A field study of the industrial modeling process

Abstract

This paper analyzes the modeling process by means of a eld study in the chemical industries. A diversi ed set of experienced modelers from two di erent countries have been interviewed using a case study approach. The interviews focussed on the modeling process. Other issues like life-cycle perspectives and the use of modeling in the process industries were treated as well. The information has been summarized and presented in a structured manner imposing the least possible bias from the authors. Based on the interview information the modeling process is discussed in detail. Further, fundamental research issues are identi ed, and a research agenda is proposed.

Exploring the model development process in discrete-event simulation: insights from six expert modellers

“…He reports that approximately 40% of the time is spent on modelling, 20-30% on experimentation and 30-40% on pre-modelling and post-experimentation. Foss et al (1998) interviewed expert modellers on their practice of developing simulation models. Their results suggest that modelling is a creative activity dependent on personal style, background and characteristics of the modeller.…”

Application of Uncertainty and Sensitivity Analysis to a Kinetic Model for Enzymatic Biodiesel Production

“…To help improve the modelling process Foss et al (1998) investigated the process of model development in chemical industries and laid out some guidelines to improve modelling technology. More recently Heitzig et al (2011) proposed a generic methodology that structures the process of model development and analysis.…”

Exploring the Context and Practices of Expert Simulation Modellers

“…Arguably, these quantitative studies have provided useful indicators to understand characteristics of modellers and their backgrounds; nevertheless, these studies do not provide deep insights into their practices. We have, however, found a few in-depth studies looking at the practices of modellers under an experimental setting which includes Tako and Robinson [12], Willemain [13], Wang and Brooks [14], and Foss et al [15]. Each study is described briefly below.…”

“…Foss et al [15] interviewed 16 expert modellers from Germany and Norway working in process industries. In this study, instead of giving them a standard case study, the participants were asked to discuss how they had developed a model for a particular problem in the past.…”
