The Study Of Method In The Synergy Distribution Of Project Construction Design-limited

At present, quota design research mainly emphasized its importance, and the current limitdesign theory has not given the quota design value distribution method and technology, whichin practical applications often lack of interoperability. If according to conventional methods,namely pure reference to the similar project technical and economic information, investmentestimation according to the similar engineering investment proportion to each unit, but thiskind of method and the actual situation often are neglected, because the project cost will varywith time, place of engineering and technology of the different conditions and differences.Only with the similar project investment ratio as reference may not accurately reflect the costof each component of the reasonable relationship. So the quota design and operation method ofin-depth research, has the important theory significance and the practical significance.This paper mainly studies the construction of the engineering project design stageconstruction cost allocation, and take it as the core to establish a mathematical model. In thecourse of the study, will influence the design limit of two factors (i.e. project function andsocial labor consumption) were analyzed, and deduces the functional reliability andengineering cost function and establishes corresponding construction project of comprehensiveevaluation of technical economy effect relation, the two formula for collaborative allocationmethod the model provides a key constraint conditions, the degree that the rationality ofconclusion and accuracy.Engineering cost index allocation mainly from the multidisciplinary design optimizationtheory, on the basis of this, introduces the function reliability quantized value method. For theconstraint condition and establish a perfect collaboration allocation method, also describes thedesign cost tree related content.Finally, through the staff of a college in the affordable housing project, demonstratescollaborative allocation model of operating process, and summarizes the research conclusionand future prospect.
