The specific objective is to reduce the time in the system of the patients. The resulting simulator should represent all the laboratories of the company and use an electronic sheet as an interface for the parameters. To build the model, the exams were grouped in different families and the process times and resources demanded were studied fur each one of these families. The model was validated by experts and implemented with ARENA and EXCEL. Different configurations of resources were studied to detect bottlenecks, which allowed us to reallocate personnel to peak hours, to redesign facilities and to reduce the waiting time of the patients.

Through the use of utility functions, this decision criterion models a decision maker's preferences for sequences of wealth positions generated by a set of investment opportunities relative to targeted wealth positions developed by the firm. The derivation of this criterion is related to cash flow analysis and the use

El modelo resulta de particular interés y aplicación en la industria del mueble, por la gran diversidad de productos, procesos y equipos involucrados en la fabricación de muebles. El Sistema ABC utiliza un procedimiento de asignación, donde los recursos son primero asignados a las actividades y luego éstas son asignadas a los productos o objetos de costo, mediante los llamados generadores o inductores de costos. Este sistema permite la asignación y distribución de los diferentes costos indirectos de acuerdo a las actividades realizadas, identificando el origen del costo de la actividad, no sólo para la etapa de producción sino también para la distribución y venta. Para ilustrar el uso del modelo, éste se aplica a la determinación del costo de producción de dos sillas mecedoras del tipo deslizantes. Se concluye que los costos totales de fabricación son subvaluados por el método tradicional respecto del método ABC, en un 19,8% para el modelo Pelequén y en un 29,3% modelo Moderno.
