In manual order picking systems, order pickers walk or drive through a distribution warehouse in order to collect items which are requested by (internal or external) customers. In order to perform these operations efficiently, it is usually required that customer orders are combined into (more...

The most recent optimization algorithm for (s, S) order policies with continuous demand was developed byFedergruen and Zipkin (1985). This was also the first efficient algorithm, which uses policy iteration instead ofdiscretization. Zheng and Federgruen (1991) developed an even more efficient...

This paper extends a fundamental result about single-item inventory systems. This approachallows more general performance measures, demand processes and order policies, and leads toeasier analysis and implementation, than prior research. We obtain closed form expressions forthe Laplace...

In equipment-intensive industries such as truck manufacturing, electronics manufacturing, photo copiers,and airliners, service parts are often slow moving items for which, in some cases, the transshipment timeis not negligible. However, this aspect is hardly considered in the existing spare...

In this paper we first show that the gains achievable by integrating pricing and inventory control are usually small for classical demand functions. We then introduce reference price models and demonstrate that for this class of demand functions the benefits of integration with inventory control...

This article studies specific aspects of the joint replenishment problem in a realsupply chain setting. Particularly we analyze the effect on inventory performance of havingminimum order quantities for the different products in the joint order, given a complextransportation cost structure. The...

The pressure on companies towards sustainable development is changing the way they are dealing with their supply chain network. Practices are not limited to the company level. They are involving suppliers, customers, government, society and other stakeholders that impact and are impacted by the...

This publication presents a methodology for planning sustainable supply chain initiatives, consisting of three scopes, each with its appropriate mechanism and background theory. The first one 'Acting In' structures organizational practices in a 'Framework for Managing Sustainable Supply Chain...

The EU Directive on Corporate Sustainable Due Diligence has sparked fierce debate about the regulation of supply chains. The directive's objectives are aligned with European values. However, it raises concerns that the compliance costs of social and environmental regulations may be privatised in...

Ein Risiko der aktuellen Wirtschaftskrise ist, dass partnerschaftliche Beziehungen zwischen Herstellern und Zulieferern auf der Strecke bleiben. Überwiegend erhielten deutsche Automobilhersteller bisher nur befriedigende Bewertungen bei ihren Zulieferbeziehungen. Demgegenüber gilt das...
