With the increase of new product manufacture order of aviation steering gear, multi-project resource conflict has become the serious problem of production order delivery. Based on the analysis of the characteristics of new product manufacture processing of aviation steering gear and the resource conflict, this article uses the method of Pert plan review method for reference, builds digestion model aiming to deal with new product manufacture resource conflict problem of aviation steering gear, tries to identify resource conflicts before they happen, after classifying resource conflict then deals with them, in order to achieve using the multi-project management thoughts to reasonably achieve the production scheduling goal. Finally, through the production instance, this paper verifies the rationality and validity of the resource conflict digestion model.
