Job description

Within Wayfair, the EU Supply Chain Analytics team focuses on improving Wayfair’s supply chain with mathematical modelling and optimization, for example by designing and implementing models for network planning or routing.

A challenging task for you

Your task will be the design and implementation of an algorithm to solve a rich vehicle routing problem (VRP) from Wayfair’s supply chain. The problem at hand combines traits of a travelling salesman problem (TSP), a periodic VRP, a VRP with time windows, a stochastic VRP, an open VRP and an ambulance location problem. 

Introductory literature: 

  • Brotcorne, Luce, Gilbert Laporte, and Frederic Semet. "Ambulance location and relocation models." European journal of operational research 147.3 (2003): 451-463. PDF
  • Francis, Peter, and Karen Smilowitz. "Modeling techniques for periodic vehicle routing problems." Transportation Research Part B: Methodological 40.10 (2006): 872-884. PDF
  • Gendreau, Michel, Gilbert Laporte, and René Séguin. "Stochastic vehicle routing." European Journal of Operational Research 88.1 (1996): 3-12. PDF

A structured approach to your master thesis:

Your internship with Wayfair will have a total duration of six paid months. During five months, you will work full time at Wayfair mainly on this project. In the final month, you are released from work to focus exclusively on writing your master thesis. In the course of your first five months, you will be guided by experienced colleagues through the following steps:

  • Literature research
  • Problem formulation as mixed integer problem (MIP)
  • Implementation of the MIP and solution with a state-of-the-art solver on several instances 
  • Design and implementation of a problem-specific heuristic
  • Numerical tests for feasibility, solution speed and quality

What You'll Need

  • Initial exposure to quantitative modelling and mathematical optimization, e.g. within university course or bachelor thesis
  • Experience with programming in Python
  • Desire to always be learning, and a collaborative team-player attitude!
