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. ...doi:10.1007/bf01580875 fatcat:3jtclwmntzgjxkqs5uecombdaa
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. ...doi:10.1016/j.ejor.2012.08.016 fatcat:c27kagfnxnhjfbil2rydhjhomm

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  . ...doi:10.1007/0-387-23081-5_20 fatcat:sjz6ffii5zar5b6gs4cloec33i
