For example, the State Machines language unit enables modelers to specify discrete event-driven behavior using a variant of the well-known statecharts formalism. Two benefits : easy to learn and use easy to define compliance levels Tian Zhang @ Nanjing University 14 Compliance Levels Level 0 (L0) - This level is formally defined in the UML Infrastructure. Level 1 (L1) - It adds language units for use cases, interactions, structures, actions, and activities. Level 2 (L2) - It adds language units for deployment, state machine modeling, and profiles. Level 3 (L3) - This level represents the complete UML. Tian Zhang @ Nanjing University 15 Diagrams in UML 2.0 与UML1.x相比，UML 2.0将结构元素和行为元素结合 起来建模的能力大大增强； UML 2.0支持13种图(UML 1.x支持9种图)； Class Diagram Activity Diagram Composite Structure Diagram Communication Diagram Component Diagram Interaction Overview Diagram Deployment diagram State Machine Diagram Object Diagram Sequence Diagram Package Diagram Timing Diagram Use Case Diagram Tian Zhang @ Nanjing University 16 Tian Zhang @ Nanjing University 17 Changes from 1.x Add four diagrams; Renamed two diagrams: 原来的协作图(Collaboration Diagrams)改名为通讯图 (Communication Diagrams) ，但语义并没有丰富到与 顺序图等价的地步； 原来的状态图(Statechart Diagrams)改名为状态机图 (State Machine Diagrams)，解决了1.x中状态图和状态 机的语义重叠、模糊不清的问题。 Tian Zhang @ Nanjing University 18 Thirteen diagrams in UML 2.0 Structure Diagram Class Diagram Composite Structure Diagram Component Diagram Deployment diagram Object Diagram Package Diagram Behavior Diagram Activity Diagram Use Case Diagram State Machine Diagram Communication Diagram Sequence Diagram Interaction Overview Diagram Timing Diagram Tian Zhang @ Nanjing University 19 Composite Structure Diagram One of the most significant new features in UML 2 is the ability to hierarchically decompose a class into an internal structure. This allows you to take a complex object and break it down into parts The core constructs of Composite Structures are: Part Connector Port Tian Zhang @ Nanjing University 20 Example 1 – TV (1) Fig. 1. Two ways of showing a TV viewer and its interfaces Tian Zhang @ Nanjing University 21 Example 1 – TV (2) 内部结构表示出一个类 如何在内部分解成两部 分以及哪些部分支持并 需要哪些不同接口。 该图说明了每一个TV 观众包含一个控制部分 和一个发生器部分。 Fig. 2. Internal view of a component (example suggested by Jim Rumbaugh) Tian Zhang @ Nanjing University 22 Example 1 – TV (3) Fig. 3. A component with multiple ports You can add ports to the external structure ports allow you to group the required and provided interfaces to show logical interactions that a component has with the outside world Tian Zhang @ Nanjing University 23 When to Use Composite Structures Compare with Packages packages are a compile-time grouping composite structures show runtime groupings Natural fit for showing components and how they are broken into parts Much of this notation is used in component diagrams (Martin Flower).

INTRODUCTION Communication Diagram (a.k.a. Collaboration Diagram) Communication Diagram provides another way to model a scenario. Essentially is a part of Interaction Diagram (just like Sequence Diagram). Each object is represented by an object icon, and links are used to indicate communication paths on which messages are transmitted. Messages presented in the same way as those in sequence diagram. Formerly known as Collaboration Diagram in UML 1.x specification. Communication Diagram represents a combination of information taken from Use Case, Class and Sequence Diagrams describing both the static structure and dynamic behavior of the system. Comparing and Contrasting: Collaboration and Sequence Both diagrams show the same information: Objects/classes Messages Sequence Conditional Repetition Messages to self Sequence Diagram and Communication Diagram are two views of the same scenario. Collaboration diagrams emphasize who-is-talking-to-who. But the time-ordering of the messages who gets obscured. Sequence diagrams emphasize time-ordering. But the who-is-talking-to-who gets obscured. Use the diagram that you are most comfortable with. Structure and Notation of Communication Diagram Objects are named <an object name>:< its class> .

The Unified Modeling Language Use Case Diagrams Class Diagrams Attributes, Operations and ConstraintsConstraints Generalization and Aggregation Sequence and Collaboration Diagrams State and Activity Diagrams 2004 John Mylopoulos UML -- 1 Conceptual Modeling CSC2507 UML Diagrams I UML was conceived as a language for modeling software. Since this includes requirements, UML supports world modeling (...at least to some extend). I UML offers a variety of diagrammatic notations for modeling static and dynamic aspects of an application.

I Modeling objects in terms of use cases is consistent with Cognitive Science theories which claim that every object has obvious suggestive uses (or affordances) because of its shape or other properties. For example, Glass is for looking through (...or breaking) Cardboard is for writing on... Radio buttons are for pushing or turning… Icons are for clicking… Door handles are for pulling, bars are for pushing… I Use cases offer a notation for building a coarse-grain, first sketch model of an object, or a process. 2004 John Mylopoulos UML -- 3 Conceptual Modeling CSC2507 Use Cases for a Meeting Scheduling System Initiator Participant

Anderson Dissertation submitted to the faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Computer Engineering Sandeep K. Shukla, Chair Lamine Mili Alireza Haghighat Chao Wang Yi Deng April 3, 2015 Blacksburg, Virginia Keywords: AADL, CPS, Model-based code synthesis, correct-by-construction code synthesis, Polychrony, code generators, OSATE, Ocarina Copyright 2015, Matthew E. Anderson APECS: Polychrony based End-to-End Embedded System Design and Code Synthesis Matthew E. Anderson (ABSTRACT) The development of high integrity embedded systems remains an arduous and error-prone task, despite the efforts by researchers in inventing tools and techniques for design automa- tion. Much of the problem arises from the fact that the semantics of the modeling languages for the various tools, are often distinct, and the semantics gaps are often filled manually through the engineer's understanding of one model or an abstraction. This provides an op- portunity for bugs to creep in, other than standardising software engineering errors germane to such complex system engineering. Since embedded systems applications such as avionics, automotive, or industrial automation are safety critical, it is very important to invent tools, and methodologies for safe and reliable system design. Much of the tools, and techniques deal with either the design of embedded platforms (hardware, networking, firmware etc), and software stack separately. The problem of the semantic gap between these two, as well as between models of computation used to capture semantics must be solved in order to design safer embedded systems.

  • Sysml Distilled: a Brief Guide to the Systems Modeling Language
    ptg11539604 Praise for SysML Distilled “In keeping with the outstanding tradition of Addison-Wesley’s techni- cal publications, Lenny Delligatti’s SysML Distilled does not disappoint. Lenny has done a masterful job of capturing the spirit of OMG SysML as a practical, standards-based modeling language to help systems engi- neers address growing system complexity. This book is loaded with matter-of-fact insights, starting with basic MBSE concepts to distin- guishing the subtle differences between use cases and scenarios to illu- mination on namespaces and SysML packages, and even speaks to some of the more esoteric SysML semantics such as token flows.” — Jeff Estefan, Principal Engineer, NASA’s Jet Propulsion Laboratory “The power of a modeling language, such as SysML, is that it facilitates communication not only within systems engineering but across disci- plines and across the development life cycle. Many languages have the ptg11539604 potential to increase communication, but without an effective guide, they can fall short of that objective. In SysML Distilled, Lenny Delligatti combines just the right amount of technology with a common-sense approach to utilizing SysML toward achieving that communication. Having worked in systems and software engineering across many do- mains for the last 30 years, and having taught computer languages, UML, and SysML to many organizations and within the college setting, I find Lenny’s book an invaluable resource. He presents the concepts clearly and provides useful and pragmatic examples to get you off the ground quickly and enables you to be an effective modeler.” — Thomas W. Fargnoli, Lead Member of the Engineering Staff, Lockheed Martin “This book provides an excellent introduction to SysML.

  • What Is Package Diagram? How to Draw Package Diagram?
    Visual Paradigm Tutorial What is Package Diagram? How to Draw Package Diagram? What is Package Diagram? How to Draw Package Diagram? Written Date : July 29, 2014 At the beginning of the project, you only have a limited number of diagrams and everything is simple and beautiful. However, when time flies, more and more diagrams have been created and they start to become unmanageable. As a result, your project becomes hard to navigate and diagrams become difficult to locate when you want to review or make changes. How can we fix it up? We can make use of the Package Diagram to organize your diagrams into different packages. This helps you in categorizing your diagrams according to their natures, making them easier to be navigated and located. The Package Diagram also serves as a catalog for you to jump to the diagram that you want to look at. In this tutorial, we will show you how this can be done. Create Packages for your diagrams First, we need to have our packages ready. To create packages: 1. To create a Package Diagram, select Diagram > New from the toolbar. 2. In the New Diagram window, select Package Diagram and click Next. https://www.visual-paradigm.com/tutorials/packagediagram.jsp Page 1 of 11 Visual Paradigm Tutorial What is Package Diagram?

  • Getting Started with Sysml 3 This Chapter Provides an Introduction to Sysml and Guidance on How to Begin Modeling in Sysml
    CHAPTER Getting Started with SysML 3 This chapter provides an introduction to SysML and guidance on how to begin modeling in SysML. The chapter provides a brief overview of SysML, and then introduces a simplified version of the language we refer to as SysML-Lite, along with a simplified example, and tool tips on how to capture the model in a typical modeling tool. This chapter also introduces a simplified model-based systems engineering (MBSE) method that is consistent with the systems engineering process described in Chapter 1, Section 1.2. The chapter finishes by describing some of the challenges involved in learning SysML and MBSE. 3.1 SYSML PURPOSE AND KEY FEATURES SysML1 is a general-purpose graphical modeling language that supports the analysis, specification, design, verification, and validation of complex systems. These systems may include hardware, soft- ware, data, personnel, procedures, facilities, and other elements of man-made and natural systems. The language is intended to help specify and architect systems and specify their components that can then be designed using other domain-specific languages such as UML for software design and VHDL and three-dimensional geometric modeling for hardware design. SysML is intended to facilitate the application of an MBSE approach to create a cohesive and consistent model of the system that yields the benefits described in Chapter 2, Section 2.1.2. SysML can represent the following aspects of systems, components, and other entities: n Structural composition, interconnection, and classification n Function-based, message-based, and state-based behavior n Constraints on the physical and performance properties n Allocations between behavior, structure, and constraints n Requirements and their relationship to other requirements, design elements, and test cases 3.2 SYSML DIAGRAM OVERVIEW SysML includes nine diagrams as shown in the diagram taxonomy in Figure 3.1.

  • Towards Fixing Sketchy UML Models by Leveraging Textual Notations: Application to Real-Time Embedded Systems
    Towards Fixing Sketchy UML Models by Leveraging Textual Notations: Application to Real-Time Embedded Systems Fr´ed´ericJouault and J´er^ome Delatour PRES Universit´eNantes Angers Le Mans (UNAM) TRAME team, ESEO, Angers, France [email protected] Abstract. During the development of real-time embedded system, the use of UML models as blueprints is a common practice with a focus on un- derstandability rather than comprehensiveness. However, further in the development, these models must be completed in order to achieve the necessary validation and verification activities. They are typically per- formed by using several formal tools. Each tool needs models of the sys- tem at a given abstraction level, which are precise and complete enough wrt. how the tool processes them. If UML is appropriate for capturing multiple concerns, its multiple partial views without a global one in- crease the difficulty of locating inconsistency or incompleteness issues. Therefore, ensuring completeness is time consuming, fastidious, and er- ror prone. We propose an approach based on the use of a UML textual syntax closely aligned to its metamodel: tUML. An initial prototype is described, and examples are given. 1 Introduction Using sketchy models is common during software systems development. Such models (also called contemplative models) are just drawings that cannot be au- tomatically processed (e.g., transformed into code, or verified). In the use of such models as blueprints, the focus is on communication rather than on com- pleteness. The UML language is a good candidate for that kind of practice. It is primarily a graphical notation, and it offers a relatively large set of diagrams for representing various concerns.
