Disease simulation system and method

A system for predicting an effect of patient self-care actions on a disease control parameter such that a future disease control parameter value X(t.sub.j) at time t.sub.j is determined from an actual disease control parameter value A(t.sub.i) at time t.sub.i based on an optimal control parameter value R(t.sub.j) at time t.sub.j, the difference between said actual disease control parameter value A(t.sub.i) and an optimal control parameter value R(t.sub.i) at time t.sub.i, and a set of differentials between patient self-care parameters having patient self-care values S.sub.M (t.sub.i) at time t.sub.i and optimal self-care parameters having optimal self-care values O.sub.M (t.sub.i) at time t.sub.i, said differentials being multiplied by corresponding scaling factors K.sub.M, said system comprising:
