    Exploiting landmark constraints for mobile robot localization and mapping

    • Duowen Qian, presenter,

    This work considers exploiting a priori landmark information within the nonlinear least-squares algorithm to estimate the location of a mobile robot in a planar environment. Additionally, newly observed landmarks are augmented to the a priori landmarks, realizing mapping as well as localization.

  • 03:55 PM - 04:20 PM

    A Two-Echelon Location-Routing Problem in the Dutch inland waterway network

    • Rogier Deluster, presenter, CIRRELT
    • Leandro C. Coelho, Université Laval

    Refueling of liquefied natural gas (LNG) ships is called “bunkering” and can be done from a bunker terminal, from a LNG tanker truck or from a LNG bunker ship. This project determines the most cost effective fleet and facility composition for a cost effective transition to a LNG powered waterway network in The Netherlands.

  • 04:20 PM - 04:45 PM

    Hub location under the risk of interdiction

    • Prasanna Ramamoorthy, Indian Institute of Management Ahmedabad
    • Sachin Jayaswal, presenter, Indian Institute of Management Ahmedabad
    • Ankur Sinha, Indian Institute of Management Ahmedabad
    • Navneet Vidyarthi, Concordia University

    We study the hub-and-spoke network design problem under the risk of interdiction. The problem is modeled as a 3-stage sequential game, resulting in a tri-level mixed integer program. We present different approaches to reduce the model to 2 levels, followed by an efficient exact method to solve the problem to optimality.

  • 04:45 PM - 05:10 PM

    Where to locate the new depot of a food company: a case study in Montreal

    • Narges Sereshti, HEC Montréal
    • Matthieu Gruson, presenter, HEC Montreal
    • Gilbert Laporte, HEC Montréal

    In this project, we dealt with the problem of locating new depot in the Montreal area to better satisfy the clients of a food delivery company. We used the facility location model and the CVRPTW to solve this problem and define the location and the number of vehicles of the new depot.
