Abstract:

Data Envelopment Analysis (DEA) is a non-parametric approach to measuring efficiency. It is increasingly utilised in areas such as finance, education and healthcare. As with many modelling techniques, DEA is based on and restricted by certain assumptions. One of these is the assumption of homogeneity, which asserts that all decision making units must have the same inputs and outputs. Previously, research has had to develop ad hoc methods to cope with this issue, such as removing non-homogenous units, removing key inputs and outputs, having to run multiple DEA models, and using other methods su

Abstract:

The ability to anticipate future capabilities of technology products has broad implications for organizations. Technological forecasting allows management to improve resource allocation, make better staffing decisions, and more confidently plan facilities and capital expenditures. Technology forecasting may also identify potential new markets and opportunities, such as finding ways to exploit current technology beyond its originally intended purposes. Modern technology forecasters use an array of forecasting methods to predict the future performance of a technology, such as time-series analysi

Abstract:

Data Envelopment Analysis (DEA) is a linear programming technique for measuring the relative efficiencies of a set of Decision Making Units (DMUs). Each DMU uses the same set of inputs in differing amounts to produce the same set of outputs in differing quantities. Weights are freely allocated in order to allow these multiple incommensurate inputs and outputs to be reduced to a single measure of input and a single measure of output. A relative efficiency score of a DMU under Constant Returns to Scale is given by maximising the sum of its weighted outputs to the sum of its weighted inputs, such

We develop approaches that aim to capture the time lag between the outputs and the inputs in assigning the efficiency values to DMUs.

(Chambers 1988) A researcher that wants to estimate this elasticity, or some other comparative static, typically would do so using parametric production or cost function (e.g. translog or normalized quadratic) with panel data. For a study with only cross-sectional data, the construction of such a function may be problematic.

Abstract:

碩士<br>國立交通大學<br>工業工程與管理系<br>91<br>The computational power of mathematical programming has increased enormously over the last two decades. Obviously, this is partly due to hardware improvements, but in large part it is also due to algorithmic. It‘s easy to implement complicated programs. Since Simplex discovered in 1947, the field of linear programming, together with its extensions has grown by leaps and bounds and is today the most widely used tool. In 1978, Data envelopment analysis (DEA) was first introduced in the literature. Up to the present, its one popular optimization method of mathema

Abstract:

Critically ill patients suffering from either closed head trauma or septic shock were studied retrospectively to see if the mathematical programming technique of Data Envelopment Analysis (DEA) could be used to develop models to assess an individual patient's progress in an Intensive Care Unit (ICU). Unlike current logistic regression models that focus on the mean values for groups of patients, the DEA models evaluate each patient individually by calculating an “efficiency” score based on a patient's ability to maximize output for a given set of physiologic inputs. Patients with high efficienc

Abstract:

碩士<br>國立暨南國際大學<br>資訊管理學系<br>99<br>Data envelopment analysis (DEA) is a commonly used assessment method that is used to measure the performance of decision-making units (DMUs), while mainly dealing with precise input values and precise output value data. However, they are limited to measuring the efficiency of each DMU one by one. In other words, each DMU can find the best weight for itself but cannot directly sort them. Therefore, none of the DMUs can be compared directly because of a different basis. This paper proposes a new DEA model to handle imprecise and negative

Abstract:

博士<br>國立臺灣科技大學<br>企業管理系<br>100<br>Despite the wide use of the directional distance function, the evaluation of environmental and technical efficiencies using this function does not consider the possible technology heterogeneity among different decision making units (DMUs). Evaluations usually assume that the DMUs are equipped with similar levels of technology. Therefore, the present study applies the metafrontier concept to the one-stage and two-stage evaluation process for estimating the efficiency of data envelopment analysis gauges a metafrontier using overall samples, divides the DMUs, and
