0 A AIA

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

Complete studies that contain data, computer experi- ments, and model validation, and that integrate theory, methods, and applications are of particular interest. Thus, we encourage case studies of lasting value. Contributors should submit informal descriptions of cases to Interfaces.

In addition to the regular ARTICLES section, there are three special sections: OR PRACTICE contains practitioner- oriented applications, tutorials, and surveys. Application papers whose utility is as yet undemonstrated in practice or that are not tailored for practitioners should be submitted to the appropriate Area Editor. The OR FORUM section publishes papers on history, policy, analyses of current and future trends, and related subject matter. TECHNICAL NOTES

contains brief articles on all of the topics covered by the Jour- nal. For more information on subject coverage and editorial policy, see the Editorial and Area Editor statements published in the January-February 1993 issue.

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

Decisions to publish manuscripts 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 context, importance, and possible fields of application of the material covered? Is it clearly, concisely, accurately and logically written? Could it benefit from con- densation or expansion? Is its character clear from the title, abstract and text? Does the paper describe its relation to previously published work, and does it give adequate credit and references to this work?

It is to be understood that the final decision concerning publication rests with the Editor.

INSTRUCTIONS FOR CONTRIBUTORS

GENERAL CONSIDERATONS

Authors should submit four, double-spaced typewritten copies of manuscripts directly to the appropriate Area Editor. The copy must be clearly legible. Also needed are: a copyright transfer agreement, a statement of contribution, and a cover letter. Papers not in the fields covered by the Area Editors (listed on the inside front cover of each issue) should be sent to

H. Donald Ratliff, Editor School of Industrial and Systems Engineering Georgia Institute of Technology Atlanta, GA 30332-0205

for assignment. Papers should not be sent to the Associate Editors.

Submission of a manuscript is a representation that the paper has neither been 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 INFORMS. The form for this agreement is printed in most issues of this journal and is also available from the Managing Editor and the Executive Director of INFORMS. 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 INFORMS to con- tinue disseminating operations research results as widely as possible.

Manuscripts will not be returned to an author unless spe- cifically requested, or unless reviewers have provided anno- tations that will be of use to the author.

The text should be arranged as follows: title page, abstract, introduction, main sections, appendix, acknowledgment, and references. The appendix and acknowledgment are optional.

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

1. Statement of Contribution. A statement of contribution is required for each submitted paper. The form will appear in nearly every issue of the Journal and should be completed and submitted at the time a paper is sent to an Area Editor. The purpose of this statement is to aid area editors and reviewers in determining if the paper meets its stated objec- tives. Once a paper is accepted for publication, this statement will serve as the basis for the In This Issue column.

When preparing this statement, include the following: Why is the topic that is addressed in the paper important? What specific contributions does the paper make to operations research? What do you believe is the basis for publication? Provide a brief assessment of the near and long-term implica- tions of the contribution.



Keep the statement brief, preferably fitting into the space allocated on the printed form. Try not to overflow the page, however, a longer statement may be submitted if you believe that such an explanation is necessary. The statement should be expository and contain no mathematical notation. Attach one copy of the completed form to the submission. Failure to complete this item will delay the start of the review process.

2. Readability. The abstract and the introduction of every paper must be free of unnecessary jargon and clearly readable by any INFORMS member. These sections should be written in an expository style that will be comprehensible to readers who are not technical experts in the subject matter.

3. Title Page. Each paper should have a title page that contains the authors' names and addresses. The usual acknowledgments should be placed in a separate section at the back of the manuscript.

4. Abstract. Preface each article with a self-contained, one paragraph abstract that summarizes the problem and the principal results and conclusions. It should not contain for- mulas, references or abbreviations, nor exceed 200 words.

5. Introduction. The introduction must clearly state the problem, the results to be found in the paper and their sig- nificance to the OR community. It should not contain equations or mathematical notation. The introduction does not have a section heading or a number.

6. Main Sections. The main sections of the paper must be readable, the level of the mathematics and/or the terminol- ogy appropriate to the topic, and the material logically presented. Begin section numbering and headings with these sections.

7. Style. The message of your paper 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 ad- vised to refresh your acquaintance with the most important points of good style by spending some time with a source of good editorial advice, such as Writing a Technical Paper by Donald H. Menzel, Howard Mumford Jones, and Lyle G. Boyd (New York: McGraw-Hill, 1961). While the Editor and staff will correct minor lapses from good style in your manuscript, they cannot undertake wholesale revisions of poorly written papers. There is no a priori limit to the number of pages for a paper; however, conciseness and clarity of presentation are important publication criteria.

8. Spacing and Format. Double space manuscripts throughout, including the abstract, subsidiary matter (list of captions, for example), and references. No line-printed computer printouts will be considered for publication. In general, keep figures and tables to a minimum that is consistent with an adequate presentation of the textual information.

Each page of the manuscript should be numbered. Indent the first line of each paragraph. Spelling and hyphenation will follow Websters Third New International Dictionary (unabridged).

9. 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 Notes section at the end of the text, before the Acknowledgment and References. Desig- nate notes by using superscript numerals placed in serial order throughout the text.

10. Acknowledgment. Place acknowledgments of presentation, support and assistance in a final section that precedes the References, not on the title page.

11. 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 or three authors, cite all of the authors' surnames and the year of publication- Flood, Smith and Jones (1982). If the reference has more than three authors, cite the first author's surname followed by et al. and the year of publication-Brown et al. (1985). 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. Do not use parentheses or brackets for dates when the citation is already enclosed within parentheses. At the end of the paper list references alphabetically by the last name of the first author. Do not number the reference list. Double space this final section.

For journal references, give the author, year of publication, title, journal name, volume, and pages-for example:

FLOOD, M. M. 1962. New Operations Research Potentials. Opns. Res. 10, 423-436.

For book references, give the author, year of publication, title, publisher, city, state, and pages-for example:

MORSE, P. M., AND G. E. KIMBALL. 1951. Methods of Operations Research. John Wiley, New York, 44-65.

For references to working papers or dissertations cite the author, title, type of document, department, university, and location, for example:

ROSENWEIN, M. 1986. Design and Application of Solution Methodologies to Optimize Problems in Transportation Lo- gistics. Ph.D. Dissertation. Department of Decision Sci- ences, University of Pennsylvania, Philadelphia.

12. Mathematical Expressions. Within the text, use the solidus whenever possible in preference to built-up frac-

tions, e.g., a/(1 - b) rather than a write complicated

exponentials in the form exp( ); avoid subscripts or superscripts on subscripts or superscripts; and, in general, mini- mize unusual typographical requirements. For displayed equations, use built-up fractions. Avoid lengthy equations that will take several lines to typeset (possibly by defining terms of the equations in separate displays).

Make subscripts and superscripts large and clear, and shown in a clearly inferior or superior position. The letter 1 and the numeral 1 and the letter 0 and the numeral 0, which are identical on most keyboards, should be identified. Sym- bols and Greek letters should be identified clearly: On their first occurrence, label unusual or ambiguous symbols by marginal notes. The difference between upper and lower case letters should be clear.

Display only those mathematical expressions that must be numbered for later reference or that need to be emphasized. Number displayed equations consecutively throughout the paper; do not number equations by section numbers. Appendix equations can be labeled Al, A2, etc. The numbers should be placed in parentheses to the right of the equation.



13. Reporting Computational Experience. In reporting computational experience on the efficiency of algorithms follow the guidelines given in Operations Research, Volume 29, No. 2, "Reporting Computational Experience in Operations Research. "

14. Tables. Tables should be numbered with roman numerals, have a title, and be referred to sequentially in the text. Column headings should be brief and not use abbreviations. Do not use vertical rules. The use of footnotes is encouraged; designate these by lower case letters. The submission of original tables suitable for reproduction is not necessary; all tables will be typeset for consistency. Each table should be on a separate sheet and not interleaved in the text.

15. Figures. Line drawings should be prepared in black ink or preferably via a laser printer or plotter on white bond or vellum paper. For best results, fit the figure onto a 8?/2 x 11 inch sheet with at least a 1 inch margin all-around. Orig- inal drawings will be required on acceptance of a paper. Copies are sufficient for reviewers.

Lettering should be done on a computer, with a mechani- cal lettering set or its equivalent. The figure should be of sufficient size so that after photoreduction, letters and numbers are legible.

Do not clutter the figure with information that makes it difficult to read. All details on the figures should be checked carefully because correction on proofs necessitates reshooting.

Each figure must be cited and will be placed in the order mentioned in the text. Each figure must have a caption and a number (arabic). Do not place the caption on the original of the figure-these go on a separate sheet. Do not differentiate between illustrations and figures.

Lines must be sufficiently thick to reproduce well, and decimal points, periods and dots must be sufficiently large to allow for reduction. The same type of lettering should be used for all figures. The figure and the lettering should be in proportion so that both can accommodate reduction. Do not use different sized type within a figure.

16. Subject Classification Scheme for the OR/MS Index. Determine the appropriate subject classifications (up to 3) and accompanying descriptive phrases for all work submitted. A complete list of categories appears at the back of most issues; refer to the revised scheme as it appears in Volume 37, No. 1 (January-February 1989) and in subse- quent issues. Choose from one to three subject categories for each manuscript. For every category chosen, write a short phrase that puts the paper in context. (The phrase can be a concise rendering of the title, or it may specify some aspect of the paper that is important but not apparent in the

title.) The length of each phrase, including spaces and punc- tuation, should not exceed 60 characters. This information will be printed on the title page of every article, technical note, and letter that is published.

Subject categories and phrases must either appear on the title page of the manuscript (this is the preferred method), or authors may use the form provided (see the bottom half of the Copyright Transfer Agreement).

Do not repeat the subject classifications from the subject categories. The accompanying phrase should help to further clafrfy the paper within a subject category.

17. Reprints. Operations Research does not have paper 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 INFORMS.
