ObjectProcess Methodology OPM Language Principles and Vivid OPM

Object-Process Methodology (OPM): Language Principles and Vivid OPM: Model-Driven System Visualization at the The Enterprise Systems Modeling Laboratory http: //esml. iem. technion. ac. il/ Professor Dov Dori Faculty of Industrial Engineering and Management, Technion Presentation to VISIONAIR Project Nov. 15, 2011

� The Enterprise Systems Modeling Laboratory was founded in 2009 � Designed especially to function as a technology-enabled active learning and research site � Used for research in conceptual modeling and visualizations

The Educational Concept Students work in teams of variable sizes according to the needs and class size. ◦ Each team can, for example, play the role of an enterprise with four main departments, e. g. , marketing, logistics, manufacturing, and support. Teamwork is central in this activity. ◦ It emulates real industrial and commercial environments, where no one is a solo performer and no significant achievement can be the result of the actions of any single individual.

The Physical Infrastructure � The physical infrastructure is inspired by the Technology-Enabled Active Learning (TEAL) project at MIT for undergraduate physics teaching � This infrastructure achieves the goals that are derived from the educational concept. � It constitutes a departure from the traditional frontal teaching mode and lecture hall to the studio approach. � The lab is a 7 by 7 meters room with five clovershaped desks with three computers each around the professor’s station and four viewing screens, one on each wall. � A server connects the 17 computers of the lab so study and research can be done collaboratively. � A High-Definition Video-Conferencing facility enables to hold joint sessions with universities and institutions worldwide.

From Idea to Reality

� � � A powerful server with 17 networked “Chip-PC” workstations Four large screen LCD wall-mounted displays Removable portable and programmable touch-screen control panel IP-Based Video conferencing capabilities Ability to record and transmit long sessions for offline viewing, distance learning and analysis

CRANFIELD UNIVERSITY PROJECT: Conceptual model of a low-cost £ 1000 scanner for use in primary care 2. UNIVERSITY OF SALFOR PROJECT: Framework for Innovation and Research at Media. City. UK (FIRM) Methodologies in Information Systems Development Study in depth principles of the two leading model-based systems engineering languages: Object-Process Methodology and Sys. ML – System Modeling Language. Learn about and take part in ISO standardization and modelbased standards authoring Participate in standardizing OPM as an ISO Standard

Simulated Animation Projects NASA Smackdown Project The SISO Simulation Smackdown is an effort to promote better awareness and understanding of both the importance and the complexity of modern modeling and simulation through hands-on mentoring and participation with modeling and simulation practitioners. TALOS autonomous robot project Develop and field test the innovative concept of a mobile, modular, scalable, autonomous and adaptive system for protecting European borders.

International Standards and Knowledge Generation Projects ISO Standardization of OPM We advocate a model-based systems engineering approach for creating “industry-strength” technical documents Technical document authoring is the function of the system – the organization – that delivers the technical document. Systems Engineering Body of Knowledge (SEBo. K) The SEBo. K is a guide to the body of knowledge, providing references to detailed sources for additional information. The SEBo. K is primarily domain independent, with implementation examples providing the domain-specific context. The SEBo. K is focused on engineered systems: products, services, systems of systems (So. S), and enterprises

Software Development Projects Web OPCAT Project ◦ A Web- and cloud-based IDE and implement the formal operational semantics definitions of OPM. ◦ Our vision is to have a universal repository of standard OPM model snippets in various domains. ◦ They are freely available in the cloud as “Lego” pieces from which anyone can easily build, test, and run OPM models using a friendly cloud environment for their assembly. ◦ Models should be populated with instances and be simulated on the fly.

The two OPM things: Objects and Processes Objects exist. Processes happen to objects. They transform objects: • Processes create objects • Processes consume objects • Processes change objects 13

OPM Entities: Things and States Object: A thing that exists or might exist physically or informatically. ◦ Objects are stateful: Objects can have states State 1 State 2 At each point in time a stateful object is at one of its states - static, or in transition between two states – undergoing change Process: A thing that transforms an object. ◦ Transforming an object is: creating it, consuming it, or changing its state. Processing 14

Compact Ontology: A Minimum Length OPM alphabet OPM unifies the system’s structure and behavior throughout the analysis and design of the system within one frame of reference using a small alphabet: ◦ Two types of things: (1) stateful objects (2) processes ◦ Two families of links: (1) structural links: connect objects with objects (2) procedural links: connect processes with objects 2/1/2022 15

What is in an OPM Model? The OPM model consists of a set of Object-Process Diagrams (OPD set) and a corresponding Object-Process Language (OPL text) – a subset of English OPD: OPL: Purifying changes Copper from raw to pure.

OPM Elements: Entities and Links Entity types: ◦ Object: A thing that exists for some time ◦ State: A situation at which an object can be ◦ Process: A thing that transforms an object Link types: ◦ Structural link: A link denoting a persistent relation between objects ◦ Procedural link: A link between a process and the object it transforms or a state of that object

OPD Example: The TALOS Project

OPM Feature I: Three-Aspect Unification ◦ Function (utility aspect: why is the system designed, what value is it expected to provide? ), ◦ Structure (static aspect: what is the system made of), and ◦ Behavior (dynamic aspect: how the system changes over time) Are expressed in OPM bi-modally in a single model. The model view multiplicity problem is avoided – no mental integration load. 19

OPM Feature II: Bi-modal expression ◦ An OPM model is expressed by two modalities: Intuitive yet formal graphics via a set of interrelated Object-Process Diagrams (OPDs), and An equivalent subset of natural language text (currently English), called Object-Process Language (OPL) that is derived automatically from the user input graphics 20
