Development operations of Automotive. Built an environment that allows anyone to carry out simulations to check performance and reliability easily, before creating the prototype based on the blueprint. Improved the product competitiveness and development speed of the motor vehicle.

Makes Complicated Performance Simulations Easier for Anyone

Simulations become Executable by the Developers themselves!

Q. What kind of operations do you use Questetra for?

Fuji Heavy Industries is a transportation equipment manufacturer with a focus on automotive manufacturing.

In Automotive business, we develop, manufacture and sale cars under the brand of “SUBARU” such as “Legacy”, “Impreza”, and “Forester”, on the concept of “Enjoyment and Peace of Mind”.

We are utilizing Questetra in the improvement of the simulation efficiency of Automotive engine development operations.

Q. How did you achieve the improvement of the efficiency?

Development of engines consist in the repetition of Blueprint drawing, Prototyping, and Performance and Reliability evaluations. However, the performance and reliability evaluations are now available to do virtually by simulation technology developed recently. Thanks to that, it is now possible to obtain more information to improve the product competitiveness faster than when evaluating through prototyping.

On the other hand, developers need to ask experts to run the simulations, for these simulations require complicated operations and expertise.

Hence, we are promoting the automatization of simulation, thinking that ‘It will be better and faster if the developers are capable to exercise their creativity and do the simulations by themselves’. We are using the Questetra as a management control tool for it.

Also for Sharing Information among Engineers!

Q. What are the main characteristics of the mechanisms for which you use Questetra?

Automation of simulation has been addressed in various ways, but most of them are developed as mere tools.

We put emphasis on the availability of information sharing between the developers and the simulation expert that would complement each other. Therefore, we have arranged the Tasks for the developers and for the simulation experts alternately on the Workflow, so that communications between them to be raised.

In addition, taking advantage of the characteristics of human-centric BPM, we have schemed to allow distributed processing of operations by considering to enable the division of labor even within each department.



Q. Do you have any suggestions for Questetra?

Up until now, in the automation of simulation, only the function was focused and its operations were left to humans. Because we are able to visualize the Workflow, we are able to operate as it was defined by using Questetra, now all of us can discuss both of the aspects of function and operation.

Meanwhile, in order to promote the further automation of simulation in the future, it is necessary to increase the people who are capable of drawing the workflow. I guess the easier the Process Modeler becomes, the more people can draw a Workflow. (For examples if features of test running the process model or replicating any part flow could be achieved.)
