    The multi-perspective modeling method is an enhancement of enterprise modeling and will enable understandable, operational views ("perspectives") on sustainable value creation. The goal is to allow all stakeholders to make decisions towards the sustainability in their context, ranging from individual enterprise decisions up to cooperation strategies. As known, the sustainability is based on the environmental, economic and social dimensions. The energy and resource efficiency is an essential subset within the sustainability context that affects mainly the first two dimensions. This paper presents an enterprise modeling driven and supported analysis of energy and resource efficiency, which was performed at several small and medium sized enterprises. The experiences gained from this application case are described and their consequences for the multi-perspective modeling method are argued.

    Modelling is a broadly accepted analytic instrument and planning tool. Today, modelling is mainly applied for engineering and physics purposes and covers a short time horizon when compared to intergenerational justice. In parallel, sustainability is gaining increased importance for the industrial planning, because themes like global warming, child labour, and compliance with social and environmental standards have to be taken into account. Sustainability is characterized by comprehensively examining the three dimensions of economic, environmental, and social questions as well as their long-term perspective. Adequate indicators and an adaptation of modelling and simulation methods and procedures are necessary to evaluate the sustainability of industrial processes. A further challenge is the consideration of sustainability effects coming from the usual manufacturing process structure of a value creation network, in particular from cross-company cooperation and geographically distributed production. This article analyses the implications of those advanced tasks on the simulation technique and its application and proposes a conceptual framework for the modelling and simulation of such networks, which differentiates the effects of sustainability by the level of decision-making within enterprises.
