Robert Neumann, P&G Manufactring GmbH:"nach anfänglicher Skepsis bin ich sehr überzeugt von den Möglichkeiten der Software. Meine Erfahrung mit Simulations -Software im Speziellen ist dabei zwar recht beschränkt, jedoch bin ich der Meinung, dass extendsim zahllose Möglichkeiten
bietet und ich für unsere Zwecke (Simulation von Packing-Linien) mir nichts vorstellen kann, dass nicht möglich wäre. Vor allem das User Manual und die vielen Beispiele sind dabei sehr hilfreich!"

Neue Eigenschaften in Version 9

ES9 bullet New Statistics (DB) Report

dbreportStatistics (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.

ES9 bullet ADO Database Support (Windows only)

Communicate with the most commonly used external databases. ActiveX Data Objects (ADO) providesadoreport 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.

ES9 bullet Flow Attributes

Enhancing ExtendSim's unique discrete-rate technology, flow attributes track the properties of the flowattributestype 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:

v bullet 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.
v bullet Flow rates through the Valve block can be calculated based on flow attribute values.
v bulletFlow can be routed through the Merge and Diverge blocks based on flow attribute values.

v bullet 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.

ES9 bullet Excel Add-In

The 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.excel add in

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.

ES9 bullet Item Logging

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:

v bullet 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.item login

v bullet 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.

Once 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. Any 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.

ES9 bullet Templates Library

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:

v bullet Activity (cycle-based shutdown)
v bullet Activity (load / unload)
v bullet Create (arrivals vary by time)

v bullet Queue (batch all items)
v bullet Queue (dump contents)
v bullet Queue (hold until quantity reached)
v bullet Queue (random renege)

ES9 bullet Smart Connections

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.
v bullet Bump 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.

v bullet Insert Over Connection

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.

v bullet Connection Routing

If a block is moved, ExtendSim will reroute the connection lines so they will not cross over the icon of the block.

suite LogoAT LogoOR Logo


ES9 bullet New Menu Commands

v bullet Read/Write Index Checking (Database menu)

Gives an error message when a model tries to read or write data using a non-existent or incorrect database address or index. Useful for debugging block code that interfaces with the database.

v bullet Smart Connections (Edit menu>Options>Model tab)

If unchecked, turns off the intelligent connection line control discussed in Smart Connections.

v bullet Statistics (DB) Report (Run menu>Report Type>Statistics DB)
Automatically stores and organizes statistical data from each simulation run in an ExtendSim database as discussed in Statistics (DB) Report.

ES9 bullet Other New Blocks

Get(R) and Set(R)
Both the Get(R) and Set(R) blocks support the Rate library's new flow attributes feature.

set rThe Set(R) block is for setting value or string flow attributes.

The Get(R) block displays either multiple flow attributes from one location or one flow attribute from multiple locations.

UI and Block Enhancements


ES9 bullet String Attributes

v bullet 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.

v bullet 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.
v bullet 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.
