模糊聚类分析在配送中心订货策略中的应用

针对传统ABC分类方法的局限性,提出了面向订货策略的物料模糊聚类分析方法,以物料订货量和物料单价作为聚类指标,对物料进行模糊聚类分析,对于不同类别的物料实施不同的订货策略。给出了一个模糊聚类应用于订货策略的实例,并与基于ABC分类的库存控制系统进行了对比,表明基于多因素模糊聚类的库存控制系统能有效降低库存成本。

Adoption of improved irrigation and drainage reduction technologies under limiting environmental conditions

Modern irrigation technologies have been suggested as a means of conserving scarce water and reducing environmental pollution caused by irrigated agriculture. This paper applies an economic model of technology selection that provides a general framework to analyzing adoption of irrigation technologies under various environmental conditions. Data from the San Joaquin Valley of California is used to verify the theoretical relationships. Results suggest key variables to be considered by policy makers concerned with adoption of modern irrigation technologies. Among these variables are crop prices, water technology costs, farm organization characteristics, and the environmental conditions of the farm or the field. Policy implications were discussed and analyzed.This research was conducted while the first author was a visiting scholar with the Dept. of Agricultural Economics, University of California, Davis, and USDA-ERS, USA.

An efficiency analysis of Swedish employment offices

In this paper the method–production frontier analysis is used to analyse differences in efficiency between different Swedish Employment Offices. Earlier empirical labour market policy evaluation studies have utilised various measures that, however, do not take into consideration differences between organisation units. The main result of this investigation is that employment offices show major differences in the efficiency with which they carry out their job matching services.     

Climate Change Taxes and Energy Efficiency in Japan

In 2003 Japan proposed a Climate Change Tax to reduce its CO₂ emissions to the level required by the Kyoto Protocol. If implemented, the tax would be levied on fossil fuel use and the revenue distributed to encourage the purchase of energy efficient equipment. Analysis using the MIT Emissions Prediction and Policy Analysis (EPPA) model shows that this policy is unlikely to bring Japan into compliance with its Kyoto target unless the subsidy encourages improvement in energy intensity well beyond Japan’s recent historical experience. Similar demand-management programs in the US, where there has been extensive experience, have not been nearly as effective as they would need to be to achieve energy efficiency goals of the proposal. The Tax proposal also calls for limits on international emission trading. We find that this limit substantially affects costs of compliance. The welfare loss with full emissions trading is 1/6 that when Japan meets its target though domestic actions only, the carbon price is lower, and there is a smaller loss of energy-intensive exports. Japan can achieve substantial savings from emissions trading even under cases where, for example, the full amount of the Russian allowance is not available in international markets.
