Zusammenfassung Die gebräuchlichen Methoden zur Verdeutlichung der konjunkturellen Aussage einer Zeitreihe liefern an ihrem aktuellen Rand nur ein relativ ungenaues Bild. Darum wird hier als ein alternatives Verfahren vorgeschlagen, das Signale einer sich anbahnenden konjunkturellen Wende in...

Zusammenfassung Es wird ein Tiefpaßfilter vorgestellt, der speziell dafür entworfen wurde, die konjunkturelle Entwicklung am aktuellen Rand einer Zeitreihe nachzuvollziehen. Anhand von Transferfunktionen, praktischen Anwendungen und stochastischen Simulationen werden seine Eigenschaften mit...

Zusammenfassung In der vorliegenden Arbeit wird die Leistungsfähigkeit zweier Verfahren zur Verdeutlichung der konjunkturellen Entwicklung einer wirtschaftlichen Zeitreihe am aktuellen Rand verglichen. Es handelt sich dabei um einen neu entwickelten Tiefpassfilter und das...

Summary The Baxter-King filter shows some weaknesses, particularly with regard to monthly time series. This procedure involves not only a loss of data for the border areas of time series, but suppresses inadequately high frequency components and shows as a low-pass filter only the performance of...

In the UK there have been some recent signs that the inland waterways can play a role in meeting the nation's transport needs. The author discusses the progress already made and what still needs to be done so that the country's canals can once again take up their position in the transport scene.

Britain's share of overseas trade would increase if more companies were to change to a door‐to‐door pricing system — a price inclusive of transportation. In a survey, tradition was given as the main reason for companies not using “delivered” pricing. It is argued that this system...

Purpose Following the methodology designed for selecting the best industrial and technological diversification strategy, one of the best methods for achieving the long-term sustainability of companies, the purpose of this paper is to describe its application in the service supply chains (SSCs)...

This paper describes the results of an effort to predict future freight volume in the truckload (TL) trucking industry. The approach involves the use of stepwise multiple linear regression models that relate freight volume to a variety of economic indicators. The models are built using a large...

The article reports the findings of research carried out by the authors into dedicated contract distribution (DCD), a service which is “tailor‐made” to the requirements of users. Major characteristics of the DCD marketplace in the UK are identified and future prospects for growth are...

The dynamic vehicle scheduling problem for a shipper involves managing transport of freight originating at various locations to minimise transport costs. The job involves dynamic assignment of vehicles contracted from carriers to loads available at multiple locations on a real time basis. A...
