Current inventory planning in the National Aeronautics and Space Administration (NASA) has required the development of efficient methods to project resource procurements. This paper addresses a specific type of resource analysis and its implementation in an interactive computer system environment. This type of analysis is described as a multi-resource/multi-project (MR/MP) model. The emphasis of this article is towards two aspects of the solution process. The first involves an efficient approach for inputting the problem characteristics into the computer data base. The second addresses the scheduling procedure and analysis used for minimizing resources. Both represent important parts of the end-to-end resource utilization problem. Solution is accomplished with an interactive man/machine system. Descriptions of the database operations and example outputs from the program are presented. A comparison of the operations time in solving the MR/MP problem with interactive front-end processing over end-to-end batch runs is given.
