This presentation was made at the NAFEMS Americas Seminar "Model-Based Engineering: What is it & How Will It Impact Engineering Simulation" held on the 1st of October 2019 in Columbus Ohio Resource Abstract BACKGROUND: The benefits of Modeling and Simulation (M&S) are well known and documented both within Medtronic and in external literature. However, there is a question concerning the most efficient means to organize the inclusion of M&S into the product development cycle. We tested the hypothesis that a hybrid development process (PDP) involving both Empirical and M&S methods in Centralized or Decentralized organizational structures lead to improvements in throughput and resource utilization....more
This Presentation, DoES Theme: ASSESS Working Session Report 2018 (Session 2), is from 2018. NAFEMS & ASSESS members can view / download when logged in. The ASSESS Initiative is a broad reaching multi-industry initiative with a primary goal to facilitate a revolution of enablement that will vastly increase the availability and utility of Engineering Simulation, leading to significantly increased business benefits across the full spectrum of industries, applications and users. Since June 2022, ASSESS as been part of NAFEMS....more
Advantages to verifying ultimate limit state (ULS) by numerical simulation include the checking of multiple failure forms that are not pre-determined and more accurate constitutive modelling. However, geotechnical simulation is particularly challenging due to the high non-linearity of ground constitutive behaviour and interactions with stiff structures. The next generation of the European geotechnical design standard Eurocode 7 will be the first to cover numerical simulation specifically and this webinar will provide an overview of the new rules and the reasoning behind them, together with worked examples....more
Product and System Optimisation Incorporation of Product and System Optimization (PSO) Methods into Compact, Reliable Design Cycles Workshop Description This workshop is concerned with educational & awareness issues, including identifying barriers to successful uptake of emerging and relatively mature technologies. The workshop will be structured into two parts, a discussion session where issues are identified and technical presentations where specific methods are presented along with summaries of state of the art. The technical focus for this workshop is Design of Experiments and Response Surface Analysis. The workshop will also address the following questions: • What are the...more
How to Perform Optimisation Under Uncertainty This NAFEMS publication, contributed by the ESTEcO engineering software company, focuses on Design Optimisation Under Uncertainty (OUU) methods. Further valuable insights on OUU are provided by the Dynardo engineering software company in a companion NAFEMS publication Irobust Design Optimization in Virtual Product Development" by Johannes Will. This publication provides: a) a description of the Smoothing Spline ANOVA (SSYANOVA) screening method, b) a comparison of Uncertainty Quantification (UQ) methods: sample based and Polynomial chaos Expansion (PcE), c) and a description of robust Design Optimisation (rDO) and reliability Based...more
Stochastics Publications A key activity of all of NAFEMS working groups is to produce best practice and guidance documents. To date, a number of publications have been produced which will benefit novices and experts alike. Below is a list of NAFEMS current stochastics publications. What is Uncertainty Quantification (UQ)? Challenges In Uncertainty Quantification Stochastics and its Role in Robust Design...more
Simulation is changing how we design and bring products to market, creating competitive advantages for companies that take advantage of these advances. We’ll talk about what we can expect in the evolving world of simulation— and ask essential questions to help you navigate these changes. Monica Schnitger - President and Principal Analyst, Schnitger Corporation...more
Abstract The successful introduction of a simulation data management system is a complex matter and is subject to a large number of influencing variables and dependencies. Due to the time horizon, some of these variables are in a perpetual state of change and determine the course of the integration. We divided the implementation into four phases. Initially, the needs and potentials of the business units were determined and, based on these, an appropriate SDM tool selection was made in the next step. In phase three, the SDM software was piloted in the working environment and is now being rolled out worldwide. The capability for integration into the existing and future IT landscape, including...more

7. Concluding Remarks Concluding Remarks Having got a valid result from the model, what should the engineer do next if the process has failed? The steps to be taken are outlined before a discussion of the role of optimisation in both parameter target setting and robustness evaluation. Quiz Previous chapter Next chapter...more
