NaturalShift is a .NET library useful to compute workshifts. Computation is based on a genetic algoritm. Number of days, shifts and shifters can be configured, together with many other constraints and directives. See the wiki for a complete explaination.
NuGet compiled package is available at https://www.nuget.org/packages/NaturalShift
To install NaturalShift, run the following command in the Package Manager Console
Install-Package NaturalShift
The following code starts computation of a workshift scheme 30 days long, with 14 shifts and 18 employees. The computation lasts 30 seconds.
var problem = ProblemBuilder.Configure()
.WithDays(30)
.WithSlots(14)
.WithItems(18)
.WithMaxConsecutiveWorkingDaysEqualTo(5)
.RestAfterMaxWorkingDaysReached(2)
.Build();
var solvingEnvironment = SolvingEnvironmentBuilder.Configure()
.ForProblem(problem)
.WithPopulationSize(100)
.RenewingPopulationAfterSameFitnessEpochs(10)
.StoppingComputationAfter(30).Seconds
.Build();
var solution = solvingEnvironment.Solve(); //takes about 30 seconds
Console.WriteLine(solution);
Console.WriteLine("Press a key...");
Console.ReadLine();The best solution found during computation is printed to the console.
Too tricky? Read the wiki! :-)
In the wiki you can find a lot of useful information about how to use and configure this library. Wiki clearly explains the concepts behind NaturalShift and all of its features.
NaturalShift is released under the terms of AGPL-3.0 license. This library is Free Software because of this.
