The aim of Pesquisa Operacional is to publish papers produced by the Operations Research (OR) scientific community in order to promote its integration and to disseminate the scientific knowledge generated within it.
Pesquisa Operacional publishes theoretical and applied papers of any OR sub-areas, as well as surveys on topics of interest and papers on the history or methodology of OR. Submitted papers must be written in English, must be original, and must not have been accepted for publication (or published) by a refereed journal, nor be in the process of evaluation for publication by any other periodical. In addition to originality and relevance, it will be taken into account the quality of presentation (clarity, style and organization of the text) and the adequacy of the text to the interests of the readers of the journal. Submitted papers will be evaluated by at least two referees using a blind review system and the final decision will be communicated to the corresponding author by the Editor-in-Chief.
Pesquisa Operacional publishes papers in English. When submitting a manuscript the author(s) will be implicitly giving their rights to the Brazilian Operations Research Society (SOBRAPO) and saying that third parties rights are not being violated.
Form and preparation of manuscripts
Authors willing to submit their papers for publication in Pesquisa Operacional must use the online submission system of Scielo (www.scielo.br/pope). The paper should be accompanied by a letter of submission by the author(s). In this letter, the corresponding author must include his (her) mailing address, phone and fax numbers, and e-mail address. The specifications indicated below must be rigorously observed. Noncompliance with the specifications may cause considerable delays in the processing of the paper.
Content, Text Organization and Format
In the first page, only the paper title, name(s) and affiliation(s) of the author(s), abstracts and keywords are contained. The title must be centered and placed below the first third of the useful page height. This must be followed by two single spaces and the name of each author (without titles or positions), followed, in the next line, by the name of his (her) institution, all left-justified but on the right half of the page. Onl at this page a footnote containing data about authors is allowed, if this format is preferred. After two single spaces follows the abstract. The abstract must contain no more than 150 words, which is the limit for publication in IFORS' IAOR. After the abstract three keywords must be provided.
The paper must begin with an introduction. Footnotes are not permitted. Acknowledgements must not exceed 5 lines and must be placed after the main text, before the references.
Graphical objects should be incorporated into the text by the text editor. Objects made with several elements should be grouped. Use of shadowing is not recommended. Color printing is not supported.
Mathematical expressions must be numbered consecutively.
References must be ordered in alphabetical order of the first author's last name. The citation in the text must contain name(s) and year of publication, abbreviated or not. Example: [MPL03], or Maculan, Plateau & Lisser (2003), or Maculan et al. (2003). The following models must be used for contributed chapters in edited books, papers published in periodicals and internal reports or theses, respectively: Bechara JJB & Galvão RD. 1987. The use of interactive computing for vehicle routeing. In: Recent Advances in System Modelling and Optimization [edited by L. Contesse, R. Correa and A. Weintraub], Springer Verlag, 22–32.
