A Dea-based Malmquist Productivity Index Approach in Assessing Road Safety Performance
نویسندگان
چکیده
The data envelopment analysis (DEA) based Malmquist productivity index measures the productivity change over time. It can be further decomposed into two components: the change in efficiency and the technical change. In this study, a specific road safety outputoriented DEA-based Malmquist productivity index is introduced to assess the changes in road safety performance of 26 EU countries from 2000 to 2007. The results show a considerable road safety progress in most of the member states during this period. The decomposition into the two components further reveals that the bulk of the improvement was attained through the adoption of new road safety technologies or strategies, i.e., the technical change, rather than through the relatively inefficient countries catching up with those efficient ones, known as the efficiency change.

To evaluate the road safety development of a country over time, the percentage change in the number of road fatalities is traditionally the main indicator. However, simply considering the reduction in the road fatalities may not correctly reflect the real improvement in road safety because the transport circumstances of a country underlying the road fatalities also change every year. In this st...

This paper presents a data envelopment analysis (DEA) model combined with Bootstrapping to assess performance of one of the Data mining Algorithms. We applied a two-step process for performance productivity analysis of insurance branches within a case study. First, using a DEA model, the study analyzes the productivity of eighteen decision-making units (DMUs). Using a Malmquist index, DEA deter...

Moreover, the performance measurement should be accomplished in a multi-period h...
متن کاملDetermining Malmquist Productivity Index in DEA and DEA-R based on Value Efficiency
Malmquist Productivity Index (MPI) is a numeric index that is of great importance in measuring productivity and its changes. In recent years, tools like DEA have been utilized for determining MPI. In the present paper, some models are recommended for calculating MPI when there are just ratio data available. Then, using DEA and DEA-R, some models are proposed under the constant returns to scale ...
متن کاملThe interval Malmquist productivity index in DEA
One of the most popular approaches to measuring productivity changes is based on using Malmquist productivity indexes. In this paper we propose a method for obtaining interval Malmquist productivity index (IMPI). The classical DEA models have been before used for measuring the Malmquist productivity index. The current article extends DEA models for measuring the interval Malmquist productivity ...
