Abstract: To solve the shared resource allocation problem in multi-project management,research on characters of enterprise resources under IT circumstances was done.And resource equivalent efficiency and efficiency conversion factor used in enterprise resource concurrent allocation were determined by virtue of stochastic theory.A model for resource allocation was proposed and a corresponding algorithm was presented with mathematical analysis.The model and algorithm were applied to give an example,which was analyzed to realize the rational resource allocation in enterprise multi-project management.

Key words: stochastic theory, multi-project management, resource allocation, equivalent efficiency, heuristic search algorithm
