# Easy to Build Flowchart Models

## Flexible Array of Building Blocks

The software provides an extensive and flexible selection of building blocks to serve different functions within the flowchart model. Some of the most commonly used modeling features include the ability to:

• Use variables to store numerical values. This might be an input value that you wish to vary during the simulation, or an output value that you wish to capture.
• Build simple or complex equations for a wide variety of purposes. The equation in a RENO function takes inputs generated during simulation, while the equation in a static function is evaluated without any input supplied.
• Check incoming values against one or more conditions in order to trigger various responses. This includes "if statements" with true/false outcomes for single or multiple inputs (conditional blocks and logic gates), as well as "switch statements" with multiple possible outcomes (branch gates).
• Use tables to store an array of values in rows and columns, allowing you to read from or write to each cell during simulation.
• Use summing gates to perform mathematical operations on multiple incoming values to determine a single output value. For example, you might use a summing gate to add the values of several blocks, or to divide the value from one block by the value from another block.
• Control the flowchart path, including loops and other complex configurations, using flag markers and go-to-flag blocks, stop flags, counter blocks and reset blocks.
• Use result storage blocks to compute averages, sums, arrays, minimums/maximums and more.

In the Synthesis version, we've added the ability to:

• Use binary nodes to determine outcome probabilities, which makes decision/event trees quick and easy.
• Use Synthesis models to describe any probability that can be constant or described by a statistical distribution.
• Use a simulation definition to trigger simulation of a BlockSim diagram from within a RENO flowchart, so that you can use one or more results from the simulation in the flowchart.

## Use BlockSim Results Within RENO Flowcharts

Now RENO flowcharts and BlockSim diagrams are directly integrated into the same software interface so you can work with both types of analyses together, and share many of the same resources.

Even better, you now have the option to use outputs from BlockSim RBDs or fault trees as inputs in your RENO flowcharts. For example, if you have an analytical diagram in BlockSim that describes the reliability of a system, you can publish a model that will provide the system reliability when it's needed in any RENO flowchart. Likewise, if you have a BlockSim simulation diagram that estimates a system's operating cost, uptime, availability and other factors of interest, you can use the new simulation definition resource to draw any of these results into a RENO flowchart.

In addition, you can now use dynamic models for specific inputs in your BlockSim diagrams and then use RENO flowcharts to set the values for any given simulation. For example, instead of defining a fixed cost for a repair crew or spare part in a system RBD, you now have the option to obtain the cost from a RENO flowchart, if desired.

## Simulation Worksheets

The new Simulation Worksheets feature allows you to vary values that are used in simulating a BlockSim RBD or RENO flowchart. This enables you to investigate the effect of one or more settings on the simulation results. Two of the most useful applications are the ability to:

• Design an experiment in DOE++ —> simulate the experiment in BlockSim or RENO —> then return to DOE++ and analyze the simulated "response" data.
• Perform batch simulation of an RBD, using different input values for each simulation. For example, this tool makes it easy to run a set of simulations that compare a variety of possible scenarios by altering specific inputs (e.g., cost, reliability, etc.) for each simulation.
Enhanced in Version 10!

## Customize the Look of Flowcharts with Skins

Diagram Skins allow you to maximize the visual impact and appeal of your flowcharts by applying a set of preferences for the colors, lines, text and images used. Choose from a variety of skins included with the software or create your own! Now in Version 10, diagram skins are now universal across all Synthesis applications. This means that a single skin can contain the appearance settings for all types of diagrams in BlockSim/RENO, Weibull++/ALTA and Xfmea/RCM++/RBI.
