Function and process modeling for integrated product and manufacturing system platforms

Artikel i vetenskaplig tidskrift, 2015

Manufacturing companies face increasingly tougher individual customer requirements that force them to revise conceptual solutions for the redesigning of products. This situation limits the reuse of ready-made components and requires physical changes to the manufacturing system. In these settings, platforms must be prepared with greater flexibility to allow development over time. The corresponding platform models need to include conceptual considerations for products and manufacturing systems. The literature advocates functional modeling to capture these considerations but applies it separately to either the product domain or to the manufacturing domain. Further, its relationship to manufacturing processes is not expounded. Thus, functional modeling falls short of its potential to facilitate the integrated development of products and manufacturing systems. This paper puts forth an integrated platform model using functional modeling to capture the conceptual considerations for products and manufacturing systems together with the manufacturing processes. The model is tested for consistency and then illustrated by studying a real case example from the automotive industry modeled according to the approach suggested. The example shows that the model facilitates an understanding of the design of products and their manufacturing systems, including functions shared across domains and across lifecycle phases. Thus, the model is proposed for the conceptual phase of designing, aimed at reusing and redesigning components, machinery, manufacturing processes and design solutions.
