The Malmquist Productivity Index (MPI) suggests a convenient way of measuring the productivity change of a given unit between two consequent time periods. Until now, only a static approach for analyzing the MPI was available in the literature. However, this hides a potentially valuable information given by the evolution of productivity over time. In this paper, we introduce a dynamic procedure ...

This paper presents a novel control strategy for transferring large inertia loads using flexible space manipulators in orbit. The proposed employs Luenberger state observer and damping-stiffness controller to address issues of tracking error vibration. A comprehensive joint dynamics model is developed identify the main sources disturbance, designed estimate unmeasurable transmission deformation...

This study evaluated the productivity of non-profit hospitals in the USA in applying DEA-base Malmquist productivity Change index, decomposed into technical efficiency change index and technical progressive change index. Data used for this analysis consisted of 118 non-profit hospital utilization data and financial statements from 1993 through 2003. DEA-based Malmquist was conducted to measure ...

This paper analyses hospital performance using Data Envelopment Analysis (DEA) and the Malmquist productivity index. We follow two approaches to quantify movements in productivity: (1) the traditional approach that only considers output and input variables; and (2) a more comprehensive approach that incorporates movements in quality and restricts some achievements, if quality is reduced. On the...

Productivity growth and efficiency improvements are the major sources of economic development. Pure efficiency, scale efficiency, and technology are basic factors, and rules and regulations and balance are recently known factors affecting the Malmquist productivity index. The index is the most common productivity growth index that uses data envelopment analysis models over multiple time periods...

The normal form derived by Mansour [I] for single-input / single-output, time-invariant, linear discrete systems will be extended to the multivariable case. An algorithm will be used to achieve simple computation of this form starting with the Luenberger first canonical form. The construction of this form will be illustrated by examples applied to model reduction of multivariable discrete-time ...
