“…The model-based object oriented systems engineering (MOOSE) approach [10] uses a homogeneous modelling notation in an integrated approach for the engineering of computer systems. The intention is to provide full lifecycle support from initial product specification through to implementation.…”

“…MOOSE draws upon many of the ideas embodied in the graphical approaches to software development to produce an approach to embedded computer system development. The reasons for the 'object-oriented' nature of the models will not be developed here, except to comment that this kind of structure produces designs with greater stability and safer encapsulation of detail than process centred approaches, and it lends itself well to the provision of library modules (objects) that facilitate the reuse of both designs and implementations [10]. The 'model-based' aspect of the approach is more relevant to this paper.…”

“…A MOOSE model consists of a hierarchy of diagrams called Object Interaction Diagrams (OIDs) [10]. They collectively represent the operation of a system as an interacting set of objects, in which each object has responsibility for a specialized and cohesive share of the system's total functionality.…”

This paper discusses the validation, by simulation, of Behavioural Models of computer systems that are developed as part of a whole lifecycle approach to product development (model-based object oriented systems engineering (MOOSE)). The paper summarizes the MOOSE approach and introduces its notation for defining Behavioural Models, which are logical models of a system, uncommitted to hardware or software implementation. In the MOOSE approach, a Behavioural Model is transformed into a Committed Model of the system that identifies the hardware and software components that make up the system's implementation. This paper concentrates on the dynamics of these models, viewed both as paper models and as executing simulations. It considers the validation techniques that can be employed for both types of model and discusses the design of the software necessary to support the executable simulations. The paper is illustrated by an example model of a video controller system.

A n extended example of the application of a new method for the Object Oriented codesign of embedded .systems (MOOSE) is presented. The example concerns an intelligent video system which is currently being developed using MOOSE. The paper highlights the notable features of the method (including executablity and the commitment process) with reference to the design of the video system, and presents tentative conclusions regarding the method's suitablity for embedded system codesign.

Background. This is part of an ongoing set of studies to develop a framework and techniques for rich semantic modeling, based on traditional ontologies and upper ontologies. Such models should provide the basis for direct representation of complex texts such as scientific research reports and descriptions of historical events. Semantic models have been developed to describe mechanisms and explore how semantic models can be related to object-oriented programming languages.Objective. Object-oriented semantic modeling was applied to two simulations: of a waterfall and of the cardiopulmonary system. Issues related to the components of these models and their interaction were examined. Results. Complete executable models for the waterfall and the cardiopulmonary system examples are demonstrated. Specific recommendations are offered for handling States, Portions of Matter, Meta-Operators, and Systems.
