A Method of System Model Improvement Using TRIZ Function Analysis and Trimming

  • Nikolai Efimov-Soini
  • Kalle Elfvengren


This chapter presents a method of system model improvement by means of system complexity reduction, based on TRIZ function analysis and trimming. The suggested method can be used for new development as well as improvement of an existing system. The presented approach is illustrated by an industrial case study.
