Commonality Index of Outsourced Function Module Based on Generalized Dice Coefficient

Article Preview

Abstract:

Commonality analysis is the starting point of product family redesign, providing guidance for enterprises to improve commonality, reduce product cost and manufacturing complexity. Firstly, the component-based commonality indices introduced so far are analyzed and the deficiency in respect to commonality evaluation of outsourced function module is indicated. Then, the generalized performance matrix of outsourced function module is established and the commonality index based on generalized Dice coefficient is introduced. Finally, the calculation process is demonstrated by a case study of engine modules. The proposed index is of certain significance to reduce the types of outsourced module instances, save procurement and management cost and reduce the complexity of manufacturing systems.
