  1. Protocolo: Evaluación de los riesgos del flujo de material en el diseño de instalaciones

    SÁEZ MÁS, AÍDA MARÍA; García Sabater, José Pedro
    [EN] The need of design new layouts or redesign current situation to manufacture new products has increased principally due to changes in customer demand, on both variety aspects and quantity (Lu, Shpitalni, and Gadh, 1999). The complexity increase is also associated with the traffic generated by material handling equipment. This situation can be described as unsafe for workers. Many authors defend that during layout design/redesign a risk analysis is necessary. In contrast others believe that material flow analysis should be a mainly task during this step. Therefore, in this research both considerations have been integrated. So that it is proposed...

  2. Protocol: A literature review about the use of crowdsourcing in educational environments

    Estellés Arolas, Enrique
    [EN] The objective with the protocol described in this paper is to review the existing literature in relation to the implementation of crowdsourcing in educational environments. It seeks to give answer to 4 questions. First, it seeks to answer the question of which kind of crowdsourcing initiatives are more appropriate to be used for educational activities. In second place it’s important to find out whether there is any particular discipline in which crowdsourcing, by its nature, can be applied more naturally. Third, it seeks to identify which factors influence both positively and negatively in the teaching/learning experience using crowdsourcing. Finally,...

  3. Proposal of a Framework for Innovation Competencies Development and Assessment (FINCODA)

    Marín García, Juan Antonio; Andreu Andrés, María Angeles; Atarés Huerta, Lorena María; Aznar Más, Lourdes; García Carbonell, Amparo; González-Ladrón-de-Guevara, Fernando; Montero Fleta, Maria Begoña; Pérez Peñalver, María José; Watts Hooge, Frances Irene
    [EN] In this article we propose a model of innovation competence of people, based on the existing literature to integrate and complement the existing models. The main contribution of this work consists in demonstrating the differences and similarities of current models and in providing a conceptual definition for each model element. In this way, both researchers and people in charge of Human Resources in companies can obtain a framework to design measuring instruments to assess the innovation competence, which can fulfil the twofold demand requirement of validity and reliability.

  4. ¿Cómo se ha evaluado la competencia de innovación en las empresas y las universidades?

    Ramirez Bayarri, Lucia; Marín García, Juan Antonio; Atarés Huerta, Lorena María
    [EN] Companies, in order to increase their competitiveness in a changing environment, demand innovative people. They must be able to measure the innovative competence of individuals. Universities, meanwhile, are training future professionals and have raised the need to strengthen and work the innovation skills of their students, thus promoting access to employment and in turn increasing the competitiveness of both companies and the society. Through this literature review (27 references), innovation competence in the professional field is addressed by studying how companies detect and measure competence of their workers. Moreover, it analyzes how universities work this competence with their students.

  5. Validación de constructos en dirección de operaciones mediante la Teoría de la Medición de Rasch. El caso del constructo “motivación para implantar la mejora continua”

    Sanchez-Ruiz, Lidia; Blanco, Beatriz
    [EN] Construct design and validation is a common practise in the Operations Management field. In this sense, the aim of this study is to present Rasch Measurement Theory (RMT) as richful and useful methodology in order to validate constructs. In order to do so, the measurement controversy in the social science is presented; then, RMT is explained as a solution for this measurement issue; after that, the different applications of RMT are described and, finally, the different stages of the validation process are presented. Thus, this work aims to serve as a guide for those researchers interested in the methodology....

  6. Assembly plant simulation to support decision-making n Layout Design considering safety issues. A case study.

    SÁEZ MÁS, AÍDA MARÍA; García Sabater, José Pedro; Morant Llorca, Joan; Maheut, Julien
    This paper presents a simulation model that has been created to support decision-making during the layout redesign of an engine and transmission assembly plant in the automotive sector. The plant requires a new layout and supply logistic due to an increase in its complexity and daily production. Discrete event simulation has been used to validate an initial proposal and to propose different what-if scenarios of layout and operations management systems. These scenarios will be evaluated regarding materials flow generated throughout the plants. The main focus of the decision process was focused on safety issues related to the material handling. The...

  7. Action planning intervention to identify how to improve selection processes for internships

    Marín García, Juan Antonio; González, Eduardo; Carrasco, Myriam; Ros, Daniel
    In this research into participatory action research, by a team formed by researchers and people in charge in various areas of several multinational companies, we reflected on the advantages and disadvantages of internships and we proposed a procedure for companies to improve the recruitment and selection of industrial engineers, while strengthening relationships between the university and companies, attracting students’ interest, improving their professional competences and providing evidence for their students’ real learning to degree managers at the same time.

  8. Measuring performance at the supply chain level: the role of the chain director

    De Haan, Job A.C.; Sacristán-Díaz, Macarena
    Supply chains lack their own across-the-board managers that can design and implement a performance measurement system (PMS), nor do they have an explicit overall strategy from which the PMS can be derived. The focus of this article is to develop a qualitative theoretical model on PM in supply chains to explore how to adopt PMS as a tool to implement collaboration and integration in chains. The exploratory nature of the research question determined our use of a multiple case study. Two focal firms in the agro-food sector from Spain and the Netherlands, serving a total of five different chains, illustrate...

  9. Definición y Evaluación de la dificultad del problema de secuenciación de unidades homogéneas

    Maheut, Julien; García Sabater, José Pedro; Morant Llorca, Joan; Perea, Federico
    [EN] The Car Sequencing Problem is a relevant topic both in the literature and in practice. Typ-ically, the objective is to propose exact or heuristic procedures that calculate, in a reduced computational time, a solution that minimizes the number of violated sequencing rules. However, reaching a solution that does not violate any sequencing rule is not always pos-sible because although sequencing rules should be defined to smooth the workload, the evo-lution of the production mix or some other characteristics can influence the quality of the solutions. In this paper, a first definition of a sequencing rule difficulty is proposed and...

  10. Data-driven simulation methodology using DES 4-layer architecture

    SÁEZ MÁS, AÍDA; García Sabater, José Pedro; Morant Llorca, Joan; Maheut, Julien
    [ES] n este trabajo presentamos una metodología para la construcción de modelos de simulación data driven para plantas de fabricación. Se ha ido más allá de lo propuesto en otras investigaciones al enfocar el desarrollo del modelo como una arquitectura de 4 capas (red, lógica, base de datos y realidad visual). La capa de Red abarca toda la infraestructura del sistema. La capa Lógica incluye el sistema de planificación y control de operaciones, y el sistema de manejo de materiales. La Base de Datos alberga toda la información necesaria para que represente la simulación, los resultados utilizados para analizar y...

  11. The Praktikum UPV Campus: Stretching closer ties between research at the university and students in secondary school

    Conejero, J. Alberto; Garcia-Sabater, Jose P.; Maheut, Julien; Marin-Garcia, Juan A.
    [EN] The Praktikum UPV Campus is a huge internship program geared to students still in secondary education that permits them to develop a project within research groups of the Universitat Politècnica de València (UPV). Along that week, the students participating in the program document their projects in blogs. Once the projects are over they also record some videos in which they present their work and their findings. During the next year, these students presents their material to their respective classmates, still in the secondary school, showing examples of what they can already do at the university. The Praktikum UPV Campus...

  12. Reglas de secuenciación en el problema de secuenciación en línea de montaje con mezcla de modelos

    Maheut, Julien; García Sabater, José Pedro
    [EN]The Sequencing problem of Mixed-Model Assembly Line is discussed in the literature considering constraints in form of sequencing rules. The designed algorithms pretends not to violate those rules because rules violation adversely affects the activity on the assembly line. In most part of the literature, these rules refer to physical considerations of the line or are related to workload concerns. In this paper, a novel classification of the different existing and known sequencing rules and practical examples of the industrial practice are introduced.

  13. Publishing in two phases for focused research by means of "research collaborations"

    Marin-Garcia, Juan A.
    [EN] We present and justify a new way to research and publish. This proposal is not intended to substitute or replace traditional ways of doing science, but rather complement, filling a gap and providing an efficient way to achieve scientific advances. The process begins with the sending a proposal of protocol to WPOM. Proposals are evaluated in each of the collaborations, depending on the potential to fill a research niche in the area. In the case of accepted protocols, WPOM guarantees commitment to publish the article if the protocol and deadlines are met. Thus, researchers can develop their projects focusing...

  14. Protocol: Comparing advantages and disadvantages of Rating Scales, Behavior Observation Scales and Paired Comparison Scales for behavior assessment of competencies in workers. A systematic literature review

    Marin-Garcia, Juan A.; Ramirez Bayarri, Lucia; Atarés Huerta, Lorena
    [EN] This is the protocol for a review and there is no abstract. The objectives are as follows: Identify the characteristics of each of the types of scale and how they differ from each other. Estimate the extent to which they are used by organizations in the assessment of skills of their employees. Summarize the advantages and disadvantages of each. Propose which of them would be more appropriate for assessing the competence of innovation in people (performance evaluation, promotion of workers, recruitment, etc.) and the mode of administration (self, peer, expert assessment).

  15. Estudio de la configuración productiva de una planta de pre-montaje de unidades aplicando parámetros de presencia máxima de opciones

    Maheut, Julien; Morant Llorca, Joan; García Sabater, José Pedro
    [EN] In this paper, a " pull " system to solve the problem of sequencing homogeneous units is defined. The literature and practice usually address this problem of " Push" mode in which an intelligent system calculates the next unit that the system must produce according to what is available . The proposed method suggests that the plant is fed with production orders (unit by unit) versus those that remain in the plant ( or rather those than miss). The case study of an assembly factory in which a new pre-assembly plant with parallel lines and alternate routings and pull...

  16. Educación para el Desarrollo Sostenible en asignaturas de Dirección de Operaciones. El caso del Banco de Alimentos de La Rioja

    Queiruga, Dolores; González Benito, Javier; Rocha Valencia, Luz Amira; Lannelongue Nieto, Gustavo
    [EN] Education for Sustainable Development at university level involves achieving certain skills as liability or personal involvement in social issues. We present a practice in the subject of Operations Management two degrees: Engineering and Labor Relations and Human Resources, at University of La Rioja. To do this, we use four teaching activities, applied to the case of the Food Bank. These are: guided tour of the storehouse, practical lesson in the computer room with cooperative learning, oral presentation (with peer assessment using a rubric) and voluntary participation in a campaign to collect food.
