dynamic positioning systems
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

“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?

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
