We are currently running an experiment for which we need participants that are willing to contribute aproximately 20 to 30 minutes of their time. All participants (unless they protest, of course) will be entered into a price draw for 3 amazon vouchers for 25 Euro value each. Thanks if you are considering to take part! Please contact Insa Fuhrmann for one of the time slots from 18th to 25th of January: 0431-880-7526 or in person in room 1113. Also contact Insa Fuhrmann if you have questions that are not answered below.

The participants will be asked to give information on how experienced they are with modeling SCCharts and modeling and programming in general.

The participants will be given an SCChart model in Kieler together with a timing specification for the maximal worst case execution time of the model. The model in its given form does not meet the timing specification and it is the task for the participant to revise the model such that the timing specification is met. To be able to do that the participant will receive a list of alternative library functions for the host code calls that are included in the model. To replace function calls by calls to the respective alternative functions is the only change that is allowed to solve the task. However it is allowed to change the model temporarily, especially by commenting out parts of the code, but the outcome must be the same model (semantically as well as syntactically) with the exception of a number of swapped host code calls.

The participants will be devided into groups that will work with KIELER versions with different degrees of interactive timing support. We will measure the time it takes for each participant to solve the task as well as the number of call replacements. We will also document the final state of the model.

Here is a small example to illustrate the work process (please note that the actual model for the experiment will be larger than the example!):
