equired for an occupation (Ruck, 1982). It includes procedures for developing data bases
and modeling the dynamic flow of people through jobs and through both formal training and
on-the-job training. Furthermore, the system includes modeling and optimization capabilities
which provide estimates of training quantities, costs and capacities for both formal training
and training on-the-job training (Vaughan, et al., 1989).
Problem - MPT Decisions in the New Weapon Systems Acquisition Process
In the New Weapon Systems Acquisition Process (NWSAP), the assessment of changes
required in manpower, personnel, and training programs are difficult (Gentner, 1988) - the
problem is particularly acute for the largely-hidden on-the-job training (OJT) costs and OJT I
capacity of units which will receive the new system. The TDS, with its capability to estimate .
such costs and capacities, may be of considerable value in helping evaluate MPT costs and
capacities in NWSAP studies, if TDS procedures can be adapted to predict needed task
charactersitics and to model expected impacts on job and training patterns.
TDS Training-Time Models
Training-time models are important components of the TDS data base. These models
may be thought of as learning curves; they translate training time on a group of tasks (task
module) into the proficiencv, relative to full proficiency, obtained from such training. Figure
1 illustrates a set of training-time models for an aircraft maintenance task. Note that
separate learning curves were developed for several major training settings or training
delivery methods, including classroom, correspondence course, guided hands-on, and OJT.
These training-time models permit different training delivery methods to be traded off to
find the best way, or combination of ways, to deliver training for a particular task. These
training-time models play a critical role in the TDS model. In particular, they are the basis
for estimating OJT training quantities.
