The Human Operator Simulator. Volume IX. HOS Study Guide.
Abstract
In recent years, as 'systems' (whether spacecraft, jet fighters, or office equipment) have become more complex, there has been a growing concern about the extent to which these systems are adapted to the capabilities of the individuals who are called on to operate them. The methodology currently used to evaluate systems--building prototypes or testing designs in simulators--relies on the construction of real hardware that can be tested with real operators. This requirement inevitably means that there is a substantial time lag between the system's initial design and the time when the prototype can be built, tested, evaluated, and any proposed changes 'recycled' through the system design process. In addition, the use of dynamic simulators that use real operators inevitably requires a substantial outlay of money for the development of attendant hardware and software, for the training and retraining of operators. and for the performance, analysis, and evaluation of controlled experiments that utilize the simulators. The Human Operator Simulator (HOS) was developed to alleviate these problems in two ways. First, by enabling potential problem areas to be identified earlier in the system design process, HOS enables corrections to be made at lower cost and with less disruption of development schedules. Second, for areas of marginal operator performance, HOS can focus dynamic simulations on the likely sources of difficulty, reducing the time and cost required to validate system operability.
