Functional Representation: from synthesis to evaluation of conceptual layouts
Konferensbidrag (offentliggjort, men ej förlagsutgivet), 2000

Functional decomposition is a key method for developing product architectures during conceptual design and it helps the designer from a problem definition to a conceptual layout. This paper identifies two strategies for functional decomposition; system decomposition, where the decomposition, at each level, describes the total system and ends with a conceptual layout at the lowest level; and decomposition by synthesis, where a mean/solution is stated at each level of decomposition and the sum of all means describes the conceptual layout. The functional decomposition methodology presented gives the possibility to represent design solutions and their emergent properties at different levels of complexity using a decomposition by synthesis strategy and using the taxonomy developed in systems decomposition to specify the interfaces between objects on the same hierarchical level. Finally, the methodology is exemplified during a case study where a security system of a car is modelled.
