Compound control system for building cost of light rail projects and control method thereof

Abstract

The utility model discloses a multiplex control system for the light rail construction cost, which comprises the main circuit for the construction cost control (ICS) and the feed-forward circuit (IRCS). The feed-forward circuit (IRCS) is composed of a risk structure module, an information acquisition and processing module and a pre-warning control module. The risk structure module introduces the WBS -RBS risk decomposing tool kit which consists of a work / risk decomposition texture, a AHP analytic approach, a specialist survey technique and a risk factors classification; the information acquisition and processing module adopts a risk information processing tool kit which consists of a indistinct synthesized measuring method, a risk 3D computational model and a CIM control model of memory; the pre-warning control module adopts a tool kit which comprises a AHP method, a specialist survey technique, a scenario analysis, and a risk management guide module. This utility model improves the reliability of the entire construction cost control as well as the reliability and the operability of the feed-forward circuit output.

Description

technical field [0001] The invention relates to the field of urban rail transit, in particular to a composite control system and control method for light rail project cost. Background technique [0002] Urban Mass Transit / UMT mainly includes two categories of subway and light rail. In the field of project cost, the domestic cost control research closest to the technology of the present invention is mainly focused on sequence control and cascade fixed value feedback control system. , its technical mechanism is mainly the migration of traditional engineering cost control methods on UMT projects. The advantages of various UMT cost sequence control systems are mainly reflected in the function group program optimization of cost control such as investment initiation, inquiry review, and interruption at each stage of the project; the advantages of various UMT cost cascading value feedback control systems are mainly reflected in the cost estimation Feedback adjustment mechanism for...

Problems solved by technology

There are many technical risks of the project itself, construction method risks, and natural environmental risks such as geology, hydrology, and climate along the project, which lead to frequent and large horizontal environmental disturbances for cost control. That is to say, compared with input changes, the existing UMT sequence control and cascade fixed value feedback control output show a large delay and inertia
