Anylogic: How to add costs (per route) per time of day? - database

Question

I have data on different costs per route per time of day for container transport (e.g., from zone A to zone B in the morning; the total costs of transport are 100 euros), for almost 200 zones with 4 times of day. How can I assign these costs in my Anylogic model per route per time of day?
(after this I would like agents (trucks) to decide (based on the costs) which route and time of day to travel)

Answer 1

Given no example data I am using some made-up data to give you an example of how to do this.
Suppose I have the following route and cost data
You can import this into the AnyLogic DB and then use them to populate a custom class with your data.
For example here is a custom Java class for your routes
public class MyRoute {
String id;
String from;
String to;
LinkedHashMap<String, Double> routeCosts = new LinkedHashMap<String, Double>();
/**
* Default constructor
*/
public MyRoute(String id, String from, String to) {
this.id = id;
this.from = from;
this.to = to;
}
public void addCost(String timeOfDay, double cost) {
routeCosts.put(timeOfDay, cost);
}
}
And then I have a little function to populate them from the DB
List<Tuple> rows = selectFrom(routes).list();
for (Tuple row : rows) {
MyRoute route = new MyRoute(
row.get( routes.route ),
row.get( routes.from_db ),
row.get( routes.to_db )
);
// Add costs
List<Tuple> costRows = selectFrom(costs)
.where(costs.route.eq(route.id))
.list();
for (Tuple costRow : costRows) {
route.addCost(
row.get( costs.time_of_day ),
row.get( costs.cost )
);
}
}
Now you can sort the routes based on the costs or time of day and use this to make your decisions
