Internship - Integrated Transit System with Electric Ride-sharing and Mobility Pickup Stations in Smart Grid (H/F)

Le descriptif de l’offre ci-dessous est en Anglais_
**Niveau de diplôme exigé**: Bac + 3 ou équivalent
**Fonction**: Stagiaire de l'ingénierie
**Mission confiée**:
Recently, the integration between machine learning and operations research has been a novel trend to tackle
problems with stochasticity. For example, Baty et al. [2024] tackle the dynamic vehicle routing problem
(VRP) with real-time customer requests. The task involved a rapid delivery service using capacitated vehicles
to serve customer requests originating from a depot. Each request had to be served within a specified time
window. Requests arrived dynamically, and vehicles were dispatched in waves to serve them. At each wave’s
decision time t, the system state Xt consists of the set of requests that have not yet been served. The
decision Yt involves selecting the subset of requests to be served by the vehicles dispatched at time t, as well
as the corresponding routing plan. The objective is to find a policy h that minimizes the expected total
routing cost. The authors proposed hybrid machine learning pipelines to tackle the problem, which includes
two layers: a graph neuro network (GNN) to predict the “prize” of serving each request in the graph and
a combinatorial optimization layer to solve a price-collection capacitated vehicle routing problem at each
decision epoch t to produce the routing solution with the predicted prizes. Another important stream is
to integrate Large Language models (LLMs) into optimization, where the optimization task is described
in natural language. In each optimization step, the LLM generates new solutions from the prompt that
contains previously generated solutions with their values, then the new solutions are evaluated and added
to the prompt for the next optimization step. This idea has been demonstrated efficient in solving traveling
salesman problems (TSP) (Yang et al. [2023]).
**Principales activités**:
The objective of the internship is to implement combinatorial optimization augmented machine learning
(COAML) method and LLM to solve dynamic electric autonomous dial-a-ride problem (E-ADARP). The
static version of the E-ADARP with determined requests has been fully analyzed in Bongiovanni et al. [2019],
Su et al. [2023, 2024]. The first step is to leverage the existing resource of Baty et al. [2024], Yang et al.
[2023] to solve the dynamic DARP - a simplified version of dynamic E-ADARP by deactivating charging
options. It would be a good example to start, as the dynamic DARP is extended from VRP and TSP. The
obtained results will be benchmarked with literature.
