in integer programming. The candidate will join the research team AOC of
LIPN for working on exacts and heuristics methods for the Inventory
Routing Problem.
The position is open to international candidates. Further information
and application details can be found here:

CONTEXT
========
Air Liquide has developed an optimization tool to optimize daily bulk
deliveries around the world. The tool is based on a subsequent model
that solves an Inventory Routing Problem (IRP). The algorithm decides
when and how much product to deliver to each customer in a dispatch zone
and builds routes for the necessary deliveries. This tool allows
Operations teams to optimize the liquid distribution by minimizing
different costs and taking into account several specific constraints
related to Air Liquide business while ensuring a good customer service
level.
OBJECTIVES AND ORGANIZATION
=============================
The objective of the postdoctoral mission is to challenge the current
algorithm. In fact, it's based on a heuristic approach that runs within
a limited computational time in order to find a feasible solution of
good quality. Air Liquide wants to develop an exact (or pseudo-exact)
method and lower bounds to qualify the convergence and the optimality of
the current heuristic.
The postdoctoral mission will be jointly managed by Air Liquide R&D team
and by AOC team (Algorithms and Combinatorial Optimization) of Computer
Science Lab (LIPN) of Paris Nord University represented by Pr. Roberto
Wolfler Calvo.
The mission will last one year, preferably to be started as soon as possible
The post will be open until the position is filled
REQUIRED PROFILE
=================
- PhD scientist / researcher specialized in Vehicle Routing Problem and
Recognized competency in Operations Research and Computer science
- Proficiency of English – all documentation will be in English.
