This research group, led by Professor of Statistics and Operations Research, Jesús T. Pastor, includes two additional mathematicians, José Luis Ruiz and Inmaculada Sirvent, and two statisticians, Juan Aparicio and Nuria Ramón. All group members are PhD's and belong to the UMH Center of Operations Research. The group grew out of a core of senior investigators formed by Jesús T. Pastor, José Luis Ruiz, and Inmaculada Sirvent, to which Juan Aparicio and Nuria Ramón subsequently joined as doctoral students.
Among the group's main objectives are the study and analysis of efficiency and productivity of all types of entities, both public and private, and from any sector of the economy, such as manufacturing companies, bank branches, even sporting entities. The group usually examines these types of problems from the perspective of data envelopment analysis, a technique from the field of nonparametric methods, to estimate efficiency and attain indicators of change in productivity over time.
The group possesses more than twenty years of experience in basic and applied research, assessing efficiency, estimating productivity, and benchmarking. The investigative capacity of the group's personnel is supported by their participation in numerous R&D projects financed mainly by the Ministry of Science and Technology and Generalitat Valenciana.
