text: Investigates the integration of an interactive constraint solver into an existing
2D real-time animation environment in order to achieve a better observability,
traceability and stability of the individual graphical objects. We present two
approaches for assigning constraints to the objects. The first approach assigns
constraints to the objects when they are created, keeping them stable during their
entire life-time. The second approach dynamically changes constraints before the
computation of each frame. The investigation is based on our practical experience
with the complete visual programming language Pictorial Janus and the parallel
constraint solver Parcon.

text: The main goal of the article is to evaluate the suitability of visual programming
languages, i.e., Pictorial Janus (K. Kahn and V. Saraswat, 1990), for the modeling
of complex systems and their control strategies. These systems can be seen as
networks of communicating objects. Objects select strategies for suitable actions
based on incoming messages. Our field of investigation is in computer integrated
manufacturing considering the example of a car manufacturing cell. This color
sorting assembly buffer (CSAB) schedules jobs in queues. The jobs represent car
bodies scheduled in feeder lines for the enameling. Feeder lines collect raw bodies
to blocks. Blocks are bodies which are to be enameled by the same color. This
organization decreases the cost of expensive change-over-times when changing colors
at the enamelling. Blocks of bodies are dislocated from the queue and enameled
successively. Contradictory system goals, such as minimizing color changes and
preserving the sequence of incoming jobs, have to be regarded by appropriate control
strategies. Due to the complexity of this (NP complete) problem and to real time
requirements for online control there are no optimal strategies on hand. Consequently,
suitable heuristics have to be developed. Often they are designed applying a trial-and-error
method. A modeling framework has to support the rapid prototyping of these systems
as well as an expressive end user oriented representation. Both are essential
requirements since end users need other visualization techniques than experienced
designers due to their different knowledge and interests.
