Electric Vehicle Route Optimization: Plan Delivery with Simulation Software

Electric Vehicle Route Optimization: Plan Delivery with Simulation Software

Problem

Electricite de France (EDF) is the largest public electricity company in France. One of its activities is electric charging infrastructure development and energy-efficient vehicle popularization. Within this area, the company launched a project to create a tool for the operative management of delivery by electric trucks in Paris and its suburbs.

The company needed to optimize routes to ensure that all orders were delivered on time. To this end, EDF opted for simulation modeling software and decided to integrate a separate electric battery charging optimization algorithm into the developed model.

Delivery route optimization model — depot

Solution

The EDF specialists built a delivery model in AnyLogic simulation software. To reflect the real system more precisely, they considered several constraints:

For the delivery route optimization model, the development team used the agent-based simulation method to describe the electric trucks’ operation. For each truck, they defined characteristics (vehicle dimensions, speed, load weight, etc.) and states (waiting, loading, unloading, on route, etc.) that changed over time when the model was run.

Delivery route optimization model — map view

Furthermore, in the simulation there were two types of electric trucks with differed battery capacity. The team also set charging station parameters such as GPS position and individual chargers’ power.

After that, with AnyLogic software capabilities, the developers located the remaining logistics network facilities on a GIS map. They also set up 2D and 3D visualization of the charging station and electric trucks. With this, the user could easily switch from the map view of Paris and the suburbs, which enabled observing the whole system work, to a more detailed object operation view.

The outputs of the delivery route optimization model were routes displayed on a GIS map with statistics on the charging station, on each charger, on the trucks’ states, and on the order state.

In the simulation, the EDF team could vary traffic density, change some of the preset parameter values, turn chargers on and off, and observe how these changes affected the operation of the entire logistics network.

Delivery route optimization model — depot statistics

Results

While working on the project, the EDF team had a delivery route optimization simulation model developed, visualized the logistics network, and collected statistics using AnyLogic software.

The model helped them calculate the optimal number and ratio of electric trucks with different types of batteries in the fleet. They also identified the number of chargers and the amount of power they should have to support uninterrupted and timely delivery of goods by electric vehicles.

When the model was finished, the EDF team integrated a separate battery charging optimization algorithm in it. As soon as the algorithm was calibrated, the company was going to develop a tool for real-time operational management of delivery by electric trucks.
