Major problems
1. Minimal dissipation processes .
2. Stationary state of an open system that includes intermediary.
3. Intermediary’s limiting possibilities in close, open and non-stationary macro systems.
4. Qualitative measure of irreversibility in microeconomics.
5. Realizability area of macro system.

If g = 0, qij = ij(Ti – Tj), then
If m = 2, T1 = T+, T2 = T–, then
For g = AX Prigogine’s extremal principle holds for
any u (A – Onsager matrix).

Optimal processes
Availability Amax()=?
Control u(t) = (u1, …, um),
h(t) = (h1,…,hm), hi = {0, 1}
k – number of conditions on final state.
StatementsStatements::
1. .u*(t) h – are minimal dissipation processes,
2. For reservoirs {u*(t), h*(t)} are piece-wise constant
function that takes not more than k+1 values.
3. System’s entropy is piece-wise linear function q, g
