Customer Product Comparisondotted rule
This Product Comparison was created for and subsequently endorsed by LG Chemicals, who evaluated Honeywell PB, Sigmafine and other products. They eventually adopted Inlibra DR in 2005 for their Daesan plant. The comparison was made with feedback from Inlibra’s Korean customers, who had switched from Sigmafine.

Item Inlibra Other Products (Sigmafine, Honeywell)
Gross Error Detection/Removal Accurate, credible, removal is automatic Insufficient detection, and removal not automatic. (S)
Customization
requirements
Requirements that arose over past 10 years are now standard features of this product. No further customization requirements are anticipated. Requirements missing from base product. Systematic customization not possible, i.e. customizations are not adopted into base product. (S,H)
Balance Type Simultaneous Mass/Volume Balance possible. Can only perform Mass or Volume balance at one time (S, H)
Min./Max.
constraint
Yes, when D/R executes, it will respect user-
defined min/max constraints on streams.
No. (S, H)
Configurable D/R
Period
Can configure different D/R periods for each
model and can change period length for anyone model and re-run.
Only one period length available (daily) (S, H)
Multiple Period
Reconciliation
One-click reconciling for multiple periods at once (e.g. multiple shifts or days) is possible. Data Import and Composition Tracking also automatically done for multiple periods. Handles all batches within the multiple periods. Difficult to do multiple periods (S, H)
Multi-User Support Uses relational db (Oracle, MS SQL). Contains drawing (model), raw data, reconciled data. Complete multiuser support through RDB. Stored in proprietary DB or realtime DB (5). Model drawing data cannot be shared (S, H).
Define per-model
User Permissions
Yes No (5, H)
Supports D/R for
Batch or Block
Operation
Yes No (5, H)
Model Connector
(integrate multiple
models)
Yes, after modeling each plant in individual models the models can be connected with Connection Objects so that Inlibra DR can perform an overall balance. No (5, H)
Connect streams in
separate parts of
model
Long, complicated streams can be visually
simplified.
Lack of Connection Objects in the DR model makes long and complicated stream lines unreadable.(5, H)
Interfaces to 3rd
party systems
Many RTDB interfaces (PI, PHD, InfoPlus.21). Many RDB interfaces (Oracie, M5 5QL Server, M5 Access) plus a general interface module. Limited RTDB Interfaces (5, H)
Limited RDB Interfaces - additional module purchases required . (5)
Composition
Tracking
integration
Yes. Tracking is performed within the DR model such that tracking integrity is maintained. No. Composition Tracking either missing or it's a separate package from vendor. (5, H)
After-service Responsible for after-service. Additional feature requests are reviewed and may be included in standard product if this improves maintainability. Impossible using local engineers. (5, H)
Convenient
Configuration
Easy configuration with Object Oriented GUI. Model configured with menu or table method (not Object Oriented GUI). Maintenance extremely difficult. (H)
DR Performance Execution of Sparse Matrix method with gross errors already removed provides excellent performance. General Matrix algorithm slows down performance. (5)
Logical Streams Yes. Streams other than the actual balance streams can be configured that contain values calculated by formulas. Such Logical Streams can specifically be used in a graphical Summary Model. Graphical Model No (5, H)
Show previous
period data from
current period
window
Yes. Within current period window one can see previous periods' data. No - only one period is shown/editable (5, H)
Trend Functionality Within Inlibra's detail dialogs, various types of data from all the periods can be trended on multi-trend graphs. Limited types of data can be trended in single trend format. (5)
Decimal values
precise enough to
balance for
accounting
Within the DR model, all balance points are reviewed to balance to the last digit of precision. No such feature - very tedious manual manipulation of DR results required to permit accounting balance. (5, H)
Automatic DR
execution
Yes,. Not only Data Reconciliation but also Data Import, Tracking and Data Storage can automatically be executed at a predefined time. No. (5, H)*
Single model representation for configuration,
query and execution
Model configuration, query, and execution are performed using the same window, providing convenience and maintenance consistency. Model configuration is performed in a different window than query and execution.(H)
Handle Balance
Points Composed of
Constant Flows
Receipt, shipment, and tank inventory are constant flows (in most companies). Balance points that only consist of constant flows are handled properly, i.e. DR execution automatically handles this and informs user. Receipt, shipment, and tank inventory are constant flows (in most companies). Balance points that only consist of constant flows aren't handled properly. User is not informed of the issues. Manual user investigation is required.
Handling of Distribution In areas requiring distribution logic, such as Utility, DR can be performed using distribution logic. Impossible to apply distribution logic. such as in Utility during DR execution. (5, H).
Formula availability Calculated tags that contain formulas can be created from within the DR program. Calculated tag creation from within the DR program is not possible. (5, H) Virtual tag creation (in RTDB) not possible from within the DR program. (H) Limited calculation functionality exists. (5)
