It is observed from Figure 1 that the research on GrLND issue has gained momentum on
that past 5 years (with a special issues dedicated to reverse logistics in Computers & Operations
Research Journal in 2007). Figure 2 highlights the degree of importance on publishing GrLND
issues by a given journal through representation of the studies in the respective journals from
1999 onwards. It can be observed that European Journal of Operations Research (EJOR) and
International Journal of Production Economics (IJPE) have published on GrLND. These two
figures would motivate future researchers to work on GrLND issue and appropriately targeting
the research journals for potential publications in the field. For a holistic review, a content
analysis of the literature has been carried out across specific categories, in order to understand
and gather interesting insights about the nature of research between the years 1999-2013.
