4OR: A Quarterly Journal of Operations Research

4OR is a new quarterly journal jointly published by the Operations Research societies of Belgium (SOGESCI/ BVWB), France (ROADEF) and Italy (AIRO). As its name suggests, this journal is devoted to Operations Research. Any good paper related with Operations Research is therefore of potential interest to the journal. The journal is divided into four different sections of unequal importance. REGULAR PAPERS. This section is the core of the journal. The aim is to be able to publish good quality papers within a short period of time. We have therefore decided to process all papers in electronic form, and to have an uncommon policy with respect to major revisions: all papers needing a ``major revision'', i.e., a revision that cannot be reasonably expected to be undertaken within two months and/or that is likely to significantly alter the whole paper, are rejected. The refereeing process conforms with the usual standards of academic journals: it involves at least two independent referee reports and the advice of an appropriate area editor. INVITED SURVEYS. This section is limited to one paper per issue. It consistS of ``state-of-the-art surveys'' written by prominent researchers on invitation by the editors. INDUSTRY SECTION. This section offers a means of communication between OR practitioners and academics. Papers published in this section consist of case studies, state-of-the-art papers on the applications of OR techniques in industry or reflections on the practice of OR. PH.D. THESES. We publish abstracts of doctoral dissertations defended in Belgium, France or Italy. These abstracts are published under the responsibility of the supervisor of the work. Starting with the second issue of 2005, the subtitle changed from "Quarterly Journal of the Belgian, French and Italian Operations Research Societies" to "A Quarterly Journal of Operations Research"
