过去，资源的可持续利用和废物的减少主要是从生态的角度来看待的，而最近，资源效率越来越成为节约成本的问题。在系统地减少制造过程中的资源消耗之前，有必要量化所需的资源量，确定主要消费者并确定减少的可用自由度。模拟可以是一个足够的工具，但是，大多数可用的模拟方法不适合这项任务。因此，在生产工程和计算机科学的密切合作下，正在开发一种新的方法来量化和数值优化制造过程链的资源消耗。特别是，资源电能，原材料，冷却润滑剂和刀具磨损被考虑在内。本文以电能消耗为例，提出了一种新的系统理论方法--系统实体结构框架（SES），用于在元模型中定义与特定制造任务无关的替代制造序列和参数集。此外，模型库被用作存储每个相关制造过程的特定模型的库。所谓的基础模型的概念是基于离散事件仿真。该模型可用于加工过程建模，生成工件的资源消耗曲线和占用空间，并通过搜索和优化算法对元模型中的制造工艺和参数集进行有效组合，以满足用户特定的制造任务。优化结果是工艺链的参数和结构优化模型，可用于真实的规划任务。
Whereas in the past the sustainable use of resources and the reduction of waste have mainly been looked at from an ecological point of view, resource efficiency recently becomes more and more an issue of cost saving as well. Before resource consumption in manufacturing processes can be reduced systematically it is necessary to quantify the amount of resources needed, to identify major consumers and to determine the available degrees of freedom for a reduction. Simulation can be an adequate tool; however, most of the available simulation methods are not suitable for this task. Therefore in close cooperation of production engineering and computer science a new method is being developed to quantify and numerically optimize the resource consumption of manufacturing process chains. In particular, the resources electrical energy, raw material, cooling lubricants and tool wear are taken into consideration. The concept will be demonstrated exemplary in this paper for the consumption of electrical energy.A new, system theoretical approach, the System Entity Structure framework (SES) is utilized to define alternative manufacturing sequences and parameter sets independently of a specific manufacturing task in a meta-model. Furthermore, a model base is used as a library to store specific models for each relevant manufacturing process. The concept of the so-called basis models is based on the discrete-event simulation. It has been adapted to model machining procedures and to generate workpiece-specific resource consumption profiles and footprints.A search and optimization algorithm is able to examine valid combinations of manufacturing processes and parameter sets in the meta-model for user-specific manufacturing tasks. The optimization result is a parameter and structure optimal model of the process chain which is transferable to the real planning task.
