Function Modeling for Collaborative Embedded Systems

Abstract

The evolution from traditional embedded systems to dynamically interacting, collaborative embedded systems increases the complexity and the number of requirements involved in the model-based development process. In this chapter, we present the new aspects that need to be considered when modeling functions for collaborative embedded systems and collaborative system groups, such as the relationship between functions of a single system and functions resulting from the interplay of multiple systems. These different aspects are represented by a formal, domain-independent metamodel. To aid understanding, we also apply the metamodel to two different use cases.

“…In our experience, the complexity of the development, operation and maintenance of process-control software is not so much associated with classic control functions, i.e. achieving and maintaining the desired state of process variables (hereinafter referred to as basic control), but more with the software im-plementing the discrete behavioural control [2], which performs a sequence of activities that ensure that the goals of the system or process are achieved [3] (hereinafter referred to as procedural control). In addition to greater complexity, procedural control is also characterized by a significantly higher degree of variability between the individual applications than is the case in basic control.…”
