Performance analysis of an aggregation and disaggregation solution procedure to obtain a maintenance plan for a partially observable multi-component system
(Elsevier Sci Ltd, 2017-11)
We analyze the performance of an aggregation and disaggregation procedure in giving the optimal maintenance decisions for a multi-component system under partial observations in a finite horizon. The components deteriorate ...
The two-level economic lot sizing problem with perishable items
(Elsevier, 2016-05-01)
We present an economic lot sizing model of a supply chain for the procurement and distribution of a perishable item. We assume that the consumers always buy the item that lasts longer. We show that determining optimal ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
