  PAPmap: Partitioning-Assignment problem for distributed 3D mapping by UAV swarming

  • Leandro R. Costa, presenter, Polytechnique Montréal - GERAD

  The unmanned aerial vehicle (UAV) swarming will shortly play an essential part in plenty of real-life applications. We propose the NP-hard problem: Partitioning-Assignment Problem for distributed 3D mapping by UAV swarming. The goal is to minimize the makespan of a 3D reconstruction procedure while respecting spatial, communication, and reliability constraints./Branch-and-cut; 3D reconstruction; UAV swarming;

  Paint-waste management problem

  • Mucahit Cevik, Ryerson University
  • Juyoung Wang, presenter, University of Toronto
  • Amir Ali Parsaee, Ryerson University
  • Saman Hassanzadeh Amin, Ryerson University

  We study paint-waste network-flow multi-objective optimization problem with three objective functions:
  cost, transportation risk and inconvenience. The problem will be decomposed into four logistic steps:
  waste generation nodes, collection centers, treatment centers and disposal sites. We present our
  experimental results and analysis on an Ontario-based case study.

  Keywords: Household hazardous waste (HHW), Network flow, Integer programming

  Modeling employees' psychological well-being at work with artificial neural networks

  • Mark Somers, New Jersey Institute of Technology
  • Jose Casal, presenter, New Jersey Institute of Technology

  Predictive models of well-being have yielded weak results leading to calls for new methods and new approaches. With a national probability sample of working adults in the United States, ANN's yielded significantly greater predictive accuracy than did multiple linear regression for two indices of well-being, work stress and life satisfaction.

  Keywords; artificial neural networks; work stress; life satisfaction

  New models and preprocessing techniques for segment routing optimization

  • Bernard Fortz, presenter, Université Libre de Bruxelles

  Segment routing is a modern variant of source routing in computer networks, which is being developed within the SPRING and IPv6 working groups of the IETF. In a segment routed network, an ingress node may prepend a header to packets that contain a list of segments, which are instructions that are executed on subsequent nodes in the network. These instructions may be forwarding instructions, such as an instruction to forward a packet to a specific destination or interface. In this talk, we present models for traffic engineering in a network implementing segment routing on top of shortest paths routing protocols. We also present some pre-processing techniques that allow to decrease significantly the size of the resulting models, and present numerical experiments validating the approach on a large set of test instances.
