Workshop goals l.jpg
Workshop Goals

  • The purpose of the workshop is to share project progress and to generate ideas for future development.  

  • This is NOT a user’s meeting; but rather, it is an opportunity to discuss the current status and future plans for the IMPRINT Tool and supporting research.

Slide5 l.jpg

Tool Development


  • Evolving analysis demands

    • Support System of Systems Analyses

    • Support analysis of joint operations

    • Represent human behavior in network simulation

    • Consider alternative maintenance concepts

      (e.g. increased crew maintenance)

  • Decrease barriers to usage

    • Bi-modal set of users

    • User interface too broad and deep with addition

      of new features

    • Encourage valid analyses

    • Information assurance constraints (i.e. security)

    • Maintain platform compatibility

  • Package more human factors R&D results

  • Merged VACP, Goal and Advanced workload and network modules

  • Crew Chief maintenance & animation

  • New Graphical User Interface

  • .NET Framework

  • Sophisticated users – links to other sims

Slide11 l.jpg

IMPRINT: Development

  • Enhanced IMPRINT maintenance modeling

    • Improved the fidelity of modeling direct support maintenance

    • Increased capacity to model maintenance of complex systems (more components, systems, tasks) and more of those systems with longer scenarios

    • integrated transition between operator and maintainer analyses such that maintainability variables will directly impact operational system effectiveness.

  • Developed concepts and prototypes for IMPRINT ver. 8 (two products, Standard and Pro)

  • Investigated the validity and robustness of dynamic human task scheduling constructs such as the WinCrew strategies, information processing/process control theory (IP/PCT), and goal oriented behavior modeling.

  • Mapped IMPRINT taxons to skills and abilities in SkillsNET objects (thru Navy’s SEAPRINT program)

Updating imprint stressors l.jpg



Updating IMPRINT Stressors

Options for Incorporating Changes to Performance Shaping Functions

    • Requires new release

  • B. Input new algorithm using “custom stressor” feature

    • No change to source code

    • User defined models only

  • C. Use IMPRINT variables, beginning and ending effects

    • No change to source code

    • User defined models only

    • Greater user skill required

  • D. External Model Calls to more complex models

    • User defined models only

    • Greater user skill required
