Performance evaluation of Uttarakhand electric utility data using slack based measure and Two-stage DEA modelling

TL;DR: In this article, the performance of 23 Electrical Distribution Divisions (EDD's) of an Indian state, Uttarakhand for the period of 2005-2006 using the concepts of additive model (AM), Slack Based Modelling (SBM), and Two-stage Data Envelopment Analysis (DEA).
Abstract: This study reports the performance of 23 Electrical Distribution Divisions (EDD's) of an Indian state, Uttarakhand for the period of 2005–2006 using the concepts of Additive Model (AM), Slack Based Modelling (SBM) and Two-stage Data Envelopment Analysis (DEA). Slack Based Modelling helps in quantifying the slacks, which is a hidden source of inefficiency that might be present in BCC efficient DMU's. Following the slack quantification, a two-stage DEA is applied. The results obtained from AM and SBM indicate that numerous EDD's have scope for improvement in overall efficiency by incorporating the slacks that have been identified in the particular EDD. Further the two stage DEA modelling suggest that the inefficiency is primarily due to the intermediate measures.

TL;DR: In this paper, the authors used DEA-SBM to obtain the target variables and the decision tree model to produce important indicators to promote Taiwan's development in all aspects by improving social, economic, and environmental efficiency, while ensuring the sustainable development of environmental protection.
Abstract: This study uses DEA-SBM to obtain the target variables and the decision tree model to produce important indicators. The government can promote Taiwan's development in all aspects by improving social, economic, and environmental efficiency, while ensuring the sustainable development of environmental protection. The 15 social, economic, and environmental variables are used in the decision tree to obtain 3 repeatable important indicators that can affect Taiwan's social change, economic development, operational capability, environmental pollution, and change. K-means divides the 22 counties and cities into 1 capital city, 5 municipalities, and 16 other counties and cities, in order to understand the influence of the economy on social and environmental development during the period of 2013-2015 in Taiwan.

TL;DR: A nonlinear (nonconvex) programming model provides a new definition of efficiency for use in evaluating activities of not-for-profit entities participating in public programs and methods for objectively determining weights by reference to the observational data for the multiple outputs and multiple inputs that characterize such programs.

TL;DR: This invention provides a Printing image area measuring device which can detect a printing image area with high accuracy even if the surface of a printing plate is uneven, which device is simple in construction, low in manufacturing cost and high in measurement accuracy.
Abstract: A system in which data for controlling amounts of ink for a number of printing machines, having a variety of printing plates, are measured with one measuring device. This invention provides a printing image area measuring device which can detect a printing image area with high accuracy even if the surface of a printing plate is uneven, which device is simple in construction, low in manufacturing cost and high in measurement accuracy, and which can provide in-line automatic measurement in a printing line.

TL;DR: In this article, the authors use DEA to model DMUs that produce in two stages, with output from the first stage becoming input to the second stage, and apply the model to Major League Baseball, demonstrating its advantages over a standard DEA model.
Abstract: We show how to use DEA to model DMUs that produce in two stages, with output from the first stage becoming input to the second stage. Our model allows for any orientation or scale assumption. We apply the model to Major League Baseball, demonstrating its advantages over a standard DEA model. Our model detects inefficiencies that standard DEA models miss, and it can allow for resource consumption that the standard DEA model counts towards inefficiency. Additionally, our model distinguishes inefficiency in the first stage from that in the second stage, allowing managers to target inefficient stages of the production process.
