Call – Sensitivity Analysis for Model Quality

lilsensitivitaetsanalyse_header

Background & addressed challenge

 

Sensitivity Analysis represents a major step in simulation technology, irrespective of the underlying industrial sector. It enables engineers to obtain results on model quality, i.e. it gives answers to the following questions:

·       How well does the model depict the real system?

·       How likely is the real system to fail?

·       How do changes of model parameters affect model quality?

Modelling & Simulation often infers huge efforts in terms of costs and time, and thus significantly slows down system development. Our goal is to offer technologies to support engineering in modelling and simulation activities for documented confidence in simulation artefacts, leading to strictly mandatory quality measures for virtual system development.

 

Offered technology

 

Almost needless to say, system simulation always comes with uncertainties. For instance, measurement technology cannot overcome certain errors and some system parameters will always remain unknown. Our goal is to find input parameters that offer a good description of the model, keeping in mind the huge cost in time that simulation may infer.

To obtain results as soon as possible we offer a sensitivity analysis tool and service that

·       generates adequate samples of input parameters

·       runs simulations with given input

·       performs analysis on the system, given input and simulation results and

·       generates confidence reports for Modelling & Simulation engineers.

 

Our focus lies on correct sampling and analysis. Our methods aim to determine

·       possible weaknesses in the parameters setting

·       critical parameters concerning system failure and

·       failure probability of the real-world system given uncertainty measures of real-world performance data.

We aim to analyse the model automatically to give hints on parameter optimization to engineers. Furthermore, we manage to identify bad system models as soon as possible and may hence identify unprofitable development steps beforehand.

 

Experiment scope

 

We are seeking for industrial Modelling and Simulation applications where uncertainties in the model structure and model parameters are critical to the performance of related products. By the application of available Sensitivity Analysis tools and services uncertainties and confidence levels are identified for underpinning model and simulation quality measures.

Based on your industrial application, we first need to identify the required precision of the model output and hence need to estimate the distribution of the input parameters. Output data are generated by multiple simulations with data from the input sample. To keep the number of simulations small, we aim to approximate the distribution of the output. Hence, we require a thorough analysis of the model with technologies in Sensitivity Analysis (SA) that have already been proven successful in other areas. Those technologies may include python SALib package as well as cross-validation methods.

A concluding evaluation of the refined technologies in the form of a statistical experiment on the model from automotive development should lead to a publication.

The expected outcome of the experiments is further development of ideas and publication.
