Optimization Heuristics for the Combinatorial Auction Problem

Schwind, Michael; Stockheim, Tim; Rothlauf, Franz - Betriebswirtschaftliches Institut <Mannheim>; … - 2003

This paper presents and compares three heuristics for the combinatorial auctionproblem. Besides a simple greedy (SG) mechanism, two metaheuristics, a simulatedannealing (SA), and a genetic algorithm (GA) approach are developedwhich use the combinatorial auction process to an allocation with...

Locating collection and delivery points using the p-median location problem

Tadić, Snežana; Krstić, Mladen; Stević, Željko; … - In: Logistics 7 (2023) 1, pp. 1-17

Background: Possible solutions to overcome the many challenges of home delivery are collection and delivery points (CDPs). In addition to commercial facilities, the role of CDPs can also be played by users' households, providing a crowd storage service. Key decisions regarding CDPs relate to...

Using recurrent neural networks for the performance analysis and optimization of stochastic milkrun-supplied flow lines

Südbeck, Insa; Mindlina, Julia; Schnabel, André; … - 2022

Long-term throughput, as a key performance indicator of a stochastic flow line, is affected by numerous parameters describing the features of the flow line, such as processing time and buffer size. Fast and accurate evaluation methods for a given set of values for those parameters are a...

Direct minimization of error rates in multivariate classification

Röhl, Michael C.; Weihs, Claus - 1999

We propose a computer intensive method for linear dimension reduction which minimizes the classification error directly. Simulated annealing (Bohachevsky et al 1986) as a modern optimization technique is used to solve this problem effectively. This approach easily allows to incorporate user...
