Asymptotic approach for a renewal-reward process with a general interference of chance
(Taylor & Francis Inc, 2016)In this study, a renewal-reward process with a discrete interference of chance is constructed and considered. Under weak conditions, the ergodicity of the process X(t) is proved and exact formulas for the ergodic distribution ... -
Asymptotic Expansions For The Moments Of The Renewal-Reward Process With A Normal Distributed Interference Of Chance
(Ministry Communications & High Technologies Republic Azerbaijan, 2018)In this study, a renewal-reward process with a normal distributed interference of chance is mathematically constructed. The ergodicity of this process is discussed. The exact formulas for the nth order moments of the ergodic ... -
Asymptotic Properties of the Straight Line Estimator for a Renewal Function
(Univ Kebangsaan Malaysia, 2015-07)In estimation problems in renewal function, when the distribution is not known, nonparametric estimators of renewal function are used. Frees (1986a, Warranty analysis and renewal function estimation, Naval Res. Logist. ... -
Asymptotic Rate for Weak Convergence of the Distribution of Renewal-Reward Process with a Generalized Reflecting Barrier
(Springer-Verlag Berlin, 2016)In this study, a renewal-reward process (X(t)) with a generalized reflecting barrier is constructed mathematically and under some weak conditions, the ergodicity of the process is proved. The explicit form of the ergodic ... -
Asymptotic Results for an Inventory Model of Type (s, S) with Asymmetric Triangular Distributed Interference of Chance and Delay
(Gazi Univ, 2018)In this study, a semi - Markovian inventory model of type (s, S) is considered and the model is expressed by a modification of a renewal - reward process (X(t)) with an asymmetric triangular distributed interference of ... -
Automated robotic assembly line design with unavailability periods and tool changes
(Inderscience Enterprises Ltd, 2016)We focus on an assembly line design problem of a fully automated robotic spot-welding line. Different from existing studies, we take the prescheduled unavailability periods, such as lunch and tea breaks, into account in ... -
Bid price optimization for truckload carriers in simultaneous transportation procurement auctions
(Pergamon-Elsevier Science Ltd, 2015-03)We study simultaneous transportation procurement auctions from a truckload carrier's perspective. We formulate a stochastic bid price optimization model aimed at maximizing the carrier's expected profit. The model accounts ... -
The Class of L boolean AND D and Its Application to Renewal Reward Process
(Amer Inst Physics, 2018)The class of L boolean AND D is generated by intersection of two important subclasses of heavy tailed distributions: The long tailed distributions and dominated varying distributions. This class itself is also an important ... -
Comparative Analysis of Load-Shaping-Based Privacy Preservation Strategies in a Smart Grid
(IEEE-Inst Electrical Electronics Engineers Inc, 2017-12)A key enabler for the smart grid is the fine-grained monitoring of power utilization. Although such a mechanism is helpful in the optimization of the whole electricity generation, distribution, and consumption cycle, it ... -
A Comparison of Different Multi-Criteria Analyses for Electric Vehicle Charging Station Deployment
(RGN Publications, 2019)Scarcity in near future, and the price fluctuation of fossil fuels lead to many industries change their products that use these resources into more eco-friendly versions. One of the most recent and noticeable example of ... -
Comparison of stochastic and random models for bacterial resistance
(Springer International Publishing Ag, 2017-05)In this study, a mathematical model of bacterial resistance considering the immune system response and antibiotic therapy is examined under random conditions. A random model consisting of random differential equations is ... -
A copy-at-neighbouring-node retransmission strategy for improved wireless sensor network lifetime and reliability
(Taylor and Francis Ltd., 2018-11-18)A Wireless Sensor Network (WSN) is composed of tiny autonomous sensors with limited battery power. WSNs are employed to observe specific fields of interest. In this paper, we study the energy efficient and reliable network ... -
Cyclic Delivery Schedules for an Inventory Routing Problem
(Informs, 2015-11)We consider an inventory routing problem where a common vendor is responsible for replenishing the inventories of several customers over a perpetual time horizon. The objective of the vendor is to minimize the total cost ... -
Cyclic scheduling of parts and robot moves in m-machine robotic cells
(Elsevier Ltd., 2018-02-27)We consider a flow shop type manufacturing cell consisting of m machines and a material handling robot producing multiple parts. The robot transfers the parts between the machines and loads/unloads the machines. We consider ... -
A data-driven optimization framework for routing mobile medical facilities
(Springer US, 2018-09-20)We study the delivery of mobile medical services and in particular, the optimization of the joint stop location selection and routing of the mobile vehicles over a repetitive schedule consisting of multiple days. Considering ... -
Deterministic stability and random behavior of a Hepatitis C model
(Public Library Science, 2017-07)The deterministic stability of a model of Hepatitis C which includes a term defining the effect of immune system is studied on both local and global scales. Random effect is added to the model to investigate the random ... -
Electricity market structure and forecasting market clearing prices
(Springer, 2020)Electricity markets are evolving into a complex competitive business environment with an increasing role of the private sector in production, consumption, and retailing of electricity. Even transmission and distribution ... -
Empirical comparison of three models for determining market clearing prices in Turkish day-ahead electricity market
(IEEE, 2017)Bidders in day-ahead electricity markets want to sell/buy electricity when their bids generate positive surplus and not to take an action when the reverse holds. However, non-convexities in these markets cause conflicts ...
