Operations Research

EDITORIAL POLICY

Operations Research publishes quality operations research and management science work of interest to the OR practitioner and researcher in the three substantive categories: operations research methods, data based operational science, and the practice of OR. Included are papers reporting underlying data based principles of operational science, observations of operating systems, contributions to the methods and models of OR, case histories of applications, review articles, and discussions of aspects of such subjects as the administrative environment, the history, policy, practice, future, or arenas of application of operations research.

Papers on transportation are generally published in the ORSA publication, Transportation Science. Papers whose main contribution is to the underlying mathematics are more appropriate for the joint ORSA/TIMS publication, Math- ematics of Operations Research.

Complete studies that contain data, computer experiments, etc., and integrate the theory, methods, and applications are of particular interest. Thus, we encour- age case studies of lasting value. Contributors should submit informal descriptions of cases to the joint ORSA/TIMS publication Interfaces.

A "Technical Notes" section contains brief articles on all of the topics men- tioned above. Commentary appearsjin a "Letters to the Editor" section.

All papers published in Operations Research are refereed. Initial refereeing of clear, concise, well-written papers normally takes about four months for papers of average length, but generally a shorter time for notes.

Decisions on manuscripts for publication in Operations Research will be based, in part, on the answers to such questions as: Does this paper make a new and substantial contribution to the literature of operations research? Will it be of interest to a significant group of OR workers? Does the paper give sufficient introductory and summary material to inform readers of the content, importance, and possible fields of application of the material covered? It is clearly, concisely, accurately and logically written? Could it benefit from condensation or expansion? Is its character clear from title, abstract and text? Does the paper describe its relations to previously published work, and does it give adequate credit and references to this work?

INSTRUCTIONS FOR CONTRIBUTORS

Authors should submit four copies of manuscripts directly to the appropriate Area Editor. Papers that are not in the fields covered by the Area Editors should be sent to the Editor, William P. Pierskalla, 2 Denford Drive, Newtown Square, Pennsylvania 19073. Papers should not be sent to the Associate Editors.

Submission of a manuscript is a representation that the paper has been neither published nor submitted for publication elsewhere, and that, if the work is officially sponsored, it has been released for open publication. The manuscript should be accompanied by a Copyright Transfer Agreement from the authors (or their employers-whoever holds the copyright) transferring the copyright to ORSA. The form for this agreement is printed in the March-April issue of this journal and is also available from the Editor and the Business Manager. This written transfer of copyright, which previously was assumed to be implicit in the



act of submitting a manuscript, is necessary under the 1978 U.S. Copyright Law in order for ORSA to continue disseminating operations research results as widely as possible. Copies of a manuscript will not be returned to an author unless he makes a specific request, or unless reviewers have provided annotatiens that will be of use to him.

Observe the following points in preparing manuscripts (those not conforming closely to these instructions will be returned to their authors for appropriate revisions):

1. Readability. The abstract and the introduction of every paper must be free of unnecessary jargon and clearly readable by any ORSA member. The abstract should be self-contained, summarize the problem, principal results and conclusions; it should not contain formulas or references nor exceed 200 words. The introduction must clearly state the problem, the results to be found in the paper and their significance to the operations research community. The introduction does not have a section heading. The main sections of the paper must be readable, the level of mathematics and/or terminology appropriate to the topic, and the material logically presented.

2. Style. Your paper's message will be enhanced if it is presented in active, forceful, and concise prose. Since good writing is a craft at least as difficult as doing operations research, before beginning your paper you will be well advised to refresh your recollection of some of the most important points of good style to remember by spending some time with a source of good editorial advice, such as Donald H. Menzel, Howard Mumford Jones, and Lyle G. Boyd, Writing a Technical Paper, McGraw-Hill, New York, 1961. While the Editor and his staff will correct the minor lapses from good style in your manuscript, they cannot undertake wholesale revisions of poorly written papers. It is a good idea to run your manuscript through more than one draft, and to have an early one reviewed by someone who can give you effective advice on style. There is no a priori limit to the number of pages for a paper; however, conciseness and clarity of presentation should be stressed.

3. Spacing and format. Double-space manuscripts throughout (including the abstract, subsidiary matter and references) with the original in typewritten form. Put subsidiary matter on separate sheets (see Figures and Tables). The introduction does not have a section heading; begin numbering with the main sections.

4. Footnotes. Operations Research does not use footnotes; incorporate subsidiary material that would otherwise appear in footnotes in the main text (possibly in parentheses or brackets), or place it in a section at the end of the text. In particular, place the usual acknowledgments of presentation, support, and assistance in such a final section.

5. References. List only those references that are cited in the text. References in the text should be cited by the author's surname and the year of publication- for example, Flood (1962). If the reference has two authors cite both surnames and the year of publication. If the reference has more than two- authors cite the fiLrst author's surname followed by et al. and the year of publication. If there is more than one reference by the same author with the same year of publication, the first citation appearing in the text would read: Flood (1962a), the second citation would read: Flood (1962b), etc. At the end of the paper list references alphabetically by the surname of the first author. Do not number the reference list. For journal references give the author, year of publication, title, journal name, volume, and pages; for book references give the author, year of publication, title, publisher, city, and state-for example, FLOOD, M. M. 1962. New Operations Research Potentials. Opns. Res. 10, 423-

436. MORSE, P. M., AND G. E. KIMBALL. 1951. Methods of Operations Research.

Massachusetts Institute of Technology, Cambridge, Mass.

6. Mathematical expressions. Use the solidus whenever possible in preference to built-up fractions, e.g., a/(1 - b) rather than _ write complicated

exponentials in the form exp ( ); avoid subscripts or superscripts on subscripts or superscripts; and, in general, minimize unusual typographical requirements. Make subscripts and superscripts large and clear. On first occurrence label unusual or ambiguous symbols; for example, distinguish the letter "oh" from the numeral 4'zero." The difference between upper and lower case letters should be clear. Display only those mathematical expressions that must be numbered for later reference or need to be emphasized. Put numbers at the right of the mathematical expressions.

7. Figures and tables. Draw figures in black ink on white paper in a form suitable for photographic reproduction. Make lettering of uniform size and suffi- ciently large to be legible when the figure is reduced to final size. Send originals of typed tables suitable for photographic reproduction. Designate figures by arabic numbers, designate tables by roman numerals, and type the legends for the figures and tables on a single separate sheet rather than placing them on the originals. Please proofread carefully since later changes can be made only by submitting new originals.

8. Reporting computational experience. In reporting computational experience on the efficiency of algorithms follow the guidelines given in Operations Research volume 27, number 1, entitled "Reporting Computational Experience in Operations Research." Copies of these guidelines may be obtained from the ORSA Business Manager, 428 East Preston Street, Baltimore, Maryland 21202, USA, or from the Editor, William P. Pierskalla, 2 Denford Drive, Newtown Square, Pennsylvania 19073, USA.

9. Abstract and introduction. Preface each article with a self-contained abstract that summarizes the problem and the principal results and conclusions. The abstract should not contain formulas or references and should not exceed 200 words. The abstract and introductory material should be written in an expository style that will be comprehensible to readers who are not technical experts in the subject matter. The introduction does not have a section heading.

10. Subject Classification for the OR/MS Index. It is the responsibility of each author to determine the appropiate subject classification and accompanying descriptive phrase for work submitted. A complete list of subject categories appears on pp. vii-viii. Each subject category is indicated by a specific number. Authors will chose from one to three subject categories for each manuscript submitted. For every category chosen, the author must write a short phrase which places the paper in its proper context within the subject category. (The phrase can be a concise rendering of the title, or it may specify some aspect of the paper which is important but not apparent in the title.) The total length of each phrase, including spaces and punctuation, must not exceed 60 characters. Subject categories/phrases must accompany the Copyright Transfer Agreement of every manuscript submission (this includes articles, technical notes, and letters).

Example. A paper entitled, "Cost-Effectiveness in Urban Transportation" would be

classified under two subject categories: 71 (Cost/Benefit Analysis), and ?831 (Transportation). On the Subject Classification Form the numbers and accompanying phrases would be:

? 71 Urban transportation 831 Cost-effectiveness in urban transportation

11. Reprints. Operations Research does not have page charges, nor does it supply free reprints. Authors of accepted articles may order reprints at reasonable rates at the time they submit their corrected galley proofs. Reprints of individual articles are not available from ORSA.
