Scheduling and simulation of maritime traffic in congested waterways: An application to the Strait of Istanbul
(Cambridge University Press, 2021-05)
The aim of this study is to develop a simulation model which is capable of mimicking actual vessel arrival patterns and vessel entrance decisions (which are made based on expert opinions generally) on congested, narrow ...
A note on "The economic lot sizing problem with inventory bounds"
(Elsevier Science BV, 2012-11-06)
In a recent paper, Liu [3] considers the lot-sizing problem with lower and upper bounds on the inventory levels. He proposes an O(n(2)) algorithm for the general problem, and an O(n) algorithm for the special case with ...
Sensitivity analysis for models with multiple behavior modes: a method based on behavior pattern measures
(JUL-DEC 20)
Sensitivity analysis of system dynamics models is essentially about sensitivity of patterns of output behaviors to inputs, since system dynamics modeling is behavior pattern oriented. In this study, a regression-based ...
Optimal project duration for resource leveling
(Elsevier Science BV, 2018-04-16)
Resource leveling is important in project management as resource fluctuations are costly and undesired. Typically, schedules with better resource profiles are obtained by shifting the activities within their float times ...
A mathematical model for perishable products with price- and displayed-stock-dependent demand
(Elsevier Ltd, 2016-12)
We introduce an economic order quantity model that incorporates product assortment, pricing and space-allocation decisions for a group of perishable products. The goal is to maximize the retailer's profit under shelf-space ...
Minimization of rest mismatches in round robin tournaments
(Pergamon-Elsevier Science Ltd, 2018-11-01)
In sports tournaments, an occurrence of a difference in the rest periods of opponent teams in a game, which we refer to as a rest mismatch, will disadvantage the less rested team. Thus, it is only fair to expect opposing ...
Evaluation of proactive maintenance policies on a stochastically dependent hidden multi-component system using DBNs
(Elsevier Ltd, 2021-07)
In complex systems with stochastically dependent components which are not observed directly, determining an effective maintenance policy is a difficult task. In this paper, a dynamic Bayesian network based maintenance ...
Challenges in the CO2 emissions of the Turkish power sector: Evidence from a two-level decomposition approach
(Elsevier Ltd, 2021-06)
Decarbonization of the energy system is urgent to avert the disruptions in the climate. Considering its share, the low carbon transition of the power sector is pivotal. Growing electricity demand poses unique challenges ...
Maintenance policy analysis of the regenerative air heater system using factored POMDPs
(Elsevier Ltd, 2022-03)
Maintenance optimization of multi-component systems is a difficult problem. Partially Observable Markov Decision Processes (POMDPs) are powerful tools for such problems under uncertainty in stochastic environments. In this ...
