Software to display DNA sequences is a crucial tool for bioinformatics research. This study examined techniques for navigating large DNA sequences via panning and zooming. This involved surveying the navigation facilities of current bioinformatics applications and performing a heuristic analysis on the most common interface controls found. Several(More)
Integration has been one of the dominant themes in the development of logistics management. This development began around 40 years ago with the integration at a local level of transport and warehousing operations into physical distribution systems. Today, many businesses are endeavoring to integrate supply networks that traverse the globe, comprise several(More)
Information visualization can play an important role for exploring model sensitivity to facilitate decision making under uncertainty. It provides a means for graphically exploring the relationships between the output and the inputs of a model and to determine how “sensitive” a model is to changes in the values of the input. The literature shows how(More)
Informed decisions are based on the availability of information and the ability of decision-makers to manipulate this information. More often than not, the decision-relevant information is subject to uncertainty arising from different sources. Consequently, decisions involve an undeniable amount of risk. An effective visualisation tool to support informed(More)
Recent research has updated a 1998 study of the effects of traffic congestion on logistical efficiency in the UK. It has focused on the contribution of congestion to unreliability across nine sectors. The relationship between traffic flow and transit time variability has been modeled using data from the Highways Agency and speed-flow ratios. An analysis of(More)
Introduction The last link in the supply chain (from retailer / supplier to consumer), the so called “last mile”, is not only the most visible, but can also be the most energy intensive part of the supply chain. Several authors (Browne et al. 2008; Weber et al. 2008; Jespersen, 2004) note that in the case of conventional shopping, personal shopping trips(More)
