“…Assuming: (a u,k-1 , a uk ) represents the normalized values of knowledge attributes V k-1 and V k (2 ≤ k ≤ b) of the u-th strategy of collaborative knowledge resource management; the horizontal axis V k-1 represents the value of a u,k-1 , and the vertical axis V k represents the value of a uk . Since a u,k-1 ∈ [0,1] and a uk ∈ [0,1], all points of (a u,k-1 , a uk ) are within a rectangle with [0,0], [0,1], [1,0], and [1,1] as vertices. Assuming l k-1 and l k respectively represent the arithmetic mean of the normalized values of knowledge attributes V k-1 and V k , then there is:…”
