A Sensitivity-based Commonality Strategy for Family Products of Mild Variation, with Application to Automotive Body Structures
نویسندگان
چکیده
Identification of the product platform is a key step in designing a family of products. This article presents a methodology for selecting the product platform using information obtained from the individual optimization of the product variants. Under the assumption that the product variety requires only mild design changes, a sharing penalty vector (SPV) is derived by taking into consideration individual optimal designs and sensitivities of functional requirements. Commonality decisions are based on SPV values and the product family is designed optimally with respect to the chosen platform. An automotive body structure problem is used to demonstrate the proposed methodology. Variants are defined by changing the functional requirements they need to satisfy and/or the geometry of the associated finite element models.

Abstract: This paper illustrates how common platform (CP) strategy can contribute to the effectiveness of the supply chain through commonality. Through reviewing the related literature and the practical data, which are collected through observations in manufacturing, a mathematical model is set up. This model was developed for reducing cost of part commonality in SCM and solved it by simulate...
متن کاملEfficient Product Portfolio Reduction
1. Abstract A product portfolio can be defined as the set of artifacts marketed by a corporation in order to meet its customer’s needs. The proliferation of products in a company’s portfolio can create inefficiencies due to the greater complexity and the corresponding effort required to design and manufacture the set of products. A methodology for efficiently reducing the number of products thr...
متن کاملQuantitative platform selection in optimal design of product families, with application to automotive engine design
Product variants with similar architecture but different functional requirements may have common parts. We define a product family to be a set of such products, and refer to the set of common parts as the product platform. Product platforms enable rapid adjustment to changing market needs while keeping development costs and time-cycles low. In many cases, however, the individual product require...
متن کاملConcept design of Vehicle Structure for the purpose of computing torsional and bending stiffness
Automotive design engineers face the challenging problem of developing products in highly competitive markets. In this regard, using conceptual models in the first step of automotive development seems so necessary. In this paper, to make a body in white conceptual model, an engineering approach is developed for the replacement of beam-like structures, joints, and panels in a vehicle model. The ...
متن کاملDivergence and lifecycle offsets in product families with commonality
Commonality, or the reuse and sharing of components, manufacturing processes, architectures, interfaces, and infrastructure across the members of a product family, is an often leveraged strategy targeted at improving corporate profitability. Commonality strategies are widespread in the literature and in industrial practice, but a clear gap exists: The literature has a distinctly positive bias t...
