|
The scenario from example 1 and example 2 is presented again, with the 3 transmitters and the same coverage, where the calculation magnitude is units of the point layer, with one unit at each point, the weight is equal to 1 for both, the minimum and maximum are calculated automatically (in this example, the minimum is selected as 0 and the maximum as 5), and the saturation is infinite. However, in this case, we assign the following priorities: Tx1 equals 1, Tx2 equals 3, and Tx3 equals 1 (we give higher priority to Tx2).
The process in this scenario would be as described below.
ITERATION 1 Step 1: Analyze coverage Target coverage: Points A, B, C, D, E, F, G (7 units). Tx1 coverage: Points A, B, C, D, E (5 units). Tx2 coverage: Points E, F (2 units). Tx3 coverage: Points A, B, F, G (4 units). Step 2: Score and choose the prioritized transmitter Factors that may modify the score: •The weight of the layer for units is 1, so the scores do not change. •By default, the multipliers are set to 1 and the additions to 0, so the scores do not change. •Tx2 has higher priority than Tx1 and Tx3, so the scores will have to be weighted. Individual scores are awarded: P(Tx1) = 5/5 = 1 P(Tx2) = 2/5 = 0.4 P(Tx3) = 4/5 = 0.8 The scores are weighted by multiplying them by their individual priority: PPrioritized(Tx1) = 1*1 = 1 PPrioritized(Tx2) = 0.4*3 = 1.2 PPrioritized(Tx3) = 0.8*1 = 0.8 Scores are normalized by dividing by the highest priority: PNormalized(Tx1) = 1/3 = 0.333 PNormalized(Tx2) = 1.2/3 = 0.4 PNormalized(Tx3) = 0.8/3 = 0.267 Tx2 is chosen because it has the highest score after weighting and normalization. Step 3: Remove coverage provided by the chosen transmitter from the target coverage Since Tx2 covered points E and F, the coverage of the other transmitters is updated by removing those points.
ITERATION 2 Step 1: Analyze coverage Target coverage: Points A, B, C, D, G (5 units). Tx1 coverage: Points A, B, C, D (4 units). Tx3 coverage: Points A, B, G (3 units). Step 2: Score and choose the prioritized transmitter Individual scores are awarded as follows: P(Tx1) = 4/5 = 0.8 P(Tx3) = 3/5 = 0.6 The scores are weighted by multiplying them by their individual priority: PPrioritized(Tx1) = 0.8*1 = 0.8 PPrioritized(Tx3) = 0.6*1 = 0.6 Scores are normalized by dividing by the highest priority: PNormalized(Tx1) = 0.8/3 = 0.267 PNormalized(Tx3) = 0.6/3 = 0.2 Tx1 is chosen as it has the highest score after weighting and normalization. Step 3: Remove coverage provided by the chosen transmitter from the target coverage Since Tx1 covered points A, B, C, and D, the coverage of the other transmitters is updated by removing those points.
ITERATION 3 Step 1: Analyze coverage Target coverage: Point G (1 unit). Tx3 coverage: Point G (1 unit). Step 2: Score and choose the prioritized transmitter Individual scores are awarded as follows: P(Tx3) = 1/5 = 0.2 The scores are weighted by multiplying them by their individual priority: PPrioritized(Tx3) = 0.2*1 = 0.2 Scores are normalized by dividing by the highest priority: PNormalized(Tx3) = 0.2/3 = 0.067 Tx3 is selected.
FINAL RESULT (SORTED BY SCORE) Tx2 covers 2 units and obtains a score of 0.4. Tx1 covers 4 units and obtains a score of 0.267. Tx3 covers 1 units and obtains a score of 0.067. |
