Model-Driven Development

With the emergence of Cyber-Physical Systems (CPS), the increasing complexity in development and operation demands for an efficient engineering process. In the recent years DevOps promotes closer continuous integration of system development and its operational deployment perspectives. In this context, the use of Artificial Intelligence (AI) is beneficial to improve the system design and integration activities, however, it is still limited despite its high potential. AIDOaRT is a 3 years long H2020-ECSEL European project involving 32 organizations, grouped in clusters from 7 different countries, focusing on AIaugmented automation supporting modelling, coding, testing, monitoring and continuous development of Cyber-Physical Systems (CPS). The project proposes to apply Model-Driven Engineering (MDE) principles and techniques to provide a framework offering proper AI-enhanced methods and related tooling for building trustable CPSs. The framework is intended to work within the DevOps practices combining software development and information technology (IT) operations. In this regard, the project points at enabling AI for IT operations (AIOps) to automate decision making process and complete system development tasks. This paper presents an overview of the project with the aim to discuss context, objectives and the proposed approach.

Game-construction engines enable developers to reuse assets from previously developed games, thus easing the software-engineering challenges around the video-game development experience and making the implementation of games less expensive, less technologically brittle, and more efficient. However, the construction of game engines is challenging in itself; it involves the specification of well defined architectures and typical gameplay behaviors, flexible enough to enable game designers to implement their vision, while, at the same time, simplifying the implementation through asset and code reuse. In this paper we present a set of lessons learned through the design and construction PhyDSL-2, a game engine for 2D physics-based games. Our experience involves the active use of modern model-driven engineering technologies, to overcome the complexity of the engine design and to systematize its maintenance and evolution.

Abstrakt: Ky punim ka për qëllim të analizoj ndikimin e politikave qeveritare në zhvillimin ekonomik të Kosovës nëpërmjetmbështetjes së NVM-ve. Sistemi i mbështetjes qeveritare është reformuar shpesh, dhe ka një debat të vazhdueshëm në qarqet shkencore dhe qeveritare për mënyrën si duhet të dizajnohet skema e mbështetjes qeveritare për ndërmarrjet e vogla dhe të mesme. Andaj, me të drejt lindin pyetjet: Si i mbështet qeveria e Kosovës NVM-të? A është kjo mënyrë e mbështetjes e përshtatshme për zhvillimin ekonomik të Kosovës? Cilat forma tjera të mbështetjes duhet të aplikohen në Kosovë? Objective i punimit është të i'u përgjigjet këtyre pyetjeve nëpërmejt analizës së të dhënave ekzistuese të mbështetjes e cila aplikohet në Kosovë dhe krahasimin e tyre me vendet e zhvilluara ekonomikisht. Ndërmarrjet e vogëla dhe të mesme janë katalizatori kryesorë i zhvillimit ekonomik në Kosovës, si të tilla politikat qeveritare duhet ti kushtojnë rëndësi të veçant zhvillimit të tyre. Ky studim argumenton atë çka është shumë e nevojshme për politikat e mbështetjes qeveritare në NVM dhe prezanton idenë e zhvillimit të qëndrueshëm të funksionimit të ekonomisë nëpërmjet rritjes së NVM-vë. Fjalët kyçe: Kosovë, politika qeveritare, NVM, mbështetje. Hyrje Një sfidë me të cilin përballën të gjitha vendet në tranzicion është krijimi i një mjedisi miqësorë për NVM-të dhe transformimi i shoqërisë drejt ekonomisë së tregut. Si bëhet ky transformim? Sipas Szabó, A. (2006) thelbi i transformimit politik dhe ekonomik të një vendi në tranzicion është krijimi i sektorit privatë, zhvillimi i sektorit të ndërmarrësi dhe krijimi i ndërmarrjeve të vogla dhe të mesme. Ndërmarrjet e vogla dhe të mesme janë ndër faktorët më të rëndësishëm të rritjes së ekonomisë globale. Në Evropë, NVM-të kanë rolin kryesorë në krijimin e vendeve të reja të punës dhe në rritjen ekonomike prandaj shpesh quhen shtylla kurrizore e ekonomisë Evropiane. Mbështetjae NVM-ve është njëra ndër politikat kryesoree të gjithaqeverivetë shteteve tëBashkimit Evropian (OECD, 2014). Në Bashkimin Evropian (BE), NVM-të përbëjnë 99% të gjitha ndërmarrjeve jofinanciare dhe67% të punësimit total si dhe gjenerojnë 58% të vlerës së shtuar totale (Alexandra Moritz et at, 2015). Sipas (Raportit KOSME, 2014) 419 , në Kosovë ndërmarrjet e vogla dhe të mesme përbëjnë pjesën kryesore të ekonomisë së sektorit privat ku absorbojnë përafërsisht 80% e punësimitdhe 99.9% të ndërmarrjeve në Kosovë. Por pavarësisht rëndësisë së NVM-ve në zhvillimin ekonomik të Kosovës, mjedisi i gjerë i biznesit tregon disa dobësi të cilat e pengojnë këtë sektor që të zhvillohet me potencialin e plotë në aspektin e punësimit, produktivitetit dhe vlerës së shtuar, andaj vlen të theksohet se drejtimi i politikave nga mbështetja e NVM-ve do të thotë drejtim në rritjen ekonomike të vendit. Sipas (Raportit të Ministrisë së Tregtisë dhe Industrisë) 420 në Kosovë një numër i konsiderueshëm i bizneseve fillestare nuk po mbijetojnë dhe zhvillohen në treg si pasoj e së cilës nuk po prodhohet punësim dhe zhvillim ekonomik. Pasi që shumica e shteteve Evropiane dhe botërore i kushtojnë rendësi të veçanetzhvillimit të NVM-ve, atëherë edhe Kosova si shtet me ekonomi të lire të

Software development process has a several challenges for development teams, challenges such as to understand business or client requirements and to provide global solutions covering all the organizational enviroment, keeping down the costs and adding value to the organizations.

With the addition of software in the majority of the organizational process and the necessity for to obtain finished products in less time, the development requirements began to change, for this reason phased development methodology has become obsolete.   

In order to adapt to the rapidly evolving industry, have appeared "SCRUM" which is a methodology for agile application development and "Test Driven Development" (TDD) which is an iterative object-oriented software design practice, which is included into "Extreme Programming” methodology (XP).

In Ecuador there is a large set of companies involved in software development that are using Java platform and JEE architecture for business core construction (BackEnd) into enterprise applications also use JavaScript Framewors implementation in order to optimize the speed of response in client-side presentation layer ( FrontEnd).

This article discusses the use of Test Driven Development (TDD) in conjunction with SCRUM for development of business-oriented Web application that uses AngunlasJS in FrondEnd and Java JEE in BackEnd

Modern model-driven engineering and Agent-Oriented Software Engineering (AOSE) methods are rarely utilized in developing robotic software. In this paper, we show how a Model-Driven AOSE methodology can be used for specifying the behavior of multi-robot teams. Specifically, the Agent Systems Engineering Methodology (ASEME) was used for developing the software that realizes the behavior of a physical robot team competing in the Standard Platform League of the RoboCup competition (the robot soccer world cup). The team consists of four humanoid robots, which play soccer autonomously in real time utilizing the on-board sensing, processing, and actuating capabilities, while communicating and coordinating with each other in order to achieve their common goal of winning the game. Our work focuses on the challenges of coordinating the base functionalities (object recognition, localization, motion skills) within each robot (intra-agent control) and coordinating the activities of the robots towards a desired team behavior (inter-agent control). We discuss the difficulties we faced and present the solutions we gave to a number of practical issues, which, in our view, are inherent in applying any AOSE methodology to robotics. We demonstrate the added value of using an AOSE methodology in the development of robotic systems, as ASEME allowed for a platform-independent team behavior specification, automated a large part of the code generation process, and reduced the total development time.

MegaM@Rt2 project is a collaborative initiative of the ECSEL Joint Undertaking under Horizon 2020 EU programme. The project regroups 26 partners from 6 different European countries who jointly address challenges of engineering modern cyber-physical systems by using model-based engineering methods. Since it is a model-based project, we adopted a similar approach for dealing with requirements analysis, architecture, design, roadmap planning and development status checking. In these tasks, document generation methods were particularly useful to create a set of "live" reference specifications and contractual reports. We believe that these methods perfectly demonstrate relevant benefits of the model-based approach and are applicable to many other contexts. Document generation has several challenges, since the produced documents should address several goals and target different audience. Hence, we describe this approach in detail in this paper in the form of an experience report.

In essence, the MegaM@Rt2 project had a rather trivial task to document inception phase of the project. The challenge arises from the scale of the project, we had to deal with hundreds of requirements from completely different users, hundreds of features of 29 tools, which had to be mapped to those requirements in order to analyze a gap and devise a roadmap for a consistent tool chain. With limited resource on technical coordination we had to be extremely efficient and thus we adopted a model-based approach that we describe in this paper. The paper should be helpful to project managers and architects who wish to discuss on model-based approaches from a practical side.

When dealing with complex systems, information is very often fragmented across many different models expressed within a variety of (modeling) languages. To provide the relevant information in an appropriate way to different kinds of stakeholders, (parts of) such models have to be combined and potentially revamped by focusing on concerns of particular interest for them. Thus, mechanisms to define and compute views over models are highly needed. Several approaches have already been proposed to provide (semi-)automated support for dealing with such model views. This paper provides a detailed overview of the current state-of-the-art in this area. To achieve this, we relied on our own experiences of designing and applying such solutions in order to conduct a literature review on this topic. As a result, we discuss the main capabilities of existing approaches and propose a corresponding research agenda. We notably contribute a feature model describing what we believe to be the most important characteristics of the support for views on models. We expect this work to be helpful to both current and potential future users and developers of model view techniques, as well as to any person generally interested in model-based software and systems engineering.
