A quantitative model of universalization, serialization and modularization on equipment systems

Universalization, serialization and modularization are the three most important metrics in standardization of manufacturing. Developing with innovation of modern large-scale industrial production, a variety of methods were proposed to help enterprises to improve products' applicability, prevent trade barriers, and promote technical cooperation. Meanwhile, some metrics were designed to evaluate or optimize these standardized procedures. However, no systematically quantitative model has been proposed to evaluate the standardization of equipment so far. In order to break the barrier, a quantitative analysis based evaluation model of equipment system is proposed in this paper, in which, universalization, serialization and modularization indices are defined based on heterogeneous information network. Comparing the results performed by the proposed model with experts' evaluation, the metrics in proposed model can reveal the objective standardization of equipments.
