1. Solver y Programación Lineal
Veremos ahora la utilización de Solver para resolver casos de Programación Lineal, aplicándolas a un ejemplo muy elemental, tomado del libro de Eppen, Gould y Schmidt, Investigación de Operaciones en la Ciencia Administrativa, 3ra edición, Editorial Prentice Hall. En éste y en otros libros de Investigación Operativa, se encontrarán numerosas aplicaciones de Programación Lineal y no Lineal. Nota Las inestabilidades (por malas soluciones iniciales) del algoritmo de optimización no lineal no se presentan en casos de Programación Lineal, dado que Solver utiliza el Método Simplex. El Modelo de la Protrac • La Protrac Inc., fabrica dos tipos de productos químicos, E y F, cuya utilidad neta es de $5000 y $4000 por tonelada respectivamente. • Ambos pasan por operaciones de 2 departamentos de producción, que tienen una disponibilidad limitada. • El departamento A dispone de 150 horas mensuales; cada tonelada de E utiliza 10 horas de este departamento, y cada tonelada de F, 15 horas. • El departamento B tiene una disponibilidad de 160 horas mensuales. Cada tonelada de E precisa de 20 horas, y cada tonelada de F precisa de 10 horas para su producción. • Para la producción global de E y F, se deberán utilizar al menos 135 horas de verificación en el próximo mes; el producto E precisa de 30 horas y F de 10 horas de verificación por tonelada. • La alta gerencia ha decretado que es necesario producir al menos una tonelada de F por cada 3 de

    Sensitivity Report A sensitivity report of the analysis described above was created and can be found in Appendix E. The solution is not degenerate because there are no zero values in the allowable increase or allowable decrease columns of the constraints in the Sensitivity Report. All of the constraints affect the optimal solution. The solution is unique because there are no zero values in the allowable increase or allowable decrease columns in the decision variables section of the Sensitivity Report. This shows that there are no other combinations of production levels that will optimize this solution.…

    The development of linear programming has been ranked among the most important scientific advances of the mid 20th century. Its impact since the 1950’s has been extraordinary. Today it is a standard tool used by some companies (around 56%) of even moderate size. Linear programming uses a mathematical model to describe the problem of concern. Linear programming involves the planning of activities to obtain an optimal result, i.e., a result that reaches the specified goal best (according to the mathematical model) among all feasible alternatives.…
