The invention relates to the technical field of
data processing, in particular to a cost
management system for multi-
project engineering, which comprises an acquisition module, a judgment module, a determination module, a sorting module, an adjustment module and an output module. According to the method, various key data in the
project implementation process are collected in real time, and the temporary project is judged through the total cost deviation; calculating a sub-item deviation formed by two key costs of
consumables and manpower, and analyzing the fluctuation of the sub-item deviation in a
time sequence to determine a target item; finally, a project
list is obtained by combining deviation dominant type judgment and multi-dimensional comprehensive sorting, and meanwhile, a threshold value is dynamically adjusted according to historical data, so that the
system can adapt to various actual conditions; the problems of low recognition accuracy and recognition lagging of projects with abnormal cost caused by excessive dependence on
static data and incapability of adapting to variable actual projects are effectively solved.
