modified. Fortunately, we have both the experienced personnel and the technological capacity to construct a Manpower System, exercise it, and train personnel by it. We do not have to accept partial fulfillment from the testing of one or another minuscule model when complete fulfillment from the testing of the entire Manpower System is available. We therefore propose that these two models of Illness and Health be accepted as a basis for the logical programing of a computer-based Manpower System; specifically, the Health Manpower Subsystem. Design of an appropriate system will require empirical research to tie down each proposition in the computer program. Programing will permit simulation of these two models within the comprehensive H e a 1 t h Manpower Subsystem. With simulation, we can modify parameters (e.g., Illness, Health, the Public, closure, ratios, and so forth) and determine their consequences; e.g., how Social Security or the Engineering Manpower Subsystem affects health manpower. Furthermore, the simulation will provide a vehicle by which to train personnel for functions appropriate to health which we cannot now predict or comprehend. In summary, because neither illness nor health respects the closure offered by artificial boundary lines, a computer-based system for health manpower simulation may very well become the entering wedge toward a comprehensive, world perspective on manpower.
