Computer Simulation

Computer Simulation WARSIM 2000 is simulation software, used by the armed forces. Extensive, thorough, and tiring work has been done on thgis program. It covers almost all aspects and situations required for realistic, meticulous and a complete simulation. Information Technology has lead to the advancement of the tools required to build the simulator. Information Technolgys guideleines and technolgy have reinforced this creative simulator General Description of Operational Capability.

WARSIM 2000 will increase the effectiveness of commander and battle staff training by dramatically increasing the realism and the scope of the available training environment. In conjunction with other services’ simulations, WARSIM 2000 will provide a complete operational environment with scenarios drawn from the entire operational continuum to support Army, joint and coalition force training distributed across the globe. a. The WARSIM 2000 simulation system will use a computer-based simulation and associated hardware to support the training of unit commanders and their battle staffs from battalion through theater-level as well as to support training events in educational institutions. Designed and built using modern computer technology, modern software engineering techniques, and validated algorithms and databases, it will allow units world-wide to train using their organizational equipment.

A key feature of the system will be its use of technology to minimize the total Army’s overhead associated with supporting training. The system will be designed to meet emerging Distributed Interactive Simulation (DIS) standards and protocols to facilitate linkages with DIS compliant simulators and live training events. b. The WARSIM 2000 simulation system will consist of, or use, several components: (1) Computer-based battle simulation models that portray the joint and combined environment needed to support Army training events. (2) Software modules for linking WARSIM 2000 to other simulation models to expand the training environment for joint force training exercises. (3) Databases.

(4) Computer systems to run the simulation models and support the databases. (5) Technical control systems/workstations for use by personnel in an exercise support function e.g., simulation controllers, analysts, and opposing/ surrounding forces role players. (6) Flexible and responsive terrestrial/satellite communications gateways and media for transmitting voice, data, facsimile, and video between different elements at remote locations involved in supporting a training exercise. c. WARSIM 2000 will meet the Mission Need Statement’s (MNS’s) requirement for providing a training environment that will allow unit commanders and battle staffs to focus their warfighters and systems in countering threats across the operational continuum.

WARSIM 2000 must provide an environment that presents problems to stress and stimulate commanders and their battle staff to assess the situation, determine courses of action, and plan and issue new orders in a timely manner, all while using their organizational equipment and procedures. d. Logistical support for WARSIM 2000 will be based on a government- owned contractor-supported system. The government will own necessary hardware, have all proprietary rights to the developmental hardware and software components, and full license rights to the non-developmental software components of WARSIM 2000. Contracted logistical support will provide for the maintenance of government-owned computer hardware at all times. e.

The acquisition and development strategy for WARSIM 2000 must abide by several constraints. (1) The WARSIM 2000 acquisition must build upon the successful infrastructure of current simulations so that the training community (Army and international) can train in an evolutionary progressive yet consistent manner. The Army has invested significant resources into developing its training simulation systems, linking them with other service simulations via the Aggregate Level Simulation Protocol confederation, and proliferating them throughout the Army and the international community. While these systems have shortcomings that must be fixed, they provide a training environment and representations of combat that have been accepted by the training community world-wide. The WARSIM 2000 acquisition must allow the confederation of simulations structure to evolve in a manner that allows current users (Army and international) to maintain access to the confederation without having to make a substantial near-term investment in resources. (2) Meeting the WARSIM 2000 requirements will demand significant technological innovations.

However, there are many existing and developing systems that could and should be part of the overall solution. The acquisition strategy must ensure that developers optimize the investment of each service in existing systems (instead of starting from a blank sheet of paper) and insert echnology into the training environment in a way that improves training. (3) Fielding of new capabilities, whether they be functional representations or technological enhancements, must be either practically transparent to the user or be accompanied by training so the user can understand and receive the benefit of the new capabilities. (4 The acquisition strategy must allow for regular user involvement in the development process. User evaluations and requirements must serve as a primary source for determining changes to the system.

2. Threat. Rather than counter a specific threat, WARSIM will provide a training environment capable of representing threats from across the operational continuum. 3. Shortcomings of Existing Systems. Current simulations were designed for training corps and division staffs on command and control techniques for Army operations in mid-intensity combat. Current software is bound to proprietary operating systems and hardware.

The software design, especially the underlying representation of terrain, precludes representing the detailed functionality required for resolving the high resolution interactions needed to train commanders and battle staffs at levels from battalion to operational level commanders in joint scenarios for war and operations other than war. 4. Capabilities Required. WARSIM 2000 will support commander and battle staff training from battalion up to theater level. While the major simulation models of WARSIM 2000 will run on computers housed in fixed regional facilities, transportable Simulation Support Modules (SSMs) will provide support functions under the control of a senior controller at locations near the training unit. Users of the simulation will train under the guidance of a senior trainer, usually the unit’s commander, the next higher level commander, or an instructor at institutions. WARSIM will provide users a complete training environment consisting of simulations, data, support functions and communications.

a. System Performance. The following description of requirements for the WARSIM 2000 training environment addresses in turn each of the functional components described in paragraph 1.b. (1) The Simulation. WARSIM 2000’s simulation component must have the following functional characteristics.

(a) General Attributes. (i) Size. The model must be large enough to support a multi- echelon corps or theater exercise. The model must also be able to link to other copies of itself to support larger exercises. The simulation must also be able to support multiple, concurrent, smaller training exercises, such as several battalion headquarters training independently.

(ii) Weather. The simulation must accurately portray the impact that weather elements have on operat …
