Chen, Zhi-Long; Hall, Nicholas G. - In: Manufacturing & Service Operations Management 10 (2008) 1, pp. 84-107

The classical scheduling literature considers many problems where a given set of jobs must be processed at minimum cost, subject to various resource constraints. The literature only considers the issue of revenue generation in a very limited way, by allowing a job to remain unprocessed and its...

On the development of improved adaptive models for efficient prediction of stock indices using clonal-PSO (CPSO) and PSO techniques

Majhi, Ritanjali; Panda, Ganapati; Sahoo, Gadadhar; … - In: International Journal of Business Forecasting and … 1 (2008) 1, pp. 50-67

The present paper introduces a new clonal particle swarm optimisation (CPSO) and PSO techniques to develop efficient adaptive forecasting models for short and long-term prediction of S&P 500 and DJIA stock indices. The basic structure of the models is an adaptive linear combiner whose weights...

Heuristic approaches for determining minimum cost delivery quantities in supply chains

Hornung, Alexander; Monch, Lars - In: European Journal of Industrial Engineering 2 (2008) 4, pp. 377-400

In this paper, we consider heuristic approaches for the determination of delivery quantities in a Supply Chain (SC). The problem under consideration is important for the design of delivery quantity negotiations between manufacturers and suppliers. We describe a Mixed Integer Programming (MIP)...

Mathematical model and genetic algorithm for distribution logistics problem with maximum route length

Sivakumar, P.; Ganesh, K.; Arunachalam, S. - In: International Journal of Logistics Economics and … 1 (2008) 3/4, pp. 307-329

Logistics is no longer seen as tactical and cost-driven – it is strategic. Considering the driver-on-time rules and with the perishable nature of the products, the travel length/time is one of the critical constraints in distribution logistics. We consider a typical logistics problem with...

Approximation algorithms for a vehicle routing problem

Krumke, Sven; Saliba, Sleman; Vredeveld, Tjark; … - In: Computational Statistics 68 (2008) 2, pp. 333-359

In this paper we investigate a vehicle routing problem motivated by a real-world application in cooperation with the German Automobile Association (ADAC). The general task is to assign service requests to service units and to plan tours for the units such as to minimize the overall cost. The...
