History of integration in engineering activities Conventional engineering inherently integrated Our course program Multidisciplinary modeling of product system for lifecycle Virtual space Separated areas (CAD, CAM, CAE, CAT, Etc.) Increasingly integrated concurrent engineering László Horváth UÓ-JNFI-IAM http://users.nik.uni-obuda.hu/lhorvath/
From physical representations to RFLP structure Modification of affected features by contextual connections Integrated Product Information Model (IPIM). The ISO 10303 Integration of CAD, CAE, CAM, etc. in an object model. Feature driven product definition Lifecycle management of product information Product feature generation using embedded knowledge Requirements (R) functional (F), logical (L) and physical (P) structure from SE for multidisciplinary system model Knowledge driven definition of generic model Product definition in RFLP structure Modeling process and simulation structure in model Research in industrial modeling system: demand by changed products V6 technology: Fundamental, applied, commercial research. László Horváth UÓ-JNFI-IAM http://users.nik.uni-obuda.hu/lhorvath/
From physical representations to RFLP and PPR structures Requirements against product. Functional model for requirements. Logical model for functions. Physical level model. Process model for manufacturing Manufacturing system model Model of manufacturing resources László Horváth UÓ-JNFI-IAM http://users.nik.uni-obuda.hu/lhorvath/
Communication with modeling procedures Viewport Provides sight into the model space. Serves communication with model generation procedures. No drawing, no editing, this is definition by control of model generation procedures. Shape model Mathematical representation constructed by control of mathematical procedures. It includes a set of contextual surface represenattion in topological structure. László Horváth UÓ-JNFI-IAM http://users.nik.uni-obuda.hu/lhorvath/
Object modeling of contextual features General information schema Model information schema Object Class (in taxonomy) Paramaters Relationships (contexts) Procedures Feature Properties Type with parameters Representation. In case of shape feature, topology structured geometry. Contextual chain for propagation of parameter changes. Contextual connection Parameter Parameter Feature driven model: feature acts on previously defined features though contextual connections of its parameters. Model must be contextually consistent. Real-time monitoring and simulation prevent the creation of erroneous results. László Horváth UÓ-JNFI-IAM http://users.nik.uni-obuda.hu/lhorvath/
Object modeling of contextual features Theories and methods which are understood in the course of definition of model and experiments using active model. Cartesian coordinate system and transformations. Relating model space and plane in it. Definition of shape using dynamic navigator. Object and its parameters. Feature, its attributes and parameters. Context and contextual chain. Active and passive parameter. Constraint as context. Offset of a surface. Boundary representation at model definition. Function of the space pilot device at the definition of model. László Horváth UÓ-JNFI-IAM http://users.nik.uni-obuda.hu/lhorvath/
Object modeling of contextual features Work in a preselected plane. Dynamic navigator recorded so many important constraints László Horváth UÓ-JNFI-IAM http://users.nik.uni-obuda.hu/lhorvath/

Object modeling of contextual features Constraint active László Horváth UÓ-JNFI-IAM http://users.nik.uni-obuda.hu/lhorvath/
Object modeling of contextual features Shape change is possible but real time simulation reject this modification. Constraint inactive (changed parameter value) László Horváth UÓ-JNFI-IAM http://users.nik.uni-obuda.hu/lhorvath/
Object modeling of contextual features Parameter „activity” changed back to true. The active constraint enforced the original shape using contextual chain. László Horváth UÓ-JNFI-IAM http://users.nik.uni-obuda.hu/lhorvath/
László Horváth UÓ-JNFI-IAM http://users.nik.uni-obuda.hu/lhorvath/ Work in laboratory Only actual task related activities are allowed on workstations. Thematic laboratory tasks are mandatory. Specially composed laboratory tasks do not require special skill in advance because teacher instruct actually. This is a contextual system in which model is active in accordance with modeled contexts. Unwanted contexts active: do not use unnecessary objects and procedures at laboratory work. Course program supposes continuous disciplined work. László Horváth UÓ-JNFI-IAM http://users.nik.uni-obuda.hu/lhorvath/
