What’s New

Network Availability Prediction 3.0.0

The new features in Network Availability Prediction 3.0.0 are:

Network Availability Prediction

  • The report database is now based on the SQL Server LocalDB database engine instead of SQL Server Compact. This technology provides the following benefits: 1) an increase in the maximum database size from 4 GB to 10 GB, 2) Complex queries are processed much faster (orders of magnitude in some cases), and 3) full SQL Server Transact-SQL syntax is supported.
  • The mouse wheel may now be used to vertically shift and scale network diagrams.
  • When browsing for bitmap files, the open file dialog now allows users to choose files of type Bitmap,JPEG,GIF,TIFF and PNG.
  • The parent block is now always selected when paging up from another block. Previously, this only happened if the parent block was in the selection history.
  • Import from SQL server databases now caters for fields containing spaces.
  • Users may now optionally remove phonetics when importing from an Excel spreadsheet. The appropriate option needs to be set in the Application Options dialog, Import tab.
  • The last grid layout displayed is now remembered between program sessions.
  • New methods have been added to the dll allowing users to obtain the table name and row index of the currently selected object (for plugin apps).
  • The drawing of large diagram reports has been significantly speeded-up.
  • Vote and quantity numbers have now been activated for CCFs.
  • Switching delay calculations may now be disabled when applying probabilistic cut-offs (Sets Generation tab in the Project Options dialog).
  • Excel import and export now handles multi-line text fields. Excel 2007 special identifiers _x000D_ are also removed on import.
  • Import/Export to Excel has been speeded up for very large Excel files.
  • Bitmaps may now be stored inside a project.
  • Plugins may now perform analyses so long as the appropriate module licence is available.

Report Designer

  • A feature has been added allowing reports to be displayed in full screen mode.
  • To display a report or the report designer in full screen mode select the ‘Full Screen’ toolbar button. To return to normal mode from full screen mode select the ‘Full Screen’ toolbar button again.
  • The performance of user code programmable columns has been improved.
  • The time taken to repaginate reports has been reduced by a factor of 2 to 3 in some circumstances.
  • The time taken to publish PDF and Word text column reports has been significantly reduced.
  • A feature allowing the top 1000 rows of selected tables and views to be displayed in the SQL Query Wizard has been added. This is to assist in the construction of the SQL query by helping to identify potential join columns.

Network Availability Prediction 2.0.14

The new features in Network Availability Prediction 2.0.14 are:

  • The Details dialog (accessed from the Results Summary dialog) now allows you to navigate to blocks in the diagram.
  • A ‘Copy’ button has been added to the Results Summary dialog allowing users to copy results to the clipboard.
  • New legacy import options have been added to the application settings dialog. They allow matching of new CCF model Ids and descriptions to the legacy block Ids and descriptions, the removing of detached parts and the renaming of repeat blocks on import.
  • Switching delay calculations are now taken into account when applying an unavailability cut-off.
  • Database ‘integer’ import fields may now be matched to ‘double’ application fields.
  • Tool tips have been added to list controls in the Grid Layouts dialog (General tab) to identifier the field ID.
  • Users may now specify a ‘hop count’ to limit the length of paths generated during the analysis process.

Network Availability Prediction 2.0

The new features in Network Availability Prediction 2.0 are:

64-bit Application

Network Availability Prediction 2.0 runs as a 64-bit application allowing much larger models to be analyzed than in previous 32-bit versions. The efficient analysis of large networks requires significant amounts of memory for the computation of paths through the network and the determination of the minimal cut sets required for availability prediction.

Please note that Network Availability Prediction 2.0 requires a 64-bit operating system.

Improved Analysis Performance

Average computing times for analyzing large networks have been substantially reduced through the development of more efficient path generation algorithms.

Alternative Combinatorial Analysis methods

Network Availability Prediction 2.0 provides an alternative combinatorial cut set evaluation method to analyze large networks where availability is dominated by lower order combinations of network element failures.

Enterprise Version

The Isograph Enterprise System provides the framework for controlling multi-user project and library access through a central database system. Access rights to projects, libraries and administrative functions are controlled through user permissions. This allows an organization to:

  • Assign administrators to organize access rights to groups of users
  • Build a centralized hierarchy to organize projects and libraries
  • Restrict access to projects and libraries where necessary
  • Control the check-in and check-out of projects for modification
  • Track the current projects that are checked-out to users
  • Provide version control of projects and libraries

Enhanced Library Facilities

Users may now attach multiple libraries when editing the current Network Availability Prediction project. Network elements, parts and CCF models may be easily transferred to the current project tree or diagram using drag and drop facilities.

Enhanced Grid View

The new grid view allows access to data tables making up a Network Availability Prediction project. Users may now construct their own custom grid layouts using filter and sort facilities and take advantage of the extensive Find and Replace functionality.

Report Designer

The Report Designer has been enhanced and extended to provide export and publishing facilities in Word and PDF format. Wizards are provided for report creation

Import/Export

Import and export facilities have been improved to include the latest versions of Excel and Access. SQL Server import and export is now possible.

Diagram Notes and Hyperlinks

Notes and hyperlinks may now be added directly to the network diagram. Note text and hyperlinks may be displayed by hovering the mouse cursor over the appropriate symbol in the diagram.

Spelling Checker

The new spelling checker allows users to check selected tables or the entire project for spelling errors.

Plugins

If you are licensed to use the new Plugins facility you will be able to create programmable plugins that read, analyze and modify data from the current Network Availability Prediction project. Plugins may be used to create specialized reports, perform specialized operations or conversions, modify project data and call external libraries or processes. A plugin may be exported for use by other users.

Application Programming Interface (API)

A new and rich API (Application Programming Interface) has been added allowing .Net programmers to quickly build interfaces to other applications. All the standard project tables may now be accessed through the Dynamic Link Library (DLL) facility. The Network Availability Prediction DLL enables users to seamlessly link their databases or external applications to Network Availability Prediction projects. For example, the DLL may be used to create a custom link from a database for importing parts data into a Network Availability Prediction project.
