Combining discrete and continuous simulation dynamo into simscript [PDF]

open access: yesProceedings of the 7th conference on Winter simulation - WSC '74, 1974
Discrete and continuous simulation can be combined in one program by using a discrete simulation language to simulate, among other things, a continuous simulation program. This amounts to the translation of the continuous language into the discrete language. The translation of Dynamo into Simscript is examined.

Estimation of heterogeneous preferences, with an application to demand for internet services [PDF]

open access: yes, 2005
This paper presents a structural econometric framework for discrete and continuous consumer choices in which unobserved intrapersonal and interpersonal preference heterogeneity is modeled explicitly.

Synchronization of Continuous Time and Discrete Events Simulation in SystemC

open access: yesIEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2021
Modeling and simulation of cyber-physical devices is difficult because of their heterogeneity: they mix discrete-event (DE) hardware and software with continuous time (CT) physical processes. DEs simulation progresses by discrete timesteps while CT simulation does so in a time continuum; despite different time representations, data must be transmitted ...

A comparison of mixed-variables Bayesian optimization approaches

open access: yesAdvanced Modeling and Simulation in Engineering Sciences, 2022
Most real optimization problems are defined over a mixed search space where the variables are both discrete and continuous. In engineering applications, the objective function is typically calculated with a numerically costly black-box simulation ...

Event Scheduling in Simulation of Discrete Event Systems with Application on Queuing Systems. [PDF]

open access: yesالمجلة العراقية للعلوم الاحصائية, 2010
Queuing theory and other of discrete and continuous event systems have theory aesthetic but the more assumptions which indepent these theories are not accurate as compared with real situation, also the queue problem is one of the most scientific problems

The Exponentiated Burr–Hatke Distribution and Its Discrete Version: Reliability Properties with CSALT Model, Inference and Applications

open access: yesMathematics, 2021
Continuous and discrete distributions are essential to model both continuous and discrete lifetime data in several applied sciences. This article introduces two extended versions of the Burr–Hatke model to improve its applicability.

Stronger computational modelling of signalling pathways using both continuous and discrete-state methods [PDF]

open access: yes, 2006
Starting from a biochemical signalling pathway model expresses in a process algebra enriched with quantitative information, we automatically derive both continuous-space and discrete-space representations suitable for numerical evaluation.

A Discrete-Time State Estimation for Nonlinear Systems With Noises

open access: yesIEEE Access, 2020
This paper proposes a discrete-time observer to estimate states of continuous-time nonlinear systems with presences of noises. Most conventional discrete-time state observers are designed using discrete-time models, which are derived by applying the ...
