The invention relates to the technical field of
data analysis, and discloses a business analysis and decision support method and
system, and the method comprises the steps: collecting purchase-related
business data from a plurality of data sources, and carrying out the preprocessing; storing the preprocessed data in a centralized
data warehouse, and performing management based on a preset
data governance strategy; performing multi-
dimensional analysis on the structured data based on a
statistical analysis model and a
machine learning
algorithm, and generating a key performance indicator KP I and a
trend prediction result; providing a customized visual display interface according to a
user role, and presenting the KP I and a
trend prediction result through an interactive instrument panel; and generating a purchase optimization suggestion based on the analysis result, evaluating the influence of different purchase strategies through analogue
simulation, and outputting corresponding decision support information. The
system effectively solves the problems of weak analysis capability, insufficient decision support and the like in an existing purchase
decision system, and is suitable for multiple application scenes such as enterprise purchase management and the like.
