  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.

  text: We investigate a translation of SDL diagrams into the complete visual representation
    of Pictorial Janus (PJ) programs in order to analyze the specification by visual
    debugging and animation. We additionally introduce timing concepts to PJ (Timed
    PJ) for a mapping of the SDL timing statements. The concepts transforming SDL
    interaction and process diagrams into Timed PJ are outlined by an example sketching
    the transformation of an Ethernet CSMA/CD protocol specification.

  text: This article discusses the application of Pictorial Janus (PJ) for the rapid
    development and analysis of protocols by animation and complete visualization.
    In order to make PJ applicable in the context of hardware description we first
    extend PJ by timing facilities (Timed PJ) and introduce an approach for integrating
    VHDL models into this visual framework preserving the simulation semantics of
    VHDL. We finally give the example of the specification and animation of a non
    interlocked protocol.
