ExtendSim 8 ExtendSim 8 -- released July 12, 2010

ExtendSim 8

Scenario Manager

One of the more notable features added to ExtendSim 8 was the Scenario Manager. It gives the MOST COMPLETE understanding of how a model reacts to different factors. Explore projected outcomes as the Scenario Manager varies model inputs. Results change as the input changes; thus, run multiple experiments with the same model.

Essentially, the ExtendSim Scenario Manager keeps track of multiple what-if models, all based on the same model. It does this by assigning a named scenario to each combination of variables you choose to examine. For example, create best-, worst-, and typical-case assumptions for input values. Then recall each of these scenarios to see how the model behaves under different conditions. For comparative analysis, recall scenarios in combination, such as best-case sales and worst-case costs.

Suite AT

Advanced Resource Management

Advanced Resource ManagementThe addition of Advanced Resource Management (ARM) in ExtendSim provided an integrated system for organizing resources, distinguishing between them, and allocating them throughout a model. ARM provides a convenient and straightforward way to define complex resource requirements for items and a flexible set of rules for how resources get allocated to them. Plus, it provides automated methods for quickly changing resource information and generating statistical reports.

The ExtendSim ARM system's organization and allocation architecture is fueled by an ExtendSim database that represents, manages, and tracks the states and properties of resources, pools, groups, and allocation and release rules. Six blocks on the ExtendSim roster form the ExtendSim Advanced Resource Management team. At the heart of the ARM is the Resource Manager providing a convenient dialog-based interface.

SuiteAT

Equation capabilities were enhanced in ExtendSim 8

The Equation Editor was added to most equation-based blocks as a separate, scrollable window to view, enter, and edit equations.

Equation-based blocks got their own debugging tools so you could now set breakpoints and conditions for equations, step through lines of code, and examine values of variables.

When a set of commands (definitions, assignments, or functions) have multiple uses, the added ability for equation-based block to call include files simplified model maintenance. These include files allow functions and message handlers to be overwritten and compilation to be conditional.

SuiteATORCP

Sophisticated tools to search database tables for the best record appeared in ExtendSim 8 with the introduction of the Query Equation and Query Equation(I) blocks. These blocks have proven to be indispensable when a database holds information that is required for making decisions in a model.

SuiteAT

Other new blocks introduced in ExtendSim 8

Block Info
Reports information about the block connected to its input connector.

DBStatistics
Calculates a set of basic statistics for all of the records in a database field.

Event Monitor
Displays the event calendar in discrete event models, revealing the event times for all event posting blocks.

Link Alert
Registers a section of a database so that the block receives a message when data in the linked database changes.

Model Interface
Creates an interface for controlling a model.

Memory Usage
Calculates the amount of memory required for each block, global array, or database table in the model. It is helpful in locating where memory is being used in large models.

MYOB DB Dialogs
Shows how to develop ExtendSim database popup menus.

Slider
Provides a flexible slider for models. It can be cloned to the worksheet or Notebook, be linked to a database, and more.

Time-saving Shift-Click was added in 8 to open a dialog in which you may choose which block or feature should get a given variable. Shift-Click an appropriate dialog item to add variables to the Find, Optimizer, Scenario Manager, and Statistics blocks as well as for Sensitivity Analysis and in custom block development.

SuiteATORCP

Plus many user-requested functions, system variables, and message handlers.

ExtendSim 9.0ExtendSim 9.0 -- released July 17, 2013

New Statistics (DB) Report SuiteATORCP
Statistics (DB) ReportStatistics (DB) report contains final values for output parameters. Statistical data from each simulation run is stored in an ExtendSim database, organized by block type so that there is one table per type of block. Blocks included in the report can be all blocks in the model or a user-defined subset of the blocks. Report tables can be exported to external databases or Excel when the simulation is complete.

Of course, ExtendSim’s existing text-based reports have been maintained, but the new Statistics (DB) report provides better organization, presentation, and accessibility of model results.

This sample report shows resource usage in a healthcare model.
 
ADO Database Support (Windows only) SuiteATORCP
Data Import/Export for ADO DatabaseCommunicate with the most commonly used external databases. ActiveX Data Objects (ADO) provides built-in import and export support for Microsoft Access, SQL Server, and MySQL. ADO sends an entire table of information at one time, providing high-speed data interchange.

ADO is faster and easier to use than ODBC and it does not require defining a data source name (DSN) before accessing data. It automatically configures the ExtendSim database when importing and the external database when exporting. Plus mirrors fields and records between the source and its destination.

For example, here is the dialog of the Data Import/Export block configured for ADO Import from a SQLServer database into an ExtendSim database. The ADO interface is designed so that the modeler can access an ADO database by adding a Data Import/Export block to the model and selecting the internal and external data sources.
Flow Attributes SuiteAT
Flow AttributesEnhancing ExtendSim’s unique discrete-rate technology, flow attributes track the properties of the type of product that is modeled as a continuous "flow" in a discrete event environment. Examples of flow include bulk material such as grain or ore, liquids and gases, and product in a high-speed production line. A flow attribute is a quality or characteristic of flow that stays with it as it moves through the model, such as type, product, color, and so forth. Flow attributes provide information about the flow and allow you to organize quantities or volumes of flow into layers. The entire set of attribute values assigned to a particular layer is what distinguishes it from other layers. In other words, all the units of flow in a layer possess the same set of flow attribute values.

Flow attribute usage includes:
The flow held in a Tank can be organized into individual, distinct layers. This allows you to control where incoming flow is deposited and which type of outgoing flow next exits.
Flow can be routed through the Merge and Diverge blocks based on flow attribute values.
Attributes are assigned to the flow by the model builder. They become linked to sections of flow that pass through the blocks, according to settings in the blocks’ dialogs.
The flow held in a Tank can be organized into individual, distinct layers. This allows you to control where incoming flow is deposited and which type of outgoing flow next exits.
Excel Add-In SuiteAT
Excel Add-InThe ExtendSim DB Add-In for Excel works with database text files to transfer data between an ExtendSim database and Microsoft Excel. Excel has become the ubiquitous repository for simulation data and is often used for ad-hoc analysis. However, because of performance and scalability issues, Excel is a less-than-ideal database. To bridge the gap between Excel as a data repository and the ExtendSim database, we created an Excel Add-In that allowed exported ExtendSim database text files to be imported into Excel for editing, then exported back to ExtendSim.

ExtendSim 9 contains an entirely new version of the Add-In that supports most of the construction and editing features available in ExtendSim. This means that you can completely specify a new ExtendSim database in Excel, including parent/child relationships, cell randomization, named distributions, and more. Afterwards, export the database for use in ExtendSim models. In addition, the new Add-In leverages the latest Excel features such as ribbon interface, XML-based file format, and 1 million rows/16,000 columns. Plus, database consistency checking is now faster and has expanded capabilities.
Item Logging SuiteATOR
Track items and their states as they move through a simulation. In addition to the existing ExtendSim trace features, the Item Log Manager (ILM) block supports customized data collection and report configuration from within ExtendSim by doing two things:

During the simulation run, the ILM block directs other blocks in the model to collect data on items as they pass through. These “remote” data collecting blocks include History, Activity, Queue, Queue Equation, and Resource Item. Each of these blocks can be remotely instructed to collect specific item property information for the ILM through its “Data Collection” tab.
Once the remote blocks have collected the data, the ILM packages it into a report. You can control which types of data are included in the report and the order in which the data appears. This is done on the ILM block's “Configure Log” tab.

Item LoggingOnce the run is complete, any number of reports can be generated from the data that has been collected in the remote blocks. These reports can be generated after each run either automatically or manually. Item loggingAny number of ILM blocks can be used in any one model with each ILM block responsible for generating its own report. The ILM also supports generating reports across multiple runs.

This screenshot is an example log of aircraft operations, showing the individual plane ID’s and their corresponding entry and exit times through various points in the model.
Templates Library SuiteATOR
Templates LibrarySpeed up model building by using pre-built templates for common modeling situations. These templates are actually submodels within hierarchical blocks - constructs created in ExtendSim by combining just a few blocks together.

ExtendSim’s Templates library blocks are similar to standard blocks in that they contain an icon, help, blocks, and animation that can be used directly by the modeler. However, they contain the combined functionality of many blocks. As with any ExtendSim block, simply drag a block from the Templates library into the model and change the parameters to reflect a specific modeling situation.

Template library blocks include:

. Activity (cycle-based shutdown)
. Activity (load / unload)
. Create (arrivals vary by time)
. Queue (batch all items)
. Queue (dump contents)
. Queue (hold until quantity reached)
. Queue (random renege)
Smart Connections SuiteATOR
Intelligent connection line control better automates the modeling process when moving blocks around. Imagine That has developed a series of features collectively called “smart connections” that allow the modeler to quickly and easily modify models by moving blocks into strategic positions.

Bump to Connect
  When a block from the Item or Rate library is placed in the model and its input connector is placed on an output connector of the same type, ExtendSim will automatically connect the blocks, spaces them evenly, and aligns the connectors.
Auto Insert
  Drop a block onto an existing connection line so either the block's input or the output connector is on that connection line. Smart connections will increase the spacing between the existing blocks and insert the new block inline between two existing blocks.
Connection Routing
  If a block is moved, ExtendSim will reroute the connection lines so they will not cross over the icon of the block.
Other New Blocks
Get(R) and Set(R) SuiteAT
Both the Get(R) and Set(R) blocks support the Rate library's new flow attributes feature.
Set(R)
The Set(R) block is for setting value or string flow attributes.

Get(R)The Get(R) block displays either multiple flow attributes from one location or one flow attribute from multiple locations.
Meter SuiteATORCP
MeterProvides more flexibility and features than the Meter control (Model>Controls>Meter). For example, the color and pattern of the indicator change when the current value has reached specified high and low values. Use the Meter block as a progress bar or to animate a hierarchical block.
Other New Features Added in ExtendSim 9
Equation-based blocks SuiteATORCP
. New input and output variables in equation-based blocks.
. Options added in equation-based blocks that provide more control as to when the equation executes.
Data import SuiteATORCP
New options for importing a named range of data from Excel.
Interval statistics SuiteATORCP
Record the mean, variance, confidence interval, and standard deviation at specific intervals during the simulation using interval statistics.
Quantile statistics SuiteATORCP
Can now be calculated within ExtendSim.
Multi-component failure modeling SuiteATOR
New options are available for multi-component failure modeling.
Functions & message handlers SuiteATORCP
There are a number of new functions and message handlers.

UI and Block Enhancements

String Attributes

-If a change is made to the value of a string attribute, all the blocks that were referencing the old attribute value will now reference the new value.

-If the index for the value of a string attribute changes (the order of the values for the string attribute change), all the blocks that were referencing that value will be alerted to the change in location.

-Changes to string attribute values defined in the database are now error checked at the beginning of the run. This provides more freedom to manipulate databases without having to worry about losing critical pieces of information.

-A new string attribute interface in the Executive block allows modelers to make global changes to string values that are referenced in other blocks in the model.

Advanced Resource Management (ARM) Enhancements

-Non-Preserved Batching

Advanced resources attached to items entering a batching block (Batch and Queue Matching) are now transferred to the batched item. Note: This only applies to non-preserved batching.

-Non-Preserved Unbatching

Advanced resources attached to an item entering the Unbatch or Query Equation(I) block are now shared equally across all of the unbatched or “spawned” items. These shared resources have a “shared count”. As the cloned items holding shared resources go through release blocks, the resources’ shared counts are decremented.

-Non-Redundant Resource Allocation

If ARM resources are already attached to an item as it enters an ARM queue in the Queue and Queue Equation blocks, those attached resources are now used to help satisfy the new allocation requirement wherever possible.

-Exclude Resource Release Options

The Resource Release block now has the option to exclude certain resources from release based on that resources’ ability to satisfy one or more specified requirements. This is a way to retain resources on an item that will be used to satisfy some future downstream allocation requirement.

In addition to adding new features in the 9.2 release, we improved its quality and stability. Just a few of the fixes include:

-Calling RunSimulation on a model while it is already running no longer reports an error.

-In the BlockMove message handler, changing selected blocks could ocassionally cause the rest of the moved blocks to not receive the message. This has been corrected in 9.2.

-OLEGetNames and OLDGetDispatchNames no longer crash if one of the names is longer than 31 characters.

-Extend Block Profile file is created in Documents directory, not Application directory, for permissions issues.

-The BLOCKUNDELETE message is now sent after all undeleting has been completed, rather than being sent to each block as the undeleting process proceeds.

-When manually changing a random cell, the random seed will now correctly take on the new value.

-When using more than one connection message type simultaneously (CONNECTORTOOLTIP CONNECTIONMAKE, CONNECTIONBREAK, and CONNECTIONCLICK), the resulting values of ConnectorToolTipWhich() are now correct.
