The Dynamic System Aspect
Systems change over time. An important motivation in the development of OPM has been to strike a needed balance in a system’s conceptual model between the structural, static and procedural, dynamic aspects of the system. The dynamic aspect of a system specifies how the system operates to attain its function, complementing its static aspect. OPM is at least process-oriented as it is object-oriented. Indeed, OPM models unify structure and behavior in one coherent frame of reference, with time being the fundamental underlying concept. This chapter addresses modeling the dynamics aspect of a system.
