极限过程的不确定性表示

Representation of Uncertainty for Limit Processes

Mark Burgin

AI总结:

本文针对测量与计算中的不确定性,基于模糊极限概念提出数学方法,并用模糊导数替代常规导数以处理微分模型的内在不确定性。

摘要:

许多数学模型利用极限过程。连续函数与微积分、微分方程和拓扑学,都基于极限和连续性。然而,当我们进行测量和计算时,只能获得近似结果。在某些情况下,理论方案与实际操作之间的这种差异会极大地改变研究和决策的结果,从而导致知识的不确定性。本文基于模糊极限的概念,提出了一种针对计算和测量中出现的此类不确定性的数学方法。针对具有不确定性的微分模型,开发了一种数学技术。为了考虑模型的内在不确定性,建议在该模型中使用模糊导数代替常规的函数导数。

英文摘要:

Many mathematical models utilize limit processes. Continuous functions and the calculus, differential equations and topology, all are based on limits and continuity. However, when we perform measurements and computations, we can achieve only approximate results. In some cases, this discrepancy between theoretical schemes and practical actions changes drastically outcomes of a research and decision-making resulting in uncertainty of knowledge. In the paper, a mathematical approach to such kind of uncertainty, which emerges in computation and measurement, is suggested on the base of the concept of a fuzzy limit. A mathematical technique is developed for differential models with uncertainty. To take into account the intrinsic uncertainty of a model, it is suggested to use fuzzy derivatives instead of conventional derivatives of functions in this model.
