1. Manuscripts should be in English. The desired order of contents is Title, Author(s) and Affiliations, Abstract and Keywords, Main Text, Acknowledgements, References and Appendices. Tables and illustrations, complete with titles, labels and art work, should be placed in the text at the appropriate locations. All pages should be numbered consecutively.
2. Manuscripts must be typewritten, double spaced with wide margins on one side of white paper. The corresponding author should be identified (include an e-mail address). Authors should refer to a recent issue of APJOR for style. Papers should be restricted to 15-25 manuscripts pages (2500 to 6000 words). Longer paper will be subjected to a delay in publication.
3. The title should be descriptive and concise. In addition, an abbreviated title (no more than 50 characters) to be used as a running head should be supplied.
4. The abstract should be brief, self-contained, explicit and should not exceed 200 words.
5. Equations should be numbered sequentially in parentheses by the right margin. Equations and formulas should include the appropriate punctuation.
6. Table captions should be placed immediately above the table, while figure captions should be placed immediately below the figure.
7. References cited in the text should be listed at the end of the manuscript. They should be listed in alphabetical order of the first author's surname. References should not be numbered. The following examples should be followed:

   Hadley, G (1970). Nonlinear and Dynamic Programming. Reading, MA: Addison-Wesley Publishing Company.

   Powell, M J D (1970). A new algorithm for unconstrained optimization. In J Rosen, O Mangasarian, and K Ritter, (Eds.), Nonlinear Programming, pp. 86 - 95. New York: Academic Press.

   Tapley, B P and J M Lewallen (1967). Comparison of several numerical optimization methods. Journal of Optimization Theory and Applications, 1, 1-32.

   References should appear in the text as " ... Tapley and Lewallen (1967) ..." or as " ... (Tapley and Lewallen, 1967:28) ..."

   Full journal titles should be used, without any abbreviation. For example, use Operations Research rather than Oper. Res., and SIAM Journal of Applied Mathematics rather than SIAM J. Appl. Math.

8. Authors should submit a short statement (not more than 150 words) on important aspects of their professional career such as degrees obtained, positions held, research interests, and journals in which they have previously published.
9. Manuscripts can be submitted via online submission.
10. Authors are reminded that submission of a manuscript to APJOR is held to imply that it contains original unpublished work which is not under consideration for publication elsewhere.

Hardcopy submission of manuscripts is not accepted.
