An Important Message From the Editor-in-ChiefDear Friends,

All journeys come to an end at some point of time and place. My journey with the International Journal of Performability Engineering (IJPE) began in July 2005 at Jaipur, India. Of course, the preparation for this arduous journey had begun in 1992, when I was invited to join National Environmental Engineering Research Institute, (NEERI), Nagpur in India as Director-grade-Scientist. At NEERI, I learnt that merely ensuring high reliability/dependability of products, systems, or services economically should not be an ultimate goal of an engineer but also how these should be produced must also be his concern in the context of material and energy requirements, creation of environmental pollution and wastage or in other words ensuring clean and economic production. We need to use minimum resources and optimize the production process while minimizing waste and environmental pollution. This is absolutely necessary to meet the requirement of increasing population with fast depleting resources of the world and looking to the alarming rate of degradation of Earth’s environment. Our emphasis has to shift to the concern for developing environment friendly products, systems and services. We need to dematerialize the production process and make use of recycling, reuse and remanufacturing and minimize the use of energy during manufacturing and use while maximizing the performance in terms of quality, reliability and safety.

Initially, I had been a student of reliability engineering [1, 2] since 1967 and IEEE Reliability Society of U.S.A. awarded me a plaque in appreciation of my research and educational contributions in reliability in 1995. In fact, I had always thought that national prosperity can be achieved if we produced high quality and reliability products, system and services. In deed that was just half of the truth about the matter. My invitation to NEERI, Nagpur India, led me to get attracted to the field of Clean Production and I published a book on Clean Production: Environmental and Economic Perspectives [3] with Springer Verlag in 1996.The urgency of this requirement arose from the consideration that we are consuming resources at a much faster rate while generating tremendous waste at the same time, leading to environmental pollution at a very fast rate, which may even threaten the existence of humanity on the Earth.

Returning to my parent institute, Indian Institute of Technology, Kharagpur, I started new courses in this area and students showed keen interest in this new discipline.

The IJPE, in fact, was started with the objective of invigorating the process of designing systems, products and services that are sustainable and bringing researchers in the area of reliability/dependability and researchers in the area of sustainability on a common platform, which was non-existent.  The concept of performability as introduced in the inaugural Editorial of this journal [4] was put forward based on the composite attribute of dependability and sustainability. As of today, dependability can be measured and assessed through various attributes but we do not have any convincing measure to assess the attribute of sustainability. We need to find that out. Later on, the question of integrating the attributes of performance of a product, system or service over its entire life cycle can be tackled. It can be very well stated that nineteenth Century after WW II was an era of reliability/ dependability while 21st Century would be the Century of sustainability combined with dependability.

At this moment we have highly qualified specialists of dependability, which in fact is a composite attribute and can be derived from other attributes but none seems to know how we can integrate dependability with sustainability [6, 7] entailing all considerations to achieve a single figure of merit for the purpose of comparing performance, numerically. If we achieve this feat, then only we would be able to specify performability of a product, system or service, numerically and design it in a product, system or service, or even compare the performability of different products quantitatively.

On August 13, 2015, we have signed an agreement between RAMS Consultants, India and Totem Publishers Inc., U.S.A. transferring the ownership of IJPE to the new publisher, whose owner is Professor Eric Wong of University of Texas, Dallas, USA (, Professor & Director of International Outreach & Director of Advanced Research Center on Software Testing and Quality Assurance. He is also the Vice President Vice President for Publications of the IEEE Reliability Society. This is the day when according to data from Global Footprint Network, as cited by WWF, the humanity’s annual demands on nature exceeded what Earth can regenerate in this year, and has moved up from early October in 2000. This reminds us of our responsibility and commitment particularly of India, China and USA towards our planet Earth and importance of the mission of IJPE.

Now that I intend to bring my journey with IJPE to an end (nothing is everlasting - a reliability concept) on December 31, 2015, as has been already announced on the Homepage of IJPE (, I like to handover the responsibility of carrying forward the mission of IJPE to two new Editor-in–Chief Designates, Dr. Dianxiang Xu, and Dr. V. N. A. Naikan. Both Professor Xu and Professor Naikan are engaged in active research within the scope of IJPE and have editorial experience. I am sure that the journal will make fast progress toward achieving its goals under their able leadership.

Lastly I like to thank all who supported the cause of IJPE and made my journey comfortable. Thank you all.
