"Линейные" refers to linear concepts or structures, often used in mathematics and physics. In mathematics, linear equations represent relationships where a change in one variable results in a proportional change in another. This concept is fundamental in algebra and is used to describe straight lines on a graph. In a broader context, "линейные" can also describe processes or systems that follow a straight path or sequence. For example, in project management, linear planning involves a step-by-step approach, where each phase depends on the completion of the previous one. This method contrasts with more complex, non-linear approaches that allow for multiple pathways and outcomes.
