Implementacion de un software para el control de neumaticos como herramienta de mejora en la gestion del mantenimiento de una flota de camiones

101 p.La presente memoria de titulo se basa en la implementación del Software Rodar System III para el control de neumáticos, y se aplica a la flota de camiones pertenecientes a la planta Teno de la Sociedad Depetris Deflorian Hnos. Ltda. La constante competencia comercial existente, hace que cada día se busquen nuevos métodos para ampliar el margen de ganancias de las organizaciones, es por esto que surge la necesidad de maximizar la vida de los activos físicos de la empresa. En el caso de los neumáticos estos son un centro de costos que generan altas demandas de recursos económicos por lo que realizar rutinas de mantenimiento y controles eficaces y eficientes dirigidos a estos elementos, es el principal motivo por el cual se decidió integrar una herramienta informática que facilite estas labores y permita obtener el mayor desempeño posible de dichos componentes. Para el desarrollo de este trabajo fue necesario definir los flujos de información necesarios para alimentar la base de datos del sistema de información utilizado (Rodar System III). Como etapa inicial se trabajó en la elaboración de planillas mediante las cuales fuese posible la recolección de datos para el posterior ingreso al sistema. Junto con esto se realizó un levantamiento para poder registrar y evaluar el estado actual de los neumáticos del total de la flota. Así mismo y en vista de las falencias detectadas en las labores de mantenimiento dirigidas a los neumáticos fue necesario establecer procedimientos de trabajo mediante los cuales se establecen criterios y condiciones para realizar mantenimiento preventivo, además de definir las condiciones para que una vez retirados los neumáticos sea viable la reutilización de este mediante el proceso de recapado. En definitiva con la implementación del software Rodar System III, se busca tener una herramienta de apoyo en el proceso de toma de decisión y que combinado con rutinas de mantenimiento preventivo se logre minimizar los costos operacionales de la flota./ ABSTRACT: This work is based on the implementation of the software Rodar System III for the control of tires, and it is applied to the fleet of trucks belonging to the plant Teno of the Society Depetris Deflorian Hnos. Ltda. The constant commercial competition makes that every day new methods are looked for to enlarge the margin of earnings of the organizations, it is for this reason that the necessity arises of maximizing the life of the physical assets of the company. In the case of the tires these they are a cost centre that generate discharges demands of economic resources for that that to carry out maintenance routines and effective and efficient controls directed to these elements, it is the main reason for which decided to integrate a computer tool that facilitates these works and allow to obtain the biggest acting possible of this components. For the development of this work it was necessary to define the necessary flows of information to feed the database of the utilized system of information (Rodar System III), as initial stage one worked in the elaboration of schedules by means of which was possible the gathering of data for the later entrance to the system. Together with this he/she was carried out a rising to be able to register and to evaluate the current state of the tires of the total of the fleet. Likewise and in view of the lack detected in the managed maintenance works to the tires it was necessary to establish working up by means of which approaches and conditions settle down to carry out preventive maintenance, besides defining the conditions so that once retired the ti res are viable the re-use of this by means of the retreading process. In definitive with the implementation of the software Rodar System III, it is looked for to have a support tool in the process of taking of decision and that combined with preventive maintenance routines it is possible to minimize the operational costs of the fleet. Key Words: Rodar System III, system of information, maintenance, physical assets, tires

System Dynamics as a tool for Green Supply Chain Management: A Theoretical Ransom

Abstract Under sustainable development pressures, organizations have to consider the relationship between the environment and activities of supply, production, distribution, consumption and disuse, which is known as "green supply chain management" (GSCM). The article presents an overview of research work in these areas, followed by an introduction of the green concept in SCM resorting to System Dynamics (SD). The research method was based on an extensive literature review to describe the simulation-based framework of SD modeling. Simulation approach enables performance to be analyzed from a variety of organizational perspectives. There is a critical need for gaining a deeper understanding of the impact of decisions on operations; it is a conclusion of the study. Simulation has been found to be one of the popular and suitable mechanisms for understanding Supply Chain Dynamics

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection
