The Unit Spares Analysis Methodology (UNISAM) computer software package was developed to provide an automated means to determine optimum component sparing levels for electric power generating units. It provides users with the means to quickly and accurately determine which spares and the number of each that should be placed in inventory to support a given level of unit production. With UNISAM, cost savings are maximized for any selected level of total spares investment. This manual is a guide to installing and using the UNISAM software package. It contains the information and procedures required to perform component sparing level analyses. The core of the UNISAM process is multiple executions of the UNIRAM calculational software operating upon UNIRAM data input files that are automatically updated under the control of the UNISAM software. UNISAM does not require the UNIRAM software package. Because UNISAM does, however, require the use of a UNIRAM data input file for operating, it is recommended that users of UNISAM obtain The User's Guide for the UNIRAM Availability Assessment Methodology: Version 3.0, (the UNIRAM User's Guide) to assist in the development of UNIRAM models for use with the UNISAM software. The UNISAM software is modularized, providing a user-friendly interface and menu structure, for development and modification of data files interactively or in a batch mode and for selection of execution options for performance of sparing level analyses under both full and partial demand operating conditions. UNISAM will perform analyses with UNIRAM input files that are compatible with all versions of PC UNIRAM through Version 3.0. 28 figs., 3 tabs.
