What is Systems Analysis

Systems analysis is also known as the "systems approach". With the overall optimization of the system as the goal, qualitative and quantitative analysis of all aspects of the system. It is a purposeful, step-by-step exploration and analysis process that provides decision makers with the information and data needed to directly judge and decide on the optimal system solution, thus becoming an important procedure and core component of systems engineering.

It has a wide range of applications and is generally used for the analysis of major and complex issues, such as the analysis and selection of policies and strategic issues, the development and design of new technologies, and the analysis of the input, processing and output of enterprise systems.

Main Steps:

1, a systematic description of the object of the study and the problem to be solved, with the aim of defining the objectives and describing the focus and scope of the problem;

2, the collection of information, on the basis of a systematic analysis of the interrelationships between the various factors through the analysis of the information, to seek a feasible solutions to the problem;?

3, according to the nature and requirements of the system, to establish a variety of mathematical models;?

4. Use mathematical models to compare and weigh the advantages and disadvantages of various options;?

5, determine the optimal program. Through the analysis, if you are not satisfied with the chosen solution, you can re-analyze the original steps. A successful systems analysis needs to be repeated many times on the various programs cycle and comparison, in order to find the optimal solution.
