The Covariance Function of a Regenerative Process
Regenerative process renewal function stationary process steady-state simulation
2015/7/8
In this paper, we develop regenerative representations for the covariance function of both a non-delayed regenerative process and a stationary regenerative process. These results are used to obtain co...
We investigate the question of when sampling a stochastic process X = {X(t): t≥0} at the times of an independent point process ψ leads to the same empirical distribution as the time-average limiting d...
Approximating Martingales for Variance Reduction in Markov Process Simulation
Variance reduction Markov process simulation martingale
2015/7/8
“Knowledge of either analytical or numerical approximations should enable more efficient simulation estimators to be constructed.” This principle seems intuitively plausible and certainly attractive, ...
Properties of the Reflected Ornstein-Uhlenbeck Process
diffusion approximation Ornstein–Uhlenbeck process refl ecting diffusion steady-state
2015/7/8
Consider an Ornstein–Uhlenbeck process with reflection at the origin. Such a process arises as an approximating process both for queueing systems with reneging or state-dependent balking and for multi...
Rare Event Simulation for a Generalized Hawkes Process
Rare Event Simulation Generalized Hawkes Process
2015/7/6
In this paper we study rare event simulation for the tail probability of an affine point process (Jt)t≥0 that generalizes the Hawkes process. By constructing a suitable exponential martingale, we are ...
Zero-Variance Importance Sampling Estimators for Markov Process Expectations
Importance sampling Markov process simulation
2015/7/6
We consider the use of importance sampling to compute expectations of functionals of Markov processes. For a class of expectations that can be characterized as positive solutions to a linear system, w...

This paper reviews the evolution of three general strategies for Knowledge Management (KM) in the context of the Product Development Process (PDP) Early Stages. The first strategy, "storage and mappin...
An introduction to the reference model for the agricultural machinery development process
engineering design project management product development process reference model agricultural machinery
2009/12/1
The majority of Brazilian industrial companies operating in the agricultural machinery
sector use an informal product development process. This is most apparent in small and medium
sized companies, ...
Applying virtual simulation in automotive new product development process

2009/12/1
The objective of this paper is to analyze the impact of virtual simulation use on Product Development Process (PDP). A comparative analysis was made between PDP “Traditional Model”(a name used specifi...
Best practice for selecting software to support NPD process management
NPD best practices tool selection reference model
2009/12/1
The use of software solutions is one way to improve NPD processes. However, this practice is still underestimated due to the lack of a comprehensive selection process of software toward the necessitie...
