Summary of achievements

Having gained an MBA from Harvard University I have joined the Lean Engineering Research Group at DMU in 2001 as a Research Fellow. In 2005 I completed my PhD studies in which I developed methods for "Predicting the Effect of Variability on the efficiency of Flow Processing Systems". The research investigated the effects of variability on flow processing lines with the overall aim of enabling suitable methods, to be selected, for maintaining flow processing efficiency. In achieving this aim a detailed examination of both flow processing and variability was undertaken. In the case of the later area the research identified the various causes and types of variability on flow processing lines. A novel method was then developed for categorising sources of variability that can be used to decide appropriate methods of overcoming its unfavourable effects.

During my period within the Lean Engineering Research Group I have undertaken taught at both undergraduate level, ie BSc (Hons) Lean Engineering and at postgraduate level, ie MSc Rapid Prototyping and MSc Mechatronics. In addition I have been involved in delivering work-based training in lean practices within the Repair and Overhaul facilities of Rolls-Royce.

Before joining De Montfort University, I have gained a good experience in teaching. I was working as a Lecturer at City University – London. I worked as visiting Academic in different countries as USA and Egypt. I did enjoy working in an International environment which has gained me more knowledge about the countries culture and environments. I have been appointed as a Lecture at NY Institute of Technology. My main area in both Academic Institute was management and operations.

I have developed a Virtual Reality distance learning modules for San Diego University which is still in use till the moment.

PhD Abstract

Manufacturing organisations are continually facing challenges through the action of competitive market pressures. Currently such organisations aim to gain competitive advantage by offering wider ranges of products, shorter lead times, increased delivery reliability and costs reductions on a year-by-year basis. In order to achieve this aim flow processing systems are increasingly being adopted, by a wider range of industrial sectors, as part of an overall lean manufacturing approach. As a result the levels of product and process variability that flow processing systems need to effectively contend with are significantly increasing.

The current research has, therefore, investigated the effects of variability on flow processing lines with the overall aim of enabling suitable methods, to be selected, for maintaining flow processing efficiency. In achieving this aim a detailed examination of both flow processing and variability has been undertaken. In the case of the later area the research has identified the various causes and types of variability on flow processing lines. A novel method has been developed for categorising sources of variability that can be used to decide appropriate methods of overcoming its unfavourable effects.
