Representing systems through object-process methodology and axiomatic design

Abstract

Object-Process Methodology and Axiomatic Design are presented as two fundamentally different methods for representing systems. Strengths of the two methods are discussed and synergies are identified. The methods are shown to be complementary. When applied together as an integrated framework, they provide a system architect descriptive and evaluative capability unavailable from either methodology alone. The descriptive capabilities and definitional framework of Object-Process Methodology is used to improve formulation of Functional Requirements and Design Parameters in Axiomatic Design. Examples demonstrate that adequate descriptions of both function and architecture require a combination of objects and processes. Object- Process Methodology templates for describing function and architecture using such combinations are presented. Adherence to Axiomatic Design's Independence Axiom is evaluated through patterns identified in Object-Process Diagrams.
