Create Starting Point

Click a location on the map, then click the Create Starting Point button on the upper right of the map, the following Starting Point Template dialog will be presented. Follow the three steps in the figure below to add land vehicles and aircrafts which will be starting from this starting point. Click the OK button to create the starting point or Cancel button to cancel the action. Note that for each of the fleet, it must be assigned to one of the ending point.

Create Control/Rest/Ending Point

The steps for creating control/rest/ending points are similar, user can refer to the creation of control point as an example for other two points.

Click a location on the map, then click the Create Control Point button on the upper right of the map, Control Point Template dialog will be presented. Follow the steps in the Figure below to add the fleets to the control point to be created. Lastly, click OK to create the point.

Create Supply/Demand Point

The steps for creating supply and demand points are similar, user can refer to the creation of demand point as an example to create supply point as well.

Click a location on the map, then click on the Create Demand Point button on the upper right of the map, Demand Point Template dialog will be presented. After changing the parameter values, click OK button to create the demand point.

Update User-Defined Point

After user has created a user-defined point such as supply point, user can go back and update/delete the point by selecting it on the map.

Routing

After user defines all the points, user can click on the Route button to generate the routes for the supply chain routing, as shown in Figure below. Note that clicking once on the Route button may not be sufficient, user may need to press the button several times until the status bar at the lower right of the map change from NotStarted to Routed.

Simulation

Click the Start Simulation button to start the simulation after routing, as shown in Figure below. User can then stop/continue the simulation or increase/decrease the simulation speed by clicking the buttons next to the Start Simulation button.

Reset

Click the Reset button at the lower right of the map to clear all the user-defined points and routes on the map to restart. User can go to any location in the world to setup the supply chain simulation, by entering the name of the location in the text box at the lower left of the map and click on the Goto button.

2.Scheduler Library

Vehicle Routing Scheduler Library is a library built as a framework to solve various vehicle routing problem variants. Its primary objective is to provide a platform for researchers and developers to design, experiment and use vehicle routing solvers for existing and new vehicle routing challenges.

Therefore, it is designed to be modular and domain-driven. It provides users with variety of tools and interfaces such as algorithm analysis, performance analysis, problem analysis, geo-distance calculation, map-based routing, route sheet, and so on, which target for real-world vehicle routing problem implementation. The library is built from scratch and based on several research works undertaken by the developers of this library.
