  • 摘要: 为了探讨价值及相关概念的数学定义,根据价值是客体属性对主体需要的满足关系的原理,提出事物 wi 的价值的数学定义,阐释了同一事物对不同的主体有不同的价值取向的科学合理性。对事物的价值随着使用时间的增加而衰减的规律给出了数学表达。根据事物的价值衰减与其某些零部件的功能丧失的相关性提出了维修的定义,并从功能丧失的零部件的量变到质变的演化逻辑,推导了废品的定义。本文将价值及相关概念进行了定量描述,揭示了它们的数学本质和内在联系,有广泛的应用价值和解释功能。
  • To explore the mathematical definition of value and related concepts, based on the principle that value is the satisfaction of the object attribute to the subject’s needs, a mathematical definition of the value of wi is proposed, which explains the scientific rationality of the same thing with different values for different subjects. The mathematical expression is given to the law that the value decays as the usage time increases. According to the correlation between value attenuation and the loss of function of certain parts, the definition of maintenance is proposed, and the evolutionary logic of the quantitative change of the parts with loss of function to the qualitative change is derived from the definition of scrap. This article quantitatively describes values and related concepts, reveals their mathematical nature and internal connections, and has extensive application value and explanatory functions.
