RULES OF SUBMISSION AND INSTRUCTIONS TO AUTHORS

Authors willing to submit their papers for publication in Pesquisa Operacional must send a word file with the manuscript by e-mail to horacio@lac.inpe.br or sobrapo@sobrapo.org.br.

The file should be accompanied by a letter of submission by the author (or authors). In this letter, the corresponding author must include his (her) mailing address, phone and fax numbers, and e-mail address. The standards specified below must be rigorously observed. Non-compliance with the standards may cause considerable delays in the processing of the paper.

Content, Text Organization and Format

The paper must be typed in Word for Windows 6.0 or newer version (font Times New Roman, single spacing). Margin specifications are as follows:

Upper: 33 millimeters
Lower: 25 millimeters
Left and right: 29 millimeters
Gutter: 3 millimeters
Header: 21 millimeters
Footer: none.
Mirrored margins

The text must be printed using a laser or ink jet printer in one side of A4 paper (210 x 297 millimeters). The pages must be numbered with a pencil on the reverse side; for this reason references must be made to sections and not to page numbers.

Size and option for characters are as follows:

Article title: 12 uppercase bold
Author (s): 12 bold uppercase / lowercase
Origin: 11 normal uppercase lowercase
Abstract and keyword titles: 11 bold uppercase / lowercase
Keywords: 11 normal
Abstract texts: 10normal
Article text: 11 bold (titles); 11 normal (text)

2. The first page shall receive only paper title, name (s) and origin (s) of author (s), abstracts and keywords. The title shall be centered and put below the first third of 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 line. This page, only, admits a footnote containing data about authors, if they prefer to use this format. After two single spaces an abstract in the language of the text should be included, followed by two single spaces and an abstract in English. If the author's native language is Portuguese but the article is written in another language, the abstract in English must be followed by an abstract in Portuguese. Each abstract must contain no more than 150 words, which is the limit for publication in IFORS' IAOR. After each abstract three keywords will be provided in the same language.

3. The paper must begin with an introduction. Footnotes outside the first page are not permitted. Acknowledgements must not exceed 5 lines and must be placed after the main text, before the references.

4. Graphical objects should be incorporated into the text by the text editor. Objects made with several elements should be grouped. A functional alternative is to have them drawn with Indian ink on vegetable paper. In this case, the respective titles should be incorporated in each drawing and its location in the text must be clearly indicated. Use of shadowing is not recommended. Color printing is not supported.

5. Mathematical expressions must be numbered consecutively. Whenever possible, one must avoid notation that unnecessarily uses more than one line (use for example x/(y-l); exp (x)). If the paper is written in Portuguese, French or Spanish, commas should be used in decimal numbers instead of points.

6. 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: [AY92], or Altinkemer & Yu (1992). The following models should be used for papers published in journals (1), books (2), chapters contributed in edited books (3) and internal reports and theses (4):

(1) Altinkemer, K. & Yu, Z. (1992). Topological design of wide area communication networks. Annals of Operations Research, 36, 365-382.

The aim of Pesquisa Operacional is to publish papers produced by the Operational 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 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 articles will be evaluated by at least two referees using a double blind review system and the final decision will be communicated to the main author by the Editor-in-Chief.

Pesquisa Operacional publishes papers written in English. Submission of a manuscript implies that its publication has been approved by all co-authors, if any, as well as by the responsible authorities at the institution where the work has been carried out, that the author(s) will be implicitly giving away his/her (their) rights to SOBRAPO and will be implicitly certifying that eventual third parties rights are not being violated. The author(s), however, remains (remain) responsible for the contents of his/her (their) published article. Although the information in this journal is believed to be true and accurate at the time of its press, the editors and SOBRAPO do no accept any legal responsibility for any errors or omissions that may have occurred or that may be later identified.
