EDITORIAL PREFACE

It is my overwhelming pleasure to inform you of the success the first two issues of our journal JJMIE has made at all levels. For instance, tens of supporting and encouraging comments were received during the last couple of months. Moreover, quite a big number of professionally distinguished contributions have down poured from elite local and international scholars in the fields of Mechanical and Industrial Engineering. Needless to say, this echoing success is due to the cooperative efforts of the contributors, the reviewers, the editorial board, the technical aids and most importantly the limitless support of the Ministry of Higher Education and Scientific Research and the Hashemite University officials.
