Systems information measurement

In systems there are three key factors(Materials,Energy,and Information,MEI),in which exist some difficulties and arguments about the quantitative measurement of information.conceptionally,information quantity should be divided into two kinds,Matter Information Quantity(MIQ)-bit and Distance of Information-state Transition(DIT).The problem of 1 from N for the former MIQ is the difference degree of one state among N different states,while the problem of 1 from N for the latter DIT is the distinction of one state from N different states.The MIQ is the measurement for the static difference degree,and the DIT is the measurement for the dynamic process of the distinction(differenciation).In the quantity measurement,a calculation method system for information measurement was given,which concerns Whole Information Quantity(WIQ),Target Information Quantity(TIQ),Realizability,DIT,Mean DIT,Cost of Information-state Transition(CIT),CIT per bit,etc.Some examples were given,such as the simplicity and quickness of the search of information and knowledge,the convenience of management operations,as well as the easiness of control,etc.Finally,the exchange of DIT for various resources was explained with an example,and then the feasibility of increasing the wealth was also explained.
