本文针对制造业中中小型企业(SME)评估网络物理系统(CPS)的成本效益所面临的挑战。CPS是实现生产过程数字化和互联的关键技术，具有提高生产效率和灵活性的优势。然而，由于复杂的CPS组成部分的各种成本以及对CPS潜在收益的模糊估计，很难正确评估CPS对利润增长的贡献。对于中小企业来说，由于缺乏具有CPS能力的人力资源和有限的财务资源，对CPS的投资决策尤其困难。因此，本文提出了一种评价中小企业合作伙伴关系经济效益的评价模型。为了评估效果，对不同成本类型的实施CPS进行了识别和分类。并对CPS利用的潜在效益进行了综合分析，提出了效益货币化的计算规则。指标“CPS回报率(RoCPS)”被定义为根据投资资本对利润进行估值。RoCPS将促进选择经济高效的CPS解决方案，通过合理的技术管理支持中小企业的经济增长。最后，通过一个电动汽车初创企业的用例对该评价模型进行了验证。
This paper addresses the challenge of evaluating the cost effectiveness of cyber-physical systems (CPS) for small and medium-sized enterprises (SMEs) in manufacturing industries. CPS are key technologies to implement the digitalization and interlinking of production processes with the advantage of increasing production efficiency and flexibility. However, it is difficult to evaluate properly how much CPS can contribute to profit growth because of various costs of complex CPS components and ambiguous estimation of potential CPS benefits. For SMEs, the investment decision on CPS is especially difficult due to the lack of human resources with CPS competence and limited financial resources. Thus, an evaluation model for assessing the economic effectiveness of CPS aimed at SMEs is developed in this paper. To assess the effectiveness, different cost types of implementing CPS are identified and classified. Furthermore, potential benefits of CPS utilization are analyzed comprehensively and calculation rules for monetization of benefits are suggested. The metric "Return on CPS (RoCPS)" is defined to value the profit based on the invested capital. The RoCPS will facilitate the selection of economically efficient CPS solutions, supporting SMEs with economic growth by reasonable technology management. Finally, the evaluation model is validated by a use case of an electric vehicle start-up.
