(1985)
Report de recerca
Accés obertDurante los últimos años ha decaído el huso de los modelos matemáticos de la Investigación Operativa, frente a este hecho este trabajo intenta analizar algunas de las posibles causas y de las posibles líneas de actuación ... -
A branch and bound approach for the capacitated plant location problem using cuts from the partial convex hull
(1984)
Report de recerca
Accés obertThe efficient solution of capacitated plant location problems usually requires the development of specific software mainly when the problems are pure integer ones, standard mathematical programming codes being highly ... -
An improved heuristic for capacitated location problems: some theoretical considerations about its performance
(1984)
Report de recerca
Accés obertThis paper describes a dual greedy heuristic for capacitated plant location problems and studies its computational behaviour. The good computational results obtained are explained from a theoretical viewpoint by means of ... -

Accés obertEl problema de decidir las ubicaciones de un máximo de K plantas, (almacenes, centros de distribución, etc.) dado un conjunto de J, [J]>K, emplazamientos posibles, para satisfacer las demandas de un conjunto I de centros ... -
Complementary remarks and improvements to a lagrangean heuristic for capacitated plant location problems
(1985)
Report de recerca
Accés obertIn a former paper, [1], a heuristic using multipliers from a langrean relaxation was proposed for getting feasible solutions to a class of pure integer capacited plant location problems. The heuristic consisted of three ... -
Computational experiments with location problems using automatic constraint generation
(1985-06)
Report de recerca
Accés obertWe report computational experience with the use of automatic constraint generation in the case of capacited location problems involving between 10 and 30 plants and up to 50 demand centers. For different types of model ... -

Kopernik : modeling business processes for digital customers
(2016-07-31)
Report de recerca
Accés obertThis paper presents the Kopernik methodology for modeling business processes for digital customers. These processes require a high degree of flexibility in the execution of their tasks or actions. We achieve this by using ... -
SHERPA: Towards a methodological acqusition of ERP solutions
(1998-12)
Report de recerca
Accés obertIn the IS area, methods have been focused mostly on IS development and less on its acquisition. In this last issue, we can find simple methods which give generic advises or series of steps on the acquisition of software, ... -
