Resumen
This research proposes an application considered the systems approach of
the model inventory with a periodical review to the copper layers used to
produce transformers. The model was constructed under the inventory
regulations (R, S) whereas R means the years taken for supervision and S
means the inventory level both regulated by probabilistic demand (D)
considering the delivery period de time (L) already established.
In order to set the model, historical data of critical materials were used. To
have the demand distribution, Kolmogorov-Smirnov and two times Ji at 5% of
significance were tested and to decide which model was the best the AIC
criteria was applied.
Settling the model of periodical revision it is established the service level of
the inventory as well as its cost obtaining the lowest cost for a 90% level of
service.
