Using the CIF 3 toolset, we illustrate the general idea of controller synthesis for product line engineering for a prototypical example of a family of coffee machines. The challenge is to integrate a number of given components into a family of products such that the resulting behaviour is guaranteed to respect an attributed feature model as well as additional behavioural requirements. The propo...

In this paper we present an approach for QoS management that can be applied to a general class of real-time distributed computation systems. In the proposed approach a switching hybrid system model is used to represent the system. In this setting, the QoS specifications are transformed into set-point specifications and a limited-horizon online supervisory controller is used to move the system t...

This paper expands upon results of previous research dealing with the supervisory control of Petri net modeled discrete event systems that contain uncontrollable transitions. The concept of unobservable plant transitions is introduced here and incorporated into the controller design procedure. New conditions are developed which govern the existence of controllers for these problems. Two procedu...

A supervisor is generated with Supervisory Control Theory [3], resulting in a nonblocking and minimally restrictive controller. Time is introduced time using timed automata theory. A compact data structure is used to keep track of the time information in the timed automata: Heaps of Pieces [2]. The fastest sequence of events is found, using graph search algorithms of Dijkstra and A [1]. This is...
