Aggregate planning for staff and material transportation in the oil and gas sector
No full textThe objective of this study was to develop an aggregated planning for the transportation of personnel and material in a hydrocarbon sector company, using a company located in Peru as a case study. In the analysis, two key strategies were evaluated: chasing and leveling, applied to different modes of transportation, such as fixed wing, rotary wing, river and land. Through this analysis, it was observed that the chasing strategy proved to be the most appropriate for the company, since it not only presents lower operating costs compared to the leveling strategy but also allows them to meet the monthly demand accurately, which facilitates effective planning for the next year, based on the results obtained from the aggregate planning.Este estudio tuvo como objetivo desarrollar una planificación agregada para el transporte de personal y material en una empresa del sector de hidrocarburos, utilizando como caso de estudio a una empresa ubicada en Perú. En el análisis, se evaluaron dos estrategias clave: persecución y nivelación, ambas aplicadas a distintos modos de transporte, como ala fija, ala rotatoria, fluvial y terrestre. A través de este análisis, se observó que la estrategia de persecución resultó ser la más adecuada para la empresa, ya que no solo presenta menores costos operativos en comparación con la estrategia de nivelación, sino que también permite cumplir con la demanda mensual de manera precisa, lo que facilita una planificación efectiva para el próximo año, basada en los resultados obtenidos de la planificación agregada
An Assessment of How Urban Crime and Victimization Affects Life Satisfaction
No full textWe assess the effect of the homicide rate, individual´s perception of security in their neighborhood of residence, and of the effect of their having been victimized, on life satisfaction. We find a negative effect of the homicide rate on life satisfaction for the subsample of individuals living in their current houses for at least 10 years or more, who had moved to that place at some point in the past. We also find a positive and robust effect of the perception of security in the households´neighborhood for the whole sample, and for different subsamples considered. Having been victim of an offense is also robustly negatively related to life satisfaction, in particular in the cases where the offense was robbery.Quality of Life, Life Satisfaction, Crime.
