Robust optimization for the discrete time-cost tradeoff problem with cost uncertainty
( Springer International Publishing , 2015 , Book chapter)Projects are subject to various sources of uncertainty that hamper reaching project targets; hence, it is crucial importance to use effective approaches to generate robust project schedules, which are less vulnerable to ... -
Robust Resource Investment Problem with Time-Dependent Resource Cost and Tardiness Penalty
( IEEE Computer Society , 2016 , Conference Paper)In this paper, the classical Resource Investment Problem (RIP) is extended to consider time-depended resource cost instead of time-independent resource cost. The problem is named as the Resource Investment Problem with ... -
Integrated TOPSIS-COV approach for selecting a sustainable PET waste management technology: A case study in Qatar
( Elsevier , 2022 , Article)In 2018, the global annual consumption of Polyethylene terephthalate (PET) bottles was approximately 27.64 million tons, with one million bottles sold worldwide every minute. Unmanaged PET bottles in the environment lead ... -
Optimization of design and operation of solar assisted district cooling systems
( Elsevier , 2020 , Article)The demand for air conditioning and cooling services is rapidly increasing worldwide. As cooling demand has high coincidence to occur in countries with high solar irradiation, the combination of solar thermal energy and ... -

Optimization models for a single-plant District Cooling System
( Elsevier , 2015 , Article)A District Cooling System (DCS) is an interconnected system encompassing a centralized chiller plant, a Thermal Energy Storage (TES) unit, a piping network, and clusters of consumers' buildings. The main function of a DCS ... -
Optimal planning of liquefied natural gas deliveries
( Elsevier , 2016 , Article)We investigate the problem of designing an optimal annual delivery plan for Liquefied Natural Gas (LNG). This problem requires determining the long-term cargo delivery dates and the assignment of vessels to the cargoes ... -
MIP models for minimizing total tardiness in a two-machine flow shop
( Palgrave Macmillan Ltd. , 2013 , Article)We propose compact mixed-integer programming models for the NP-hard problem of minimizing tardiness in a two-machine flow shop. Also, we propose valid inequalities that aim at tightening the models' representations. We ... -
Improved bounds for hybrid flow shop scheduling with multiprocessor tasks
(2013 , Article)In this paper, we investigate the problem of minimizing makespan in a multistage hybrid flow-shop scheduling with multiprocessor tasks. To generate high-quality approximate solutions to this challenging NP-hard problem, ... -
Optimal design and operation of conventional, solar electric, and solar thermal district cooling systems

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 ... -
Data of the design of solar assisted district cooling systems
( Elsevier , 2020 , Other)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. ... -
Exact approaches for routing capacitated electric vehicles
( Elsevier , 2020 , Article)We investigate a variant of the standard Capacitated Vehicle Routing Problem (CVRP), where each vehicle is powered exclusively by electricity stored in its rechargeable battery. Consequently, each vehicle should visit not ... -
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 ... -
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 ... -
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 ... -
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 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 ... -
