- Targeting the Promotion of Incubating SMEs Competencies Through the Integration of a Business Incubation Process with a Virtual Enterprise Creation Process-Edición Única(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2009-07-01) Rodrigo Márquez Castillo; Molina Gutiérrez, Arturo; Pérez Guardado, Miguel Ángel; Espadas Pech, Javier Mijail; Tecnológico de Monterrey, Campus Monterrey; Acevedo Mascarúa, JoaquínNowadays, Small and Medium Enterprises (SMEs) represent most of the income in the economies around the World. In spite of their undeniable importance, SMEs are highly prone to fail, in Mexico for example: around 90% of the SMEs go bankrupt before reaching their first year of existence, and this problem is caused very often by the little effectiveness of the companies to commercialize their products and/or services. On the other hand, due to their informality and size, SMEs are managed generally by their owners, who usually lack of managing skills though they stand-out in operative-oriented skills caused by their closeness to company’s daily operation. This situation represents a threat for the existence of SMEs because of the need of developing business skills in order to sell their products and/or services. The competency-based collaboration, achieved through a Virtual Enterprise creation process, allows companies to promote their competencies in the same way as they promote their products and services; this kind of collaboration generates two important advantages for companies, the first one is the raise in the number of markets they will be able to reach and the second one is their involvement in collaboration business opportunities. Companies that belong to incubation stages are prone to adopt a schema of collaboration based-on competencies integration because incubation is the time when companies define important aspects like products and services that they will offer to the market and the competencies required to produce them. In order to allow incubating companies to collaborate using a competency-based collaborative model, this research work proposes the integration between the ITESM business incubation model and the Virtual Enterprise creation process developed by ECOLEAD project. To achieve the proposed integration a modeling exercise including the ITESM business incubation processes and the Virtual Enterprise creation process using Business Process Modeling Notation (BPMN) and Business Process Integration concepts was carried-out. Finally, it was developed a prototype tool implementing the business process integration previously described. This tool was designed using a Service Oriented Architecture (SOA) to facilitate the implementation of the Web Services needed to carry-out the proposed integration.
- Reference Model and Methodology to Improve the Product Development Process-Edición Única(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2007-05-01) Nicolás Enrique Peñaranda Verdeza; Molina Gutiérrez, Arturo; Guerra Zubiaga, David; Ramirez Mendoza, Ricardo; ITESM-Campus Monterrey; Ángel Bello, FranciscoProduct development managers are looking for new ways to improve their product development process. Emerging concepts and solutions as Product Lifecycle Management (PLM), which is based on Concurrent Engineering (CE), carries out this improvements, achieving reductions in time and cost in the product development process. However, there is a lack of a particular reference model and methodology to achieve a successful PLM implementation within companies. Enterprise Integration Engineering (EIE) is a reference model that can be used to develop a particular reference model for the product development process. This reference model for product development aligns the enterprise strategies with the use of product development tools in order to impact key performance indicators in the company. Also, EIE reference model helps to define strategies, evaluate performance measures, design/re-design processes and establish the enabling tools and technologies. However, a reference model doesn’t have a methodology to implement systematically these changes in the company. For this reason, Action Research (AR) is used to guide the improvement of the product development process, proposing changes in the resources, organization, functional (process model) and information model. AR is customized, defining specific activities for each cycle developed. It is necessary to demonstrate this methodology using a case study, which is used to validate the benefits of this methodology proposed. This case study is developed in a Mexican company, which have the interest to improve its product development process. Final Conclusions are described based on the experiences in the implementation of this methodology. These conclusions are based on the technological and human resources, information, organization and functional changes developed in the case study. Current Technologies can reach a complete Product Lifecycle Management, however previous works are demonstrated that just implement technological resources do not guarantee an improvement of the product development. For this reason, in this thesis is highlighted the necessity to use a methodology that also propose changes in the company organization and product development activities. Finally, Impacts and benefits to implement these improvements are evaluated.
- An Instantiation Methodology for Virtual Breeding Environments Management-Edición Única(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2007-03-01) Romero Díaz, David C.; Molina Gutiérrez, Arturo; Galeano Sánchez, Natalie; Ramírez Mendoza, Ricardo; ITESM-Campus Monterrey; Dieck Assed, GracianoVirtual Organization Breeding Environments (VBEs) are long-term cluster/associations of autonomous, geographically dispersed and heterogeneous organizations. The VBE aims to prepare its member’s organizations and support institutions, and enhance their readiness for potential involvement in collaboration opportunity-based Virtual Organizations. A Virtual Organization (VO) is defined as a temporally association of (legally) independent organizations that come together to share skills and resources to achieve a common goal, such as preparing a proposal (or a bid), or jointly performing the tasks needed to satisfy a market/society opportunity by co-producing products/services for the customer, and whose cooperation is supported by computer networks. Effectively managing of a Virtual Breeding Environment (VBE) is bound to the objective of preparing VBE members and maintaining this preparedness for collaboration in a Virtual Organization (VO). As such, preparedness is a strategic item that requires time to be established and must be refreshed and maintained throughout the entire VBE life cycle. Implementing and efficiently managing a VBE helps to shrink VO set-up times in contrast to selecting enterprises from an “open universe” of enterprises that never collaborated before. Collaboration Opportunities (CO) can be captured much faster and more reliably when using means of a VBE. Keeping enterprises prepared for collaboration requires management of various kinds of information and business processes. The VBE Management Framework proposed in this thesis is designed to depict all the management business processes needed to create, operate/evolve, metamorphe and dissolve a VBE according to the models and concepts developed within ECOLEAD project. The VBE Management Framework has the objective to give a prioritization of all VBE management processes to be supported by human or information system interactions through VBE life cycle. Finally, a VBE Instantiation Methodology, as a set of guidelines and suggested tools, is proposed to instantiate the VBE Management Framework in different Virtual Breeding Environments domains
- A Reference Model Instantiation to Develop a Methodology from Mechatronic Product Desig: In Wireless Sensor Network Application -Edición Única(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2006-05-01) Delgado Arcos, Roberto Cristian; Molina Gutiérrez, Arturo; Guedea Elizalde, Federico; Céspedes Mota, Armando; ITESM-Campus Monterrey; Viramontes Brown, Federico A.Currently the process of manufacturing has been changed according to the customer’s requirements. Actual trends in manufacturing, such as mass customization, shorter product life, frequent of changes of design, small inventory restrictions, legal restrictions (energy, environment pollution), etc., presses to companies to employ different technologies in order to be more competitive and efficient. Recently, the industry has been developed some concepts to overcome current currently challenges. For example: process automation (PA), factory automation (FA), flexible manufacturing systems (FMS), reconfigurable manufacturing systems (RMS) etc., but these concepts need some technologies for achieving the best performance and ensuring product quality. Sensors are fundamental devices or systems in the automation process. Sensors and the sensor systems must work with some performance; the performance are based in electrical, electronic and mechanical characteristics (accuracy, repeatability, small size, low power consumption, practical installation, frequency bandwidth, ration noise, linearity, etc.), but of single sensor is not enough for multivariable detection and conversion of industrial variables, because the number of parameters is relatively large. The Wireless Sensor Networks (WSN) have a lot of features that make them attractive such as an instrument of solution for different challenges in the actual industry or factory. This technology can achieve the new requirements in futures aspects of the manufacturing. This thesis proposes an integrated methodology for Mechatronic Product Development using the Wireless Sensor Network technology. The methodology allows to create a mechatronic product from the reference and partial model to a particular model through instantiation. The methodology is based in stages, each stage has activities performed to achieve a result in a specific process. The stages are from product planning to prototyping (product planning, conceptual design, embodiment design and prototyping) and the activities of the design process [(1) Analysis: are oriented to diagnose, define and prepare information, (2) Synthesis: are oriented to put all elements together to produce new effects and to demonstrate that these effects create an overall order. (3) Evaluation: are oriented to test those solutions against the goals and requirements] in each stage. This methodology emphasized in the coupling between each area (mechanical, electronic and software) and the electronic design. The case of study was the development a mechatronic product to demonstrate the usefulness of the methodology. The mechatronic product was an integrated product for monitoring remotely pneumatic pressure in industrial pipelines using commercial WSN, the system developed covered the mechanical design of the attaching system for the sensor. The conditioning of the electrical signal from the sensor and the programming of the sensor capabilities for remote data access and management using real-time operating system called TinyOS. The data gathered from the WSN were displayed in a personal computer (PC). The principal results obtained on this research thesis were: (1) A methodology to develop mechatronics products form the reference and partial model to particular model through instantiation (2) A case study was developed to demonstrate how to use the methodology to develop mechatronics products using Wireless Sensor Networks technology, (3) A mechatronic product for monitoring remotely pneumatic pressure in industrial pipelines with following features: small size, low power consumption, wireless data transmission, “ad- hoc” network, etc. VI Some conclusions obtained from this thesis were: (1) Although the concept of measurement physical variables using wireless technologies has been applied, the proposed solutions have not been integrated with the methodology to develop mechatronics products using Wireless Sensor Networks nor the signal conditioning and power management to integrate new Micro-Electro-Mechanical Systems (MEMS) (2) The methodology provides some benefits: fulfills the customers needs, solves some design problems, prevents some failures in design, reduces the time of design, etc. (3) The literature review showed that there are a lot of methodologies to product design. These methodologies do not provide a particular model to mechatronic product or mechatronics product based in wireless sensor network technologies (4). The case of the study helped to identify important areas of further work in power management, data sampling, communications, and software design. (5) The methodology, in this case of study, fulfilled with the objectives, but the correct validation will be based in more case of study

La industria manufacturera en México no es la excepción, el crecimiento económico e industrial de países de bajo costo ha logrado atraer la inversión, provocando una competencia en costos como nunca antes se había enfrentado. Por otro lado, los sistemas de administración modernos han permitido, a empresas que están localizadas en geografías de alto costo, operar con márgenes competitivos. En este trabajo de tesis se identificó como problema la falta de modelos y metodologías que ayuden a los directivos y a las organizaciones en la identificación, planeación y ejecución de proyectos de mejora estratégicos; optimización de recursos y medición del impacto de éstos en los indicadores del negocio. Ante dicho problema, en el presente trabajo se propone una metodología que adapta el modelo general de Zachman para la mejora e innovación de los procesos. Dicha metodología integra otras metodologías tales como: manufactura esbelta, seis sigma y work-out, entre otras; así como el uso de las herramientas conocidas por la empresa. A través de la aplicación de los conceptos de la Ingeniería de la Integración de la Empresa (EIE) se describen los pasos que comprende dicho método, así como el desarrollo de cada uno de ellos. Tras la aplicación de dicha metodología en la empresa de la industria electrónica, se comprobó y validó su eficacia. Se llevaron a término diversos proyectos de mejora que permitieron alcanzar la optimización de recursos en las unidades de negocio donde se trabajó. En conclusión, esta tesis pretende ser de utilidad para el directivo (o para quien él designe como líder de proyectos) de la industria de manufactura, dotándolo de un método sencillo para desarrollar su liderazgo, logrando los objetivos y metas trazados, en el período de tiempo estimado. La información de referencia detallada, los ejemplos de su aplicación, los resultados y otros beneficios de la implementación están incluidos en éste documento.
- Methodology for rapid mechatronic product development and manufacturing(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2003-12-01) Farias Moreno, Paola; Molina Gutiérrez, Arturo; León Rovira, Noel; Hernández Luna, Alberto; ITESM; Programa de Graduados en Ingeniería; División de Ingeniería y Arquitectura; Campus MonterreyIn today competitive world, products need to be designed to satisfy all the customer requirements that it is possible with specifications that will fulfill their needs. The design of these mechatronic products requires different disciplines because they integrate mechanical, electronic and software components which allow them to be more customers oriented. This thesis proposes an integrated methodology for Rapid Mechatronic Product Development and Manufacturing which includes the activities from product planning to prototyping and the engineering activities of the design process (Analysis, Synthesis and Evaluation). This methodology helps the designer in the product development process by specifying detailed activities, the flow of product information, methods that can be applied in each phase, and some other organizational issues. This methodology sets the foundation to create a generic template in order to allow the integration of the design methodology to the company own design process and also to pursue and automation of the process. The results obtained with this research are: (1) A classification of many applicable design methods and techniques by design phase and type of activity: analysis, synthesis and evaluation. (2) A methodology for rapid mechatronic product development and manufacturing. (3) A reconfigurable methodology depending on the special characteristics of the product to be developed. (4) An evaluation of design methodologies. (5) An information organization chart of the product development process for the three disciplines. A case of study of a mechatronic product was carried out in order to demonstrate the usefulness of the methodology.

- Marco de referencia para la toma de decisiones estratégicas en la administración de la cadena de suministro(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2002-12-01) López Raygoza, Pedro Daniel; Molina Gutiérrez, Arturo; Viramontes Brown, Federico; Novau Dalmau, Alberto; Cabeza Azpiazu, Luis V.; ITESM; Programa de Graduados en Ingeniería; División de Ingeniería y Arquitectura; Campus MonterreyDiscutir sobre la Administración de la Cadena de Suministro (SCM) sin mencionar la palabra "estrategia" es casi imposible. ¿Pero qué hace ese término realmente? ¿Qué constituyen las estrategias de la administración de la cadena de suministro, y cómo dan soporte a los esfuerzos de una compañía? En esta tesis, se introducen algunos conceptos cruciales en la estrategia de SCM. Las estrategias son los mecanismos por los cuales los negocios coordinan sus decisiones, estimando recursos, su estructura organizativa, sistemas de información, políticas y procedimientos. Las operaciones y las estrategias de SCM son un intento para coordinar decisiones acerca de recursos, estructura organizativa, sistemas de información, políticas y procedimientos dentro de las operaciones de la cadena. El rol estratégico es de gran importancia en SCM, la interrelación entre las diferentes decisiones estratégicas (la estrategia competitiva, la estrategia de administración de la cadena de suministro, la estrategia de producción, y el proceso de la cadena del suministro) y cómo ayudan a mejorar la operación de la cadena del suministro. El diseño e implantación de SCM requieren la definición de estrategias, los procesos, los indicadores y las decisiones mantengan una relación con los inventarios, el transporte, instalaciones e información. Esta tesis desarrolla un marco de referencia para guiar el proceso de toma de decisiones estratégico en la administración de la cadena del suministro. El proceso definirá cada uno de las actividades que ayudan a la administración de la cadena de suministro en el logro de sus cometidos.
- Factores críticos en la implementación de metodologías de outsourcing bajo el modelo "Global Virtual Enterprises"(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2002-12-01) Salazar Razo, José Apolonio; Molina Gutiérrez, Arturo; Garza Salazar, David Alejandro; Ahuett Garza, Horacio; Rodríguez González, Ciro Ángel; ITESM; Programas de Posgrado en Electrónica, Computación, Información y Comunicaciones; División de Graduados en Electrónica, Computación, Información y ComunicacionesEn el actual entorno en el que se desenvuelven las empresas manufactureras Mexicanas, se requiere de un enfoque más agresivo en lo que respecta a la forma en que satisfacen las necesidades de sus clientes. Lo anterior se debe a que actualmente estamos inmersos en el mercado libre más grande del mundo (TLC), lo cual nos exige lograr una mayor utilización de nuestros recursos, logrando una completa satisfacción de los requerimientos o necesidades de nuestros clientes. Para ello, es necesario un replanteamiento de las practicas tradicionales en un contexto de negocio que presenta nuevas variables, retos y oportunidades. Los modelos de Outsourcing nos han planteado nuevas formas de estructurar nuestros negocios teniendo la oportunidad de acceder a nuevas tecnologías, distintos" Know How" y participar con organizaciones cuyo "expertise", enlazado a nuestra cadena, nos permite llevarle a nuestros clientes un mayor valor. No obstante, en las implementaciones de estas metodologías no siempre se logran los resultados planeados, es por ello que mediante el presente documento se busca detectar cuales son los factores que minan o fomentan el éxito de éstas.
- Framework y Metodología para la Planeación e Integración de Mejores Prácticas de Manufactura y Tecnología(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2001-01-05) Medina Aguilar, Veruzcka Y.; Molina Gutiérrez, Arturo; Manríquez, Alejandro; González Velarde, José Luis; ITESMActualmente, las empresas mexicanas enfrentan una competencia cada vez más fuerte, especialmente por las cambiantes necesidades de los clientes y por la competencia que ha surgido a partir de los tratados de libre comercio con Norte América y Europa. Para mantenerse competitivas, requieren de transformarse y renovarse constantemente, adoptando nuevas prácticas de manufactura y tecnología para enfrentar exitosamente este nuevo ambiente competitivo. Como resultado de estas demandas de competitividad, las empresas se ven forzadas a tomar decisiones de manera rápida, respecto a ¿Qué prácticas de manufactura o tecnologías adoptar?, ¿Qué área requiere mayor atención?, ¿Qué indicadores hay que monitorear? Así mismo, una vez que la decisión es tomada, deben ser capaces de adaptar sus negocios, y sus recursos, tecnología y conocimiento relacionados a la nueva estrategia, de manera integrada. Con el fin de apoyar en la toma de decisiones efectiva de las empresas, en esta tesis se propone un framework y una metodología que permite evaluar, planear e integrar nuevas prácticas de manufactura y tecnología en las empresas, con apoyo de herramientas de sistemas dinámicos, simulación y modelación. El framework y la metodología propuestos consisten en 5 etapas principales: Evaluación de Empresas; Selección, Modelación y Simulación de Procesos a Mejorar (AS-IS); Selección de Mejores Prácticas y Modelación y Simulación del proceso TO-BE. Con fines demostrativos, la metodología fue desarrollada en una empresa “ideal" basada en la infraestructura del Laboratorio de Manufactura Electrónica del CSIM-ITESM. Los principales resultados obtenidos de esta investigación son: a) Desarrollo de un Framework para la planeación e integración de prácticas de manufactura y tecnología, permitiendo evaluar cambios con apoyo de modelos de referencia, metodologías y herramientas, desde un punto de vista holístico b) Desarrollo de una metodología de apoyo para la toma de decisiones, integrando herramientas específicas de dinámica de sistemas (SIMetrics), Modelación (ARIS) y Simulación (ARENA) c) Una base de datos de prácticas de manufactura analizadas en términos de modelos lógicos permitiendo conocer sus resultados, efectos, impactos y beneficios d) Un caso de estudio de una empresa “ideal" que permitió comprobar la factibilidad del uso de esta metodología en un ambiente industrial.
