We test the lower bound for a static remanufacturing system with returns proposed by Feng and Viswanathan (2014) against two heuristics proposed by Choi et al. (2007) and Schulz and Voigt (2014). A numerical study with 81,000 instances concludes that the lower bound always holds for the Choi...

The efficient supply of spare parts is of prime concern for OEMs. Next to the traditional spare parts sources in form of final order and remanufacturing, the option to buy back broken products prevents the OEM from fulfilling his spare parts availability obligation in the end-of-life phase and...

Mit dem von P. Nyhuis und H.-P. Wiendahl entwickelten Konzept der logistischen Kennlinien ist das Ziel verbunden, den Zusammenhang zwischen verschiedenen Kenngrößen eines logistischen Systems mit einem einfachen Funktionsverlauf hinreichend genau abzubilden. Im Rahmen von Lagerkennlinien soll...

In the area of reverse logistics, remanufacturing has been proven to be a valu- able option for product recovery. In many industries, each step of the products’ recovery is carried out in lot sizes which leads to the assumption that for each of the different recovery steps some kind of fixed...

Using data of Swiss referenda from 1981 to 1999, this paper presents new empirical results which allow us to discriminate better between the decision and mobilisation hypotheses of electoral participation. First, theoretical considerations which lead to these hypotheses are presented as well as...

An increasing number of member countries of the European Union (EU) is heading for ratification through referendum of the yet to be adopted constitution for Europe. Such popular votes will add an additional ratification constraint and empirical models will require information on the positions of...

The term urban sprawl is often used to describe apparent inefficiencies of spatial development, including disproportionate growth of urban areas and excessive leapfrog development. In Switzerland, where open space is a scare resource, sprawl takes place all over the country. It goes at the...

In a recent contribution, Teunter et al. [2006. Dynamic lot sizing with product returns and remanufacturing. IJPR 44 (20), 4377-4400] adapted three well-known heuristic approaches for the single-item dynamic lot sizing problem to incorporate returning products that can be remanufactured. The...

Analyzing static lot sizing problems has always attracted a considerable interest in scientific literature. A commonly applied methodology to solve the trade-off between setup and holding costs is to order the Economic Order Quantity (EOQ) whenever the corresponding inventory is depleted. Yet,...
