Towards integration of supply chain, manufacturing/production and investment decision making, this paper presents a hierarchical model architecture which contains six sub-models covering the areas of manufacturing control, production operation, design and revamp, production management, supply chain and investment decision making. Six types of flow, material, energy, information, humanware, partsware and capital are clasified. These flows connect enterprise components/subsystems to formulate system topology and logical structure. Enterprise components/subsystems are abstracted to generic elementary and composite classes. Finally, the model architecture is applied to a management system of an integrated suply chain, and suggestion are made on the usage of the model architecture and further development of the model as well as implementation issues. 展开更多

The development of complex products is essentially concerned with multidisciplinary knowledge. Running on Internet, integration based on muhilayer federation architecture and dynamic reuse of simulation resources are the major difficulties for complex product collaborative design and simulation. Since the traditional Run-Time Infrastructure (RTI) is not good at supporting these new requirements, an extended high level architecture (HLA) multilayer federation integration architecture (MLFIA), based on the resource management federation (RMF) and its supporting environment based Service-oriented architecture (SOA) and HLA (SOHLA) are proposed, The idea and realization of two key technologies, the dynamic creation of simulation federation based on RMF, TH RTI, an extensible HLA runtime infrastructure (RTI), used at Internet are emphasized. Finally, an industry case about multiple unit (MU) is given. 展开更多

The paper deals with Jan Patocka's considerations on architecture. It presents Patocka's concept of space as the union of two sensory fields, the kinaesthetic-tactile and the visual, and it emphasizes that this union is considered as the "primordial architecture". According to Patocka's view, the material architecture is only a consequence of the primordial architecture. The paper also follows Patocka's idea of the "sacral transubstantiation". Patocka argues that, traditionally, the construction of a work of architecture is considered as dependent on favourable conditions, on divine consent with such a construction and the movement of divine powers into constructed work. The origin of architecture is thus religious. The paper considers the relations and differences between the sacred and secular architecture. It highlights Patocka's idea that both sacred and secular architecture open a certain world, even thought, the status of the world of sacred architecture differs considerably from that of the world of secular architecture. 展开更多

The purpose of this study is to find "the new theory" in the process of having quality "form" in architecture field which is usually visualized by the ruler through his ideology of his architectural work which is created by his architects. The study is about an urban design in architectural field related with space-power-knowledge. To reveal the meaning of the architecture objects is need to analyze the architectural object "form" as the culture-material, and to reveal the meaning of the objects through the hidden things related to the presence of the metaphysical data. To find "the new theory" used "grounded theory research", the method is part of qualitative research which refers to Glaser and Strauss. The achievement study is finding the idea of"architecture stage" of the ruler, represented by Soekamo as the first Indonesian President. Through visual observation and spatial experiences in his several architectural works concerning the "Project's Lighthouse" as his architectural work in Jakarta in the 1960s the idea of connectedness was found. He composes his architecture's work by inserted the "architecture drama analogy" as metaphor for representing himself and his ideologist by exploring the Javanese Ancient's as the basic design in the modem architecture at that time the east meet west. 展开更多

The author constructs a family of manifolds, one for each n ≥ 2, having a nontrivial Massey n-product in their cohomology for any given n. These manifolds turn out to be smooth closed 2-connected manifolds with a compact torus Tm-action called momentangle manifolds ZP, whose orbit spaces are simple n-dimensional polytopes P obtained from an n-cube by a sequence of truncations of faces of codimension 2 only(2-truncated cubes). Moreover, the polytopes P are flag nestohedra but not graph-associahedra. The author also describes the numbers β^(-i,2(i+1))(Q) for an associahedron Q in terms of its graph structure and relates it to the structure of the loop homology(Pontryagin algebra)H_*(?ZQ), and then studies higher Massey products in H*(ZQ) for a graph-associahedron Q. 展开更多
