  • Modeling Methodology
  • Model Execution
  • Random numbers and objects
  • Experiment design and simulation analysis
  • Verification, validation, and accreditation of models
  • Interplay between other areas of computer science and simulation
  • Advanced Applications

Publication policies

The ACM Publications Policies page addresses issues of plagiarism, copyrights, simultaneous submissions, etc. Please pay special attention to ACM Author Representations Policy.

ACM strongly encourages, and soon will require, that all authors have registered for their own ORCID, and have obtained their unique researcher identifier. For more information, see

Please consult the Policy on Authorship of the ACM.

Types of submissions

TOMACS accepts manuscript submissions in these categories:

  • Methodological research: Innovative modeling and simulation methods. It should be clearly demonstrated how the new methodological developments advance the current state of the art of modeling and simulation.
  • Application driven research: Mature applied work with a clear impact on modeling and simulation. The work should advance the state of the art in modeling and simulation in general, or the use of modeling and simulation in a specific application area, e.g., by gaining new insights into the process of validation, verification and accreditation in a specific field, revealing limitations of current methods and propelling thus new methodological developments in modeling and simulation. Please note: using known simulation techniques or software to study a specific problem is not sufficient for a TOMACS paper. Articles whose main contribution applies to a given application are better suited for a journal devoted to that application area.
  • Review articles: Thorough and topical synthesis of an area of research. Reviews should provide a structured overview about and revealing new insights into a field, thereby combining and synthesizing different perspectives. Reviews can refer to methodological developments as well as to best practice of modeling and simulation in specific application fields


  • Documents should follow the ACM formatting guidelines. Because TOMACS has page count constraints, authors are encouraged to keep the presentation concise. Papers should not be longer than 25 pages. Also, it may be appropriate to place content in supplementary electronic material to accompany the submission, e.g. information and software required for reproducing the results presented in the paper. If the paper is accepted, paper and supplementary material will be made available in the ACM Digital Library.
  • Language Services

    • ACM has partnered with International Science Editing (ISE) to provide language editing services to ACM authors. ISE offers a comprehensive range of services for authors including standard and premium English language editing, as well as illustration and translation services, and also has significant international outreach, especially in China. Editing is available for both Word and LaTeX files. As an ACM author, you will receive a generous discount on ISE editing services.

      To take advantage of this partnership, visit  (Editing services are at author expense and do not guarantee publication of a manuscript.)

      Please note that formatting assistance is provided at no charge to authors by Aptara, as specified on the author style guide page:

Submission process

TOMACS accepts submissions electronically via Manuscript Central. Authors should create an account and password, login selecting "Transactions on Modeling and Simulation", and proceed to the Author Center to submit a manuscript, the supplementary material, and the cover letter. The cover letter should be no longer than one page and should:

  • concisely summarize why your paper is a valuable addition to the modeling and simulation field, particularly referring to modeling and simulation methods (see charter of TOMACS);
  • briefly relate your study to previously published work;
  • specify the type of article you are submitting (see Types of Submissions);
  • suggest appropriate TOMACS Associated Editor(s) to handle your manuscript (or, in the case of Special Issues, simply indicate the name of the special issue);
  • list at least two recommended reviewers (with whom you have not co-authored a paper within the last three years), including potentially opposed reviewers.
  • include, in the case of Special Issues, all information requested by the guest editors as an appendix in the cover letter.

TOMACS aims to improve the reproducibility of modeling and simulation research. Therefore, please include sufficient information to document the core steps of your scientific process as transparent as possible, e.g., data, model, experiment settings, including methods and configurations, and/or software.  Associate editors and reviewers will be asked to assess the paper also with respect to this information. Thus, although not required, submitted manuscripts which provide clear information on how to generate reproducible results, whenever possible, will be considered favorably in the decision process by reviewers and the editors. Please feel free to use the supplemental material for doing so.

If you are interested in taking part in the reproducing computational results (RCR) activity in TOMACS, please indicate this in your cover letter. Also please indicate which badges you would like to apply for, e.g., artifacts evaluated (functional), artifacts evaluated (reusable), artifacts available, and results being replicated. In addition, if you do not submit your paper to a special issue, select the category "Regular paper for the RCR Initiative" when submitting the paper. 

For submitting the material please follow the submission guidelines for the RCR initiative given below.  An independent reviewer will check whether all results presented in your paper can be reproduced and, in case of acceptance and successful reproduction of research results, your paper will be branded as such and advertised at the TOMACS web page.

Please see for more details on the different types of additional evaluation and branding ACM (incl. TOMACS) offers for its papers the policy Result and Artifact Review and Badging. If you have further questions please do not hesitate to contact the editor in chief.

Review process

The reviewing and publishing process in TOMACS is similar to that of other ACM Transactions; e.g., the reviewing process comprises the following steps.

  • An administrative assistant first checks the submission for completeness and notifies the Editor-in-Chief.
  • The Editor-in-Chief then determines if the paper is appropriate for consideration by TOMACS and, if so, assigns it to an Associate Editor.
  • The Associate Editor reads the paper and further determines if it is appropriate for TOMACS consideration, and if so, selects several referees.
  • The referees read the submission and measure its novelty, impact and correctness, and each returns a review to the Associate Editor.
  • The Associate Editor collects the reviews and makes a recommendation to the Editor-in-Chief on the acceptability of the submission.
  • The Editor-in-Chief, based on the reviews and Associate Editor's recommendation decides on the acceptability of the submission, and communicates the decision together with the Associate Editor's comments and referees reviews to the author.
  • For papers on which the Editor-in-Chief has a conflict, the role of Editor-in-Chief is assigned to a Past-Editor-in-Chief.
  • In case of a paper taking part in the replicating computational results activity - RCR , the associate editor and the editor in chief will assign a reviewer to the paper. This reviewer will get in contact with the authors to replicate the results of the paper and to evaluate the artifacts according to the badges the authors have applied for. This activity will take part independently of the usual reviewing process typically when the paper has been accepted or is close to being accepted. If the paper is accepted and the research results could be successfully replicated, a short report will be published alongside the original paper (as online suplement) and the paper will be assigned one or several of the ACM reproducibility badges. For facilitating the replication of the computational results and the evaluation of the artifacts the authors should follow the submission guidelines given below. 

Submission guidelines for RCR Initiative

Please note that the RCR initiative is an open reviewing process in which both reviewers and authors are known to each other. The RCR reviewing will start typically after the research paper has been or is close to being accepted.  To support an efficient replication of computational results and evaluation of artifacts, please follow carefully the following guidelines:

  • Indicate in the readme file, which artifacts are associated with the paper, e.g., software, data, and simulation models. Please provide detailed information about the required environment in which the artifact(s) can be executed and evaluated.
  • For software also give instructions to install compilers/interpreters and resolve dependencies if required.
  • Provide a script for every figure or table of the paper that contains results that shall be replicated.
  • For performance experiments additional scripts are required that record the time in a text file and describe your execution platform in detail. 
  • Please submit the above information, plus scripts, plus artifacts, plus any other information you find helpful in replicating the computational results and evaluating the artifacts as supplementary material. 
  • Please also provide information about the license of all artifacts provided.

Once accepted

In an effort to ensure efficient and accurate publication of accepted papers, we request that authors of accepted papers carefully follow these instructions.

  • Obtain Third-party Material Permissions:
    NOTE: If you have material owned by a third party, you must secure permission for its use before publication can proceed. If this is the case, please carefully read the guidelines at and:
    • Obtain written permissions from the copyright holders.
    • Add the appropriate attributions to the figure captions in your paper (giving credit to the copyright holder).
    • Include the source of the third-party material in the references.

  • Early Online Publication:
    • TOMACS publishes articles online first. This implies that all papers, once the author proofs have been processed by the publisher, will be added without delay to the ACM Digital Library.

Author Rights

Working with the computing community, ACM leadership has responded to calls to make scholarly articles more openly accessible, to enable authors to exercise greater control of their published works, and to comply with the increasing demands placed on authors by funding agencies. 

ACM authors now have three ways to manage their publication rights with ACM:

  1. A license granting ACM non-exclusive permission to publish—by choosing to pay for perpetual open access from the ACM Digital Library, authors may opt to self-manage all rights to their work. 
  2. A new Publishing License Agreement granting ACM exclusive publication rights—in choosing this license authors grant ACM the right to serve as the exclusive publisher of their work and to manage ongoing rights and permissions associated with the work, including the right to defend it against improper use by third parties. This exclusive license is roughly the equivalent of ACM’s traditional Copyright Transfer Agreement except that the author continues to hold copyright. 
  3. ACM's traditional Copyright Transfer Agreement—for authors comfortable with the existing agreement.

ACM is also implementing changes to to allow for more free access to the content of ACM journals and Special Interest Group conference proceedings in the ACM Digital Library and other online venues:

  • SIGs may choose to enable open access to the most current proceedings volume of their sponsored conferences from the conference or SIG site.
  • SIGs may make conference proceedings freely available via the ACM DL platform for up to two weeks before the event, and for a total of one month.

These options will facilitate access to proceedings content by conference attendees. They will also enable the community at large to learn about the latest developments as they are presented at the conferences.

Authors can post an Author-Izer link enabling free downloads of the Definitive Version of the work permanently maintained in the ACM Digital Library.

ACM Computing Classification System (CCS)

An important aspect of preparing your paper for publication by ACM Press is to provide the proper indexing and retrieval information from the ACM Computing Classification System (CSS). This is beneficial to you because accurate categorization provides the reader with quick content reference, facilitating the search for related literature, as well as searches for your work in ACM's Digital Library and on other online resources.
