PIM DEAsoft
|
- 数据包络分析软件
|

近年来已经有很多使用数据包络分析(Data Envelopment Analysis, DEA)来评估许多不同种类实体效益的多种应用,在很多不同背景的国家中从事不同的活动。一个原因是,因为经常有未知的复杂因素,很多动作牵扯到多次输入和输出之间的关系,DEA已经提供对解决这些情况的可能性。例子包括：在不同的地理位置美国空军基地的维护活动,或在英国和韦尔斯警察的火力分配,塞浦路斯和加拿大银行各分部的收益,美国、英国和法国的大学展现他们的教育和研究过程中的效率。借着各式各样的输入和输出：包括"社会上"和"安全网"的支出当作输入数据,和各种"生活质量"的尺寸当做输出的数据,这些种类的应用可以评价城市、地区和国家的效益。

而 PIM DEAsoft 正是 DEA 软件里面的佼佼者,因为它的两大优点：
- 拥有最大量、最新,并且正在不断扩展的 DEA 模型库；
- 处理数据集的限制只受你电脑能力的制约。

使用 PIM DEAsoft，你可以：- Assess units under constant or variable returns to scale;
- Assess units under non-increasing or non-decreasing returns to scale;
- Assess units under restrictions on the input/ output weights;
- Assess units under restrictions on the product of input/ output weights and corresponding
- input/output level, the restriction applying either only to the unit assessed or to all units;
- Estimate performance targets with varying priorities over the improvement of inputs/outputs;
- Assess units when some variables are exogenously fixed and returns to scale are variable;
- Assess the super efficiency of units, including automated identification of units above a user-specified threshold, removal and re-assessment of the remaining units;
- Identify whether increasing, constant or decreasing returns to scale hold locally for units efficient under variable returns to scale;
- Compute Malmquist productivity indices and their decomposition into boundary shift and efficiency catch-up.
- Compute cross-efficiency matrices using optimal weights of selected units to compute the efficiencies of other selected units;
- Use of categorical variables to select subsets of units to be assessed by a given DEA model in batch mode;
- Multiple DEA models can be set up, involving different input/outputs from a global data set to be executed in batch mode.
- and much more....
你还可以利用 PIM DEAsoft 生成一系列的结果：- Tables of efficiencies;
- Tables of Pareto efficient input-output levels for units;
- Tables of efficient peer units for each inefficient unit;
- Tables of input/output weights;
- Summary statistics (mean, variance, max, min etc) of efficiencies;
所有报告都可以：- Placed directly in "Excel" or in tab delimited text files;
- Can be sorted alpha-numerically;
- Can be for a selected unit or for all units.
