14th International Symposium on Mathematical Programming

1990 Mathematical programming  
A v ariation of bundle methods is presented by means of which such a t ype of problems can be solved.In this variation a dynamic polyhedral model of dom is generated by means of normal vectors.In addition  ...  to the well known serious steps und null steps of bundle methods a third type of steps is used to generate the model of dom .  ...  The approach uses a linear description in a higher dimensional space of the convex hull of the disjunctive set created by imposing one or several 0-1 conditions.  ...

Berit D. Brouer, Jakob Dirksen, David Pisinger, Christian E.M. Plum, Bo Vaaben
2013 European Journal of Operational Research  
This article focuses on the formulation of a reliable measure of profitability for the involved vehicles. The measure is based on a timespatial decomposition of customer data.  ...  The problem was formulated for the real packing constrains appearing in the sales and logistics departments of household equipment factory.  ...  We give a disjunctive graph formulation and use the job insertion (sub-) problem as a mechanism for local search. Computational results support the value of the approach.  ...

Multicriteria Decision Aid/Analysis in Finance [chapter]

Jaap Spronk, Ralph E. Steuer, Constantin Zopounidis
International Series in Operations Research & Management Science  
Multicriteria decision aid (MCDA), an advanced branch of operations research, provides financial decision makers and analysts with a wide range of methodologies wellsuited for the complexity of modern  ...  The aim of this chapter is to provide an in-depth presentation of the contributions of MCDA in finance focusing on the methods used, applications, computation, and directions for future research.  ...  The latter calls for a sophisticated performance evaluation process that explicitly acknowledges the role of learning. 2. This section draws heavily on a part of Hallerbach & Spronk [66] .  ...
