Set-based development using an integrated product and manufacturing system platform

Abstract

A platform is commonly used as a basis for generating a number of derivative products, after which it is replaced by a new platform. For some companies, a more viable approach is to adopt a continuous platform that is sustained and expanded over time. This applies to companies that have to provide highly customized products while not in control of interfaces, suppliers in the aerospace industry, for example. For them, the traditional part-based generation of platforms is not sufficient, and more flexibility must be built into the platform. This article proposes an approach for continuous platform development, based on an integrated artifact model and connected development processes. The processes apply set-based concurrent engineering to develop derivative products and to extend the bandwidth of the platform. The artifact model serves as a basis for development and connects products and manufacturing systems to enable informed design decisions that span across the lifecycle. The proposed approach incorporates two modes of platform use. Mode I is applied for configuring products to order within the bandwidth of the platform. This includes automatic concept evaluation using a pallet of computer-aided engineering tools and supporting tools. Mode II is applied when the bandwidth does not suffice to cover the required functionality and therefore needs to be expanded. This article exemplifies the approach through a case from a supplier in the aerospace industry.
