Round-table talks : Research and development of systems science and technology−185−Synthesiology - English edition Vol.4 No.3 (2012) people who excelled at the time thought and made things in terms of systems very routinely. However, they did not advocate, “This is the system,” and it was not communicated. At the time, the word “system” was used as in the context of something like the “computer system,” and the use in the sense of systemic way of thinking did not diffuse. I don’t think it was incorporated well in education. KimuraThe word “system” was not really used very often. However, the shinkansen and NTT’s DIPS were very state-of-the-art. The 10 million ton integrated production of iron and steel was the victory of systems technology, and stood at the top of the world. Although there might have been arrogance, we need to work hard to achieve them again. AkamatsuWhen looking at the past to learn, we reduced our challenges to elements since we thought we were winning by elemental technologies. Unless we state that the challenge is the system, nothing can be solved even if we emphasize problem solving. Strategic research for systems construction is necessary – Do not proceed blindlyKobayashiThat the “challenge is the system” is a very good analysis. When you say system, there are systems with which we design certain structures from the beginning and then built them robustly, and there are those where partial optimization is done in the autonomous decentralized style. These differ according to how the issues are solved. Are there many methodologies for designing the system?KimuraWe should not fall into partial optimization. If you are autonomously decentralizing, you must intend to design a system of autonomous decentralization from the beginning.We proposed that the “research for systems construction strategy is necessary”. This was proposed late in the discussion of the Systems Science Section, CRDS, and is an essential factor lacking in Japanese science and technology. I am a researcher in the field of control, and in designing a control system, we don’t blindly implement the controller for a large plant. The plant is thoroughly analyzed in a model-based study, the model is created, the model is put in the computer, the parameters are optimally designed, the simulations for whether these are okay are done repeatedly, and finally, if all goes well, it is implemented. That is the cardinal rule.However in Japan, demonstration research is started right away. While the basic research for elemental technology is done thoroughly, people think that basic research is not necessary for systems. Of course, demonstration research is would essentially be a material industry. I think this thought was prevalent in other industries as well. AkamatsuAlthough the value was in the manufacturing system, people emphasized the elemental technology of the “product”, and thought that the value lay therein. KimuraThere was no room to recognize our arrogance and we failed to capture the reality and prepare for the next. People thought that Japan would continue to rule the world, and also thought that the Japanese style management conquered the world.When the Japanese industry shiftsKobayashiI’ve heard that the manufacturing industries have been gravely hit by this earthquake and disaster, With the Oil Shock in the early 1970s, the rapid economic growth of the heavy industries led by iron, steel, and shipbuilding ended, and the main players of industry shifted to automobiles and electric industries. With the current state of automobiles, we don’t know whether the EV (electric vehicle) will become the mainstream in the future. I feel that the Japanese industry must make the shift after the East Japan Earthquake, and this may be the time to reexamine systems science and technology once again. AkamatsuWhen something goes wrong, people tend to seek out the culprit of the supposedly man-made disaster, but that is very dangerous. Reducing the matter to a personal fault is similar to the thinking of reducing the matter to an element. As we recover from the earthquake, we are not looking at the situation systemically if we reduce the problem to who made the mistakes.You mentioned the shinkansen system as an example where the systems technology truly shined. Mr. Shima, the head engineer of the former Japan National Railways, managed the technological development of the shinkansen. He said, “We did only ordinary things. One must think ahead and thoroughly.” I think he thoroughly thought about what things were needed to run the shinkansen and carefully built the needed things. The Dr. Motoyuki Akamatsu
