of uplink and downlink, and each subsystem includes boats and ships generator, ship combination rule
Module, ship lockage module and ship lift module.This research is by one week (7 days), one month (30 days), 1 year (365 days)
The boats and ships of 3 durations are analyzed by value with reality by the emulation quantity of Three Gorges Ship Lock.(phantom data and
Within 2013, truthful data is more as shown in table 4)
The error analysis of table 4 system emulation
As shown in Table 4, the error of Computer Simulation is all not above 10%, and along with the increase of emulation duration, simulation result with
The relative error of practical situation is gradually reduced, and embodies this model and has certain reasonability, may be used for further emulating grinding
Study carefully.
Step 5, Three Gorges Pivot Project ship lift emulate
According to above-mentioned analysis, the analysis result of this model and Three Gorges navigation actual quantity error within 10%, then can utilize this
Model is studied further.
5.1, ship lift module design: according to design, Three-Gorges Ship-lift will come into operation in 2015, and the design of ship lift is
Overstock to alleviate boats and ships, increase the facility of Three Gorges handling capacity.It is up and descending that ship lift taken by boats and ships, it is allowed to enters and rises
The boats and ships of ship machine are necessarily less than 3000 tonnes；And the capacity of ship lift every day is limited, and single line time is spaced apart 40 minutes, because of
This, one direction can be by the boats and ships of 16 less than 3000 tonnes every day.Wherein, dangerous goods shipping can not take advantage of ship lift lockage,
Therefore have other five classes spitkits and can cross ship lift.Ship lift module is as shown in Figure 5.
5.2, ship rule EVOLUTION ANALYSIS is carried out: along with the improvement of shipping condition after Three Gorges Projects water-retention, it is fast that Three Gorges Ship Lock crosses the dam volume of goods transported
Speed increases, and larger-sized vessel, standardization trend are day by day obvious, have just reached 1.003 by the volume of goods transported of Three Gorges Ship Lock in 2011
Hundred million tons, within 19 years the most in advance, reaching to design handling capacity, the lockage volume of goods transported of 2014 is 1.15 hundred million tons, has scholarly forecast 2020
Year, the Three Gorges volume of goods transported was by breakthrough 200,000,000 tons.The tonnage of lockage boats and ships increases also with the trend of larger-sized vessel, wherein, and 2014
Year Three Gorges lockage tonnage of ship is 3784 tons.The boats and ships of less than 3000 tonnes, and dangerous materials ship can only be transported in view of ship lift
Oceangoing ship can not cross ship lift, and this section considers the lockage total volume of freight by ships and the lockage tonnage of ship predicts the following ship lockage volume of goods transported
It is respectively 1.5 hundred million tons and the year lockage boats and ships flow of 200,000,000 ton hours, and according to available data to shared by about 3000 tonnes boats and ships
Ratio is analyzed and predicts.Following table illustrates Three Gorges lockage boats and ships flow and type distribution.
Boats and ships flow that the table 5 Three Gorges difference lockage volume of goods transported is corresponding and tonnage of ship table
Boats and ships flow increases along with the increase of the lockage volume of goods transported, it is contemplated that the lockage tonnage of ship is also being continuously increased, therefore, and ship
The increase of oceangoing ship flow not increase to the lockage volume of goods transported is directly proportional；The trend of larger-sized vessel is more and more obvious, annual 3000 tons
Above boats and ships proportion rises steadily, year the lockage volume of goods transported reach 100,000,000 ton hour ratios and reach 52.54%, but over time
Passage, amount of increase will slowly reduce, year the lockage volume of goods transported reach more than 3000 tonnes boats and ships of 200,000,000 ton hour and reach 69.56%.
Ship lift emulates: being 1.5 hundred million tons by following for the simulation lockage volume of goods transported is 200,000,000 tons of two kinds of sights with the lockage volume of goods transported, by upper
Joint carrys out the data that obtain of ship rule EVOLUTION ANALYSIS and inputs as parameter, research ship lift come into operation after the overstocked situation of boats and ships.?
10 days, 20 days, 30 days are emulated respectively under both of these case.Running the time due to ship lift one way is 40min, also boats and ships
The time of turnover ship lift, it is assumed that ship lift single line every day can cross the ship of below 12 3000t levels, following behavior example, respectively mould
Intending the lockage volume of goods transported is 1 hundred million to 2 hundred million ton hour, compares the boats and ships before and after ship lift uses and overstocks quantity.
The behaviour in service list position of ship lift during the table 6 different lockage volume of goods transported: ship/time
As listed by table 6, in the case of the lockage volume of goods transported is 100,000,000 tons, by the data without overstocking in the case of ship lift and actual number
According to contrasting, both are the most identical, it was demonstrated that the reasonability of this model in the case.
Step 6, ship lift analysis of simulation result
(1) it is 100,000,000 ton hours when the lockage volume of goods transported, uses ship lift than not using the boats and ships of ship lift to overstock quantity and decrease 80%
Left and right, and basicly stable, now ship lift utilization rate is less than 30%, ability to work unsaturation, can effectively alleviate overstocked situation.
(2) reaching 1.5 hundred million ton hours when the lockage volume of goods transported, boats and ships flow amplification is little, ship lift utilization rate between 40%-60%,
Its ability to work can also effectively alleviate overstocking of less than 3000 tons boats and ships, and therefore boats and ships overstock quantity and also control in less scope
In, amount of decrease is also basically stable at about 60%.
(3) rise to 200,000,000 ton hours when the lockage volume of goods transported, affected by growth and the larger-sized vessel of boats and ships flow, 3000 tonnes
Above ships quantity is significantly increased, and lock throughput capacity is extremely limited, and large ship overstocks quantity and substantially rises.On the other hand,
Less than 3000 tonnes ships quantities are also continuously increased, and ship type becomes increasingly complex, and boats and ships overstock more and more obvious.Now, rise
Ship machine utilization rate basically reaches 100%, and its ability to work is the most saturated.
Step 7, analysis result
All in all, ship elevator all right, it alleviates and overstocks effect and taper off trend along with the increase of the lockage volume of goods transported,
Its utilization rate then increases in increasing trend with the volume of goods transported, when the volume of goods transported approaches 100% close to 200,000,000 ton hours, the utilization rate of ship lift,
The operation of long-time high load capacity can cause ship lift Frequent Troubles.Ship lift is as alleviating the overstocked scheme of boats and ships to a certain extent
There is positive effect, if but following large ship is more and more and boats and ships flow increases too fast, and the effect of ship lift just ratio is relatively limited,
Root problem cannot be solved, need new scheme badly.
Above example is merely to illustrate design philosophy and the feature of the present invention, its object is to make those skilled in the art's energy
Solution present disclosure much of that is also implemented according to this, and protection scope of the present invention is not limited to above-described embodiment.So, all according to this
Equivalent variations that bright disclosed principle, mentality of designing are made or modification, all within protection scope of the present invention.
