Dynamic Positioning Systems

• Dynamic Positioning (DP) systems were born in
  1960s as a result of the increasing demands of
  the rapidly expanding oil and gas offshore
  exploration industry
• Definition Dynamic Positioning is a system which
  automatically controls a vessel to maintain her
  position and heading exclusively by means of
  active thrust
• Presently, there are over 1000 DP-capable vessels
  where most of them are dedicated to the
  exploration or exploitation of oil and gas
  reserves

Architecture Research Problem
Chemtech Architect Creating UML Models
NFR Teams on several sites Use existing modeling
tools for quantitative analysis DSM,
Performance, Dependability, Architecture
Alternatives Evaluations.
Issues with Existing Approach -Dynamic
Positioning Project Architect is a scarce
expensive resource -NFR Teams require
architecture information to model NFR
requirements -How to maintain common architecture
view across sites as architecture evolves?

Suggested Architecture Research Solution Approach
How to provide seamless global architecture view
across multiple sites to enable seamless
collaboration without excessive overhead on the
architecture research teams?
Chemtech Architect Analyze Visualize by
Creating Annotated UML Models using Open-Source
tool
NFR Teams on several sites Understand Annotate
UML Models Convert UML Model Annotation into
existing modeling Tool
NFR Teams on several sites Integrate existing
tools with Open-Source UML Tool to enable
seamless integration of UML models with
quantitative assessment tools

Quantitative Architecture Analysis Models (Drexel)

• Analytical Decision Models
• Design Structure Matrix (DSM)
• Augmented Constrain Network (ACN)
• Architecture Analysis Enabled
• Modularity Analysis can the parts be
  independently substituted with better versions
  without influencing the rest of the system?
• Net Option Valuation
• Independence Level Assessment
• Stability Analysis How likely the architecture
  is going to change? Which part is most vulnerable
  and unstable?
• Change Impact Analysis Given an envisioned
  change, which and how many parts of the system
  will be affected?
• Task Parallelism Analysis How to assign task to
  minimize communication between remote teams and
  maximize task parallelism?
• Automatic Model Transformation
• From UML Component Diagram to ACN/DSM
• From UML Class Diagram to ACN/DSM
