The general abstract system, such as a social system, economic system, agricultural system, ecological system, education system, etc., involves many different kinds of factors. It is the result of the mutual interactions of these factors that determines the development tendency and the behavior of the system. It is often the case that among all the factors, the investigators want to know which ones are primary and which ones are secondary; which ones have dominant effect, while others exert less influence, on the development of the system; which factors motivate the positive development of the system so that these factors should be strengthened; which ones constitute obstacles for the desirable development of the system so that these factors should be weakened ... For instance, for the overall performance of an economic system, there are generally many influencing factors. In order to realize the desire of producing additional output with less input, the necessary systems analysis needs to be done carefully.
