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 ...
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: ...
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 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 ...
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 ...
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 ...
Statistical analysis of bus transportation networks of Istanbul
(World Scientific Publishing Co Pte Ltd, 2016)
Transportation networks such as railway, airport and bus networks are the real-world networks whose inherent statistical properties characterize and differentiate the networks. In order to understand the network characteristics ...
Re-mining item associations: Methodology and a case study in apparel retailing
(Elsevier Science BV, 2011-12)
Association mining is the conventional data mining technique for analyzing market basket data and it reveals the positive and negative associations between items. While being an integral part of transaction data, pricing ...
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 ...
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 ...
