Through visualization, mapping techniques help manufacturing organizations prioritize and guide improvement strategies. For this reason, mapping of the value chain is applied as a method of progress toward lean manufacturing. The purpose of this paper is to illustrate the essence of the material and information flow chart (MIFC) approach, known as value stream mapping (VSM) in the West, to provide a different perspective and understanding and to identify its manner of integration with measurement systems. Metrics complement mapping tools allow the tracking of various stages of an organization's lean journey and continuous improvement (CI). While the time dimension is predominant in performance metrics in lean environments, these metrics do not link the economic factor directly to improvements. The research comprises a case study in which lessons are learned from tool placing and metric determination. Empirical research included critical case sampling and semi-structured interviews, and data were analyzed to compare the conventional Western understanding of VSM with that of a Japanese supplier that learned the principles directly from the source and applied their own version of MIFC. An understanding of the tool based on core knowledge will enable organizations to reevaluate their current measurement systems and choose more suitable ones.
Research and Development program of Advanced Material Gas-Generator (AMG) was initiated in 1993 as a ten year program with a joint investment from the Japan Key Technology Center and fourteen participating Japanese companies. The program objective is to establish basic key technologies for next generation gas-generator using advanced materials, which should have the features of significantly low fuel consumption with reduced weight and size, and should be environmentally acceptable, toward the realization of future industrial, marine and aircraft gas turbines. In the initial phase of AMG program the conceptual study of advanced gas-generator was carried out in order to clarify technical issues and define requirements for each component. Based on the results of conceptual study, Polymer Matrix Composites (PMC), Metal Matrix Composites (MMC), Ceramic Matrix Composites (CMC) and Titanium Aluminide (TiAl) were considered as the candidate materials for the advanced material gas-generator. Then AMG is intensively proceeding R&D for next generation gas-generator using these advanced materials, and is now getting technical fruits. This paper introduces the outline of AMG project and conceptual study, then describes some topics of each R&D themes.
