Modelo de plan estratégico para la gestión de inventarios para los repuestos John Deere de Ponce Yepes S.A.

En el presente trabajo se propone un modelo de plan estratégico, cuya aplicación se sugiere en la empresa Ponce Yepes S.A., con el objetivo de conseguir una eficiente y eficaz gestión de inventarios para la Línea de Repuestos John Deere. El estudio se ha dividido en tres capítulos, en los cuales se van estructurando progresivamente las diferentes etapas para el establecimiento del plan estratégico que se propone. El primer capítulo contiene un resumen teórico sobre la administración de inventarios, los conceptos, la clasificación y los modelos más difundidos. En el segundo capítulo se realiza el análisis de la situación actual de la empresa, enfocado a la Línea de Repuestos John Deere. Este capítulo incluye el análisis del entorno, el esquema de funcionamiento actual del sistema de inventarios, el análisis FODA, la determinación de los clientes internos y externos con sus correspondientes demandas, la elaboración y análisis de las matrices de evaluación de factores internos y externos, en forma individual y combinada; y, se presentan las listas de las estrategias a aplicarse. En el tercer capítulo se presenta la estructuración del plan estratégico, que está compuesto por la reformulación de la misión y visión, el establecimiento de objetivos globales para la gestión de repuestos John Deere, la formulación de las estrategias y políticas para alcanzar dichos objetivos y se concluye detallando el plan operativo, el cual incluye la matriz de aplicación del plan operativo, el cronograma de cumplimiento, el modelo de evaluación y seguimiento de dicho plan, y el flujo de caja del presupuesto de costos. Finalmente se presentan las conclusiones y recomendaciones resultantes del modelo de plan estratégico propuesto.

Dr John Snow and an early investigation of groundwater contamination

John Snow was a physician but his studies of the way in which cholera is spread have long attracted the interest of hydrogeologists. From his investigation into the epidemiology of the cholera outbreak around the well in Broad Street, London, in 1854, Snow gained valuable evidence that cholera is spread by contamination of drinking water. Subsequent research by others showed that the well was contaminated by sewage. The study therefore represents one of the first, if not the first, study of an incident of groundwater contamination in Britain. Although he had no formal geological training, it is clear that Snow had a much better understanding of groundwater than many modern medical practitioners. At the time of the outbreak Snow was continuing his practice as a physician and anaesthetist. His casebooks for 1854 do not even mention cholera. Yet, nearly 150 years later, he is as well known for his work on cholera as for his pioneering work on anaesthesia, and his discoveries are still the subject of controversy.

The impact of climate change on daily precipitation statistics for Jordan and Israel

A regional climate model is used to investigate changes in Israel and Jordan precipitation at the end of the 21st century on daily to monthly timescales. The model predicts that this region will get significantly drier at the peak of the rainy season, reflecting a reduction in both the frequency and duration of rainy events. These changes may be associated with a reduction in the strength of the Mediterranean storm track

A model-based assessment of the effects of projected climate change on the water resources of Jordan

This paper is concerned with the quantification of the likely effect of anthropogenic climate change on the water resources of Jordan by the end of the twenty-first century. Specifically, a suite of hydrological models are used in conjunction with modelled outcomes from a regional climate model, HadRM3, and a weather generator to determine how future flows in the upper River Jordan and in the Wadi Faynan may change. The results indicate that groundwater will play an important role in the water security of the country as irrigation demands increase. Given future projections of reduced winter rainfall and increased near-surface air temperatures, the already low groundwater recharge will decrease further. Interestingly, the modelled discharge at the Wadi Faynan indicates that extreme flood flows will increase in magnitude, despite a decrease in the mean annual rainfall. Simulations projected no increase in flood magnitude in the upper River Jordan. Discussion focuses on the utility of the modelling framework, the problems of making quantitative forecasts and the implications of reduced water availability in Jordan.
