This tutorial presents object-oriented mathematical modelling, a fast-growing area of modelling and simulation that provides a structured, computer-supported way of doing modular, mathematical and equation-based modelling of Cyber-Physical Systems (CPS). Modelica effectively unifies and generalizes object-oriented with mathematical modelling concepts in a single language. The first part of this tutorial gives insight into the rationale behind and examples of equation-based modelling. Object-oriented mathematical modelling languages are positioned at one level in a stack of languages ranging from domain-specific languages (such as SimMechanics), over generic physics-aware modelling languages (such as Bond Graphs) and equation-based modelling languages (such as Modelica and Simscape), to computationally causal languages (such as Simulink), to discretized code for numerical simulation complying to the Functional Mockup Interface (FMI) standard. Each of these levels are introduced with a particular focus on the equation-based modelling level. A basic introduction to simulation concepts and techniques is also given.
Hans Vangheluwe is a Professor at the University of Antwerp in Belgium, and an Adjunt Professor at McGill University in Montréal, Canada. He was one of the founding members of the Modelica Design Team in the mid '90s. He works on modelling language engineering foundations and tool implementations.

This tutorial presents object-oriented mathematical modelling, a fast-growing area of modelling and simulation that provides a structured, computer-supported way of doing modular, mathematical and equation-based modelling of Cyber-Physical Systems (CPS). Modelica effectively unifies and generalizes object-oriented with mathematical modelling concepts in a single language.
The second part of this tutorial builds on the first part and goes "under the hood" of the Modelica language, In particular, the semantics of a Modelica model is explained in terms of flattening the inheritance and coupling structure, of causality assignment, and of algebraic loop detection and sorting. Various extensions to basic continuous-time modelling such as hybrid and dynamic structure modelling are further introduced.

Presenter: Michel R.V. Chaudron, Chalmers & Gothenburg University
Modelling is applied in many different ways in software engineering: for facilitating communication, for analysing systems, for generating code and tests. Thus, the evaluation of modelling techniques, languages and tools is needed in order to assess their advantages and disadvantages such as their applicability in different contexts, their ease of use, and other issues such as skills needed and costs incurred. Many papers submitted to the MODELS conference lack empirical validations of their proposed methods/techniques. This tutorial offers an introduction to empirical methods in software engineering and thereby aims to equip researchers in the MODELS community with knowledge needed to perform pragmatic evaluations. This tutorial is offered by person(s) with broad experience in several types of empirical studies. The tutorial will offer participants the opportunity to discuss how to design empirical studies (focus is expected on experiments, surveys, and case studies) for their own research question.
Michel R.V. Chaudron is currently full professor and head of the Software Engineering Division at the joint department of Computer Science and Engineering of Chalmers and Gothenborg University in Sweden. Prior to that, he worked at Leiden University and TU Eindhoven in The Netherlands and as IT-consultant with CMG (now CGI).

He has published more than 100 papers in these areas. He has been active member of several conferences in these areas including CBSE, MODELS, Euromicro-SEAA, ESEM.
Presenter: Zinovy Diskin, University of Waterloo; Co-author Tom Maibaum, McMaster University
There is a hidden intrigue in the title. Category theory (CT) is one of the most abstract mathematical disciplines, jokingly nicknamed "abstract nonsense". MDE is a recent trend in software development, industrially supported by standards and tools, and enjoying the status of a new "silver bullet". Surprisingly, categorical patterns are directly applicable to mathematical modeling of structures appearing in everyday MDE practice. Model merging, transformation, synchronization, and other important model management (MMt) scenarios can be seen as executions of categorical specifications.
However, the appearance of CT in MMt is not accidental. We’ll show that mappings are fundamental for MMt and actually define the nature of the discipline. A typical MMt operation takes a configuration (diagram) of models and mappings as its input, and outputs another configuration. Specifying such operations in precise terms needs a special diagrammatic rather than usual tuple-based algebra. Reasoning about such operations needs a special diagrammatic rather than ordinary formula-based logic. The mathematics of diagrammatic algebra and logic is CT, hence, the tutorial. We’ll consider three small but carefully designed examples of MMt operations. By analyzing them, we show basic principles of categorical thinking without delving into formalities, and demonstrate several patterns of structural design suggested by CT. These patterns, together with guidance for their usage, is what we assume attendees will take home from the tutorial.

Presenter: Jon Whittle, Lancaster University
This tutorial will discuss how MDE is used in
practice in industry. The tutorial will present: (i) a number of
success and failure factors affecting adoption of MDE in practice;
(ii) case studies of how companies have successfully used MDE in
practice; and (iii) technical, social and organizational factors that
affect how successful MDE tools are applied in practice. The
tutorial is grounded in evidence collected over a period of three
years from over twenty companies that use MDE. Finally, the
tutorial will reflect on what these findings mean to researchers,
practitioners and students working on MDE. The tutorial is targeted towards both researchers and practitioners. Researchers will learn how MDE is actually applied in practice, which will inform their research questions. Practitioners will learn how other companies have been successful with MDE and will be able to transfer those practices to their own situation.

Model Driven Engineering (MDE) brings together multiple technologies and critical innovations and formalizes them into the next wave of software development methods. This tutorial will cover the basic patterns, principles and practices of MDE. The three main MDE categories include the development of Domain Specific Languages (DSL), Domain Specific Editors (and Views), and Domain Specific Transformation Engines or Generators. Expressed in terms of language development technology, these mirror the development of the Abstract Syntax, Concrete Syntax and Semantics of a new Domain Specific Language. This tutorial will cover the basic effective patterns, principles and practices for developing these MDE software artifacts. The tutorial will show how to apply these concepts as effective means with which to both raise levels of abstraction and domain specificity and thus increase power and value of tools and languages that allow developers to tackle the complexities of today’s software systems. It will also show how to effectively leverage abstraction without sacrificing the ability to robustly and precisely refine these abstractions to solve complex real world problems. To show these patterns and principles in action, this tutorial will cover the details of how to leverage MDE Language Workbenches and frameworks in support of robust software development.
Bruce Trask has been developing real world complex Distributed Real-Time Embedded systems for over 27 years specializing in MDE as applied to these systems in the last 12 years.

The Architecture Analysis and Design Language (AADL) is an SAE International
Standard dedicated to the precise modeling of complex real-time embedded
systems, covering both hardware and software concerns. Its definition relies on
a precise set of concepts inherited from industry and academics best practice:
clear separation of concerns among layers, rich set of properties to document
system metrics and support for many kind of analysis: scheduling, safety and
reliability, performance, but also code generation. In this tutorial, we provide
an overview of AADLv2 and illustrate how several analyses can be combined on an
illustrative example: an ADIRU system. In this tutorial, we focus on safety
analyses and also demonstrate the use of AADL to both verify and implement
automatically a real-time embedded systems.

Presenter: Bran Selić, Malina Software Corp [Slides of his tutorial]
Cyber-physical systems (CPS) are complex engineering systems that interact directly with the physical world. They generally combine a mixture of different engineering technologies, (e.g., mechanical, electrical, hydraulic) with embedded software. In these systems the software is responsible for monitoring and control functions. Traditional design approaches for such systems were based on an early decomposition into technology-centric subsystems followed by an integration step near the end of the development cycle. In contrast, modern CPS design takes a more holistic approach, treating the system as an integral whole, allowing for increased flexibility in allocating functional responsibilities to the most appropriate technologies. This is primarily achieved through the more extensive and more effective use of computer-based engineering models throughout design. A key technical challenge in this process is how to construct and analyze practical models of such systems, given that each of the technologies involved may require its own idiosyncratic modeling discipline. In the past decade, a new generation of computer-based modeling languages has emerged with a view to addressing this problem. In this tutorial, we consider two industry standard modeling languages from this category, SysML and MARTE. We explore the rationale behind them (the tutorial presenter was an active and leading contributor to both standards), the relationships between them, and how they can be combined for effective and agile CPS design. All methods and patterns described are illustrated using practical examples.

A Cyber Physical Systems (CPS) typically relies on a highly heterogeneous interconnection of platforms and devices offering a diversity of complementary capabilities: from cloud server with their virtually unlimited resources to tiny microcontrollers supporting the connection to the physical world. This tutorial presents a tool supported Model-Driven Software Engineering (MDSE) approach targeting the heterogeneity and distribution challenges associated with the development of CPS. The approach is based on a domain specific modelling languages called ThingML. The foundations and rational of ThingML have been elaborated over the past years based on a set of experiences and projects aiming applying the state of the art in MDSE in practical contexts and with different industry partners. The aim of the tutorial is (i) to reflect on these experiences to motivate the approach and its implementation, (ii) to describe the approach and its usage by the actors involved in the development of CPS and (iii) to provide hands-on experience with the associated tools. In addition to a set of hands-on exercises, the tutorial will end with a "mini-hackathon". The attendees will be given a couple of days to submit a solution to a challenge and a price will be awarded to the best contribution.

Presenters: Miguel Garzon, University of Ottawa and Andrew Forward, CENX Corp
In this tutorial we will teach participants how to rapidly develop applications starting with models, and how to reverse engineer code into models
using the Umple open-source technology. Umple embeds modeling constructs such as UML class diagrams and state diagrams, aspects, patterns, traits, mixins
plus many other features, into code written in Java, C++, PHP or a mixture. It also allows the inverse. i.e. adding code to textually-rendered models. Model
diagrams can either be edited (with the textual syntax being dynamically updated) or else generated from the textual syntax. Umple has state-of-the art
code generation for the languages mentioned above, and several others. Umple also performs extensive analysis of models and generates many additional
outputs such as state tables. Umple is written in itself.
Miguel Garzon is a PhD student and Part Time Professor at the University of Ottawa. He expects to graduate by the time of this tutorial. He has been one of the lead developers of Umple for the last four years, focusing on technology for reverse-engineering systems into Umple (umplification). He has used Umple in teaching contexts at the high-school and undergraduate levels.
Andrew Forward is one of the Umple project founders, having worked on it since its inception in 2007. He is currently is a software engineer working in industry, where he employs many technologies, including Umple. He received his PhD in 2010 from the University of Ottawa and has continued to conduct research in modeling. He regularly coaches undergraduate from across Canada and the US who are using Umple in their fourth-year software engineering projects.
These are 90-minute sessions included in the price of the main conference registration; they will be held in parallel with paper sessions.

Use case modeling, including use case diagrams and use case specifications, is commonly applied to structure and document requirements. Use case specifications are usually structured, unrestricted textual documents complying with a certain use case template. However, because use case models remain essentially textual, ambiguity is inevitably introduced. We present in this tutorial a use case modeling approach, called Restricted Use Case Modeling (RUCM), which is composed of a set of well-defined restriction rules and a modified use case template. The goal is two-fold: (1) restrict the way users can document use case specifications in order to reduce ambiguity and (2) facilitate the (automated) requirements analysis and generation of downstream artifacts such as UML models.
In the last few years, based on RUCM, we proposed the Zen-RUCM framework (implemented as a platform, http://zen-tools.com/Zen-RUCM.html), to cover various aspects of natural language based specification/modeling/analysis of requirements and generation of UML models and test cases. A series of methodologies (with tool support) were therefore proposed, developed and evaluated with industrial case studies, including requirements modeling for real-time systems (RUCM4RT), test case specifications (RTCM) and automatically test case generation. In this tutorial, we will present the Zen-RUCM framework, the RUCM, RUCM4RT and RTCM methodologies, along with tool demonstration on real-world case studies.
