This paper used the Systems Modeling Language (SysML) to explore its applicability and effectiveness to a simple hardware system. The system and design requirements derived from the customer requirements were modeled in the requirements hierarchy diagram. The spring load equation with all the variables and constant were defined in the parametric constraint definition diagram. Parametric constraint on a block diagram was then used to design a conical helical spring. A link between design and requirements was demonstrated in the model. State machine diagrams depicted the finite state‐transition on how a person emptied the mousetrap and how a mouse entered the trap. These diagrams were linked to verification requirements for system verification. SysML is shown to be an effective modeling language for hardware systems. The applicability of SysML to a combined hardware and software system has still to be demonstrated and proven.

The application of Object‐Oriented Systems Engineering Method (OOSEM) to hardware systems has been controversial since it was initiated. This paper will explore its applicability and its effectiveness relative to traditional systems engineering approach. A simple Mouse Trap hardware system was used for the case study. The System Requirements can be derived from the System Diagram. The Activity Diagram can be used to visualize the workflow scenario. The Sequence Diagram can provide earlier interface identification between subsystems. The Collaboration Diagram shows the functional and physical data between subsystems. The Logical Architecture and allocation can generate logical components and develop the Class Diagram for subsystems. The design of this simple hardware system can be accomplished using the OOSEM. A definitive conclusion cannot be made as to which approach, between the traditional systems engineering and OOSEM, is better in assisting a simple hardware system design.

“…Here, the ontological (abstraction and representation), methodological (construction) and operational (deduction) features of the framework are outlined by way of three small-size examples. Let us consider a simplified case of VIDEO-CAMERA-STRUCTURE as modelled in [9]. The V V framework allows the capture of this domain knowledge fragment using a set of IVVCEFO concept descriptions in the following way.…”

This paper outlines an open framework to share information concepts used in domain knowledge modelling and analysis performed before CBS development.The above framework can support the integration of ECBS information models at the domain level by way of the following characteristics. First, a minimalist ontology is introduced t o capture relevant categories of information concepts (i.e. domain abstractions) used in dagerent information modelling approaches. Second, a formal but analyst-oriented representation is adopted to model knowledge about the distinct categories of information concepts captured in CBS domains. Third, category-dependant rules for the costruction of information concept hierarchies are defined as the basis of automatic deductive services. The above characteristics are compared with the corresponding ones of popular data, process and object modelling approaches.
