What is SIM?

• Stands for System Integration Management• Directed by the System Integrated Management Office (SIMO) in an organization• Focus

– Implementation/Placement of new computer systems– Upgrade of current computer systems– Replacement of current computer systems– Removal of current computer systems

• Goals– Identify, document, and manage changes to the site architecture– Plan a timely, cost-effective, and operationally focused

implementation/upgrade/change/removal of computer systems– Execute the transition from the baseline architecture to the objective architecture– Communicate results of analysis, transition status, issues, resolution plans, and

recommendations to senior management

Site Architectures

• Baseline Architecture– Depicts the computer hardware, software, and network

connections currently installed and in use in an organization

• Objective Architecture– Depicts the computer hardware, software, and network

connections at a set point of time in the future after specific computer systems have been installed, changed, or removed in an organization

System Integration Management Review (SIMR)

System Integration Management Review (SIMR)

• Conducted monthly by the integration contractor and overseen by the SIMO

• Attended by upper management, project action officers, users, operators, maintainers, and developers

• Presents information on status of system integration plans for operations over the next 1, 2, and 5 years

IMPACT

A new highly flexible technology, hosted on all commercial middleware, for improving at runtime, the capabilities and information provided by large scale distributed systems.

A new technology for scalable automated checking of conformanceof distributed object systems to constraint-based industry and DODreference architecture standards, including security standards.

NEW IDEAS

Event pattern language expressing both event causality andevent timing, for rapidly configuring event filters, aggregators and constraints.

Complex event processing based on event patterns, for enhancing the capabilities of existing distributed systems.

Java extensions to express architecture concepts with an event-based semantics.

Complex event processing and architecture conformancechecking, hosted on commercial middleware.

IMPACT• Improved mission effectiveness for UAVs

(smoother operation, improvedmaneuverability and robust to failures)

• Rapid response to mission or operationalchanges through reconfigurable softwarearchitecture for UAVs

• Increased interoperability amongheterogeneous components

• Reduced development costs due to reuse ofgeneric control algorithms and integrationpatterns

NEW IDEAS• Intelligent control methods for mode switching

and fault tolerance in UAVs• Interchangeable control modules that allow for

changing the mission and modes quickly• Open, distributed, plug-and-play software

architecture for interoperability amongheterogeneous components
