    Estudio, implementación y evaluación de la arquitectura para una herramienta de integración continua de investigaciones en ingeniería de líneas de productos de software

    On repeated occasions, companies are faced with making decisions regarding what type of technology to use or how to redesign their technologicalbase. In some cases, these decisions are taken in an accelerated manner with the sole aim of generating optimal and competitive response times in the market with functional products that satisfy specific market needs and which, in turn, without seeking to do so, incorporate a zero vision of extensibility, growth, opportunity for improvement and a large number of quality attributes that provide high quality to their products, thus generating high rates of technical debt, coupling between components and rates of improvement, incorporate a null vision of extensibility, growth, opportunity for improvement and a large number of quality attributes that provide high quality to their products, thus generating high rates of technical debt, coupling between components and null rates of reusability causing a greater effort to maintain, extend or even think about rebuilding their software capabilities in the near future. In this work, we propose and evaluate the architecture of a Web application capable of enabling the modelling and simulation of systems (software and cyber-physical at various levels of abstraction) within the framework of a research software called VariaMos. The context of VariaMos, being a software of continuous integration of research results in an engineering framework, is characterized by a constant growth of modelling languages and reasoning mechanisms on the systems or families of systems to be created and simulated with the web application associated with the software (VariaMos). Therefore, the architecture of this web application must incorporate adequate standards for its correct maintainability, extensibility, and growth through the integration of the new proposals of the VariaMos work team. To achieve this, the master project reported in this manuscript followed the following process: First, we identified the most relevant quality attributes following the recommendations presented in the standard (ISO/IEC 25000). Subsequently, we built the solution framework to derive the candidate architecture for VariaMos, and we will detail the construction of the required architecture in several layers. The third step consists of familiarizing the proposal to the VariaMos team and a retrospective review of the benefits of this new proposal with respect to the previous version of the VariaMos tool. In the fourth step, we implement the improved version of the architecture and proceed to perform a usability evaluation of the resulting web application. The evaluation aims to answer the following research question: What are the architectural features of an engineering modelling and simulation platform that can be extended without having to redefine the platform architecture as engineering languages or reasoning mechanisms grow, and to what extent can they be applied in a collaborative Web application? These results constitute a preliminary empirical proof of the benefits that this new architecture has brought in favour of the strategic and technical objectives of the new VariaMos and give us a series of recommendations that allow us to further improve the tool. Finally, we consider the results of the evaluation to improve the web application that will serve as a working platform for the VariaMos working group in the coming years and document the new result in this manuscript.

    Rediseño del proceso de mantenimiento para los activos productivos de la planta de superficies

    Currently, and in the face of high competition from the world market, modern companies are obliged to identify, propose and achieve optimization at all their organizational levels, since no productive sector escapes this trend. Research and development (R&D) and continuous improvement seek to make operations more efficient and effective, which is why they have become a basic component of management in most companies. Companies must implement methodologies to determine the current status of processes through an introspection (internal review) or an external analysis with other companies in the sector or with respect to a standard, through the analysis of variables that can generate cost overruns, reprocesses, inefficiencies, weaknesses, etc., that is, with the application of a benchmarking methodology; the this form determines the gaps and opportunities for improvement that it has and that could be implemented. At present, the maintenance management of productive assets demands great importance to achieve the objectives and goals of productive companies, in order to add value to achieve the greatest possible operational availability in a way that allows obtaining an appropriate cost of In accordance with organizational guidelines and make it possible to be competitive in the industry. Over the years, maintenance has evolved in a very significant way due to the fact that currently there are multiple methodologies, techniques and concepts for its application, with which it is possible to adequately optimize human, technical and material resources and also increase the availability of the productive assets of companies. The implementation of tools and models for maintenance management, such as total productive maintenance (TPM), maintenance focused on reliability (RCM), optimization of planned maintenance (PMO) and world-class maintenance, among others, applied to the productive assets of tiles or surfaces, is a suitable option to be able to reinforce and meet the company's objectives in order to increase the availability, reliability and maintainability of its production processes, while optimizing the programming and execution of plans current maintenance. For this, the maintenance strategy must be reinforced and restructured with the identified improvement opportunities, which could be presented in the future to the operations management so that it determines priority, times, objectives and resources to be assigned for its implementation.
