During the last five decades, manufacturing has radically changed not only due to the technology development but also because of the new market and environmental requirements. Nowadays, companies are focused not only on cost-reduction and effectiveness or realized processes but also on reducing the negative impact on natural and social environment. Therefore, the maintenance is also transforming its role in order to better support value creation, both contributing to the economic dimension as well as extending its care for the environmental and social aspects. The paper presents a new method to solve the problem of the initial maintenance indicator merge into a new synthetic index that allows measuring the level of maintenance sustainability. The proposed approach allows to look at the process of combining indicators from a different perspective (i.e. through interactions between criteria) to help decision-makers in improving economic, social and environmental results of maintenance system. To justify effectiveness of proposed approach, it was applied to Composite Maintenance Sustainability Indicator, which was therefore generalized and expanded, so that it could be used in decision support system. The included case study shows the real benefit of using the proposed approach to analyse the actual results of maintenance system from sustainability point of view and forecasting future actions.

在过去的五十年中，制造不仅因为技术的发展而且由于新的市场和环境要求而发生了根本性的变化。如今，公司不仅专注于降低成本和有效性或已实现的流程，还致力于减少对自然和社会环境的负面影响。因此，维护也正在转变其作用，以便更好地支持价值创造，这不仅有助于经济发展，而且还扩大了对环境和社会方面的关注。本文提出了一种新方法，可以解决将初始维护指标合并为新的综合指标的问题，该指标可以衡量维护可持续性的水平。所提出的方法允许从不同的角度（即通过标准之间的相互作用）看待指标组合的过程，以帮助决策者改善维护系统的经济，社会和环境成果。为了证明所提出方法的有效性，将其应用于综合维护可持续性指标，因此对其进行了概括和扩展，以便可以将其用于决策支持系统。所包括的案例研究显示了使用所提出的方法从可持续性的角度分析维护系统的实际结果并预测未来行动的真正好处。它被应用到了“综合维护可持续性指标”中，因此得到了推广和扩展，以便可以在决策支持系统中使用。所包括的案例研究显示了使用所提出的方法从可持续性的角度分析维护系统的实际结果并预测未来行动的真正好处。它被应用到了“综合维护可持续性指标”中，因此得到了推广和扩展，以便可以在决策支持系统中使用。所包括的案例研究显示了使用所提出的方法从可持续性的角度分析维护系统的实际结果并预测未来行动的真正好处。
