Why a New Language?

Industry Development and
Endurance Timelines
• Industry has embraced the benefits
of global technology.
• Development time has decreased.
• Perishability/obsolescence
increasing
4
Current Environment
Adversary Development and
Counter-Measure Timelines
• Adversaries are also leveraging
COTS technology.
• Emerging threats demand we
enhance the speed in which we
deliver new capabilities.
SOURCE: Systems 2020 Study Final Report, Booz Allen Hamilton, August 2010

DoD Development and Endurance
Timelines
• Long development times
• Good for fixed threats.
• However, against asymmetric
threats perishability/obsolescence
increasing.
5
Current Environment
U.S. is Faced with Highly
Unpredictable, but Surmountable
Threats
• Acquisition methods designed for
warfare during the Cold War are
ill-suited for the dynamic nature of
threats today.
SOURCE: Systems 2020 Study Final Report, Booz Allen Hamilton, August 2010

Complex Systems Implications for
Systems Engineering
• Larger, more complex systems development
implies:
– A need for larger, distributed teams
– A need for a clear concise way to express the system
design (clear, logically consistent semantics)
– New tools to enable collaboration across the entire
lifecycle
6
Complexity has been identified by many as a
critical problem facing system engineers

Complexity
• With the growth of the
Internet and daily
changes in IT, systems
have become more
complex and change
more rapid than ever
before
• Systems engineering
methods have not kept
up with these changes
• SE has been relegated
to the beginning of the
lifecycle
7
From a presentation by Dr. Michael Ryschkewitsch,
NASA Chief Engineer, at CSER Conference 15 April 2011

How Does SE Typically Respond to
Complexity?
• Focus on upper-left hand side of the “Vee”
• Systems Architecture and Requirements
Development
– More complex MBSE languages
– More complex processes and governance
• More layers of abstraction
– “Systems of Systems”
– “Family of Systems”
– “Portfolio Management”
• Need more time and money!
8

More Money Is a Problem
• Calls for doing more
with less continue
• Need for lower labor
and tool costs
essential for
acceptance of SE
across the lifecycle
9
How can we simplify things enable “quicker/
cheaper”? Let’s start with the language we use

Overlap Among MBSE Techniques
10
SOURCE: Grady. J.O. (2009). Universal Architecture Description
Framework, INCOSE.

State of Current “Languages”
• In the past decade, the Unified Modeling
Language (UML) and the Systems Modeling
Language (SysML) have dominated the
discussion
• Why?
– Perception that software is “the problem”
– Hence need for an “object” approach
• SysML was designed to relate systems thinking
to software development, thus improving
communication between systems engineers
(SE) and software developers
11

Why Objects Are Not the Answer
• Although SysML may improve the communication
of design between SEs and the software
developers it does not communicate well to
anyone else
– No other discipline in the lifecycle uses object
oriented design and analysis extensively
– Users in particular have little interest/acceptance of
this technique
– Software developers who have adopted Agile
programming techniques want functional
requirements (and resent SEs trying to write software)
– Many software languages are hybrid object and
functional
12

So What Do We Do?
• Recognize that our
primary job as SEs is
to communicate
between all
stakeholders in the
lifecycle
• Be prepared to
translate between all
the disciplines
• Reduce complexity in
our language to
facilitate
communication
13

Lifecycle Modeling
Language (LML) Overview
14

Lifecycle Modeling Language
(LML)
• LML combines the logical constructs with an
ontology to capture information
– SysML – mainly constructs – limited ontology
– DoDAF Metamodel 2.0 (DM2) ontology only
• LML simplifies both the “constructs” and
“ontology” to make them more complete, yet
easier to use
15
Goal: A language that works across the full
lifecycle

LML Models
Primary Entities
• Asset/Resource
• Connection
Primary Entities
• Action
• Input/Output

LML Ontology* Overview
• Taxonomy**:
– 12 primary entity classes
– Many types of each entity class
• Action (types = Function, Activity, Task, etc.)
• Relationships: almost all classes related to each
other and themselves with consistent words
– Asset performs Action/Action performed by Asset
– Hierarchies: decomposed by/decomposes
– Peer-to-Peer: related to/relates
17
*Ontology = Taxonomy + relationships among terms and concepts
** Taxonomy = Collection of standardized, defined terms or concepts

LML Schema Elements
• Action

LML Translation
• Two types of mapping for tailoring:
– Map names of classes to enable other “schema”
models to be used
– Map symbols used (e.g., change from LML Logic to
Electrical Engineering symbols)
– Enable diagram translations (e.g, Action Diagram to
IDEF 0)

LML Summary
• LML provides the fundamental foundation for a
tool to support SE in the cloud
• LML contains the basic technical and
programmatic classes needed for the lifecycle
• LML defines the Action Diagram to enable better
definition of logic as functional requirements
• LML uses Physical Diagram to provide for
abstraction, instances, and clones, thus simplifying
physical models
• LML provides the “80% solution”
– It can be extended to meet specific needs (e.g.
adding Question and Answer classes for a survey tool
that feeds information into the modeling)
39

LML Tool Needs
41
Scalability and collaboration across
the lifecycle are essential

LML Tool Needs
• At a high level, we know that any tool must
scale to accommodate a very large data set
– We are trying to capture information about the
systems of systems being developed, their
interactions, decisions, risks, cost, and many
other parameters throughout the lifecycle
• Also, collaboration is critical as a large data
set means many, many people involved, who
use different terminology and perhaps even
different languages – worldwide
42
Fortunately we have a new environment
for our LML tools – Cloud Computing

NASA “Requirements”
43

44
Tool for Vision for MBSE
• Tool must be designed as
a MBSE tool using
Lifecycle Modeling
Language (LML)
– All artifacts must be
produced from the tool
using standard reports
• Tool must enable both
seamless data flow and
distributive, collaborative
teams working on the
same model
• Implies need for ability to
scale “infinitely” on
demand

45
Tool for Complexity
• Tool must be designed for
use throughout the lifecycle,
thus enabling end-to-end
systems engineering
– Legacy systems are a key
part of any modeling
environment – LML has
specific information classes
for capturing designs at
different times in one
knowledgebase
• Tool must embed
simulation, which enables
real time simulations as well
as the ability to scale
“infinitely” to hundreds of
server instances
• Tool must also reduce
complexity by use of special
input screens, which enhance
configuration management as
well

46
Tool for Multi-Decadal/Generation
• Tool must enable tracking of
performance over time as
Characteristics of the
Assets
• Environments and
conditions can also be
captured as evolved over
time and location (including
orbital locations)
• Tool must evolve of the
lifecycle of systems, but the
data must be captured and
reused throughout the
lifecycle

47
Tool for Uses and Challenges
• Tool needs to create a
CONOPS report based on
scenario modeling
• Capture Issues and
Decisions, as well as Cost
for cost, schedule and
performance tradeoffs
• TRL levels must be easily
captured in the tool
• Software as a service
provides inexpensive tool,
while scalability enables
fidelity level required; LML
method enables rapid SE
design and analysis
• Tool should automate what can
be automated to reduce
“wetware” requirements and
enhance teaming

48
Tool for Uses and Challenges
(continued)
• Tool should enable design down to
detailed level (if desired), as well as
V&V support
• Manufacturing enhanced by linking
design to CAD/CAM systems (export
design information as required)
• Use of XML files to import/export
data from other design tools
• Design rationale, assumption and
other programmatic information
captured as part of Issues, Risk and
other program-related elements of
LML
• Standards should be captured and
developed using the tool;
enforcement by tailoring “personal
trainer” version
• Operations data and obsolescence part
of LML elements (Assets, Characteristics
and Time)
• Use of a scenario-based approach
enables better information capture from
operators

49
Tool for Managing Complexity
• Tool in conjunction with a
process should capture a
reasonable number of
scenarios for modeling and
simulation, using a test
matrix approach (move
away from “peeling the
onion”)
• Use “test matrix” approach
to provide breadth of
problem space, including
failure modes, to capture
the full functionality required
• Test must become even
more dependent on
simulation

50
Tool for Managing Complexity
• Tool should enable
sharing of models, thus
creating a “library” of
component models
• Contributions should be
made from academia
(tool should be free
access to academia) to
this library
• Government sponsored
research can also be
made available to the
NASA family via website

IMPLEMENTATION OF LML
Innoslate® is the first tool to implement LML completely
56

Implementation of LML
• Prior to development of LML, a schema was
developed called KBAD and implemented in
Vitech’s CORE tool
• We used this for a number of years to get
many of the rough edges out of the schema
• As such, LML’s ontology can easily be
implemented in a number of tools
• The diagrams, particularly the Action
Diagram, must be implemented by tool
vendors
• Innoslate® is the first of these LML tools
57

What is Innoslate?
• A tool to capture requirements, design, operations,
and support information using systems
engineering principles
• Enables requirements analysis and management
with direct linkages to design models
• Applies cloud computing technology to model-
based systems engineering techniques and
discrete event simulation
• Available on the public cloud, private clouds, and
client-server platforms
• Implements the lifecycle modeling language (LML)
and enables translation to UML, SysML, DoDAF
(DM2), and other languages
58
Innoslate® provides software as a service (SaaS)

What are the system
requirements?
• Operating system
– Any (Windows XP/7, MAC OS X, Linux)
• Devices
– Any (PC, Mac, iPad, Android Tablet)
• Software
– Any modern web browser (Google Chrome,
Firefox 5+, Safari, limited support for IE 9+ or
IE 7+ with Google Chrome Frames)
• No downloads required
59

What Can Innoslate® Produce?
• Tool Capabilities
– Early Simulation/Design Validation
– End-to-End Design Management and Collaboration
– Repository of Analyses from Any Tool

Sample Problem
Let’s look at an example of using
Innoslate® through the lifecycle
76

To Further Our Understanding
• We will use a sample problem called FireSAT
– “FireSAT is arguably the most famous space mission
that never flew. The idea for this fictitious mission was
first developed in Space Mission Analysis and Design
(SMAD) [Larson and Wertz, 1999].”
– See ASSE Section 1.6 and Chapter 9 for more details
• Task for the ASSE book: “Develop the mission
concept for an on-orbit fire detection system.”
• As we go through the lifecycle, we will capture
data entities using this problem
• As we may not have the subject matter experts on
this, it will identify a real-world occurrence – we
might have to build a team to perform this analysis

Test Verification Matrix (TVM)
Test Case
Verification Requirement
Number and Name Description Criteria
VT.1 FireSAT Developmental Test SRD.3.2.2 Spectral Resolution
The space vehicle shall detect wildfire emissions
in the wavelength range of 4.2 plus or minus 0.2
micrometers. Rationale: This requirement comes
from the FireSAT wildfire definition trade study
and corresponds to a wildfire temperature of
690K. Optimum wavelength for a fire at 1000K
would be 2.9 micrometers; however, there is no
atmospheric window at that wavelength so 4.2
micrometers represents a good compromise.
Meets detection temperatures
below threshold values.

Innoslate® Support for Project
Management
• Process Modeling (Action Diagram)
• Tracking (Action, Cost, and Decision
classes; simulation)
• Risk Analysis (Risk class and diagram)
• Timeline chart
96

Creating Reports
97

Reports in Innoslate®
• Reports for every class
• General reports
– Comments, Entity Table, etc.
• Complex reports with wizards
– CONOPS, Requirements Document
• Specialty reports
– JCIDS, DoDAF, MODAF
98

LML Bottom-Line
• LML provide a simplified ontology that
should meet the needs of most projects
with little or no extensions
• The cloud provides a new capability to
deal with complex problems
• Innoslate® was designed to implement
LML and is not expected to be the only
tool that does so
