In many optimization problems the object realizes not one but many tasks of similar or different nature. But in practice multitask objects are being reduced to monotasked by assuming of "computational task", arbitral by rule. It can be proved, that for majority of real technical problems computational task does not exist(1), (2). Thus using of the one leads to false specialization of the object. Considering the multiplicity of tasks involves necessity of criteria formulation, which makes possible to evaluate common (total) task realization using component task local effectiveness. Mostly the criterion is equal to average (seldom weighted average) of local effectiveness. The expert evaluations are being used in case that evaluation is not satisfactory. The possibility of obtaining more complex valuation of realization of set of tasks in airplane design and some examples are presented.
