Solving the time capacitated arc routing problem under fuzzy and stochastic travel and service times
Networks, Volume 82, Issue 4, Page 318-335, December 2023., 2023 Abstract Stochastic, as well as fuzzy uncertainty, can be found in most real‐world systems. Considering both types of uncertainties simultaneously makes optimization problems incredibly challenging. In this paper we propose a fuzzy simheuristic to solve the Time Capacitated Arc Routing Problem (TCARP) when the nature of the travel time can either be ...

The location routing problem with facility sizing decisions
International Transactions in Operational Research, Volume 30, Issue 2, Page 915-945, March 2023., 2023 Abstract The location routing problem (LRP) integrates operational decisions on vehicle routing operations with strategic decisions on the location of the facilities or depots from which the distribution will take place. In other words, it combines the well‐known vehicle routing problem (VRP) with the facility location problem (FLP).

Disruption Management Approaches for Berth Scheduling in Bulk Terminals
Journal of Advanced Transportation, Volume 2022, Issue 1, 2022., 2022 Maritime terminals are complex transportation systems sensitive to several sources of uncertainty. An alteration in the baseline planning, as a consequence of one or more disruptive events, can lead terminals to a lower quality of the service provided.

A SIMHEURISTIC ALGORITHM FOR SOLVING AN INTEGRATED RESOURCE ALLOCATION AND SCHEDULING PROBLEM [PDF]
2018 Winter Simulation Conference (WSC), 2018 Modern companies have to face challenging configuration issues in their manufacturing chains. One of these challenges is related to the integrated allocation and scheduling of resources such as machines, workers, energy, etc. These integrated optimization problems are difficult to solve, but they can be even more challenging when real-life uncertainty ...
