JMVA Introduction
JMVA An analytical evaluation tool of queuing network models using
Mean value Analysis (MVA) algorithm. User Interaction — Wizard interface
INPUT• Workload intensities• Stations • Service demands • (What-if Analysis)• (Comments)
OUTPUTTextual• Throughput• Customers numbers• Residence time …Graphical• Performance Index
Approaches
Going Through Background Comprehending concepts of JMT and JMVA
Reading Tests Written by Author Understanding major procedure of solving
Analyzing with Stan4J Forming general overview of application
Searching & Tracing in Eclipse Finding out sequences of calling methods
Testing Units Dealing with details of codebase
Architecture of Application I
Overview of the architecture: Package View
Architecture of Application II
Deeper discovery of the architecture: MVC model
Three Main Features in JMVA
What-if SolutionOffers same what-if analysis functionalities of JSIMengineExecute faster on models of small number of workload classes
XML Usage
Automated algorithm chosen
Works as an intermediate vector for passing messages among methods
Decide which algorithm to be applied by the system automatically
Main Features — Diagram
Design and Code Evaluation
User InteractionHeuristic Evaluation :
Component DependencyStan4J: Cycles occur between several packages. Too large classes with unrelated methods in it.
Complexity & Repetition Eclipse Metric: Nested Block Depth,McCabe Cycloramic
Complexity, Number of Parameters CPD From PMD: Found a 525 line (3213 tokens) duplication
Programming StyleCheckstyle : Some variables should have been set to be private, Some method should have been set to be abstract or final Puzzling and repeating method naming
Conclusion
We have gained a lot from it — interesting points
