Algorithm of Inventive Problems Solving

Encyclopedia : A : AL : ALG : Algorithm of Inventive Problems Solving

ARIZ (russ. acronym of Алгоритм решения изобретательских задач) - Algorithm of Inventive Problems Solving is problem solving technique in form of list of (about 85) step-by-step procedures that incrementally evolves a complex problem to a point where it is simple to solve. See also Genrich Altshuller.

Complex problems cannot be solved in just two steps. For those problems which are so complex, that they cannot be solved with any other tools, TRIZ includes the algorithm to follow which will facilitate the problem-solving process. ARIZ is not an equation, but rather a multi-step process asking you a series of questions that integrates different pieces of TRIZ.

ARIZ is a very "solution neutral" (i.e. neutral to industry where problem emerged) process: i.e., it takes preconceived solutions out of the problem statement. It starts you at a position that assumes the nature of your problem is unknown. ARIZ reacquaints you with your problem by allowing you to see your problem with a fresh pair of eyes.

ARIZ features:

is a process of problem reformulations
is logical and disciplined
continually reinterprets the problem
is the main TRIZ method for solving conflicts

Principles of ARIZ

ARIZ utilizes:

Ideality [link] for an understanding of the Ideal Final Result (IFR or Ideal Solution) to the problem
Contradictions, by working first with the technical contradiction, then the physical contradiction
Logic of ARIZ [link]
Resources of the system
Scientific effects
S-field modeling and Standard Solutions or the 40 Principles

It is important to note that ARIZ is more than 50% problem reformulation! It is only through this guided reformulation that complex problems can be solved.

Framework for ARIZ

There are the nine classic steps (and the number of sub-steps vary from version to version of ARIZ). The three macro level processes with their respective nine "Classic" parts are:

I. Restructuring of the Original Problem

Analyze the System
Analyze the Resources
Define the Ideal Final Result and Formulate the Physical Contradiction

II. Removing the Physical Contradiction

Separate the Physical Contradiction
Apply the Knowledge Base: Effects, Standards, and Principles
Change the "Mini-Problem"

III. Analyzing the Solution

Review the Solution and Analyze the Removal of the Physical Contradiction
Develop Maximum Usage of the Solution
Review All the Stages in ARIZ in "Real Time" Application

ARIZ is used to solve very complicated invention problems, where other tools of TRIZ (Su-field analysis, 40 inventive principles, etc.) are not applicable.

History

There are several versions of ARIZ: 1977, 1985 and 1991.
