Assessing the efficiency of hospitals operating under a unique owner: a DEA application in the presence of missing data
(Inderscience Publishers, 2010-05)Originally developed in the late 1970s to assess the efficiency of comparable operating units, Data Envelopment Analysis (DEA) has since been used in a variety of contexts. Although incomplete data sets are often encountered ... -
Assortment optimization with log-linear demand: application at a Turkish grocery store
(Elsevier Ltd, 2019-09)In retail sector, product variety increases faster than shelf spaces of retail stores where goods are presented to consumers. Hence, assortment planning is an important task for sustained financial success of a retailer ... -
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 ... -
Cost-effective fault diagnosis of a multi-component dynamic system under corrective maintenance
(Elsevier Ltd, 2021-04)Maintenance planning and execution are challenging tasks for every system with complex structure. Interdependent nature of the components that builds up the system may have significant effect on system integrity. While ... -
A DBN based reactive maintenance model for a complex system in thermal power plants
(Elsevier Sci Ltd, 2019-10)Thermal power plants consist of several complex systems having many interacting hidden components. Any unexpected failure may lead to prolonged downtime and serious lost profits. Therefore, implementing an effective ... -
Developing an effective maintenance policy for control gates in hydroelectric power plants
(IEOM Society, 2018)Energy consumption has been increasing rapidly in the world. That is why production of energy from renewable resources is getting more and more important today. Hydroelectric power is the largest source of renewable ... -
Driving forces of Turkey's transportation sector CO2 emissions: An LMDI approach
(Elsevier Ltd, 2020-08-01)The transportation sector is one of the main contributors to global greenhouse gas (GHG) emissions. As the efforts towards emission mitigation increase, the expectation from the sector arises equally. In this analysis, the ... -
Dynamic frontier estimation for monitoring team performances: A case on Turkish first division football league
(Emerald Group Publishing Limited, 2019-06-10)Purpose: This paper aims to investigate how predictions of football league standings and efficiency measures of teams, obtained through frontier estimation technique, evolve compared to actual results. Design/methodology/approach: ... -
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 ... -
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 ... -
