+		// items with the same first union cannot be active at the same time), compute the usage for each (again,
+		// taking into account resource sharing), and take the maximum.
+		//
+		// Example:
+		// Let's have the following allocation items:
+		// ai1: sdid1, vrf1 - usage 5
+		// ai2: sdid2, vrf1 - usage 10
+		// ai3: sdid3, vrf2 - usage 15
+		// ai4: sdid1, vrf3 - usage 20
+		// ai5: sdid3, vrf1 - usage 25
+		// The following combinations of active allocation items are possible:
+		// 1) ai1, ai2, ai3
+		// 2) ai1, ai2, ai5
+		// 3) ai2, ai3, ai4
+		// 4) ai2, ai3, ai5
+		// Here is how we calculate the usage for combination 1:
+		// ai1 and ai2 contain the same resource union vrf1, so they share the resource - we take the max of usage,
+		// so we have:
+		// max(5, 10) + 15 = 25
+		// Similarly, we calculate the usage of the other combinations:
+		// 2) max(5, 10, 25) = 25
+		// 3) 10 + 15 + 20 = 45
+		// 4) max(10, 25) + 15 = 40
+		// So, the result in this case is:
+		// max(25, 25, 45, 40) = 45
+		//
+		// We might have a problem with this approach, if we have a lot of combinations. Assuming we have at most 2
+		// allocation items with the same resource union (sdid), the number of combinations would be
+		// 2 ^ n
+		// where n is the number of allocation items that have the same resource union (sdid). That would be
+		// the number of change orders currently in progress.
+		//
+		// Here is one optimization that we can do:
+		// If we have allocation items that have all resource unions the same, we don't need to generate combinations
+		// with each of them, we can just take the one of them with the maximum usage, as it is clear that the others
+		// will not lead to a bigger usage.
+		// For example, if we had the following allocation items:
+		// ai1: sdid1, vrf1 - usage 10
+		// ai2: sdid1, vrf1 - usage 20
+		// We only need to take the combinations with ai2, as they will always lead to bigger usage than the remaining
+		// combinations with ai1.
