摘要

工业社会的建设可以看作是一个自组织的过程,社会中的熵减少,而通过能量耗散到环境中的熵相应增加。该过程是由高质量能量“退化”为低质量热量驱动的,因为能量沿着势梯度流动,同时产生有利的势梯度来驱动反应。后工业社会的特点是复杂性的增加,这可以通过能源消耗来监测。在这里,第一次尝试是将一些产品的复杂性(由其功能部件的数量表示)与它们的实际经济价值联系起来。

Entropy and the cost of complexity in industrial production

The building of an industrial society can be viewed as a process of self-organisation with a decrease in entropy in society and a corresponding increase of entropy through dissipation of energy into the environment. The process is driven by the “degradation” of high quality energy to low-quality heat as energy flows down potential gradients at the same time creating a favourable potential gradient driving the reaction. The post-industrial society is characterised by an increase in complexity, which can be monitored by the exergy consumption. Here a first attempt is made to relate the complexity of a number of products, as represented by the number of their functional parts, to their actual economic value.
