Abstract

This paper represents a development process of product families in a case where already available designs are emphasized. This can be called as a brownfield process. Tools, which support the individual steps of brownfield development projects, do exist. In this paper it is described how these tools, methods and procedures can be used to cover a whole development process of a product family. The development of a product family was divided into five steps: setting of goals, developing of a generic element model, analyzing the customer requirements, analyzing the minimum variation and describing the resulted product structure. In the first four steps existing tools were used. In the fifth step new description method, Product Structuring Blue Print (PSBP), for describing a product structure was represented. PSBP shows how items are related on assemblies, how modules include assemblies, how modules are realized, and what customer requirement is connected to each module. PSBP helps in creating the view of the significance of the product structure solution principles. PSPB gives also a response to how product structuring decisions have to be made.

Keywords: VARIABILITY; PRODUCT STRUCTURING BLUE PRINT; PRODUCT FAMILY
