• Sommario/riassunto: There are many academic references describing how RMs are made, but few that explain why they are used, how they should be used and what happens when they are not properly used.In order to fill this gap, the editors have taken the contributions of more than thirty RM practitioners to produce a highly readable text organized in nine chapters. Starting with an introduction to historical, theoretical and technical requirements, the book goes on to examine all aspects of RM production from planning, preparation through analysis to certification, reviews recent development areas, RMs for li
