History

The Simulation Interoperability Standards Organization (SISO) originated with a small conference held April 26 and 27, 1989, called, "Interactive Networked Simulation for Training". The original conference attracted approximately 60 people. The group was concerned that there was activity occurring in networked simulation, but that it was occurring in isolation. The group believed that if there were a means to exchange information between companies and groups that the technology would advance more rapidly.

The group also believed that once the technology begins to stabilize then there would also be a need for standardization. The technology and the consensus of the community would be captured in the standards as networking or simulation technology matured. [2] The pre-history of SISO starts with SIMNET, a DARPA program from 1983 through 1991 that demonstrated the feasibility of networking substantial numbers of (relatively) low-cost simulators on a "virtual battlefield."

Based on the success of this program, the US Army initiated a large-scale program called Combined Arms Tactical Training. In order to ensure that multiple teams of contractors would be able to bid on various components of this program, the Army Program Manager for Training Devices (PM TRADE), soon to be renamed as the Army Simulation Training and Instrumentation Command (STRICOM - now PEO STRI), in conjunction with DARPA and the newly established Defense Modeling and Simulation Office (DMSO now Modeling and Simulation Coordination Office (MSCO)), initiated a series of workshops at which user agencies and interested contractors could work together to develop standards based on the SIMNET protocols.

The "First Conference on Standards for the Interoperability of Defense Simulations" was held on 22–23 August 1989 in Orlando, Florida. DIS Workshops were held semi-annually from 1989 through 1996. The first Simulation Interoperability Workshop (SIW) held under the SISO banner was the 1997 Spring SIW in Orlando. SIWs have continued semi-annually since 1997. In 2001, SISO also began holding annual Euro-SIWs at various locations in Europe. In 2003, the IEEE Computer Society Standards Activities Board (SAB) granted the SISO Standards Activities Committee (SAC) status as a recognized IEEE Sponsor Committee. SISO is also recognized as a Standards Development Organization (SDO) by NATO. In addition, SISO is a Category C Liaison Organization with ISO/IEC JTC 1 for the development of standards for the representation and interchange of data regarding Synthetic Environment Data Representation and Interchange Specification (SEDRIS).

SISO was an original sponsor of SimSummit. [4]

The VHSIC Hardware Description Language (VHDL) is a hardware description language (HDL) that can model the behavior and structure of digital systems at multiple levels of abstraction, ranging from the system level down to that of logic gates, for design entry, documentation, and verification purposes. Since 1987, VHDL has been standardized by the Institute of Electrical and Electronics Engineers (IEEE) as IEEE Std 1076; the latest version of which is IEEE Std 1076-2019. To model analog and mixed-signal systems, an IEEE-standardized HDL based on VHDL called VHDL-AMS has been developed.

Message-oriented middleware (MOM) is software or hardware infrastructure supporting sending and receiving messages between distributed systems. MOM allows application modules to be distributed over heterogeneous platforms and reduces the complexity of developing applications that span multiple operating systems and network protocols. The middleware creates a distributed communications layer that insulates the application developer from the details of the various operating systems and network interfaces. APIs that extend across diverse platforms and networks are typically provided by MOM.

ISO/IEC/IEEE 12207Systems and software engineering – Software life cycle processes is an international standard for software lifecycle processes. First introduced in 1995, it aims to be a primary standard that defines all the processes required for developing and maintaining software systems, including the outcomes and/or activities of each process.

The High Level Architecture (HLA) is a standard for distributed simulation, used when building a simulation for a larger purpose by combining (federating) several simulations. The standard was developed in the 1990s under the leadership of the US Department of Defense and was later transitioned to become an open international IEEE standard. It is a recommended standard within NATO through STANAG 4603. Today the HLA is used in a number of domains including defense and security and civilian applications.

Distributed Interactive Simulation (DIS) is an IEEE standard for conducting real-time platform-level wargaming across multiple host computers and is used worldwide, especially by military organizations but also by other agencies such as those involved in space exploration and medicine.

SEDRIS is an international data coding standard infrastructure technology created to represent environmental data in virtual environments. Environmental data represented by SEDRIS may be concrete, such as trees and mountains, or abstract, such as the behavior of light. The infrastructure frees users to place their focus on application development and also facilitates the exchange of data for reuse and wider scrutiny. Research into shared ways to represent environmental data was begun in the 1980s in order to permit distributed simulations to work together. SEDRIS was launched in 1994 by program managers of the United States Army's Simulation Training and Instrumentation Command and the US Department of Defense's Defense Advanced Research Projects Agency.

ISO/IEC 10967, Language independent arithmetic (LIA), is a series of standards on computer arithmetic. It is compatible with ISO/IEC/IEEE 60559:2011, more known as IEEE 754-2008, and much of the specifications are for IEEE 754 special values (though such values are not required by LIA itself, unless the parameter iec559 is true). It was developed by the working group ISO/IEC JTC1/SC22/WG11, which was disbanded in 2011.

Live, Virtual, & Constructive (LVC) Simulation is a broadly used taxonomy for classifying Modeling and Simulation (M&S). However, categorizing a simulation as a live, virtual, or constructive environment is problematic since there is no clear division among these categories. The degree of human participation in a simulation is infinitely variable, as is the degree of equipment realism. The categorization of simulations also lacks a category for simulated people working real equipment.

The Open Smart Grid Protocol (OSGP) is a family of specifications published by the European Telecommunications Standards Institute (ETSI) used in conjunction with the ISO/IEC 14908 control networking standard for smart grid applications. OSGP is optimized to provide reliable and efficient delivery of command and control information for smart meters, direct load control modules, solar panels, gateways, and other smart grid devices. With over 5 million OSGP based smart meters and devices deployed worldwide it is one of the most widely used smart meter and smart grid device networking standards.
