Resource delivery method and device, computer equipment and storage medium

The invention relates to a resource delivery method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring invoice data of a plurality of data sources, extracting amount information from the invoice data, establishing a form to store a corresponding relationship between the amount information and the data sources, calculating an index value of each data source according to a plurality of preset index calculation models and the form, acquiring a credible value of each data source, taking the index value and the credible value as attribute values of a data source, taking the credible value as a label, taking the index value as a sample value, training a preset decision tree model to obtain a trained decision tree model, establishing a target function, and establishing a constraint condition according to a value interval of a data source amount growth rate and a resource release amount, and carrying out the solving by adopting a particle swarm algorithm.
