Improved Performance Research Integration Tool

<h2 id="history">History</h2>
The IMPRINT tool grew out of manpower, personnel, and training (MPT) concerns identified in the mid-1970s by the U.S. Air Force, Navy, and Army. The U.S. Navy first developed the HARDMAN Comparability Methodology (HCM), with HARDMAN being a <a href="/facts/Portmanteau/d124JEbz">portmanteau</a> of hardware and manpower. The Army then tailored the manual HCM, which became known as HARDMAN I, for application to a broad range of weapon systems and later developed an automated version, HARDMAN II.<a class="footnote-ref" id="fnref:6" href="#fn:6">6</a> HARDMAN II.2 was first released by the Army Research Institute (ARI) in 1985. It required a <a href="/facts/VAX-11/prkm7jvA">VAX-11</a> computer to host its suite of analytical processes. An upgraded version was released in 1990.
In HARDMAN I and II, there was no direct link between MPT and performance. To directly remedy this shortcoming, the U.S. Army began the development of a set of software analysis modules in the mid-1980s.<a class="footnote-ref" id="fnref:7" href="#fn:7">7</a> This set of modules was called HARDMAN III, and although the name was the same, it used a fundamentally different approach for addressing MPT concerns than previous methods by providing an explicit link between MPT variables and soldier–system performance.<a class="footnote-ref" id="fnref:8" href="#fn:8">8</a> Software development was done by Micro Analysis and Design (MA&D). 
HARDMAN III was a major development effort of the Army Research Institute's (ARI) System Research Laboratory. The contract that supported the work was let in a three-phase development process.<a class="footnote-ref" id="fnref:9" href="#fn:9">9</a> HARDMAN III was government-owned and consisted of a set of automated aids to assist analysts in conducting MANPRINT analyses. As PC DOS-based software, the HARDMAN III aids provided a means for estimating MPT constraints and requirements for new weapon systems very early in the acquisition process. The DOS environment imposed several limitations on the HARDMAN III tool set. The most significant problem was the 640K <a href="/facts/RAM/DuD4bxh6">RAM</a> limitation; the original HARDMAN III tools were designed for pieces of analyses to fit within these RAM blocks. RAM constraints led to a restriction of 400 operations tasks and 500 maintenance tasks.
The nine modules in HARDMAN III were:

<ol><li>Manpower-based system evaluation aid (MAN-SEVAL), which was used to assess human workload</li>
<li>Personnel-based system evaluation aid (PER-SEVAL), which was used to assess crew performance in terms of time and accuracy</li>
<li>System performance and RAM criteria estimation aid (SPARC), which helped Army combat developers identify comprehensive and unambiguous system performance requirements needed to accomplish various missions</li>
<li>Manpower capabilities analysis aide (MANCAP), which helped users estimate maintenance man-hour requirements at the system unit level</li>
<li>Human operator simulator (HOS), which was used to develop improved estimates for task time and accuracy</li>
<li>Manpower constraints aid (M-CON), which Identified the maximum crew size for operators and maintainers and the maximum Direct Productive Annual Maintenance Manhours (DPAMMH).</li>
<li>Personnel constraints aid (P-CON), which estimated the significant personnel characteristics that described and limited the capabilities of the probable soldier population from which the new system's operators and maintainers would come</li>
<li>Training constraints aid (T-CON), which was designed to be used by the government to identify the types of training programs that were likely to be available to support new systems</li>
<li>Force analysis aid (FORCE), which provided an Army-wide assessment of manpower and constraints based on estimating numbers of people and impacts by types of people (such as <a href="/facts/ASVAB/rsyFtRdc">ASVAB</a> score and <a href="/facts/United_States_military_occupation_code/tKKIhYMm">MOS</a>)</li></ol>
IMPRINT was originally named: Integrated MANPRINT Tools and was first released in 1995. It was a Windows application that merged the functionality of the 9 HARDMAN III tools into one application. In 1997 IMPRINT was renamed to the Improved Performance Research Integration Tool – the name changed but the IMPRINT acronym remained the same. Between 1995 and 2006 several enhancements were made to IMPRINT and new releases (Versions 2 through 6) were made available. IMPRINT Pro was introduced in 2007. It featured a new interface design and complete integration with the <a href="/facts/Micro_Saint_Sharp/8qfpKeCC">Micro Saint Sharp</a> simulation engine. It had enhanced analytical capabilities and moved from being an Army tool to a tri-service tool. From the beginning IMPRINT has continued to evolve, new enhancements have been continually added, and new releases made freely available to the user community. IMPRINT has over 800 users supporting the Army, Navy, Air Force, Marine, NASA, DHS, DoT, Joint, and other organizations across the country.

<h2 id="discrete-event-simulation-in-imprint">Discrete event simulation in IMPRINT</h2>
Simulations, or Missions as IMPRINT refers to them, contain a task network called a Network Diagram. The network diagram contains a series of tasks connected by paths that determine control flow. System objects called entities flow through the system to create a simulation. IMPRINT also includes more low level features such as <a href="/facts/Global_variables/XWF9zC08">global variables</a> and <a href="/facts/Subroutines/9vFJrg0A">subroutines</a> called macros.<a class="footnote-ref" id="fnref:10" href="#fn:10">10</a>

<h3>Tasks</h3>
The task node is the primary element driving the simulation's outcome. Task nodes simulate system behavior by allowing programmer-specified effects, task duration, failure rates, and pathing. Task Effects are programmer-specified C# expressions where programmers can manipulate <a href="/facts/Variable_(computer_science)/VoCKtwml">variables</a> and <a href="/facts/Data_structures/yNsNvL1I">data structures</a> when a task is invoked. Task duration can be specified by the programmer as a specific value, through a <a href="/facts/Probability_distribution/EpsKKVRu">probability distribution</a>, or using a C# expression. Programmers can also specify task success in a similar way. Task success influences the effects of the task node and the pathing of the entity. Failure consequences include task repetition, task change, and mission failure among other options. Control flow and pathing can also be specified by the programmer. IMPRINT provides a series of other nodes that include special functionality:
Nodes include:

<ul><li>Start Node: Emits the first entity in the model, signifying the start of a simulation execution.<a class="footnote-ref" id="fnref:11" href="#fn:11">11</a></li>
<li>End Node: Receives an entity that signifies the end of the simulation.<a class="footnote-ref" id="fnref:12" href="#fn:12">12</a></li>
<li>Goal Node: Emits an entity when a specified goal is achieved, activating a secondary task network.<a class="footnote-ref" id="fnref:13" href="#fn:13">13</a></li>
<li>Work Load Monitor: A visual node not connected to the task network that displays the workload value and number of active tasks associated with a specific Warfighter.<a class="footnote-ref" id="fnref:14" href="#fn:14">14</a></li>
<li>Function Node: creates a subnetwork diagrams which allow users to modularize complex networks into specific tasks.<a class="footnote-ref" id="fnref:15" href="#fn:15">15</a></li>
<li>Scheduled Function Node: a Function node that allows the user to specify clock times for the start and end of the execution of the subnetwork tasks.<a class="footnote-ref" id="fnref:16" href="#fn:16">16</a></li></ul>
<h3>Entities</h3>
Entities are dynamic objects which arrive into the system and move through the task network. Entities flow from one task to the next based on the task's path logic. When an entity enters a task, the task's effects are triggered. When the task concludes, the entity moves to the next task. One entity is generated by default at the beginning of the simulation. More entities can be generated at any point in the simulation based on programmer specified logic. When all entities reach the end node or are destroyed, the simulation concludes.<a class="footnote-ref" id="fnref:17" href="#fn:17">17</a>

<h3>Events</h3>
Events are occurrences that happen in an instant of simulated time within IMPRINT that change the global state of the system. This can be the arrival or departure of an entity, the completion of a task, or some other occurrence. The events are stored in a master event log which captures every event that will happen and the simulated time that the event occurred. Due to the stochastic nature of discrete-event simulation, an event will often trigger the generation of a random variate to determine the next time that same event will occur. Thus, as events occur, in the simulation, the event log is altered.<a class="footnote-ref" id="fnref:18" href="#fn:18">18</a>

<h3>Control flow</h3>
Once a task concludes, the invoking entity moves to another node which is directly connected to the current node in the task network. Nodes can connect to any number of other tasks, so IMPRINT provides a number of pathing options to determine the task to which the entity moves.<a class="footnote-ref" id="fnref:19" href="#fn:19">19</a>

<ul><li>Probabilistic pathing allows the programmer to specify a percentage chance for an entity to be moved adjacent nodes by inputting the exact probabilities, summing to one hundred, for each node.<a class="footnote-ref" id="fnref:20" href="#fn:20">20</a></li>
<li>Tactical pathing allows the programmer to use C# predicates to determine the pathing of an entity to each adjacent node. If more than one expression evaluates to true, the entity will follow the first path with a true expression.<a class="footnote-ref" id="fnref:21" href="#fn:21">21</a></li>
<li>Multiple pathing behaves exactly like tactical pathing but will path entities to any adjacent node with an expression evaluating to true.<a class="footnote-ref" id="fnref:22" href="#fn:22">22</a></li></ul>
<h3>Variables and macros</h3>
IMPRINT has a number of global variables used by the system throughout a simulation. IMPRINT provides the public global variable Clock which tracks the simulation's current time. IMPRINT also has private variables such as operator workload values. IMPRINT allows the modeler to create custom global variables that can be accessed and modified in any task node. Variables can be of any type native to C#, but the software provides a list of suggested variable types including C# <a href="/facts/Primitive_data_types/0c898228">primitive data types</a> and basic data structures. IMPRINT also provides the programmer with the functionality to create globally accessible subroutines called macros. Macros work as C# functions and can specify <a href="/facts/Parameter_(computer_programming)/LcuLbbSq">parameters</a>, manipulate data, and return data.<a class="footnote-ref" id="fnref:23" href="#fn:23">23</a>

<h2 id="human-performance-modeling">Human performance modeling</h2>
IMPRINT's workload management abilities allow users to model realistic operator actions under different work overload conditions.<a class="footnote-ref" id="fnref:24" href="#fn:24">24</a> IMPRINT allows users to specify Warfighters which represent human operators in the modeled system. Each task in IMPRINT is associated with at least one Warfighter. Warfighters can be assigned to any number of tasks, including tasks that execute <a href="/facts/Concurrency_(computer_science)/Ctnrrq4A">concurrently</a>.<a class="footnote-ref" id="fnref:25" href="#fn:25">25</a> IMPRINT tasks can be assigned VACP workload values.<a class="footnote-ref" id="fnref:26" href="#fn:26">26</a> The VACP method allows modelers to identify the <a href="/facts/Visual/QVcuA27K">visual</a>, <a href="/facts/Hearing_(sense)/EPYrVkSx">auditory</a>, <a href="/facts/Cognitive/ga0tSBul">cognitive</a>, and <a href="/facts/Psychomotor_learning/GefG0GqG">psychomotor</a> workload of each IMPRINT task. In an IMPRINT task, each resource can be given a workload value between 0 and 7, with 0 being the lowest possible workload, and 7 being the highest possible workload for that resource. The VACP scale for each resource provides <a href="/facts/Methods_of_neuro-linguistic_programming/c0nQxIJM">verbal anchors</a> for certain scale values. For instance, a visual workload of 0.0 corresponds to "no visual activity", while a visual workload of 7.0 continuous visual scanning, searching, and monitoring.<a class="footnote-ref" id="fnref:27" href="#fn:27">27</a> When a Warfighter is executing a task, their workload is increased using the VACP value assigned to that task. An IMPRINT plugin module was proposed in 2013 to improve the cognitive workload estimation within IMPRINT and make the overall calculation less linear.<a class="footnote-ref" id="fnref:28" href="#fn:28">28</a> IMPRINT's custom reporting feature allows modelers to view the workload over time of the Warfighters in their models. Workload monitor nodes allow modelers to view the workload of a specific Warfighter as the simulation executes.<a class="footnote-ref" id="fnref:29" href="#fn:29">29</a>
