Economic impacts of increased U.S. exports of natural gas: An energy system perspective
(MDPI AG, 2016-05-25)With the recent shale gas boom, the U.S. is expected to have very large natural gas resources. In this respect, the key question is would it be better to rely completely on free market resource allocations which would lead ... -
The economic lot-sizing problem with perishable items and consumption order preference
(Elsevier Science BV, 2015-08-01)We consider the economic lot-sizing problem with perishable items (ELS-PI), where each item has a deterministic expiration date. Although all items in stock are equivalent regardless of procurement or expiration date, we ... -
An effective maintenance policy for a multi-component dynamic system using factored POMDPs
(Springer Verlag, 2019-09-20)With the latest advances in technology, almost all systems are getting substantially more uncertain and complex. Since increased complexity costs more, it is challenging to cope with this situation. Maintenance optimization ... -
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 ... -
Failure analysis and warranty modeling of used cars
(Pergamon-Elsevier Science Ltd, 2011-09)Reliability is an important aspect of product perception and manufacturers are compelled to take corrective actions on the items failing within the warranty period. Automotive manufacturers are being exposed to significant ... -
Interdependent network restoration: On the value of information-sharing
(Elsevier Science BV, 2015-07-01)We consider restoring multiple interdependent infrastructure networks after a disaster damages components in them and disrupts the services provided by them. Our particular focus is on interdependent infrastructure restoration ... -
Investment in improved inventory accuracy in a decentralized supply chain
(Elsevier Science BV, 2008-06)It is known that inaccurate inventory records can lead to profit losses in a supply chain. Inventory records may not be correct due to various reasons such as transaction errors, misplacement, shrinkage, etc. In order to ... -
Limanlarda kullanılan iş makinelerinde risk analizi çalışması
(2017)Limanlar genellikle iş yerleri arasında çok önemli bir alanı kapsamaktadır. İçeriğinde ne olduğu kendilerince bilinmeyen yükler ile uğraşan çalışanların, geniş bir yelpazede makinelerle birlikte çalışarak görev yaptığı ve ... -
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 ... -
Maintenance policy simulation for a factored partially observable system
(The Society for Modeling and Simulation International, 2019-07)Taking maintenance decisions is one of the well-known stochastic sequential decision problems under uncertainty. Partially Observable Markov Decision Processes (POMDPs) are powerful tools for such problems. Nevertheless, ... -
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 ... -
Mobilya sektöründe pnömatik zımbalama ve vidalama işlerinin ergonomik risk değerlendirmesi
(2017)Uygun olmayan çalışma duruşları kas iskelet sistemi rahatsızlıklarına neden olduğu gibi, üretimdeki verimin de düşmesine yol açmaktadır. Dolayısıyla ergonomi disiplininin öncelikli amacı, çalışma koşullarını iyileştirerek, ... -
Multiresponse optimisation of powder metals via probabilistic loss functions
(Inderscience Enterprises Ltd, 2013)Quadratic loss functions have been used extensively within the context of quality engineering and experimental design for process and product optimisation and robust design. In general, this approach determines optimal ... -
MUNICIPAL: A decision technology for the restoration of critical infrastructures
(Institute of Industrial Engineers, 2013)This paper describes the decision technology MUNICIPAL (Multi-Network Interdependent Critical Infrastructure Program for the Analysis of Lifelines). This technology supports decision makers in the restoration of critical ... -
A nonparametric approach for optimal reliability allocation in health services
(Emerald Group Publishing Limited, 2016-02-01)Reliability evaluation of healthcare services has been a challenging task for both operations managers and system engineers working in the respective field. The purpose of this paper is to develop a data envelopment ... -
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 ... -
On the sensitivity of desirability functions for multiresponse optimization
(American Institute of Mathematical Sciences, 2008-11)Desirability functions have been one of the most important multiresponse optimization technique since the early eighties. Main reasons for this popularity might be counted as the convenience of the implementation of the ... -
