    Aplicación de la metodología TOC al estándar PMI ®
    (2014-05-13) Cuartas-Montoya, C. M. (Claudia Marcela); Lopera-Zapata, R. G. (Robinson Gerardo)
    Existen varios estándares y metodologías para la gestión y administración de proyectos; en Colombia y, en general, en Estados Unidos y América Latina la más utilizada es la dictada por el PMI®; sin embargo, en ocasiones con el uso indebido de las metodologías tradicionales de gestión de proyectos, la probabilidad de presencia de problemas relacionados con el costo, el tiempo o el alcance del proyecto es muy alta, lo que hace necesario desarrollar una nueva metodología, o definir los cambios que se deben realizar sobre la utilizada, para mejorar los resultados de los proyectos y disminuir considerablemente la probabilidad de surgimiento de problemas. Una metodología que muestra buenos resultados en la ejecución de los proyectos es la teoría de restricciones, por lo cual es interesante intentar incorporarla en los estándares del PMI®. Para lograr esto, se estudiaron las áreas de conocimiento de gestión del tiempo y gestión del costo presentadas por el estándar del PMI®. Posteriormente, se definió la forma como se les debe aplicar la teoría de restricciones en cuanto a la creación de los cronogramas y uso de amortiguadores al final de la cadena crítica y las rutas alimentadoras.

    Aplicación de la teoría de restricciones (TOC) a los procesos de producción de la planta de fundición de Imusa
    (2014-05-13) Abisambra-Lemus, A. J. (Abraham José); Mantilla-Cuadros, L. A. (Luis Andelfo)
    The plant of smelting of IMUSA S.A., like many productive plants of the metal mechanics sector that export their products, has complex and changing processes that, in addition to being flexible to the different exigencies from the market, must be prepared for a constantly variable demand. In this paper the present situation of the smelting plant is described and a practical application for the reduction of inventories, the improvement of the cash flow and capital under the methodology is formulated by Theory of Constraints TOC. This paper becomes a guide for the possible improvements that can be obtained in a plant, following the stages of TOC and using the resources at the correct moment. This work is based on a particular plant, but the improvements and changes can be applied to any industrial or service sector.

    Desarrollo e implementación de un modelo de teoría de restricciones para sincronizar las operaciones en la cadena de suministro
    (2013-10-23) Marín-Marín, W. (William); Gutiérrez-Gutierrez, E. V. (Elena Valentina)
    This paper presents a methodological and practical proposal to synchronize the logistic operations and decisions in a Colombian ceramic tile supply chain. For doing so, we used two tools from the Theory of Constraints methodology (TOC): the first one refers to the operations synchronization along the supply chain through the so-called method Drum-Buffer-Rope; the second one refers to the development of an accounting tool that allows improving the decision making for each member of the supply chain (Throughput Accounting). The results of the implementation show that an integral analysis of the supply chain could improve the global performance metrics such as service level, production plans fulfillment, inventory costs of raw materials and finished goods, and the company productivity.

    Diseño de procesos operativos mediante la metodología de teoría de restricciones en el Parque Explora Medellín
    (2014-05-13) Urreta-Arango, J. A.( Jorge Andrés); Aristizábal-Sorza, M. (Mauricio)
    The Theory of Constraints (TOC) represents a valuable tool for the systemic improvement of processes since it helps in the identification and efficient use of restrictive resources and, therefore, in the productivity increase of the global system. Due to its effective application in the production field, TOC has widely demonstrated not only its strength, but also its use in the services area, particularly in logistics and management operations. Nowadays, it is considered an important tool for the continuous improvement which generates better results for organizations. This study tries to obtain the maximum benefit in terms of operations planning and visitors flow. TOC, was applied to Parque Explora, an interactive museum of science and technology, opened to the public at the end of 2007 and will certainly become a supporting instrument for the application and dissemination of science and technology in the city of Medellín.

    Gestión de Proyectos con Teoría de Restricciones aplicada al área técnica de la Compañía Construcciones y Servicios S. A.
    (2014-05-13) Gómez-Posada, L. F. (Luis Felipe); Jiménez-Villalobos, J. B. (Juan Bernardo)
    The Dinpro-Construcciones y Servicios group is oriented towards the design, construction, assembly and maintenance of industrial and logistic projects; “Construcciones y Servicios” company focuses in the construction, assembly, and maintenance of these projects; this article is developed at this company. One of the most important activities within the execution of construction projects is to ensure that the contractors are well prepared to execute that which was agreed, in the scheduled moment and with the arranged characteristics, but to hire on time before the starting day of the each activity depends of the work team. Nevertheless, there are no follow up and control tools which allow assuring the efficacy of the hiring process so that it is done on time in the field. This essay pretends to display the experience of “Construcciones y Servicios” S.A. in the application of the solutions granted elements for the General Management of TOC Projects (Critical chain) to the hiring process, executed as a project per se with successful results.

    Toma de decisiones rentables mediante la contabilidad del trúput en una lavandería industrial
    (2014-05-13) Pérez-Henao, C. (Catalina); Arcos-Henao, L. F. (Luis Fernando)
    This paper presents a new approach for the decision making in an industrial laundry by the application of throughput accounting under the focus of the theory of constraints (TOC). The restriction in the system was identified by a detailed analysis of the special washing processes and their capabilities. We made in every process the octane analysis speed of throughput, identifying the line that generates more speed in turnover and hence to which it should be given more strength in sales to fill the capacity that is available; this is because with the current demand the restriction was in the market. With the simulation of various combinations among the three processes, tainted, washed and crafts, taking into account the octane already calculated by product, it was found that without an increase in operational costs and without locative or technological investments, sales can be increased by 70% in relation to what the company is currently billing.
