Accelerated Simulation of Discrete Event Dynamic Systems via a Multi-Fidelity Modeling Framework

Applied Sciences, 2017
Simulation analysis has been performed for simulation experiments of all possible input combinations as a “what-if” analysis, which causes the simulation to be extremely time-consuming.

Implementing and continuity of lean construction using discrete event simulation [PDF]

Journal of Structural and Construction Engineering, 2019
The success of lean principles in manufacturing and the benefits arising from its use is one of the main motivations for adopting lean principles in construction .The lean construction strives for the same goals as lean production, namely to eliminate ...

Multimodal Mechanical Testing of Additively Manufactured Ti6Al4V Lattice Structures: Compression, Bending, and Fatigue

Advanced Engineering Materials, EarlyView.
In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting

3D‐Printed Serial Snap‐Through Architectures for Programmable Mechanical Response

Advanced Engineering Materials, EarlyView.
A serial snap‐through architecture is realized using compact 3D‐printed von Mises truss units arranged in a staged cascade. Their geometry and boundary conditions program multistage mechanical responses with plateaux and re‐hardening regimes. An inverted‐compliance model predicts these behaviors and enables analytical design of programmable force ...

A Fast Discrete Event Simulation Model for Queueing Network Systems [PDF]

EAI Endorsed Transactions on Industrial Networks and Intelligent Systems, 2016
Based on Lindley's recursive equations for G/G/1 systems, this paper proposes a Fast Discrete Event Simulation (FDES) model for queueing networks. Equations for multiplexer and de-multiplexer elements are presented, which allows to simulate not only
