[DMANET] A PostDoc Position at AOC team - LIPN and AirLiquide

University Paris 13 and AirLiquide are offering a postdoctoral position
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:

July 13th.pdf

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 in September
2012.

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.
