  1. Subjective weight matrix: [0.1549, 0.133, 0.2127, 0.1944, 0.3047], objective weight matrix: [0.5941, 0.1166, 0.0916, 0.0536, 0.1441], bias parameter α=0.6; activity for day 1 was calculated as: 0.6 ×(0.15491+0.1331+0.21271+.19441+0.30471.003)+(1−0.6)×(0.59411+0.11661+0.09161+0.05361+0.14411.003)=1.0005
