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 simulation-optimization approach for robust aircraft routing
(
Universite de Lorraine
, 2015 , Conference Paper)
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 ...
Solving a large-scale crew pairing problem
(
Palgrave Macmillan Ltd.
, 2015 , Article)
Airline companies seek to solve the problem of determining an assignment of crews to a pre-determined flight schedule with minimum total cost, called the Crew Pairing Problem (CPP). Most of the existing studies focus on ...
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 ...
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 ...
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 ...
