  17. Systematic Problem SolvingInfinite Final Solution Which approach is preferable ? 2nd Stage Current Stage Infinite Final Solution You might lose the way. 1st Stage You might be embarrassed by moving targets. You might be required a little bit more effort and imagination. Infinite Final Solution 1st Stage (F-1)th Stage (F-2)th Stage Current Stage You can easily find the way.

  18. Systematic Problem Solving Technology Evolution S-curve Every technology evolutes in S-curve. Technology transfer is inevitable to reach higher degree. Degree of ideality To minimize cost To increase reliability To increase efficiency To increase performance To operate stably To be operable (5) Retirement (4) Mature (3) Infant / Growth (2) Birth Time (1) Idea Focus of invention is dependent on S-curve position.

  19. Conclusion • Two achievements were introduced: • BWR Core Performance Calculation System • for on-line monitoring of power distribution • in reactor core by physical-model-based simulation program • ABWR Instrumentation and Control System • for enlargement of automatic operation, and • digitalization of control console • Two approaches of Systematic Problem Solving • in Technology Innovation were proposed: • to search from GOAL to START • to recognize Technology Evolution S-curve
