| 摘要 |
The invention concerns a system for simulating an activity process which system comprises a model for illustrating the momentaneous status of the activity process having means for representing one or more activity units (100, 101), means for establishing a preexisting condition (301-306, 401-404), means for changing the existing condition (501, 502, 600), means for indicating at least the present levels of a first, a second and a third variable attributed to said activity unit (200, 201, 203), and means (307) for indicating a predetermined value on said means for establishing a preexisting condition and on said means (601) for changing the existing condition the system also comprises output means (800) for producing a resulting status at, at least one, determined point of time in the simulation process. |
