PCAM TEMPLATE

Important General Instructions for Authors

  • Read All Guidelines: Authors are required to read these Manuscript Preparation Guidelines and PCAM's general "Author Guidelines" in their entirety before submitting a manuscript. Careful preparation according to these instructions is crucial for a smooth review and publication process.
  • Use of Template: All manuscripts must be prepared using the official PCAM LaTex template, which can be downloaded from the journal website. The template includes preset formatting for page layout, fonts, headings, and other stylistic elements.
  • International Collaboration: PCAM prefers and actively encourages authors to submit articles resulting from international collaborative research, ideally involving multiple authors from different countries. This aligns with our mission to foster a global exchange of knowledge in industrial engineering and systems optimization.
  • Manuscript Withdrawal: Authors are strongly discouraged from withdrawing a submitted manuscript once it has entered the publication process (e.g., peer review, copyediting, layout). Journal Problems of Computational and Applied Mathematics (PCAM - in uzbek Hisoblash va amaliy matematika muammolari) invests significant time and resources in processing each submission.
  • Similarity Check: All submitted manuscripts are subject to a similarity check using plagiarism detection software (e.g., Turnitin). Manuscripts with a similarity score of more than 30% (excluding properly cited quotations and the reference list) will be automatically rejected without further review. Authors must ensure the originality of their work and appropriately cite all sources.

OUTLINE OF MANUSCRIPT PREPARATION

This guide details the specific requirements for preparing your manuscript for submission to PCAM.

1. CATEGORY

Authors must categorize their manuscript during the submission process. Select the category from the list below that most accurately describes your work:

  • Research Article: Involves the construction or testing of a model or framework, action research, testing of data, market research or surveys, or empirical, scientific, or laboratory research. This category typically presents original research findings.
  • Literature Review: Provides a comprehensive summary and critical analysis of existing research on a specific topic, offering a perspective on the current state of the field and potential future directions. Review articles are expected to be thorough and typically cite a significant number of primary references (commonly around 100).
  • Technical Paper: Describes and evaluates technical products, processes, or services, often focusing on practical application and innovation in industrial engineering.
  • Conceptual Paper: Develops hypotheses, frameworks, or theoretical models without being primarily based on empirical research. These papers are often discursive and may involve philosophical discussions or comparative studies of existing theories and concepts.
  • Case Study: Describes actual interventions, experiences, or in-depth analyses of specific situations or entities within organizations or industrial systems. Case studies may be subjective and do not generally report on extensive empirical research. Descriptions of legal cases or hypothetical case studies used as teaching exercises also fit this category.

2. LANGUAGE

  • Manuscripts submitted to PACM primarily use Russian and English with a preference for American English spelling and conventions.
  • Authors must ensure their manuscript is written in clear, concise, and grammatically correct English and Russian. Thorough proofreading by the authors or a professional language editing service is strongly recommended before submission.
  • Although manuscripts in Uzbek may be considered at the time of initial submission, the use of English or Russian are highly recommended to avoid delays in the evaluation process. If a manuscript submitted in Uzbek is accepted for publication after peer review, the author(s) will be responsible for arranging and covering the cost of professional translation into high-quality, proofread English or Russian before final acceptance and publication.
  • Regardless of the language of initial submission, ensure the writing is well-structured and comprehensive, with excellent cohesion and smooth transitions between ideas.

3. FORMAT AND LENGTH

  • Template: Authors must use the Generic PCAM Template for manuscript preparation.
  • File Format: Manuscripts must be submitted as LaTex files. Other file formats (e.g., doc., docx., PDF) are not acceptable for the main manuscript file.
  • Page Format: The PCAM template is formatted as a single-column page. Page margins, line spacing, font type, and font sizes are preset in the template. Authors should not alter these settings.
  • Main Body Sections: The main body of the manuscript (for most categories like Research Articles) must be strictly divided into four main sections, clearly labeled in bold letters: Introduction, Methods, Results, Discussion, and Conclusion.
  • Manuscript Length: While PCAM does not impose a strict page limit, for Research Articles and similar substantial contributions, the combined length of the main sections (Introduction, Methods, Results, Discussion and Conclusion) should be at least 5000 words. This word count excludes the Abstract, Keywords, Tables, Figures, References, Appendices.

4. STRUCTURE
