Applied Study Of CIM In Material Management Of Building Engineering

Application fields of CIMS and it's related technologies have become more and more wider, especially in manufacturing industry, but they are not paid enough recognition in construction industry. And that, drastic competition and laggard management actuality make construction industry is crying for adopting CIMS and its related technologies. In this paper, based on this background mentioned above, combining the research achievement and engineering practice of implementation of CIMS Application Reference Site sponsored by science committee of Chongqing City ——"applied study of CIMS in quality management of building engineering (NO.6070)", the author studies on the technology of material management.After analyzing the actuality of material management system and the need to apply CIMS in building industry, the design of collective scheme of CIMS engineering in material management of building industry and the design of planning and decision-making subsystem and quality management subsystem are studied in this paper.At the point of design the collective scheme of the CIMS engineering in material management of building industry, the deficiency of material management system in building industry in existence have been analyzed, along with the aim of applying CIMS in building industry. Based on that, the author bring forward that the CIMS engineering in material management of building industry should be composed by seven subsystem——synthetic query subsystem, planning and decision-making subsystem, system management subsystem, quality management subsystem, finance management subsystem, stock management subsystem, storage management subsystem, and draw the system configuration diagram, the function tree and the function model diagram of A0 and A-0 of the CIMS engineering in material management of building industry.At the point of design of planning and decision-making subsystem, to make engineering change in time and convenient, planning and decision-making subsystem will be composed with analyzing and decision-making module, material requirements planning module, and material stocking planning module because material requirements changes frequently along with the change of environment. Workflows of the three modules are also presented in this paper. In addition, the problem about datainput of material requirements planning is discussed also, namely how to gain the time and amount of required material basing on double-symbol network diagram of engineering item.At the point of design of quality management subsystem, the function model and information model of quality management subsystem are traced out in this paper. And the author also design the system configuration, the database constitutes of quality management subsystem and implode its software system.At last, the network system configuration, imploding tools and managing element of CIMS engineering in material management of building industry are discussed in this paper.Generally speaking, the technology of CIMS engineering in material management of building industry is systematically investigated, closely combining the practice. The combine of theory and practice is the target of this paper.
