Solver for the Multi Depot Cumulative Capacitated Vehicle Routing Problem

Introduction

The Multi Depot cumulative Capacitated Vehicle routing Problem is an optimizationproblem for vehicle routes which was recently formulated. Its objective is to minimize the arrival time of a fleet of vehicles to a group of clients, taking into account the capacity ofthe vehicles. This problem can be very useful when applied to natural disaster situations, where the arrival time to the possible victims is crucial.

Installation

The package can be installed through npm:

npm install genetics-js-mdccvrp

Usage

There are two ways to use the package, you can either execute the script solve with the CLI or you can integrate the solver in your web application.

CLI

To execute the solver, run the script solve specifying if the algorithm to execute is the memetic or the random algorithm using the commands of the same name with the arguments below.

Solver integration

In order to integrate the solver, the algorithm parameters with the type:

SimpleMemeticParams<
 FitnessProportionalSelectionParams<
   RouteIndividual, List<BaseNode>>, BaseRouteCrossoverParams
 >

Then pass them to the algorithm and it can be executed when passed an instance and a fleet size.

import { SimpleMemetic } from 'genetics-js-mdccvrp';

const algorithm = new SimpleMemetic(algorithmParams);

alogorithm.solve(instance, fleetSize);
