The SOD Modeling Method in CAD System for Hydraulic Fracturing PSS Dseign

This paper proposes a new type of product service system (PSS) design method named Service-oriented Design (SOD), the design method aim at building a service-based modeling system to totally satisfy customer demand. The mainline of SOD is customer demand acquire, service function and performance, service structure and service activity. Based on this method and its mainline, we propose a CAD system (Service Design System) that designer is able to design a service using this visible system. Through its application to business case such as hydraulic fracturing, the Service Design System was proven to support designer to design a steady and efficient service.
