Caracterización de la gestión del mantenimiento de equipo biomédico en servicios de urgencia de clínicas y hospitales de Medellín en el período 2008-2009

La gestión de mantenimiento es una herramienta de gran impacto que apoya al personal de Ingeniería en el desarrollo, control y dirección de programas de mantenimiento para el equipo médico. Objetivo: caracterizar la gestión de mantenimiento en servicios de urgencia de clínicas y hospitales del área metropolitana de Medellín en el período 2008-2009. Materiales y métodos: se realizó una encuesta a jefes y técnicos de mantenimiento en once entidades prestadoras de servicios de salud, clasificadas en tercer nivel y pertenecientes a la red de salud del municipio de Medellín. Resultados: entre las instituciones encuestadas se encontró que la causa de falla más común en los equipos del servicio de urgencia es el mal manejo de los equipos (75%) por partede los operarios y que 70% del mantenimiento es realizado por personal con experiencia en el área (tecnólogos en mantenimiento de equipo biomédico e ingenieros biomédicos). En las once instituciones públicas y privadas encuestadas se halló que solo se contaban con cronogramas de mantenimiento y/o con información desactualizada concerniente a las hojas de vida de los equipos, planes de mantenimiento o adquisición y baja de equipos. Conclusión: el estudio muestra la existencia de debilidades en ciertos puntos de la gestión, incluyendo mala organización, poca disponibilidad de repuestos originales y falta de capacitación en el personal que maneja los equipos.

La experiencia de los receptores en el trasplante de órganos y tejidos

El trasplante de órganos y/o tejidos es considerado como una opción terapéutica viable para el tratamiento tanto de enfermedades crónicas o en estadios terminales, como de afectaciones no vitales, pero que generen una disminución en la calidad de vida percibida por el paciente. Este procedimiento, de carácter multidimensional, está compuesto por 3 actores principales: el donante, el órgano/tejido, y el receptor. Si bien un porcentaje significativo de investigaciones y planes de intervención han girado en torno a la dimensión biológica del trasplante, y a la promoción de la donación; el interés por la experiencia psicosocial y la calidad de vida de los receptores en este proceso ha aumentado durante la última década. En relación con esto, la presente monografía se plantea como objetivo general la exploración de la experiencia y los significados construidos por los pacientes trasplantados, a través de una revisión sistemática de la literatura sobre esta temática. Para ello, se plantearon unos objetivos específicos derivados del general, se seleccionaron términos o palabras claves por cada uno de estos, y se realizó una búsqueda en 5 bases de datos para revistas indexadas: Ebsco Host (Academic Search; y Psychology and Behavioral Sciences Collection); Proquest; Pubmed; y Science Direct. A partir de los resultados, se establece que si bien la vivencia de los receptores ha comenzado a ser investigada, aún es necesaria una mayor exploración sobre la experiencia de estos pacientes; exploración que carecería de objetivo si no se hiciera a través de las narrativas o testimonios de los mismos receptores

Análisis de los componentes de la cadena de suministro y su relación con el desempeño superior de la organización en el sector manufacturero

En este documento se evidencia como el desempeño organizacional de una empresa, entendido como el rendimiento superior de la misma, se ve modificado por las prácticas o metodologías utilizadas, aplicadas e integradas a cada uno de los componentes de la Cadena de suministros. Es así que el propósito principal es demostrar cual es la relación entre los componentes de la Cadena de Suministros y su gestión sobre los rendimientos económicos de la empresa. De esa manera se encontraron múltiples actividades que toman lugar en los procesos característicos de cada uno de los componentes de la cadena de suministros y que al final nos presentan una variabilidad sobre los rendimientos de la empresa. Cabe recalcar que la investigación se realizó con respecto a empresas pertenecientes al sector manufacturero y abarca una buena parte de este. La importancia que tiene la investigación, es el haber entregado como resultado, el conocimiento sobre algunas de las practicas más utilizadas en el sector en cada uno de sus componentes, lo cual hace de la Cadena de suministros, un factor por excelencia para ser tratado e implementado con el fin de alcanzar mayores rendimientos económicos a nivel de empresa. En la investigación se utilizaron los casos de empresas reales tanto nacionales como internacionales y se encontraron situaciones claves que evidenciaban la hipótesis de la relación entre la cadena de suministros y el desempeño organizacional. Es por ello, que si bien es ahora cierto, que las actividades desarrolladas en los componentes de la Cadena de Suministros de las empresas influyen en el incremento de los rendimientos, es importante que las empresas conozcan de esta información para tener una idea de cómo desarrollar ventajas competitivas que los posicionen como empresa y les genere entonces mayores rendimientos, o por el contrario, les genere ahorros en costos y por ende altos beneficios y nuevas inversiones en prácticas que a la larga volverá a la empresa en un organismo eficientes y próspero.

Bättre utnyttjande av nya och befintliga förrådslokaler på SSAB Tunnplåt

The purpose of this assignment at SSAB Tunnplåt in Borlänge was mainly to investigate and describe the circumstances for the spare parts stored in storage facilities within the area of operation. Even new facilities which could serve as storage rooms and their opportunities for storing spare parts were an important part of the investigation. This because of the need for improved storing of spare parts. Furthermore, market offers where reviewed for storage of spare parts in more tailored designs. The work will culminate in proposals for improvement which is of importance for the development surrounding the storage and handling of spare parts. This is since the design and management of existing storage facilities is not perceived as satisfactory with regards to spare parts characteristics. Moreover, the amount of stock locations is too few in relation to the actual need. The approach used to achieve objectives of the work was an advanced mapping for collection of vital data. The mapping consisted of interviews with involved parties, both internal and external, for the most comprehensive picture of the problems as possible. In addition, a literature survey was conducted to identify possible options for the objectives of the work as well as a personal study of existing and new storage facilities. Furthermore, the market offers for improved conditions in storage rooms were examined. A clear picture of internal logistics and warehouse activities for spare parts at SSAB Tunnplåt has been obtained during this work. From this picture, it is concluded that work in and around storage facilities can be made more efficient. SSAB Tunnplåt should additionally make efforts in the storage facilities for better use of the available storage space. A number of proposals for improvement for each studied storage facility and spare parts management in general have been conducted. These proposals for improvement include presentations to improve the design of the studied storage facilities towards enabling more stock locations. The proposals also include additional equipment for handling spare parts, scrap handling, as well as expansions of the maintenance system which supports activities in the spare parts management.

An approach to evaluate product verifications

Companies implement a module product assortment as a part of their strategy to, among others, shorten lead-times, increase the product quality and to create more product variants with fever parts. However, the increased number of variants becomes a challenging task for the personnel responsible for the product verifications. By implementing verifications at module level, so called MPV (Module Property Verification) several advantages ensue. The advantages is not only a decrease in cost of verifications, but also a decrease in repair times, occupied space, storages with spare parts, and repair tools. Further, MPV also give an increased product quality due to an increased understanding of which defects that may occur. As an approach to implement MPV, this paper discusses defects and verification processes based on a study at a Swedish company. It also describes a matrix which is used to map relations between company specific cost drivers and so called verification factors. The matrix may indicate cost drivers which have a large impact on the total cost of product verifications.

An empirical test of the gravity p-median model

A customer is presumed to gravitate to a facility by the distance to it and the attractiveness of it. However regarding the location of the facility, the presumption is that the customer opts for the shortest route to the nearest facility.This paradox was recently solved by the introduction of the gravity p-median model. The model is yet to be implemented and tested empirically. We implemented the model in an empirical problem of locating locksmiths, vehicle inspections, and retail stores ofv ehicle spare-parts, and we compared the solutions with those of the p-median model. We found the gravity p-median model to be of limited use for the problem of locating facilities as it either gives solutions similar to the p-median model, or it gives unstable solutions due to a non-concave objective function.

Testing the gravity p-median model empirically

Regarding the location of a facility, the presumption in the widely used p-median model is that the customer opts for the shortest route to the nearest facility. However, this assumption is problematic on free markets since the customer is presumed to gravitate to a facility by the distance to and the attractiveness of it. The recently introduced gravity p-median model offers an extension to the p-median model that account for this. The model is therefore potentially interesting, although it has not yet been implemented and tested empirically. In this paper, we have implemented the model in an empirical problem of locating vehicle inspections, locksmiths, and retail stores of vehicle spare-parts for the purpose of investigating its superiority to the p-median model. We found, however, the gravity p-median model to be of limited use for the problem of locating facilities as it either gives solutions similar to the p-median model, or it gives unstable solutions due to a non-concave objective function.

Modelo de gerenciamento de estoques de peças de reposição para empresas de transporte urbano de passageiros

This work searches to offer a model to improve spare parts stock management for companies of urban passenger transport by bus, with the consequent progress in their maintenance management. Also known as MRO items (Maintenance, Repair and Operations), these spare parts, according their consumption and demand features, cost, criticity to operation, lead-time, quantity of suppliers, among other parameters, shouldn´t have managed their inventory like normal production items (work in process e final products), that because their features, are managed by more predictable models based, for example, in economic order quantity. In the case specifically of companies of urban passenger transport by bus, items MRO have significant importance in their assets and a bad management of these inventories can cause serious losses to company, leading it even bankrupticy business, in more severe situations which missing spare part provokes vehicles shutdown indefinitely. Given slight attention to the issue, which translates in little literature available about it when compared to that literature about normal items stocks, and due the fact that MRO items be critical to bus urban transport of passengers companies´, it is necessary, so, deepen in this theme searching to give technical and scientific subsidies to companies that work, in many times, empirically, with these so decisive inputs to their business. As a typical portfolio problem, in which there are n items, separated into critical and noncritical, while competing for the same resource, it was developed a new algorithm to aid in a better inventory management of spare parts used only in corrective maintenance (whose failures are unpredictable and random), by analyzing the cost-benefit ratio, which compares the level of service versus cost of each item. The model was tested in a company of urban passenger transport by bus from the city of Natal, who anonymously provided their real data to application in this work

Uma contribuição à avaliação dos impactos da gestão de estoque na satisfação e fidelização pós-vendas de clientes de concessionárias de automóveis : um estudo empírico em Natal-RN

This paper aims to conduct a study to evaluate and measure the possible impact that the unavailability of spare parts can have on customer satisfaction for car dealerships in the post-sales. A theoretical-conceptual review on the subject of satisfaction and loyalty, on the backdrop of the reality of the automobile market, allowed the construction of a research tool dedicated to collect opinions of car owners, to allow an analysis empirical relationship between the availability of parts, repairs or scheduled service possible, and change or stay on the mark on the occasion of change of vehicle. 236 forms were applied to car owners in the city of Natal / RN. The results obtained in this survey allowed the identification of the unavailability of parts as a significant factor, among others, the motivation for the customer to switch brands. Collaterally, we could also conclude that the dynamics of change in marks, whatever its motivation, is reflected in the perceived positions of the different brands as the market share both in strictly quantitative terms and in terms of relative positioning, with significant changes in the ranking of consumer preferences for different brands available

A New Approach for Real Time Fault Diagnosis in Induction Motors Based on Vibration Measurement

Condition monitoring is used to increase machinery availability and machinery performance, reducing consequential damage, increasing machine life, reducing spare parts inventories, and reducing breakdown maintenance. An efficient real time vibration measurement and analysis instruments is capable of providing warning and predicting faults at early stages. In this paper, a new methodology for the implementation of vibration measurement and analysis instruments in real time based on circuit architecture mapped from a MATLAB/Simulink model is presented. In this study, signal processing applications such as FIR filters and fast Fourier transform are treated as systems, which are implemented in hardware using a system generator toolbox, which translates a Simulink model in a hardware description language - HDL for FPGA implementations.
