| | *  *  *  *  | | | --- | --- | | Markov Module | | | Markov Analysis Software Markov analysis is a powerful modelling and analysis technique with strong applications in time-based reliability and availability analysis. The reliability behavior of a system is represented using a state-transition diagram, which consists of a set of discrete states that the system can be in, and defines the speed at which transitions between those states take place. Markov models consist of comprehensive representations of possible chains of events, i.e. transitions within systems which, in the case of reliability and availability analysis, correspond to sequences of failures and repair.  The Markov model is analysed in order to determine such measures as the probability of being in a given state at a given point in time, the amount of time a system is expected to spend in a given state, as well as the expected number of transitions between states: for instance representing the number of failures and repairs.  Markov models provide great flexibility in modelling the timing of events. They can be applied when simple parametric time-based models, such as exponential or Weibull time-to-failure models, are not sufficient to describe the dynamic aspects of a system's reliability or availability behavior; as may be the case for systems incorporating standby redundancy.

| | *  *  *  *  | | | --- | --- | | ToolKit MainTain Module | | | Maintainability Software The Maintainability software module of ITEM ToolKit provides an integrated environment for predicting the expected number of hours that a system, or a device, will be inoperative, or "down", while it undergoes maintenance, based upon the tasks needed to repair the system.  **Conforms To Rigorous Standards** A comprehensive design tool for calculating MTTR, MainTain conforms to maintenance standards established in MIL-HDBK-472, Procedure V, Method A.  **Built-in Maintenance Planning** MainTain provides built-in elemental maintenance action, maintenance philosophy and fault isolation parameter groups to provide a foundation for the analysis. You can also save common maintenance tasks to a library for repetitive use. The following results are calculated for a component or group of components:   * Mean Time To Repair (MTTR) * Mean Man Hours (MMH) * Mean Man Hours per Repair (MMHR)  Use the Maintainability Software early and often to:  * Identify areas with potential maintainability problems * Make repair, replace and design decisions * Perform early assessment of downtime and personnel requirements * Plan for necessary tools and test equipment * Easily identify Replaceable Items (RIs) * Save and link essential data for use in other ToolKit modules Features  * Powerful and user friendly maintainability software * Conforms to MIL-HDBK-472, Procedure V, Method A * Mean Time to Repair (MTTR) * Mean Man Hours (MMH) * Mean Man Hours per Repair (MMHR) * Built-in maintenance planning * Identifies Replaceable Items (RIs) | |  |  | | --- | --- | |  |  |     **> Maintainability Software Tool**  **> MIL-HDBK-472, Procedure V, Method A**  **> Calculates Mean Time To Repair (MTTR)**  **> One of Thirteen ITEM ToolKit Modules**  **> Extensive Reporting and Charting Facilities** | | Contact us now for a price list, free trial or quote: sales@itemsoft.com | US: +1 (714) 408 7788 | UK: +44 (0) 2392 16 0707 | | |
|  ›  › **SpareCost** |
| | *  *  *  *  | | | --- | --- | | ITEM SpaceCost Module | | | Spares Scaling & Ranging  The Spares Scaling and Ranging (SpareCost) module of ITEM ToolKit calculates spares required for equipment supported at sites and bases; enabling you to optimize the scale of spares at sites for minimum cost. It works to algorithms derived for the Ministry of Defence: Optcost and Repstock.  **Sites** The SpareCost module generates spares holdings required at sites (first and second line repair by replacement), against a stock-out risk at the site. This scale of spares is optimized against cost of the spares held.  **Base** Base spares are required to meet replenishment demands from sites and to replace returned spares which are beyond economic repair. SpareCost calculates the most cost effective base spares holding.  **Reports**The Spares Scaling module has an extensive reports facility that includes full information of spares holding by replacement item at both site and base, as well as the expected number of failures for each component over a defined period. Features  * Powerful and user friendly spares scaling and ranging software * Uses Optcost and Repstock for spares scaling * Tree control for structured project breakdown * Identifies and calculates your stock out risk * Analyses at site and base (depot) level * Powerful charting and reporting facilities | |  |  | | --- | --- | |  |  |     **> Spares Scaling & Ranging Software**  **> Uses Optcost and Repstock**  **> One of thirteen ITEM ToolKit Modules**  **> Extensive Reporting and Charting Facilities** | | Contact us now for a price list, free trial or quote: sales@itemsoft.com | US: +1 (714) 408 7788 | UK: +44 (0) 2392 16 0707 | | |
