PortML.Documents 1.1.47

1. About

PortML stands for Port Markup Language. It is a descriptive language or document which describes container port assets, such as yard blocks, quay cranes, wharves, and AGVs, as a markup code for modelling and simulation.

PortML document follows the PortML specification which is defined in the schema file PortML.xsd. The schema defines all of the datatypes and base infrastructure types.

2. How to Use

using (StreamReader file = new StreamReader("<path to PortML document>"))
{
    try
    {
        string portMLDocument = file.ReadToEnd();

        var parser = new PortML.Documents.PortMLParser();
        var portML = parser.Parse(portMLDocument);
        ...
    }
    catch (Exception ex)
    {
        ...
    }
}

3. Terminal

There will be one and only one Terminal module in the same PortML document. It is to specify the boundary of the terminal and to provide static properties which are general to the entire port system.

To retrieve the terminal information from the PortML object, use the following code.

var terminal = portML.GetTerminal();

The code above will return a list of TerminalInfo object which contains the following information.

4. Wharf

Wharf is the side of the port terminal where vessels will be parked at.

Quay cranes will be located at the land side of the wharf while vessels will be parked at the sea side. As shown in the following diagram, the direction of the wharf, defined by StartingAt and EndingAt, is important. The wharf direction will decide which side of it is land side and which side of it is sea side.

To retrieve the wharf information from the PortML object, use the following code.

var wharfs = portML.GetAllWharfs();

The code above will return a list of WharfInfo object which contains the following information.

5. Yard Block

Yard block module is corresponding to the container yard in the sea port terminal.

The starting point and facing direction of a yard block is defined in the way shown in the following diagram. The Facing property defines the direction of the yard block in radian rotating around the StartingAt point.

To retrieve the yard block information from the PortML object, use the following code.

var yardBlocks = portML.GetAllYardBlocks();

The code above will return a list of YardBlockInfo object which contains the following information.

6. Traffic Network

To retrieve the traffic network from the PortML object, use the following code.

var trafficNetwork = portML.GetTrafficNetwork();

6.1 Quay Points

To retrieve the quay point information from the trafficNetwork object, use the following code.

var quayPoints = trafficNetwork.QuayPoints;

The code above will return a list of ControlPointInfo object which contains the following information.

6.2 Yard Points

To retrieve the yard point information from the trafficNetwork object, use the following code.

var yardPoints = trafficNetwork.YardPoints;

The code above will return a list of ControlPointInfo object which contains the following information.

6.3 Quay-Point-to-Yard-Point Distance

To retrieve the distance from each quay point in the traffic network to another yard point, use the following code.

var distanceMatrix = trafficNetwork.PointDistancesFromQuayPointToYardPoint;

The code above will return a list of PointToPointDistanceInfo object which contains the following information.

This distance is calculated using Dijkstra's algorithm in the graph of the traffic network.

6.4 Yard-Point-to-Quay-Point Distance

To retrieve the distance from each yard point in the traffic network to another quay point, use the following code.

var distanceMatrix = trafficNetwork.PointDistancesFromYardPointToQuayPoint;

The code above will return a list of PointToPointDistanceInfo object which contains the following information.

This distance is calculated using Dijkstra's algorithm in the graph of the traffic network.

6.5 Yard-Point-to-Yard-Point Distance

To retrieve the distance from each yard point in the traffic network to another yard point, use the following code.

var distanceMatrix = trafficNetwork.PointDistancesFromYardPointToYardPoint;

The code above will return a list of PointToPointDistanceInfo object which contains the following information.

This distance is calculated using Dijkstra's algorithm in the graph of the traffic network.

7. Quay Crane Statistics

To retrieve the operating time statistics of a quay crane, use the following code.

var quayCraneStatistic = portML.GetQuayCraneStatistic();

The code above will return a list of QuayCraneInfo object which contains the following information.

8. Yard Crane Statistics

To retrieve the operating time statistics of a yard crane, use the following code.

var yardCraneStatistic = portML.GetYardCraneStatistic();

The code above will return a list of YardCraneInfo object which contains the following information.
