The aim of this paper is to illustrate the measurement of productive efficiency using Nerlovian indicator and metafrontier with data envelopment analysis techniques. Further, we illustrate how profit efficiency of firms operating in different regions can be aggregated into one overarching frontier. Sugarcane production in three regions in Kenya has been used to illustrate these concepts. Results show that the sources of inefficiency in all regions are both technical and allocative, but allocative efficiency contributes more to the overall Nerlovian (in)efficiency indicator.

Linear programming (LP) is the most widely used optimization technique for solving real-life problems because of its simplicity and efficiency. Although conventional LP models require precise data, managers and decision makers dealing with real-world optimization problems often do not have access to exact values. Fuzzy sets have been used in the fuzzy LP (FLP) problems to deal with the imprecise data in the decision variables, objective function and/or the constraints. The imprecisions in the FLP problems could be related to (1) the decision variables; (2) the coefficients of the decision variables in the objective function; (3) the coefficients of the decision variables in the constraints; (4) the right-hand-side of the constraints; or (5) all of these parameters. In this paper, we develop a new stepwise FLP model where fuzzy numbers are considered for the coefficients of the decision variables in the objective function, the coefficients of the decision variables in the constraints and the right-hand-side of the constraints. In the first step, we use the possibility and necessity relations for fuzzy constraints without considering the fuzzy objective function. In the subsequent step, we extend our method to the fuzzy objective function. We use two numerical examples from the FLP literature for comparison purposes and to demonstrate the applicability of the proposed method and the computational efficiency of the procedures and algorithms.

Amin, G. R., A. Emrouznejad (2013). “A new DEA model for technology selection in the presence of ordinal data.” International Journal of Advanced Manufacturing Technology, 65 (9-12) 1567.

This paper suggests a data envelopment analysis (DEA) model for selecting the most efficient alternative in advanced manufacturing technology in the presence of both cardinal and ordinal data. The paper explains the problem of using an iterative method for finding the most efficient alternative and proposes a new DEA model without the need of solving a series of LPs. A numerical example illustrates the model, and an application in technology selection with multi-inputs/multi-outputs shows the usefulness of the proposed approach

Managing Service Productivity: Call for book chapter proposals

Modern economies are emerging to meet and satisfy higher expectations for efficient and effective services. Managing service productivity examines complex service issues, challenges, operations and suggests the use of appropriate benchmarking techniques to improve service performance.

We have taken the initiative to edit the book on “Managing Service Productivity”. This book describes how the frontier efficiency methodology such as DEA and other techniques such as MCDM could help service industry to improve their performance by (1) providing ranking of best-practice efficient service units, (2) identifying sources of inefficiency for each service unit (3) determining potential improvement targets for each of the inefficient service units, (4) identifying peers for each service organization, and (5) providing a basis for continuous performance improvement. This information could be useful for the service management to improve service productivity, profitability, sustainability, and quality and effectiveness of service deliveries.
We aim to provide a collection of recent and state-of-the-art contributions to this emerging topic, and will be published in the “International Series in Operations Research & Management Science” (Springer).

We wish to invite you to contribute to this edited book. We are interested in topics including, but not limited to, service productivity in healthcare, education, financial services, transports, utilities, information technology, and tourism and leisure activities. We hope that you will be able to accept our invitation. At this stage, we invite you to submit [by December 15, 2012] a 1-2 page chapter proposal clearly explaining the goals and objectives of your proposed chapter.

Selection process and timeline

Since timeliness is crucial to the success of this editorial project, we would assume the following schedule:

Chapter proposals January 31, 2013
Decisions from editors February 15, 2013
Full submission of chapters April 30, 2013
Feedback of reviews May 31, 2013
