Container storage and transshipment marine terminals

This study addresses the storage arrangement of transshipment containers on a container yard, in order to carry out efficiently the ship handling operations at a terminal where mega-containerships call. An optimization model is specified to investigate the flow of containers from the mega-containership to feeder ships using intermediate storage at the yard. A heuristic based on the lagrangian relaxation is formulated. The quality of the heuristic approach is tested in a number of experiments. In the experiments, various situations are analyzed with respect to mega-containership arrival rates, some strategies for stack arrangements and terminal layouts.     

Approaches towards a generic methodology for storage of hazardous energy carriers and waste products

Energy carriers – either conventional or ‘new’ ones – have to be provided in large amounts to meet the requirements of permanent availability and reliable supply of electricity. Depending on their state of aggregation, energy carriers are either stored in large masses (if solid or liquid) or at elevated pressures (if gaseous). Both impose the hazard of large-scale fire, in the latter case additionally the danger of explosion or unintended release. Very similar hazards occur for wastes. Solid wastes are present in large masses and only a small part is recycled. Most of the solid wastes are used in energy conversion. The main gaseous waste is CO₂. During capturing also the hazard of unintended release exists. In this article, existing approaches for safe storage and fire prevention are discussed and a generic methodology is outlined. This methodology consists of the following steps:

? gaining knowledge about the behaviour of the material stored (reactivity, thermal stability, etc.),

? assessing the environmental conditions for the storage site (neighbourhood, safety distances, etc.),

? assessment of prospective consequences of an incident and

? development of individual loss prevention conceptions.

All steps require both experimental testing and theoretical considerations about accident scenarios as integral parts of the methodology.

Cash Marketing Styles and Performance Persistence

Much agricultural economics research has been dedicated to determining the best time for producers to sell their commodities. Unlike this past research, we look at how producers actually sell commodities. The extent to which producers display an active or mechanical marketing style is measured using individual farmer sales. The activeness of a producer's marketing strategy is measured by how much the timing of their strategy varies from year to year. Results show no relationship between activeness and net prices received. Furthermore, the results show no evidence of performance persistence by individual producers.
