Incremental System Development

Incremental System Development

1. Modularization

   • Reduces complexity
   • Higher level of abstraction
   • Prerequisite
     • Configuration management
     • Incremental Development
       • Balanced cost
         • Cost reduction

2. Material and methods

   • QUEST
     • DES system from Denob Robotics
       • Integrated 3D Capabillities
   • GUI
     • Graphical User Interface
       • Models built
   • SCL
     • Simulation Control Language
       • Coded
         • Customized logic
   • BCL
     • Batch control language
       • Run experiments
   • CVS
     • Concurrent Versions System
       • Support configuration Management
         • Allow concurrent development
           • Binary files
             • CAD
           • Able to work in heterogeneous environment

3. Incremental Development

   • Few elements
   • Little detail
   • Holistic View
   • Not large models
   • Dividing into stages
     • Vertically
       • Remove defects
     • Horizontally
       • Defects
     • Bottle necks are studied
   • Costs
     • Incremental stage
       • Analysis
         • Good estimates
     • Cost reductions
   • Reduction of risk
     • Time is susceptible to change
       • Is reduced

4. Configuration Management

   • Manage life cycle of the system
   • Attain and maintain product integrity
