Aspen Petroleum Supply Chain V7.2 Release Notes 7

New Features

This section describes the new features in the Aspen Petroleum Supply Chainfamily of products.

Note : The V7.2 release of PSC products is primarily a defect fix release.Resolution of many of these defects added new functionality. New features

associated with these changes are highlighted here as well as in the SoftwareFixes chapter.

Aspen PIMSThe new features and enhancements listed below apply to Aspen PIMS.

New Matrix GeneratorThe New Matrix Generator released in V7.1 was made more robust and is now

capable of running more types of models.ABML CARB correlations have been expanded and enhanced for working withthe new XLP matrix generator.

Multi-StartThis feature has been enhanced and now allows selection of starting points.In addition, improvements have been made to work more effectively for moretypes of models.

Adapter InterfacesWorked was performed to improve interfaces for blend events andSupplyItems.

XNLP SolverEnhancements were made to reduce execution time and to increase thelikelihood of finding global optimum.


8/26


Extended TagsConverting to and working with extended tags has been made easier byallowing users the option to run existing short tag model in extended tagmode without changing the tag internally using the Preserve Original Tagsoption.

Matrix ComparisonMatrix Comparison reports can now be viewed directly from within PIMS.

Penalty StructuresPenalty structures for specifications that span plants and periods have beenimplemented.

New CorrelationsAmended CARB3 correlations have been implemented in Advanced Optimization (AO).

Warning MessagesThe following Warning Message has been added to the system:

Global BLNSPEC Entry at XXX and YYY Ignored due to the local settingSMALL

Row XXX in Table ROWS has Non-Empty Entries in Conflicting Columns Unsupported input database table XXX skipped

TABLE XXX does not exist in the model. The updates will be ignored for CASE YYY

In addition, numerous warning and error message details have been added tothe online help documentation. Refer to the warning and error messageoverview pages in the online help for specifics.

Dialog Box ModificationsThe following dialog boxes have been changed:

General Model Settings Miscellaneous TabThe Preserve Original Tags option has been added which allows you

to retain the original tags even though you have indicated to use ExtendedTags. General Program Options Execution Tab

The New Close Model upon PIMS Exit option has been added whichallows you to close your model prior to exiting PIMS. This prevents themodel from automatically loading when you relaunch the application.

XNLP Settings Advanced Tab


9/26


The Calculate Holding Costs based on Closing Inventory optionallows you to include holding costs associated with target inventory levelsinto your calculation, thus reflecting the actual or full costs of holding theinventory. This option is only available for XLP.

Known Issues

Below are the known issues associated with Petroleum Supply Chain V7.2products.

Aspen PIMSBelow are issues specific to V7.2

PIMS AO on a 64-bit operating systemAfter installation, for PIMS AO , utilizing parallel processing, to runcorrectly under a 64-bit operating system, you will need to modify thePATH environment variable from:

:\Program Files\MPICH2\bin

to the following:

:\Program Files (x86)\MPICH2\bin

Aspen Petroleum Scheduler

Below are issues specific to V7.2 Character tags sent to unit.xls and automation functions will no longer

be padded to four (4) characters with spaces. This is in preparation forlong tag support in V7.3. The consequence is that Excel lookups using

VLOOKUP/HLOOKUP/MATCH, where strings are matched, should now betrimmed. Also please check your orinvb.dll for similar string matchingissues.

Crude run events associated with a crude unit that has parameterswill be clipped so that no two (2) events will overlap. This is necessarybecause only one set of parameters can be active at any given time. If the crude unit does not have parameters, these events will not be clipped.Set the CONFIG setting CLIP_CRUDE_RUN_EVENT to N to suppressclipping regardless of whether the unit has parameters. The default is Y.
