由于组件的数量和/或其强烈的相互依赖性，许多热系统非常复杂。这种复杂性使得系统设计和操作的优化变得困难。能量成本理论基于资源、结构、效率和目的（属于任何生产理论）等概念和第二定律。本文将展示如何从火力成本理论中获得组件消耗的当地资源的边际成本（拉格朗日乘数）。本文还展示了所提出的扰动理论在以直接方式描述结构相互作用的复杂性时的优势。该理论允许制定简单的程序来对工厂中的组件进行局部优化。最后显示了复杂系统的优化策略。它们基于从组件到组件的顺序优化。这种清晰有效的方法源于我们现在有效应用热经济隔离原理的事实。
Many thermal systems are very complex due to the number of components and/or its strong interdependence. This complexity makes difficult the optimization of the system design and operation. The Theory of Exergetic Cost is based on concepts such as resources, structure, efficiency and purpose (belonging to any theory of production) and on the Second Law. This paper will show how is it possible to obtain from the theory of exergetic cost the marginal costs (Lagrange multipliers) of local resources being consumed by a component. This paper also shows the advantage of the proposed Theory of Perturbations when describing the complexity of structural interactions in a straightforward way. This theory allows to formulate simple procedures for local optimization of components in a plant. Finally strategies for optimization of complex systems are shown. They are based in the sequential optimization from component to component. This clear and efficient method comes form the fact that we have now an operative application of the Thermoeconomic Isolation Principle.
