Rule 2.3) Following the principle that MV i should be generally unchanged after one
period in an ideal case, x i can be determined by D, T, and f.
Note: e.g., for the 8
th AS, watching TV, assuming that the resident watches TV for
4 h (D 8 ), and sleeps 8 h (D 1 + D 2 ) per day (T 8 = 24 h), x 8 is determined by Eq. (2),
x 8 ¼
Norm MV
½T 8 À ðD 1 þ D 2 Þ À D 8 Š
:
ð2Þ
which means x 8 should increase by Norm_MV in the remaining 12 h, while it
decreases by Norm_MV during the 4 h (D 8 ).
Rule 2.4) MV i increases step by step if i = 7 or 11. For the 7
th AS, “going to toilet
(long duration)”, MV 7 increases by Norm_MV/(3 Â T 7 ) 2.5 h after the resident
starts eating. For the 11
th AS, “taking clothes out of the washing machine”, MV 11
increases by Norm_MV 1 h after the resident puts their clothe into the washing
machine.
Rule 3.1) MV i will decrease if the ith AS has been performed except if i = 13.
