How do I use the different libraries in Simio?
In the standard Simio installation, the Standard Library, the Flow Library, and the Extras Libary are attached by default and the Project Library is an integral part of the project. The Standard, Flow, and Extras libraries can be opened by clicking on their respective names at the bottom of the libraries window (only one can be open at a time).
What is a process in Simio?
In Simio a process is defined as a flowchart using stepsthat are executed by tokens and may change the state of one or more elements. Referring again to Figure 5.6, you’ll note an object (Parent Object) that contains a process consisting of three steps.
How do I implement ABC in Simio?
In some simulation products, ABC must be implemented by adding logic and data items to track each cost as it is being incurred. More comprehensive simulation products have built-in ABC. Simio is in the latter category. Most objects in the Simio Standard Library have a Financials category.
What can you do with Simio?
Before we finish our model, we’ll explore one more aspect of tables. It’s very common to have data in a table where each row corresponds to an entity type, as we have in our model. It’s also common to have the entity type be selected randomly. Simio allows you to do both within the same construct.
What are the 3 modeling paradigms in Simio?
The intelligent objects are built by modelers and then may be reused in multiple modeling projects. Although the Simio framework is focused on object-based modeling, it also supports a seamless use of multiple modeling paradigms including event, process, object, and agent-based modeling.
What is time starved Simio?
The resource enters the Processing (busy) state when 1 or more units become busy. It leaves that state and enters the Starved (Idle) state when all units become idle. The average time in spent in that (1 or more units) busy state was 55.5133 minutes per transition.
What are objects Simio?
A Simio object is defined by creating a set of graphical process flows that describe the object's behavior. A process is a flowchart that describes a sequence of activities and decisions that are made by the object. A process may span time and may be constrained by limited resources.
What is buffer logic in Simio?
Buffer Logic – Balking Options A new Balking Options page in the Simio help provides examples for the different property options. Simio also includes statistics on the total number of balked entities for a buffer in the automatically reported results.

What does random triangular mean in simio?
In Simio you specify a random sample from a triangular distribution as Random. Triangular(minimum, mode, maximum), where mode is the most likely value. For example Random. Triangular(6,9,12) will generate random samples with a minimum value of 6, most likely value of 9, and maximum value of 12.
What is an entity in Simio?
Entity is an object definition and is a base object, i.e. one of the fundamental building blocks that other objects are built with. Its properties and states are defined as part of the Simio engine and are not under user control. Costs and Priority are examples of states that are defined on Entity.
How do you add a warm up period in Simio?
You can create a mock warm-up period by using an OnRunInitialized Process. An OnRunInitialized Process is executed when the model is first initialized.
How do you zoom in on Simio?
Press the right mouse button and move left and right to rotate the view, or up and down to zoom in and out. You can also zoom using the mouse wheel.
What is Simio Standard Object Library?

Use this library to quickly model a wide range of systems. This library is briefly summarized in the following table. Name. Description.
What is Simio used for?
Simio can be used to model a wide range of systems including manufacturing, healthcare, supply chain, transportation, defense, and mining. Although these systems are all unique in their own respect, from a modeling point of view they are very similar.
What is Simio in computer science?
Simio is a tool for building and executing dynamic models of systems so that you can see how they perform . Simio “acts out” and displays a 3D animation of the behavior of your system over time. Simio lets you see your proposed systems in operation before you build them or change them.
What are the benefits of simulation?
Benefits of simulation. Simulation lets you see the impact of change. You can quickly make changes to your model to test out your ideas without disrupting your real system . With simulation you make your mistakes in the model, and not in your business. Changes may not always produce the desired or expected results.
9.1 Model 9-1: ED Model Revisited
In Section 8.2.7 we added hospital staff to our Emergency Department (ED) model and incorporated entity transportation and animation (Model 8-3). However, we didn’t account for the actual patient treatment and we didn’t perform any experimentation with the model at that time.
9.2 Model 9-2: Pizza Take-out Model
In Model 9-2 we will also consider a related resource allocation problem. The environment that we are modeling here is a take-out pizza restaurant that takes phone-in orders and makes the pizzas for pickup by the customer.
9.3 Model 9-3: Fixed-Capacity Buffers
The final model for this chapter involves modeling an assembly line with fixed-capacity buffers between the stations. In an assembly line, items move sequentially from station to station starting at station 1 and ending at station n n, where n n is the length of the line.
9.4 Summary
In this chapter we’ve looked at Simio models of three systems — each involving one or more advanced simulation concepts. In addition to the modeling aspects, we also focused on the experimentation with each of these models and introduced the OptQuest simulation-based optimization add-in.
9.5 Problems
Modify Model 9-1 so that it includes the patient physical movement and Nurse/Aide escort functionality from Model 8-3. Compare the resource requirements with those of Model 9-1. Does including this level of detail “improve” the validity of the results? If so, why? If not, why not?
How often should I update Simio?
We encourage you to update your systems to every major release (typically twice per year). Because Simio follows an agile development process, you do not have to wait for the next major release - new features and patches are available as frequently as monthly.
What is the purpose of Simio?
The process orientation of Simio makes it easy to teach foundational principles of simulation, while the use of the Standard Library of objects makes it easy to teach the benefits of simulation to students less interested in the technology than its effective use.

What is OptQuest Simio?
OptQuest is offered for Simio as an optional add-on to the standard Simio products. OptQuest enhances the analysis capabilities of Simio by searching for optimal solutions to your models. OptQuest helps remove some of the complexity by automatically searching for the optimal solution for you. You describe your simulation problem and it searches for input controls to maximize or minimize your objective (i.e. maximizing profit or minimizing cost).
What is an API in Simio?
An application programming interface (API) is an interface implemented by a software program to enable interaction with other software. Though Simio has had a small but growing API for quite a while, significant work was done since Version 2 to enhance the offering including the introduction of a new method on the IModel interface called BulkUpdate, which can be used to greatly improve performance when adding a large number of objects to a model.
What is document report in Simio?
This generates an html report containing a summary of all objects and the non-default data and properties in your model. This is useful for capturing a snapshot of your model for examination or storage outside of Simio.
What is the Simio time?
In Simio, events are characterized by an execution time (the simulation time when the event occurs), a reference to a procedure call (to be executed when the event occurs), and a reference to an Object (which provides additional data to the procedure, when necessary).
What is Simio language?
Simio is an object-oriented language in which all model constructs are Simio Objects derived from the same base object. Most Simio users will primarily use objects from the Simio Standard Library for constructing models. Entities, Resources, Servers, Workstations, Sources, Sinks, Nodes, and Connectors are commonly used Objects from the Standard Library. Underneath, Simio is based on Processes that are comprised of individual Process Steps executed by Tokens. Standard Library objects’ behaviors are implemented (by the object designer) using processes. While most models will be built using these highlevel Objects, users (and developers) have complete access to Simio processes and can develop complete models as well as reusable Objects using Simio processes. In addition, users can augment the behavior of existing Objects using Add-on Processes and/or by Subclassing existing Objects. Simio models themselves are actually Objects that can be embedded in other models. The object structure of Simio facilitates the development of custom Object libraries that can simplify the modeling process in different application domains.
What is simulation project?
A simulation project entails running experiments. Experiments are differentiated by the use of alternatives in a model’s logic and/or input data. For example, alternative part-sequencing rules and/or varying the numbers of various types of machines (resources) might be tried in the model of a production system. Similarly, the number of loading and unloading berths in a harbor might be varied to assess the impact on system performance. Each experiment consists of one or more replications (trials). A replication is a simulation that uses the experiment’s model logic and data but its own unique set of random numbers, and so produces unique statistical results that can be analyzed as part of a set of such replications (all of which are independent). A replication consists of initializing the model, running it until a run-ending condition is met, and reporting results. This "running it" phase is called a run.
How does simulation software work?
We now comment briefly on why a detailed understanding of "how simulation software works" supports interactive probing of simulation-model behavior. In general, simulation models can be run interactively or in batch mode. Interactive runs are of use when checking out (verifying) model logic during model building and when troubleshooting a model if execution errors occur. Batch mode is then used to make production runs.
What is a black box approach to simulation?
A "black box" approach is often taken in teaching discrete-event simulation software. The external characteristics of the software are studied, but the foundation on which the software is based is touched on only briefly or totally ignored (for lack of time). Choices made in implementing the foundation and the impact of these choices on step-by-step model execution might not be studied at all. The modeler might then not be able to think things through when faced with developing good approaches for modeling complex situations, using interactive tools to come to an understanding of error conditions arising during model development, and using interactive tools to verify that complex system logic has been modeled correctly. The objective here, then, is to describe the logical underpinnings of discrete-event simulation and illustrate this material in terms of various implementations of discrete-event simulation software.

The Crucial Role of Randomness
- One of the often overlooked aspects in the analysis of a systems performance is the role that randomness plays in determining the behavior of the system. By randomness we mean the idea that things occur within our system with variation from one to the next. Classical examples of randomness include the time between arrival of customers, the time between failures of equipm…
A Simple Simio Model
- Let's examine a Simio model of a very simple system in which entities arrive, are processed by a server, and then depart the system. This could represent work pieces being processed on a machine, or passengers checking in at a kiosk in an airport. Although Simio provides a framework for building custom objects, it includes a Standard Object Library that lets you immediately start …
Interpreting Results
- Now that we have built our simple model, we would like to use it to gain understanding and insight into the system. We do this by setting up a set of experiments that define specific changes that we would like to evaluate, and then running those experiments to see the impact of the changes that we make on the system performance. The following table is a summary of experiments perf…
