温馨提醒:PIM-DEAsoft原厂已终场销售本款软件。建议您选用其他具备一样分析职能的代替产品,以便顺利推动科研工作。
?
DEA(Data Envelopment Analysis)是一种基于数学规划的步骤,用于丈量使用多个输入以确保多个输出的运作单元的效能和出产率。通常输入和输出是不相称的。
?
它起头由Charnes, Cooper, Rhodes (1978) 为规模报答不变 (CRS) 技术开发,后出处Banker, Charnes, Cooper (1984) 扩大以涵盖可变规模报答 (VRS) 技术。自1978年以来,已经颁发了数以千计的文章、书籍和论文,DEA模型迅速扩大到涵盖规模收益不变或不变、虚构或分类变量、自由裁量和非自由裁量变量、归并价值判断、纵向分析、随机DEA、Malmquist出产力变动指数和很多其他主题。
?
DEA已被用于各类情况。例如,它已被用于评估和比力教育部门(学堂、学院和大学)、卫生单元(医院、诊所)、农业出产单元(农。⒁幼⒒疃印⑹谐∽暄幼⒔煌ǎü肥鼗ぁ⒓,铁路),法院,以及其他利用。

【英文介绍】
?
DEA (Data Envelopment Analysis) is a mathematical programming based method to measure empirically the efficiency and productivity of operating units using multiple inputs to secure multiple outputs. Typically the inputs and the output are incommensurate. ?
?
It was originally developed by Charnes, Cooper, Rhodes (1978) for constant returns to scale (CRS) technologies and was extended later by Banker, Charnes, Cooper(1984) to cover variable returns to scale (VRS) technologies. Since 1978 thousands of articles, books and dissertations have been published and DEA models have rapidly been extended to cover non increasing or non decreasing returns to scale, dummy or categorical variables, discretionary and non-discretionary variables, incorporating value judgments, longitudinal analysis, stochastic DEA, Malmquist indices of productivity chnage,and many other topics. ?
?
DEA has been used in a variety of contexts. For example it has been used to evaluate and compare educational departments (schools, colleges and universities), health care units (hospitals, clinics) prisons, agricultural production units (farms), banks, sports teams, market research, transportation (highway maintenance, groups, railways), courts, among other applications.
