论文摘要
我们讨论在其他科学中创建适当数学模型的几个方面。特别是，许多困难源于源系统的极大复杂性以及各种不确定因素的存在。我们说明了不确定性对已知消费者需求模型的影响。我们得出的结论是，并非每个不确定性都可以由随机变量表示，并且这些概念不是等效的。我们还讨论了不同信息概念在数学模型中的作用。我们提供了相当复杂的系统模型的其他说明性示例。
We discuss several aspects of creation of adequate mathematical models in other sciences. In particular, many difficulties stem from great complexity of the source systems and the presence of a variety of uncertain factors. We illustrate the effect of uncertainty on the known consumer demand model. We conclude that not every uncertainty can be represented by a random variable, and that these concepts are not equivalent. We discuss also the role of different information concepts in mathematical models. We give additional illustrative examples of models of quite complex systems.
