Simio is an object oriented discrete event and agent based simulation software developed by Simio LLC. The name came from "simulation modeling framework based on intelligent objects". to hospital to analyze operations. Simio can also be used to optimize schedules using their patented Risk Based Planning and Scheduling tool. History Simio LLC was founded by Dr. C. Dennis Pegden, CEO. Pegden has over 30 years of experience in simulation and scheduling and has been widely recognized as an industry leader. He led in the development of SLAM (marketed by Pritsker and Associates) and then founded Systems Modeling Corporation, now part of Rockwell Automation. Pegden led the creation of the simulation products SIMAN® and Arena®, as well as the finite capacity scheduling product Tempo (later renamed RS Scheduler). The Simio Product Family Simulation Simio Personal Edition Simio Personal Edition is a no cost version of Simio. This version of Simio puts no limits on what you can model and is fully functional for models up to 5 models, 30 objects and 30 steps! It is perfect for you to explore and learn Simio's simulation and production scheduling capabilities. You can also use the Simio Personal Edition to open and run models that have been built by the Simio Team Edition or higher. Simio Design Edition Simio Design Edition is the standard product and processes basic features needed for simulation, acting as the modeling tool for developers and start point for Team and Enterprise Edition. Features of Design Edition includes , 1) standard and expansive online object library, 2) 3rd party add-ins, 3) logic and workflow controls, 4) user-defined data tables and 5) customizablereports and results. Simio Team Edition In addition to basic functions in Design Edition, Team Edition has more features in model and results sharing between team members within workgroup. Simio Enterprise Edition Enterprise Design extends the Team Edition capabilities into everyday supports, and is able to provide reports, figures, and tables for schedulers. Simio Academic Edition Fully functional versions of Simio are available to students and faculty. Simio educational grants make it easy to obtain, learn and teach what your students need to be successful. The resources of the Simio Academic Community support your objectives to stay ahead of the technology curve and meet the demands of next generation technology. With software, course development, texts and discussion forums, the Simio Academic Community gets you off to a fast start. Scheduling === Scheduling software aims at two major aspects of scheduling problems, 1) detailed constraints and 2) variations, within the system. In addition to deterministic model, which built according to theoretical analysis and constraints, variations are measured to create uncertainties like congestions and delays to simulate real life scenarios. Both constraints and uncertainties are considered in model building, which gives better risk measurement. Scheduling software is also integrated with Gantt Charts, which illustrates risk measures for entities. Together with Wonderware MES, Scheduling software helps making real time decisions. Portal(Cloud) Simio uses Microsoft Azure for cloud computing purpose and brings Simulation and Scheduling results to the web. Users are able to access online model and results using common web browsers, without having to install any software. Any Simulation edition is able to upload its model to cloud. Characteristic of Simio Object oriented simulation In Simio, users can build a model by connecting various objects. Objects can be customer, operator, machine, vehicle or any other what you want to use in simulation model. Basic objects are stocked in library and users immediately create objects. Or users also can build a large object and stock it or reuse it again. Since Simio applies the same design with ribbon, users can intuitively and graphically build a model. These works do not require programming language skill. Of course more complicated intelligence can be added to objects by using “process” and in this case, basic programming skills are needed. Objects in Simio have three hierarchical structures; object definition, object instance and object realization (Figure 1). Object definition is clear notification of behaviors of all instances and they share the definition. Particular behaviors of each instance are specified by object instance. Model realization is created only when an instance is realized during model execution. Objects are characterized by properties and states. Properties specify values which do not change during execution such as inter-arrival time distribution or service time. On the other hand, states specify dynamic values which can change during model running. For example, the number of work in progress products in a manufacturing plant varies by the minute and this is a state variable. 3D animation in Simio In Simio, models create automatically three-dimensional (3D) animation as well as 2D. Users easily switch the display during both building and running simulations. In addition, users can download thousands of symbols for their objects from Google 3D Warehouse, which realizes realistic simulation. Data in Simio User can use general data sources as input data for their simulation. You can import Microsoft Excel file and csv file. Simio also provides huge kinds of output as results of simulation and all data is also exported as Microsoft Excel file and csv file. Industry Airports Simio enable airports the power to utilize simulation to test ideas of improving individual systems. Airports can get a larger perception on those adjustments’ influence upon the entire organization. Single sectors of an airport use Simio to meet objectives and show their plans to ensure a fluid process. For instance, terminal sector can model accurate systems and make adjustment in 3-D environment. Based on Simio results, decision makers can choose a relatively effective plan and improve the entire system. Manufacturing A broad set of industries can obtain optimal manufacturing solutions, with Simio's assistance. These industries include "discrete part manufacturing, automotive, consumer packaged goods, and metals & plastics". In detail, Simio can help manufactures design green field production plans and improve the Six Sigma and Lean Manufacturing processes. Moreover, companies can also reduce cost with combination of facilities and obtain efficient production plan. Military Simio can provide military solutions related to their supplies transportation, as well as resource staffing. The military also take advantage of Simio to design for both resupply and operation refurbishment. Similar to manufacturing industries, the military can also utilize Simio on their process improvement. Maritime/Ports In terms of maritime, Simio’s solutions encompass harbor design, port authorities, and terminal operators. For example, port staffs can design new container terminals or harbors, and simulate the operation of these ports. Supply chain In supply chain industry, Simio is applicable to simulate vessel schedules, predict key supply chain economic risk indicators and understand the total cost of variance on the business, including "labor variance, material obsolescence, material shortages, capital shortages, and most importantly, the demand forecast variance". Healthcare The Simio solutions for healthcare industry encompass improvement of hospitals, healthcare institutions and regional healthcare systems. These improvements pursue high effectiveness of overall operation and better service level, such as reducing waiting time of patients. Mining The basic application of Simio on mining industry encompass both open pit and underground mines. Detail application includes material handling design in an open pit mine and conveyor systems for underground mines. See Also
