Build 6.2.10
Modifications

• Resolved an issue with solving the Optimum Replacement time when a block had the lognormal distribution as its failure distribution.
• Resolved an issue with simulation when a subdiagram block was set to use an approximate failure distribution.
• Resolved an issue with displaying and updating block user defined fields in the Item Properties Table.
• Resolved an issue with pools when Initial Stock Level was set to 0 and Restock as needed (on-condition restock) was already selected.

• Resolved an issue with Failure Rate and Pdf Plots for the analytical solution when a block had a Weibull distribution with Beta < 1.
• Resolved an issue with updating fixed durations in the Item Properties Table for the corrective, preventive and inspection maintenance distributions.
• Resolved an issue with converting projects from BlockSim 1.5 when blocks had an "Added Logistic Time for Repair" > 0.
• Added the ability to send the information from a current spreadsheet to Excel.
• Updated some printer routines that were causing problems when BlockSim was trying to read printer information when starting or shutting down.

• Added the ability for current spare part pools to acquire spare parts from off-site pools.
• Added the ability to define the Failure Detect Threshold on the inspection maintenance for a block.
• Added a System Failure Event Log to the Simulation Results Explorer and updated the headings for the System Event Log.
• Resolved an intermittent issue associated with closing the application in which the files were being saved, but the user settings were not. This occasionally caused the application to hang.

• Resolved an issue associated with the analytical solution when using IBS and the "Set Block to Off" option.
• Resolved an intermittent issue associated with the default crews in simulation in which the default crews were not being assigned to blocks already associated with preventive maintenance crews or inspection crews.

• Resolved an issue associated with blocks being linked to non-existent or deleted resources.
• Resolved an intermittent issue (Indexing Error) associated with analyzing diagrams that contain many sub-diagrams.
• Updated the Item Properties Table to include Part Numbers.
• Enhanced the analysis engine.

• Added the ability to assign Part Numbers to blocks.
• Resolved an intermittent issue associated with an error message that was being displayed when the application was shut down. This does not affect the application since the error occurred after the application was shut down.
• Resolved an issue associated with a standby container block defined as a "switch," which occurred when the switch was corrected upon inspection of another group item.

• Resolved an intermittent issue associated with analyzing certain diagrams.
• Resolved the issue with the application being minimized on the Windows taskbar when it was closed.
• Resolved an issue associated with solving for the cut sets in Fault Tree Sheets.

• Updated help file to reflect new changes in BlockSim.
• Added ability to display annotations in Diagram Sheets and Fault Tree Sheets.
• Resolved the issue with trying to close the application from the Windows Taskbar when the application was minimized.
• Resolved an intermittent issue associated with crews in simulation when crews were assigned to handle a specific number of tasks.

• Updated analysis engine to handle larger and more complex systems.
• Added ability to display system pdf equations or system failure rate equations in the System Reliability Equation window.
• Added an Item Properties Table, which allows users to view and/or edit the properties of the blocks in the Diagram Sheet(s) and Fault Tree Sheet(s) within the current project, along with any defined policies, in separate worksheets.
• The initial stock level for Spare Pool Policies can now be 0.
• Resolved an issue associated with warm standby blocks in simulation when the failure and quiescent distributions were distinctively different.

• Added a Fault Tree Interface to provide integrated fault tree analysis capabilities for users with BlockSim FTI edition licenses.
• Added a Sequence Animation utility that allows you to create and view an Audio Video Interleave (*.avi) file, which animates a single iteration of the simulation for a reliability block diagram or fault tree.
• Added a Block Details Explorer utility that allows you to view the details for the blocks and resources (if any) that are represented in the current reliability block diagram or fault tree.
• Added the ability to automatically arrange the blocks in a diagram sheet, to equalize the spacing between selected blocks and/or to make selected blocks the same size.
• Added the ability to trace the path for a selected block and/or to cascade select all blocks that are connected to a selected block.
• Added the ability to view the "minimal cut sets" that have been defined in the current RBD or fault tree.

• Expanded error checking capability in the tool that converts BlockSim 1/1.5 projects to BlockSim 6.
• Resolved an intermittent issue with the simulation not being able to start when a subdiagram's last block was another subdiagram.
• Resolved the issue in the System Reliability Equation window with equations not rendering properly under some versions of Korean Windows.

• Corrected an issue with the Load Sharing Parameter Experimenter utility. The issue occurred when the IPL model was selected in this utility. The n value returned was inconsistent with the n as defined in ALTA, ReliaSoft's Accelerated Life Testing Analysis software.
• Added a font selection option in the System Reliability Equation window to resolve issues with equations not rendering properly under some foreign versions of Windows (issue discovered under some versions of Korean windows).
• Changed the date format to correspond to the windows locale settings instead of always showing the date based on the US date format.
• Resolved some issues associated with plots and large font settings in windows.
• Modified templates to auto space blocks relative to the size of the block captions. This resolves overrun issues when using large text captions on blocks inside the template.
• Modified the simulation logic rules for spare part pools and for on-condition restock. Original logic rules triggered an on-condition restock when the condition was reached. New rules triggered an on-condition restock if during a part request the stock level is below the stock condition.
• Modified validation rules for pool max capacity. Prior validation was that max capacity had to be larger than the initial capacity plus restock quantity. New validation rules require that max capacity be equal or greater than the initial restock.
• Modified simulation logic for group items receiving maintenance actions upon a group item action. Both inspections and PM for group items are now triggered upon any maintenance action (excluding inspections) on any group item.
• Updated the on-line help file.

• Increased the flexibility when reading an XML file. The Diagram and Resource IDs will now be any number between 1 and 2047.

• Resolved the issue with static values in block properties. When multiple blocks were selected, the values appeared to be the same.
• Resolved the issue with certain text in diagrams appearing to have no meaning in international versions of Windows.
• Resolved an intermittent issue with loading default settings in the diagram options window.

• Added ability to create an availability plot using the Other Plot Type functionality in the Simulation Plot Sheet.
• Added ability to specify the lower color limit for plots and FRED reports.
• Added the ability to change block colors in FRED reports and to transfer FRED report data to a BlockSim spreadsheet.
• Updated the user mathematical tolerance in the User Setup.
• Updated the mean value and failure rate in the Analytical QCP to a higher accuracy based on the mathematical tolerance that a user enters in the User Setup.

• Updated the on-line help file.
• Updated functionality for saving the project as an XML file to include saving comments associated with the blocks and/or diagrams in the project.

• Initial Release.
