Application name:

Case Study Production Cell

Organisation:

Forschungszentrum Informatik Karlsruhe (Research Center for Computer Science, Karlsruhe, Germany).

Method:

Comparative case study. Currently (November 1994) 21 different methods have been used, others are invited to join.

Tools:

Several, depending on the method used.

Domain:

Robotics

Period:

1993 -

Size:

Length of specifications differ between 300 and 3000 loc, effort between one person week and two person months.

Description:

Aim of the case study is to develop control software for a real world production cell. The production cell serves to forge metal blanks and can be controlled using 14 sensors and 13 actuators. A number of safety and liveness properties have to hold. The case study is realistic, of medium complexity (about 10^15 to 10^22 states, depending on the granularity of the model), and is a good example of the application of formal methods.

Conclusions:

The case study showed both limitations and benefits of formal methods. This is documented in detail in the below mentioned references.
