A New Automobile Global Manufacturing System: Utilizing a Dual Methodology


Authors: Kakuro Amasaka
Pages: 51-58
DOI: doi.org/10.32861/sr.83.51.58
Abstract
In this study, by predicting the form of next generation automobile manufacturing, the author hereby establishes a “New Automobile Global Manufacturing System” (NAGMS) utilizing new total linkage a “Dual Methodology” surpassing JIT. Specifically, NAGMS contains a hardware system with five core elements “TDS, TPS, TMS, TIS & TJS”, and a software system with two core elements “Customer Science Principle (CSP) and Strategic Stratified Task Team Model (SSTTM)”. Actually, to realize global manufacturing, the author, therefore, develops a high linkage model “Advanced TDS, TPS, TMS, TIS & TJS”. The validity of NAGMS is then verified at Toyota and others.

Abstract
The paper discusses geopolymerisation which is a chemical reaction within an alkaline solution as well as a solid reaction of both aluminium and silicon. It highlights the origin of silicates, pozzolanic composite or alumino-silicates that could be melted within alkaline solution that may be utilized as a source of geopolymers creation. Materials that possess plenty aluminium, silicon and others such as metakaolin, microsilica, pozzolanas, ashes, red mud, kaolin clay and slags can be used as raw materials with the activators to create geopolymers. Also geopolymer end product after the exothermic procedure carried out via oligomers, as well as three stages of geopolymerisation which are suspension, when hard or solid alumino-silicates matter and stuff is dissolved because of the occurrence of water together with alkali activator. After jettisoning a small quantity of water, the reorientation outsets, and then the cluster atoms take their position in the structure. In the course of the solidification at 200C (twenty Celsius degree) or higher temperature of roughly 10000C, the water (H2O) is almost absolutely jettisoned and the material displays his final look.
