Сначала системный анализ базировалс

Сначала системный анализ базировался главным образом на применении сложных математических приемов. Затем стала вырабатываться концепция такого системного анализа, в котором упор делается преимущественно на логику и упорядочение процедуры принятия решений.
При таком подходе подчеркивается неразрывная связь системного анализа с принятием решения, означающим выбор определенного образа или курса действий среди нескольких возможных альтернатив.

First systematic analysis was based mainly on the use of sophisticated mathematical techniques. Then became produced the concept for such a systemic analysis, which focuses primarily on logic and the streamlining of decision-making procedures. Such an approach emphasizes the inextricable link system analysis with the adoption of the decision, meaning the selection of a specific image or course of action among several alternatives.
