Procedures for ranking technical and cost efficient units: With a focus on nonconvexity

factors effective on technical efficiency and ranking of efficient units in social security hospitals

introduction: iran's social security organization provides hospital services through direct treatment system (hospitals owned by the organization) and indirect treatment system (purchasing of hospital services and other health care services from other providers). the current research aims to assess technical performance and determine the relationship between activity size and efficiency level o...

Ranking of Efficient and Non-Efficient Decision Making Units with Undesirable Data Based on Combined Models of DEA and TOPSIS

Data Envelopment Analysis (DEA) is a method for determining the performance of units under evaluation of DMUs. Each decision-making unit using multiple inputs produces multiple outputs whose nature of outputs may be desirable or undesirable. Units whose performance score equals one are efficient. The concept of ranking decision makers because of the useful information they provide to decision m...

New Trends and Procedures of Program Assessment for Academic Units

Some consider assessment in terms of a systematic way of gathering and evaluating information within educational system and particularly higher education. Since, the term ‘’assessment’’ refers and relates to administrative processes, this paper has shed light some consideration on how it can benefit the members of department and program. Program assessment ultimately emphasizes on direction for...

Ranking efficient units by regular polygon area in DEA

Ranking DEA Efficient Units with the Most Compromising Common Weights

One may employ Data Envelopment Analysis (DEA) to discriminate decision-making units (DMUs) into efficient and inefficient ones base upon the multiple inputs and output performance indices. In this paper we consider that there is a centralized decision maker (DM) who ‘owns’ or ‘supervises’ all the DMUs. In such intraorganizational scenario the DM has an interest in discriminating the efficient ...
