Designing information models objects at different levels of the hierarchy

The complexity of design tasks determined by the power of the set of technical solutions [1-4]. The tasks of designing I.P. Norenkov vary in levels of difficulty [1]. The first level of complexity are problems in which solutions are given and there is no synthesis. The second level of complexity of a variety of different possible technical solutions for the availability of resources to analyze, evaluate and select the best option based on their performance. The third level of difficulty include problems with many possible technical solutions with a deficit of resources for analysis and evaluation of all possible options, so that part of the options have to be excluded without detailed analysis. Thus, the third level of complexity tasks are converted to second.
