Dynamic State Charts: composition and coordination of complex robot behavior and reuse of action plots

INTELLIGENT SERVICE ROBOTICS 2014年第2期7卷 53-65页

作者： Stampfer, Dennis Schlegel, Christian Univ Appl Sci Ulm Dept Comp Sci D-89075 Ulm Germany

Support for separation of roles is decisive towards a successful business ecosystem where various stakeholders with dedicated expertises network and collaborate. However, it depends on means for composition(system of systems, reuse of black boxes). This paper proposes Dynamic State Charts as an extension of state charts for composition and coordination of complex robot behavior which is one of the challenges in service robotics. Their states allow to refine their content by choosing from a set of alternative matching state instances for robust task execution and to manage the complexity of real-world tasks. Dynamic State Charts allow reuse and can be bundled with software components and are provided in a repository (idea of an "robot app store") as a step towards composition and separation of roles as necessary for a business ecosystem in service robotics. The approach is demonstrated in a practical application with a service robot.

A process-oriented modeling approach for graphical development of mobile business apps

Mobile app development is an activity predominantly performed by software developers. Domain experts and future users are merely considered in early development phases as source of requirements or consulted for evaluating the resulting product. In the domain of business apps, many cross-platform programming frameworks exist but approaches also targeted at non-technical users are rare. Existing graphical notations for describing apps either lack the simplicity to be understandable by domain experts or are not expressive enough to support automated processing. The MAML framework is proposed as model-driven approach for describing mobile apps in a platform-agnostic fashion not only for software developers but also for process modelers and domain experts. Data, views, business logic, and user interactions are jointly modeled from a process perspective using a graphical domain-specific language. To aggregate multiple use cases and provide advanced modeling support, an inference mechanism is utilized to deduce a global data model. Through model transformations, native apps are then automatically generated for multiple platforms without manual programming. Our approach is compared to the IFML notation in an observational study, with promising results regarding readability and usability. (C) 2018 Elsevier Ltd. All rights reserved.

Companies have an increasing interest in employing data mining to take advantage of the vast amounts of data their systems store nowadays. This interest confronts two problems: (1) business experts usually lack the skills required to apply data mining techniques, and (2) the specialists who know how to use these techniques are a scarce and valuable asset. To help democratise data mining, we proposed, in a previous work, the development of domain-specific languages (DSLs) that hide the complexity of data mining techniques. The objective of these DSLs is to allow business experts to specify analysis processes by using high-level primitives and terminology from the application domain. These specifications would then be automatically transformed into a low-level, executable form. Although these DSLs might offer a promising solution to the aforementioned problems, their development from scratch requires a considerable effort and, consequently, they are costly. In order to make these languages affordable, we present FLANDM, an ecosystem devised for the rapid development of DSLs for data mining democratisation. FLANDM provides a base infrastructure that can be easily customised for the particularities of each domain, enabling controlled and systematic reuse of previously developed artefacts. By using FLANDM, new DSLs for data mining democratisation can be defined achieving a 50% of reduction in their development costs. (C) 2018 Elsevier Ltd. All rights reserved.

PRECISION AGRICULTURE 2017年第6期18卷 974-996页

Pest control is a major issue in agricultural management due to crop yield losses caused by pests. In this context, integrated pest management aims to suppress pest populations below an action threshold to minimize their impact. This paper presents the development of a web tool based on the Spanish regulations for the integrated pest management of table grapes;this provides decision support for evaluating when a particular pest action threshold has been crossed thus affecting table grape crops. The tool was built using a model-driven software development approach that enables software system generation from the problem's knowledge model. The design of the knowledge bases which contain the system's decision rules is also described. It is divided into knowledge bases that contain general knowledge related to the table grape crop as well as several specific knowledge bases (one per pest) containing the reasoning model that deduces the risk associated with a particular pest. The software has been designed by applying the model-driven development method thus making the system flexible, easy to evolve and adaptable whenever a new pest has to be incorporated into the software.

Over the last two decades, collaborative Systems have become increasingly popular thanks to the many advances made in networks, communications and software tools. Within this field, Collaborative modeling Systems apply the collaborative paradigm to the construction of (often visual) models, where users build diagrams from building blocks and the relationships between them. In these kinds of applications, the work is usually arranged into sessions, with the definition of some kind of time organization between those sessions. This organization is known as a collaboration protocol. Unfortunately, it is not usually easy to define these protocols, and many applications do not allow users to make any use of them. In an effort to overcome these difficulties, in this paper we propose a visual language for defining collaboration protocols for these systems. As such, in our language, sessions, artifacts and the transformations between them can be specified visually, and different coordination relationships (such as fork and join) can be defined. The visual language is included in a development method for collaborative systems that take advantage of the Eclipse platform in order to develop model-driven graphical editors that are enhanced with collaboration capabilities.

Robotic systems are complex, software intensive and heterogeneous composite systems. software systems engineering and system integration is still a major challenge in robotics. We describe how component based software engineering (CBSE), model-driven software development (MDSD) and domain-specific languages (DSLs) for variability management complement each other in addressing the robotics software challenge. We outline how these approaches pave the way towards a software business ecosystem in robotics. We put a focus onto challenges still being considered as open and worth being addressed next.

software modeling is considered as the high-level design technique for describing abstract statements about software systems. While some practitioners create models for the early analysis of their design decisions and generating code from their models, some practitioners create models for the eased communication among sta- keholders. There also exist practitioners who ignore modeling and directly proceed with coding. We aim in this paper to understand the challenges that practitioners face with in their software modeling activities. We sur- veyed 80 practitioners from 18 countries who work in 18 different industries. We focussed on 8 categories of software modeling challenges: (i) managing the language complexity, (ii) extending modeling languages, (iii) domain -specific modeling environments, (iv) developing formal modeling languages, (v) analysing models, (vi) separation of concerns, (vii) transforming models, and (viii) managing models. As the results show, the se- paration of concerns is the least challenging category for practitioners, while analysing models is the top challenging category. Various concrete challenges in different categories have been observed, including (i) using the modeling languages with steep learning -curve, (ii) extending the language semantics without inconsistencies and updating the language tools accordingly, (iii) evolving the DSL tools with new requirements, (iv) defining the languages? formal semantics in terms of the translations in any formal languages, (v) decomposing models into separate viewpoints and analysing the consistencies between different viewpoint models, (vi) the consistent model transformation and the model synchronisations, (vii) using model checkers for formal analysis, and (viii) versioning models.

Groupware systems are usually difficult to design when following traditional methodologies and approaches for single user systems. In this regard, model-driven approaches have been gaining attention in recent years. In accordance with this paradigm, we developed the SpacEclipse method in a previous work, which is a method for developing collaborative modeling groupware based on the plug-ins in the Eclipse modeling Project. However, this method presents some deficiencies that we have tried to overcome in this work. In order to achieve this goal, we have chosen the CIAM methodology, which allows the modeling of collaboration, users, tasks, sessions and interactive issues and which is also supported by Eclipse-based tools. In this paper, we explain how the integration of CIAM elements in the SpacEclipse method has been carried out and resulted in a new method with its own methodological, conceptual and technological frameworks. To prove the validity of the method, we have applied it to a re-engineering process in the development of an existing tool. (C) 2013 Elsevier Ltd. All rights reserved.

TextX is a meta-language and a tool for building Domain-Specific Languages in Python. It's built on top of the Arpeggio PEG parser and takes away the burden of converting parse trees to abstract representations from language designers. From a single grammar description, textX constructs Arpeggio parser and a meta-model in run-time. The meta-model contains all the information about the language and a set of Python classes inferred from grammar rules. The parser will parse programs/models written in the new language and construct Python object graph a.k.a. the model conforming to the meta-model. The textX tool has support for error reporting, debugging, and meta-model and model visualization. It is used in industrial environments and teaching Domain-Specific Languages course at the Faculty of Technical Sciences in Novi Sad. It is a free and open-source software available at GitHub under the MIT license. (C) 2016 Elsevier B.V. All rights reserved.

Towards a Formal Specification of Production Processes Suitable for Automatic Execution

OPEN COMPUTER SCIENCE 2021年第1期11卷 161-179页

Technological advances and increasing customer need for highly customized products have triggered a fourth industrial revolution. A digital revolution in the manufacturing industry is enforced by introducing smart devices and knowledge bases to form intelligent manufacturing information systems. One of the goals of the digital revolution is to allow flexibility of smart factories by automating shop floor changes based on the changes in input production processes and ordered products. In order to make this possible, a formal language to describe production processes is needed, together with a code generator for its models and an engine to execute the code on smart devices. Existing process modeling languages are not usually tailored to model production processes, especially if models are needed for automatic code generation. In this paper we propose a research on Industry 4.0 manufacturing using a Domain-Specific modeling Language (DSML) within a model-driven software development (MDSD) approach to model production processes. The models would be used to generate instructions to smart devices and human workers, and gather a feedback from them during the process execution. A pilot comparative analysis of three modeling languages that are commonly used for process modeling is given with the goal of identifying supported modeling concepts, good practices and usage patterns.
