El trabajo se desarrolló en las veredas San Luis de Laderas, San Antonio y San Luis de Parrados del municipio de El Calvario y San Luis de Toledo y San Luis del Plan del municipio de San Juanito, en el departamento del Meta. El presente estudio planteó la necesidad de realizar una lectura del territorio que permita comprender la interacción de las poblaciones locales con su entorno natural y social. La discusión se centró en un análisis territorial, donde se estudian y caracterizan los diferentes aspectos e inte...

Le cadre litteraire de l'oeuvre est constitue par un dialogue entre le fidele (le juif) et l'heretique (le chretien). L'introduction qui precede la traduction espagnole, propose quelques explications sur ces problemes ainsi que sur les arguments developpes par le docteur juif afin de refuter le dogme et la foi chretienne. Yosef Qimhi utilise le Pentateuque, les Psaumes, les Prophetes, la logique et la metaphysique aristotelicienne

Y esto aún que se vieran raros personajes en su parte delantera. Bien lo supo D. Juan Antonio Martínez de Castro, que inmediatamente, el día 11 del siguiente Abril, emitió un erudito informe ante la Real Academia de la Historia.

This definition can be applied to any stock policy and demand pattern, given a known stock level at the beginning of the cycle. Some approximations have been used to compute this stock level in

In the literature we find two easy-to-compute approaches: the traditional and the Hadley-Whitin approximations, but unfortunately they only apply for normally distributed demand. In practice stock managers can use any of them, even when demand is not normal or discrete. This paper assesses the performance of these approximations in a periodic inventory system for different demand scenarios such as intermittent, erratic, lumpy and smooth. However, in the discrete context, simulation results show that both approximations present a significant bias including negative fill rate values. In keeping with these results, we re-formulate both approximations to be able to cope with any discrete demand distribution and asses their performance. In this case, simulation results show that the proposed discrete formulation of the Hadley-Whitin approximation seems to avoid the systematic bias observed before.

This is because there are exact and approximate ways of calculating CSL (cycle service level). The former are difficult to calculate (and not typically used in business), and the latter tend to neglect the deviations in the reorder point (also called undershoots) this results in differences mentioned above. This paper presents an structured review of the literature on the methodology to be followed in the design of inventory management policy (s,Q) when demand process is stationary with discrete probability function, independent and identically distributed, and replenishment period L constant and pinpoints the most significant research gaps and also proposes guidelines for the practical application of the most usual approximations. Models are considered for lost sales and backorders.
