ARIZ
ARIZ is the Russian acronym for Алгоритм решения изобретательских задач. This means in analogous translation : " Algorithm or step procedure for solving the invention problem" and is a method that is used in the context of the TRIZ process. The method was first presented by Genrich Altschuller and Rafael Shapiro in 1956 and gradually developed by Altschuller until 1985.
ARIZ is an algorithm for generating ideas consisting of a list of around 85 step-by-step procedures . The method is used to very complex problems to solve with ideas where other methods are inadequate.
history
There are different versions of ARIZ, u. a. from the years: 1961 , 1977 , 1985 and 1991 .
methodology
Here in a fairly early version, the so-called ARIZ-61:
Analytical phase
- Define the problem
- Describe the ideal end result (IER)
- Define contradictions that oppose the realization of the IER
- Analyze the origin and causes of the contradictions
- Define conditions for overcoming the contradictions
Operational phase
- Check all possible changes in parameters and technical characteristics
- Check the possibility of dividing into independent subsystems:
- Isolate a “weak” and / or a “necessary and sufficient” subsystem
- Divide the object into similar and / or functionally differentiated subsystems
- Check possible changes in the respective environment of the object and its parameters:
- Divide the object environment into parts with different properties
- Use the externalities to perform desired functions
- Check possible changes in procedures in conjunction with the given technology:
- Investigate the connection of previously independent technical systems to a functioning overall system
- Remove one process and transfer its functions to another
- Increase the number of simultaneous process steps (e.g. in the case of an area by using the free rear side of this area)
- Examine examples from other branches of science, technology, and business of how the present trade-off was resolved in other disciplines
- Return to the original question and formulate the conditions in a more general way or switch to a more familiar task if the previous steps were unsuccessful
Synthetic phase
- Change the shape of the considered (technical) system
- Change the other procedures related to the system under consideration
- Change the procedure when using the technique under consideration
- Check the use of a found principle to solve another (technical) problem
