  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 ×(0.1549∗1+0.133∗1+0.2127∗1+.1944∗1+0.3047∗1.003)+(1−0.6)×(0.5941∗1+0.1166∗1+0.0916∗1+0.0536∗1+0.1441∗1.003)=1.0005
