    Exemplar driven development of software product lines
    (Elsevier, 2012-12-01) Heradio Gil, Rubén; Fernández Amoros, David José; Torre Cubillo, Luis de la; Abad Cardiel, Ismael
    The benefits of following a product line approach to develop similar software systems are well documented. Nevertheless, some case studies have revealed significant barriers to adopt such approach. In order to minimize the paradigm shift between conventional software engineering and software product line engineering, this paper presents a new development process where the products of a domain are made by analogy to an existing product. Furthermore, this paper discusses the capabilities and limitations of different techniques to implement the analogy relation and proposes a new language to overcome such limitations.

    A scalable approach to exact model and commonality counting for extended feature models.
    (Institute of Electrical and Electronics Engineers (IEEE), 2014-05-29) Fernández Amoros, David José; Heradio Gil, Rubén; Cerrada Somolinos, José Antonio; Cerrada Somolinos, Carlos
    A software product line is an engineering approach to efficient development of software product portfolios. Key to the success of the approach is to identify the common and variable features of the products and the interdependencies between them, which are usually modeled using feature models. Implicitly, such models also include valuable information that can be used by economic models to estimate the payoffs of a product line. Unfortunately, as product lines grow, analyzing large feature models manually becomes impracticable. This paper proposes an algorithm to compute the total number of products that a feature model represents and, for each feature, the number of products that implement it. The inference of both parameters is helpful to describe the standarization/parameterization balance of a product line, detect scope flaws, assess the product line incremental development, and improve the accuracy of economic models. The paper reports experimental evidence that our algorithm has better runtime performance than existing alternative approaches.

    A literature review on feature diagram product counting and its usage in software product line economic models
    (World Scientific Publishing, 2013-10-01) Heradio Gil, Rubén; Fernández Amoros, David José; Cerrada Somolinos, José Antonio; Abad Cardiel, Ismael
    In software product line engineering, feature diagrams are a popular means to represent the similarities and differences within a family of related systems. In addition, feature diagrams implicitly model valuable information that can be used in economic models to estimate the cost savings of a product line. In particular, this paper reviews existing proposals on computing the total number of products modeled with a feature diagram and, given a feature, the number of products that implement it. The paper also reviews the economic information that can be estimated when such numbers are known. Thus, this paper contributes by bringing together previously-disparate streams of work: the automated analysis of feature diagrams and economic models for product lines.

    Supporting commonality-based analysis of software product lines
    (Institution of Engineering and Technology (IET), 2011-03-24) Heradio Gil, Rubén; Fernández Amoros, David José; Cerrada Somolinos, José Antonio; Cerrada Somolinos, Carlos
    Software Product Line (SPL) engineering is a cost effective approach to developing families of similar products. Key to the success of this approach is to correctly scope the domain of the SPL, identifying the common and variable features of the products and the interdependencies between features. In this paper, we show how the commonality of a feature (i.e., the reuse ratio of the feature among the products) can be used to detect scope flaws in the early stages of development. SPL domains are usually modeled by means of feature diagrams following the FODA notation. We extend classical FODA trees with unrestricted cardinalities, and present an algorithm to compute the number of products modeled by a feature diagram and the commonality of the features. Finally, we compare the performance of our algorithm with two other approaches built on top of boolean logic SAT-solver technology such as cachet and relsat.

    A SCADA oriented middleware for RFID technology
    (Elsevier, 2012-09-01) Abad Cardiel, Ismael; Heradio Gil, Rubén; Cerrada Somolinos, Carlos; Cerrada Somolinos, José Antonio
    Radio Frequency IDentification (RFID) has emerged as the new technology paradigm for acquisition and information management. RFID can be used to improve significantly the efficiency of business processes by providing the capability of automatic identification and data capture. This technology introduces new challenges on data and process information management in current systems. RFID data are timedependent and dynamically changing. In addition, data carry implicit semantics. The homogeneous data processing of such implicit semantics allows us to propose RFID middleware as a WHO–WHEN–WHERE data problem. This paper presents DEPCAS, a new middleware for RFID information based on the SCADA architecture for control systems. An application of DEPCAS is the resolution of heterogeneous situations, which solves the WHAT or context–aware to apply the auto identification data received from RFID systems in business applications.

    Managing RFID sensors networks with a general purpose RFID middleware
    (MDPI, 2012-06-07) Valero Rodríguez, Enrique; Abad Cardiel, Ismael; Cerrada Somolinos, Carlos; Cerrada Somolinos, José Antonio; Heradio Gil, Rubén
    RFID middleware is anticipated to one of the main research areas in the field of RFID applications in the near future. The Data EPC Acquisition System (DEPCAS) is an original proposal designed by our group to transfer and apply fundamental ideas from System and Data Acquisition (SCADA) systems into the areas of RFID acquisition, processing and distribution systems. In this paper we focus on how to organize and manage generic RFID sensors (edge readers, readers, PLCs, etc…) inside the DEPCAS middleware. We denote by RFID Sensors Networks Management (RSNM) this part of DEPCAS, which is built on top of two new concepts introduced and developed in this work: MARC (Minimum Access Reader Command) and RRTL (RFID Reader Topology Language). MARC is an abstraction layer used to hide heterogeneous devices inside a homogeneous acquisition network. RRTL is a language to define RFID Reader networks and to describe the relationship between them (concentrator, peer to peer, master/submaster).

    A Pragmatic Framework for Assessing Learning Outcomes in Competency-Based Courses
    (Institute of Electrical and Electronics Engineers, 2024-01-19) Vargas, Hector; Heradio Gil, Rubén; Farias, Gonzalo; Lei,,Zhongcheng; Torre Cubillo, Luis de la
    Contribution: A competency assessment framework that enables learning analytics for course monitoring and continuous improvement. Our work fills the gap in systematic methods for competency assessment in higher education. Background: Many institutions are shifting toward competency-based education, thus encouraging their educators to start evaluating their students under this paradigm. Previous research shows that structured assessment models are fundamental in guiding educators toward this adoption. Intended outcomes: An assessment model for competency-based education that is easy to adopt and use, while facilitating the application of learning analytics techniques. Application design: The new framework considerably extends a prior model we proposed three years ago. Two engineering competency-based courses used the framework for assessment. Assessment rubrics were prepared and used for evaluating and collecting the students’ data progressively, thus enabling the use of learning analytics for decision-making. Findings: Thanks to the model, (i) students received a detailed report of their achievements, including a thorough explanation and justification of the evaluation criteria; and (ii) instructors could improve the course and provide objective evidence of their actions to quality assurance agencies. As a result, the framework is presently being used in fifteen courses taught at eight different university degrees at the Pontifical Catholic University of Valparaiso (PUCV).

    Metodología de desarrollo de software basada en el paradigma generativo : realización mediante la transformación de ejemplares
    (Universidad Nacional de Educación a Distancia (España). Escuela Ténica Superior de Ingeniería Informática. Departamento de Ingeniería de Software y Sistemas Informáticos, 2007-03-30) Heradio Gil, Rubén; Cerrada Somolinos, José Antonio; Estívariz López, José Félix
    Muchos autores consideran que el desarrollo de familias de productos, frente al construcción individual de productos aislados, es un paso decisivo hacia la realización sistemática de software y la obtención de economía de alcance. Esta tesis se adscribe a esta corriente y propone un nuevo proceso de desarrollo de familias de productos, denominados EDD (Exemplar Driven Development), que aprovecha la similitud entre los productos de una familia para construirlos por analogía. La primera actividad de EDD es la realización de un producto concreto de una familia. A continuación, se busca cómo flexibilizar este ejemplar para que satisfaga los requisitos del resto de los productos. Es decir, se trata de definir formalmente una relación de analogía que permita derivar del ejemplar los demás productos de forma automática. Por último, se obtienen los productos de la familia parametrizando la flexibilización del ejemplar. Entre las aportaciones de EDD, cabe destacar: * Abordar el desarrollo y el mantenimiento de una familia de productos mediante una estrategia sistemática e interactiva. Lo primero que se construye es un ejemplar que satisface los requisitos fijos de la familia. Después, se incorporan progresivamente cepas de flexibilización que implementa los requisitos variables. * Los requisitos fijos de una familia de productos suelen ser más estables que los requisitos variables. EDD separa la implementación de los requisitos fijos (el ejemplar) de la implementación de los requisitos variables (los módulos que flexibilizan el ejemplar). * La decisión de elaborar una familia a menudo se toma al detectar trabajo repetitivo en el desarrollo aislado de varios productos de un dominio o al identificar oportunidades de negocio en la ampliación de las prestaciones de un producto de éxito. EDD reconoce esta situación y trata de aprovecharla mediante la reutilización íntegra de un ejemplar. La tesis explora distintas maneras.

    Customized Online Laboratory Experiments: A General Tool and Its Application to the Furuta Inverted Pendulum [Focus on Education]
    (Institute of Electrical and Electronics Engineers (IEEE), 2019-09-17) Galán Vicente, Daniel; Chaos García, Dictino; Torre Cubillo, Luis de la; Aranda Escolástico, Ernesto; Heradio Gil, Rubén
    Because of online laboratories (labs), students can perform experimental activities from their mobile devices and/or computers. This article proposes an experimentation environment (EE) that extends the capabilities of interactive online labs with scripting language support. Thus, control engineering students can specify complex experiments, avoid routine tasks, and empirically test controllers they made themselves.

    A Monte Carlo tree search conceptual framework for feature model analyses
    (Elsevier, 2023-01) Horcas, José Miguel; Galindo, José A.; Benavides, David; Heradio Gil, Rubén; Fernández Amoros, David José
    Challenging domains of the future such as Smart Cities, Cloud Computing, or Industry 4.0 expose highly variable systems with colossal configuration spaces. The automated analysis of those systems’ variability has often relied on SAT solving and constraint programming. However, many of the analyses have to deal with the uncertainty introduced by the fact that undertaking an exhaustive exploration of the whole configuration space is usually intractable. In addition, not all analyses need to deal with the configuration space of the feature models, but with different search spaces where analyses are performed over the structure of the feature models, the constraints, or the implementation artifacts, instead of configurations. This paper proposes a conceptual framework that tackles various of those analyses using Monte Carlo tree search methods, which have proven to succeed in vast search spaces (e.g., game theory, scheduling tasks, security, program synthesis, etc.). Our general framework is formally described, and its flexibility to cope with a diversity of analysis problems is discussed. We provide a Python implementation of the framework that shows the feasibility of our proposal, identifying up to 11 lessons learned, and open challenges about the usage of the Monte Carlo methods in the software product line context. With this contribution, we envision that different problems can be addressed using Monte Carlo simulations and that our framework can be used to advance the state-of-the-art one step forward.
