Journal of Decision Support Systems and Multi-Criteria Decision Making (JODESMA) considers plagiarism and other forms of unattributed appropriation of intellectual work to be serious violations of publication ethics.

Plagiarism includes presenting another person's words, ideas, data, methods, results, figures, tables, or other intellectual contributions as one's own without appropriate attribution.

• Direct copying without quotation or appropriate attribution.
• Substantial paraphrasing without citation.
• Presenting another person's ideas or findings without acknowledgment.
• Reuse of previously published material without appropriate disclosure.
• Substantial overlap between manuscripts without adequate explanation.
• Self-plagiarism or inappropriate text recycling.
• Duplicate or redundant publication.

All submitted manuscripts may be screened for textual similarity or other indicators of inappropriate reuse. The journal may use recognized plagiarism or similarity-detection tools as part of its editorial quality-control process.

A similarity score alone does not automatically establish plagiarism. The editorial team considers the context, source material, type of overlap, extent of overlap, attribution, and disciplinary conventions before making an editorial determination.

Minor issues identified before publication may require clarification, citation, rewriting, or correction.

Substantial or deliberate plagiarism may result in rejection of the manuscript and may lead to further investigation when appropriate.

If plagiarism is identified after publication, Journal of Decision Support Systems and Multi-Criteria Decision Making (JODESMA) may publish a correction, expression of concern, or retraction depending on the severity and effect of the problem.

Authors are responsible for ensuring that their manuscripts appropriately acknowledge the work of others and that all sources are accurately cited.

The plagiarism policy applies to manuscripts, figures, tables, datasets, supplementary materials, and other forms of intellectual content submitted for publication.
