A comparative analysis of MIP formulations for the multi-mode resource-constrained independent task scheduling problem
( Springer , 2025 , Article)We consider the problem of scheduling independent multi-mode tasks with multiple renewable resource constraints, aiming to minimize the weighted sum of tardinesses. This problem commonly arises in the context of multiproject ... -
A General Framework for Building Resilient Global Supply Chains
( IEEE , 2023 , Conference)With the rapid globalization and expansion of supply chains, the risk of disruptions has increased, leading to severe financial losses and operational shutdowns. The pursuit of global integration and efficiency has further ... -
A hybrid simulation-optimization approach for the robust Discrete Time/Cost Trade-off Problem
( Elsevier , 2015 , Article)We investigate a stochastic Discrete Time/Cost Trade-off Problem. This multimode project scheduling problem, requires assigning modes to activities, and scheduling the activities so that the sum of the activities cost and ... -
A lifted compact formulation for the daily aircraft maintenance routing problem
( INFORMS Inst.for Operations Res.and the Management Sciences , 2013 , Article)Given a set of flights for a specific fleet type the aircraft routing problem (ARP) determines the flying sequence for each individual aircraft while incorporating specific considerations of minimum turn time maintenance ... -
A matheuristic for the robust integrated airline fleet assignment, aircraft routing, and crew pairing problem
( Elsevier , 2022 , Article)We address an integrated airline scheduling problem that combines three airline planning processes: fleet assignment, aircraft routing, and crew pairing. For a given daily flight schedule, the problem requires simultaneously ... -
A model for enhancing robustness of aircraft and passenger connections
( Elsevier , 2013 , Article)Airlines schedules are often subject to various uncontrollable factors that cause disruptions and delays. These delays not only constitute, for many passengers, the painful part of air travel, but also represent for airlines ... -
A novel model and decomposition approach for the integrated airline fleet assignment, aircraft routing, and crew pairing problem
( INFORMS Inst.for Operations Res.and the Management Sciences , 2017 , Article)Given a daily flight schedule and a set of aircraft fleets, the airline scheduling problem assigns individual aircraft and groups of crew to each flight based on specific considerations of aircraft maintenance requirements ... -
A particle swarm optimization approach for predicting the number of COVID-19 deaths
( Nature Research , 2021 , Article)The rapid spread of the COVID-19 pandemic has raised huge concerns about the prospect of a major health disaster that would result in a huge number of deaths. This anxiety was largely fueled by the fact that the severe ... -
A simulation-optimization approach for robust aircraft routing
( Universite de Lorraine , 2015 , Conference)To mitigate the impact of unpredictable disruptions, airlines are seeking to pro-actively design schedules that incorporate some robustness features. In this paper, we propose a novel simulation-optimization approach using ... -
A simulation-optimization approach for the stochastic discrete cost multicommodity flow problem
( Taylor and Francis Ltd. , 2020 , Article)This article addresses a variant of the Discrete Cost Multicommodity Flow (DCMF) problem with random demands, where a penalty is incurred for each unrouted demand. The problem requires finding a network topology that ... -
An assignment-based lower bound for a class of two-machine flow shop problems
(2013 , Article)We present an assignment-based lower bound that is valid for a wide class of two-machine flow shop problems with a regular additive performance criterion. We provide empirical evidence that this new bound consistently ... -
An exact algorithm for the single machine problem with unavailability periods
( Inderscience Publishers , 2015 , Article)We investigate the single machine scheduling problem with job release dates and due dates, and multiple planned unavailability time periods. This problem arises in the context of machine scheduling with planned preventive ... -
An integrated approach for airline flight selection and timing, fleet assignment, and aircraft routing
( INFORMS Inst.for Operations Res.and the Management Sciences , 2013 , Article)Airline profits critically depend on the nature and efficiency of service they provide and accrue from a complex planning process involving schedule design fleet assignment aircraft routing and crew scheduling which are ... -
Anticipating the impacts of mega events on host-country agri-food supply chains: a synthesis based on a simulation of the World Cup 2022 in Qatar
( Elsevier , 2025 , Conference)Agri-food supply chains are likely to be disrupted during mega events. In order to prevent food waste and financial losses, it is crucial to respond and recover quickly from these disruptions. In fact, hosting such events ... -
A blockchain-based framework to optimize shipping container flows in the hinterland
(2023 , Article)We address two interrelated issues affecting the hinterland portion of the maritime container supply chain: reducing the movement of empty containers and reducing empty trips by trucks carrying these containers. In this ... -
Building resilience in the infant formula milk supply chain
( Elsevier , 2024 , Article)In recent years, Infant Formula Milk (IFM), a vital source of nutrition for infants lacking breast milk in their first two years, has been plagued by diverse and severe global supply chain disruptions. These challenges ... -
Combinatorial benders decomposition for the two-dimensional bin packing problem
( INFORMS Inst.for Operations Res.and the Management Sciences , 2021 , Article)The two-dimensional bin packing problem calls for packing a set of rectangular items into a minimal set of larger rectangular bins. Items must be packed with their edges parallel to the borders of the bins, cannot be ... -
The cost of carrier consistency: Last-mile delivery by vehicle and drone for subscription-based orders
( Taylor and Francis Ltd. , 2024 , Article)We investigate a deterministic last-mile delivery problem in which a firm delivering scheduled orders determines a subset of customers to be prioritized for drone delivery, relegating the rest to vehicle delivery. The ... -
Data of the design of solar assisted district cooling systems
( Elsevier , 2020 , Dataset)The collected datasets are relevant and related to Optimization of Design and Operation of Solar Assisted District Cooling Systems [1] paper. Part of the data is collected on the main and common components of the system. ... -
Enhanced compact models for the connected subgraph problem and for the shortest path problem in digraphs with negative cycles
(2013 , Article)We investigate the minimum-weight connected subgraph problem. The importance of this problem stems from the fact that it constitutes the backbone of many network design problems having applications in several areas including ...
