Customer Service Satisfaction Evaluation System and Method Viewed From Supply Chain Management

Based on experience in customer service evaluation,through the analysis of many factors affecting customer satisfaction calculation estimate, customer service evaluation rules as well as customer-oriented and supply chain partner-oriented methods are developed and discussed from the view of supply chain, besides, we construct two sets of customer satisfaction evaluation systems, in which we perform non-dimensional analysis on evaluation system to form single factor evaluation matrix after using improved AHP to determine each factor item's weighting ,utilizing fuzzy decision theory to construct evaluation model for integrated estimate. This evaluation method is scientific, round and objective with more stability and convienience in practical use.     

Determination and Evaluation of Saccharides Content in Extract of Herba Spirodelae Seu Lemnae Polysaccharides

In the course of searching immunodulators from natural herbal sources,the polysaccharide has been isolated from the water extract of duckweed(Herba Spirodelae seu Lemnae).The authors aim at investigating the methods that determine the content of total saccharides in the mixture,accordingly,to be used as a quality control in the procedure of producing polysaccharides from duckweed.The contents of saccharides in the extraction were mensurated by spertrophotometry of sulphuric acid-phenol and sulphuric acid-anthrone.And the validitiy of methods was evaluated through some indexes such as linearity and range,precision,stability,and accuracy.The results reveal the methods are convenient,rapid,accurate,and high sensitive,thereby leading to a wide and effective use in determining the saccharides contents in polysaccharides extraction from Herba Spirodelae seu Lemnae.

A MATHEMATICAL MODEL OF FUZZY EVALUATION METHOD FOR ENVIRONMENTAL POLLUTION

The problem of fuzzy evaluation of environmental pollution is importantboth in environment science and in environmental protection.Usual evaluationmethods have their own characteristics.This paper puts forward a mathematicalmodel of fuzzy evaluation method in grades by means of systematic analysisfor environmental pollution.At the same time,it assigns weighted values byordering based on paired comparison.     

南方涝渍地综合整治开发效果的评价研究

以 2个示范区作为实例构建了一套对南方涝渍地实施以农业工程技术为基础的综合整治与建设后的效果进行评价的评价体系。该体系由工程效果、农业综合开发效果和综合效益等 3部分构成。在工程效果评价中 ,重点对工程实施后的抗灾减灾效果和代表经过改良后农田物理构架改变的“农田综合生产力指数 (IPI)”等二方面进行了分析。研究表明 ,该评价体系能比较全面、有重点地对涝渍地综合改良的实效做出评价。由于该体系实现了评价的数量化 ,使用该评价体系既利于对同一地区改良前后的效果做出对比分析、找出存在的问题 ,也利于对邻近不同地区的改良效果做出比较评价。对 2个示范区进行实际评价的结果表明 ,该地区的涝渍地综合整治开发效果良好 ,其第一期工程取得成功。     

An approach to multi-criterion evaluation of irrigation system performance

Irrigation systems aim to meet multiple objectives and performance must therefore be assessed using quantifiable measures for each. It therefore becomes an extremely difficult task to capture the valuation of all of them simultaneously and to mentally process the trade-offs between them in order to arrive at an overall impression of system performance. There is a need for a methodology which provides a systematic approach to comparing and combining the components of overall performance.Multi-Attribute Utility Theory offers an attractive approach to assessing performance of irrigation systems in the form of a utility function which reflects the strength of preferences and trade-offs between individual performance criteria. The method is described and demonstrated on the basis of a case study of irrigation in Sudan.     

An economist's perspective on irrigation performance assessment: With examples from large scale irrigation in Morocco

This paper accepts that assessing the performance of irrigated agriculture is difficult because being multi-dimensional it requires a multi-disciplinary approach. Public irrigation schemes may have a number of often competing objectives and are assessed by interest groups with differing values and perspectives. A wide range of performance indicators are thus required. Some of these and the complex inter-relationships that may exist in the system are illustrated.     

Modernization of furrow irrigation in the South-East of France automation at field level and its implications

Surface irrigation rehabilitation in the South-East of France has shown success ever since the beginning of its development in the early 1980s. The gradual introduction of surface distributors, mechanized or automated has resulted in water savings and above all in decreased labor input. The distributors used are: gated pipes, layflat tubing, buried low pressure pipe and cablegation. They are used over an ever increasing area which attained about 1000 ha in 1987.Improvement is made in furrow head distribution as well as in field levelling, furrow flow evaluation, flow control at the head of the furrow and in the collective system.The effect of a modernized system and improved knowledge has been to make automated surface irrigation (particularly furrow irrigation) a modern application method in competition with techniques such as sprinklers and localized irrigation.Abbreviations ASAE American Society of Agricultural Engineers - CEMAGREF Centre d'Etude du Machinisme Agricole du Génie Rural des Eaux et des Forêts, Division Irrigation, BP 5095, 34033 Montpellier et BP 31 Le Tholonet 13612 AIX - ENGREF Ecole Nationale du Génie Rural des Eaux et des Forêts, Département Maîtrise de l'Eau et Développement, BP 5093, 34033 Montpellier - IRAT Institute de Recherche en Agronomie Tropicale, Zolad Mini Parc Bt7, 34100 Montpellier - P.V.C.
