计算机广域网在物流系统的信息交换方式

计算机局域网和广域网在物流交换系统中得到广泛应用。广域网在信息交换方式上可分为三种模型,即直接信息交换模型,索取信息交换模型和网站平台信息交换模型。这三种模型在信息交换方式上各有优劣,它们适用的规模和范围也各有差异。制造业物流、商业流通物流和第三方物流企业在选择信息交换方式上应根据本企业自身的物流业务类型、特点、规模、经济实力情况,选择更适合、更合理的信息交换方式。

Impacts of considering climate variability on investment decisions in Ethiopia

Extreme interannual variability of precipitation within Ethiopia is not uncommon, inducing droughts or floods and often creating serious repercussions on agricultural and nonagricultural commodities. A dynamic climate module is integrated into an economy‐wide model containing a detailed zonal level agricultural structure. This coupled climate‐economic model is used to evaluate the effects of climate variability on prospective irrigation and infrastructure investment strategies, and the ensuing country‐wide economy. The linkages between the dynamic climate module and the economic model are created by the introduction of a climate‐yield factor (CYF), defined at the crop level and varied across Ethiopian zones. Nine sets of variable climate (VC) data are processed by the coupled model, generating stochastic wet and dry shocks, producing an ensemble of potential economic prediction indicators. Analysis of gross domestic product and poverty rate reveal a significant overestimation of the country's future welfare under all investment strategies when climate variability is ignored. The coupled model ensemble is further utilized for risk assessment to guide Ethiopian policy and planning.

Relationship Marketing and its Synergy with Web-based Technologies

This paper examines the distinctives of relationship marketing, provides a simple taxonomy of the world wide web, and proposes that there is a high level of synergy between the inherent functionality and interactivity provided by the world wide web and the implementation of a relationship marketing perspective. This proposition is tested using data from a national survey of New Zealand organizations known to maintain and operate a web site, and the relationship is found to be significant. It is concluded that the inherent nature of emerging Internet technologies is supportive of the higher levels of customer interaction implicit in relationship marketing.
