Abstract:

“Clarifying problem” is the premise of solving a problem. However, in reality, the problem is often vague and chaotic at the beginning. It is difficult to recognize the structure and relationship of the problem, which brings great confusion to the solution of the problem. “Clarifying problem” refers to the process of identifying the internal elements, internal relationships and the external factors, external relationships of a problem, for the purpose of structuring the problem. However, there exists no formal and operational method for the “clarifying problem”. In this paper, a formal, systematic and structural analysis method of “clarifying problem” is put forwarded by using the process of structural modeling. The process of clarifying the problem is accomplished through the interactive top-down advancement of the questioning system and the relying system, hence it is named “double descent spiral method” (DDSM). The application of the method is illustrated with the example of improving the evaluation form of science fund.

Key words: clarifying problem, structural modeling, system analysis, double descent spiral method, science foundation
