Modularization of Product Service System Based on Functional Requirement

The customers need no longer just a physical product, but rather the required function provided by the offering of product and service, namely product service system (PSS). Modularization plays a key role in the PSS development in order to address and support individual conceptual design. Functional requirements of PSS can be identified and then classified into different clusters by using a fuzzy clustering algorithm. Considering the relationships between the products and services in a PSS with functional requirement clusters, PSS can be clustered into several modules. Through the modularization, PSS can be easily to customized design for meeting individual requirements. A numeral control machine case is used to show the validity and feasibility of the proposed method.
