2. Product Definition

2.1 Model Overview

The All Viewpoint (AV-1) Overview and Summary Information provides unclassified, executive-level summary information in a consistent form that allows for quick reference and comparison between architectural descriptions.

2.2 Model Purpose and Intended Use

Department of Defense Architectural Framework (DoDAF) is the basis for the capture of the Missile Defense Integration and Operations Center (MDIOC) as a system. A tailored approach is taken to select the specific DoDAF viewpoints that best represent the system being described while limiting the number of artifacts to manage. This tailoring permits efficient management and updates to a limited set of viewpoints while still capturing relevant and useful information.

DoDAF offers a common framework to represent architecture artifacts/diagrams. Additionally, DoDAF provides flexibility to represent diagrams in various formats including System Modeling Language (SysML), which is the standard used across this architecture. Establishing artifacts using SysML works towards the purpose of increasing the use and adoption of processes and products consistent with Model-Based Systems Engineering (MBSE) principles. This emphasis on MBSE is in support of and contributes to Department of Defense (DoD) and MDA digital engineering initiatives, which seek to increase transparency, traceability, and accessibility of system artifacts and perspectives.

The MDIOC Operational Viewpoint-1 (OV-1) High-Level Operational Concept Graphic (Figure 1) describes the MDIOC as a provider of enabling capabilities, services, and activities to consumers from across the DoD, including Combatant Commands (CCMDs). The MDIOC provides support across a broad spectrum of the MDA mission space, to include support for Research, Development, Test, and Evaluation (RDT&E) and Missile Defense System (MDS) operations. The MDIOC’s core capabilities include both infrastructure and information technology (IT) enterprise services.

The MDIOC Facility AV-1 Overview and Summary Information is a core artifact in the MDIOC Technical Baseline (TB). As such, it is intended to describe how the MDIOC operational architecture relates to the MDIOC system architecture. The MDIOC systems and subsystems that support the mission(s) described within the OV-1 are shown in the Systems Viewpoint-1 (SV-1) in Figure 2.

This AV-1 provides an overarching view of the MDIOC mission, but primarily discusses the physical architecture of the actual elements, which are the systems and subsystems of the

Missile Defense Integration and Operations Center (MDIOC) All Viewpoint-1 (AV-1) Overview and Summary Information

MDIOC facility. There is an important distinction between information architecture used in Systems Engineering (SE), which the SV-1 supports, and physical or engineering architecture, which is conventionally understood as description of the physical layouts (e.g., halls, walls, structural support, etc.) used by facility and infrastructure teams. Therefore, in the context of this document, the use of “architectures” refers to system-level architectures used by the SE discipline, rather than physical architecture (e.g., blueprints, floor plans, etc.). As a discipline, SE is concerned with the relationship of information and data, and the supporting physical platforms. Each system described in the SV-1 will have its own set of artifacts that further decompose the MDIOC as a system into additional subsystems and components.

3. Detailed Description The MDA uses the capabilities of the MDIOC to support operations activities, as well as Research, Development, Test & Evaluation (RDT&E) tests and events. The MDIOC can be described from both an operational context (i.e., the missions and consumers it supports) and as a facility (i.e., physical and IT infrastructure). The MDIOC, in an operational context, describes how it supports and interacts with key internal and external nodes of the MDA mission. As a facility, it hosts multiple organizations that provide the MDA and the greater DoD with enterprise-level technical integration and system-level operational services and products.

The MDIOC as a system describes the breakdown in components and services that exist to ensure the building is capable of executing the mission.

MDA operations for missile defense capabilities have been executed at the MDIOC since 1988, providing around-the-clock operational system/service support for missile defense analysis, system engineering and integration, test and evaluation support, and maintenance of systems for the reliability, availability, and sustainment of the MDA missions. The OV-1 (Figure 1) provides the array of organizations/consumers aligned to the capabilities, services, and activities they receive from the MDIOC. A significant portion of the MDIOC is used as operations centers, support centers, laboratories, testbeds, and event control centers. It is treated the same as a National Range, similar to Vandenberg Space Force Base (VSFB) and Reagan Test Site (RTS), for scheduling and range documentation purposes. Additionally, the MDIOC provides its core tools of communications and network capabilities, computing capabilities, engineering services, event services, business operations, and facility and security services.

The MDIOC facility provides services to tenant organizations and assures availability of those services under the direction of the MDIOC Director (MDA/SS). The MDIOC facility infrastructure was specifically designed to provide an unbiased, level playing field environment for conducting joint and combined interoperability missions.

The MDIOC facility is comprised of two primary buildings; Building 720 Research Building (RB), which provides the Operations and Research, Development, Test & Evaluation (RDT&E) functions, and Building 730 Consolidated Support Facility (CSF), which provides offices for support staff, a cafeteria, coffee shop, and additional conference rooms.

Table 3 provides the current list of the consumers/organizations and missions that the MDIOC supports.

3.1 MDIOC Facility System-of-Systems

The MDIOC system-of-systems is a collection of all the systems and subsystems that comprise the MDIOC facility. This system-of-systems provides the necessary services to the MDA and other DoD entities located within the facility.

The MDIOC facility systems depend significantly on the Schriever Space Force Base (SSFB) Central Utility Plant (CUP) for its external utility services, as shown here:

SSFB Central Utility Plant (SSFB CUP) External to the MDIOC facility, the SSFB CUP provides the essential electrical and mechanical services to the MDIOC. Although essential to the MDIOC facility systems, the MDIOC FOM team is not responsible for the systems within the SSFB CUP.

SSFB CUP Electrical Utility Services The SSFB CUP provides the MDIOC Electrical System with electrical power. The SSFB CUP systems transform the incoming 115kV utility power, provided by Mountain View Electric Association (MVEA), to the necessary distribution voltage of 12,470 VAC, where power is received by the MDIOC Electrical System.

The SSFB CUP includes a backup power system consisting of seven diesel engine generators that provide power to MDIOC in the event of an MVEA outage. This backup system is designed to engage automatically upon detection of a power disruption.

SSFB CUP Mechanical Utility Services The SSFB CUP provides the MDIOC Mechanical System with chilled water, conditioned (soft) water, and steam.

These services are then circulated throughout the MDIOC using mechanical distribution systems that provides the air pressurization, heating and cooling mechanisms for both the Heating, Ventilation and Air Conditioning (HVAC) and Plumbing subsystems.

The following sections describe the MDIOC systems and subsystems, as represented in the MDIOC Facility SV-1 (Figure 2).
