What is Simio

Simio is a 3D simulation modeling tool that combines the rapid modeling of objects with the power of processes. Patented architecture Modern yet established product 5 years, version 6

Rapid growth Accelerated use within and across companies. > 800 universities, multiple textbooks and

languages.


Rapid Modeling in Action


Simio in Action

Build a quick model. Embellish the animation. Examine the results.


What makes Simio different?

Simio Architecture Experimentation featuresDevelopment processMixed discrete/flow systemsRPS support


Simio Architecture True Object-Oriented Framework Models built from objects. Simio provides Standard, Flow, Extended

Flow, Crane, Transportation Libraries; users can create new objects /custom libraries.

Objects are built from processes (patented) and require no programming.

Object instances can be customized with add-on processes (patented).

User benefit: rapid and flexible modeling


Experimentation Features

Create and execute scenarios with controls, responses, and constraints.

Distribute replications across multiple cores / computers for fast execution.

Use and develop third party add-ins (e.g. OptQuest, KN).

Drill into your results using the Pivot Grid. Assess error and risk using SMORE plots.Distribute the results on Dashboards *


Development Process

Agile development process based on 3-week scrum cycle.

Fully automated and 100% unit testing. .NET Framework Simio Insiders

Result: fast and responsive development

Simio Flow ConceptSimio offers a uniquely powerful approach for modeling systems involving continuous fluid or mass flow.

Entity

Regulator

Flow Transfer Flow Transfer

AAn entity in Simio has a physical volume and weight density, and thus may be used torepresent not only a discrete item but alternatively a quantity of fluid or other mass.

A Regulator element is provided by the Simio engine. This element is the core mechanism for controlling volume or weight-based flow transfers of entities between locations.

A Container element is provided by the Simio engine. This element may be used to define a volume or weight capacity constrained location for holding entities that are representing material flow.

Entities can flow into and fill the cross sectional area of links being used to model piping or mass flow conveyor networks.

Entity


Modeling Fluid or Mass FlowNotable advantages to the flow modeling framework in Simio:• Assigning and tracking the attributes of entities representing material flow segments is

readily supported (e.g., product type, routing destination, composition data).

• Potential dual representation of an entity as either a discrete item (e.g., a barrel or a pile) or as a quantity of fluid or other mass (100 liters of oil or 100 tons of coal).

• Model behavior is both accurate and run performance efficient.

Flow Segment

Flow Library Object OverviewFlowSource – used to represent an infinite source of flow of fluid or other massof a specified entity type.

FlowSink – used to destroy flow that has finished processing in the model.

Tank – used to model a volume or weight capacity constrained location for holding flow.

ContainerEntity - used to model a vessel for carrying flow.

Filler – used to fill a ContainerEntity.

Emptier – used to empty a ContainerEntity.

FlowNode – A node specifically designed to regulate flow. Can model an‘Input’ or ‘Output’ node for controlling flow into or out of another object (such as the Tank object). Also may be used to model a flow control point in a network of links.

FlowConnector – May be used to model a direct, zero travel distance connectionfrom one flow node location to another.

An Transportation and Extended Flow Library is also available that contains several other flow related objects. (e.g., Tanker, Hopper Car, Stockpile, Solidifier, Liquefier). These libraries are not currently part of the standard Simio installation but may be easily downloaded for free. To download, go to the Support tab in the Simio software and click on the Shared Items button.


Transportation Library

The Transportation Library is used to model trucks, ships, trains, robots, and pipes. The library works with both discrete and flow entities.


Crane Library

The Crane Library is a collection of objects that are specifically designed to work together in order to model oneor more cranes operating simultaneously in a bay.


Strategic Direction: RPS

Simulation models are typically used to enhance the design of a system: Facility layout. Material handling. Supply Chain.

Risk-based Planning and Scheduling extends the use of models to improve daily operations.


Why Traditional APS Falls Short

Based on deterministic times and no unplanned events - leads to optimistic plans/schedules that cannot be achieved in practice – goes from feasible to infeasible over time

Decision makers have no basis for judging the risk associated with a plan/schedule.

Accurately predicting delivery dates with a high level of confidence is difficult if not unattainable

Simio RPS (Patent Pending)

RPS is the dual use of a simulation model to generate both a realistic and detailed plan and an assessment of the risk associated with that plan.

Simio adds variation to processing times and incorporates unplanned events and automatically replicates the model (across processors) to generate risk measures. Probability of meeting target. Expected completion time.

Key Advantages

Risk analysis to assess the quality of the deterministic schedule.

Flexible modeling environment to accurately capture the facility constraints.

Single model for design and operation. 3D animation of schedule generation.


Simio Editions Express Edition Fully functional 3D modeling system < $5K

Design Edition Create custom objects.

Team Edition Freely share models Execute models across a network

Simio Portal (Coming Soon) Execute Simio simulation models and

share the results across the enterprise Simio Enterprise/Team Edition users can

upload Models/Dashboards to the PortalModels can then be simultaneously

accessed and run using a web clientModel results can be viewed in custom-

designed Dashboards on a desktop web clients or mobile devices.

Summary

Simio combines the rapid modeling of objects with the power of processes.

Simio RPS extends the benefits of simulation into the daily operations of a system.

Simio Portal Edition will enable deployment across the enterprise.
