Project progress dynamic regulating method considering resource constraint

Abstract

The invention discloses a project progress dynamic regulating method considering resource constraint. The project progress dynamic regulating method aims as the problems that the construction period requirements are too ambiguous and harsh, the resource constraint and progress fusion are not tight, the progress planning and regulating are complicated under resource constraint and the like in a critical chain method, and provides a progress optimization model improved on the basis of a construction period-cost linear model, considers the estimation of a construction period-cost relationship in actual project execution, improves an objective function to a non-linear expression, converts the resource combination criticality and project completion probability into constraint on a construction period, and regards a buffer zone of the critical chain method as adjustable construction period constraint. The progress optimization result of example simulation verifies the effectiveness of the project progress dynamic regulating method, and the project progress dynamic regulating method can better deal with the situations of progress deviation or resource change.

Description

technical field [0001] The invention relates to a method for dynamically controlling project progress considering resource constraints. Background technique [0002] Nowadays, due to the continuous development of productivity, production and construction projects involve more and more resources such as manpower, materials, mechanical equipment, and technology. The cross constraints of these resources will have a greater impact on the progress of the project. Therefore, considering resource constraints and dynamically adjusting the project progress in real time has become an urgent technical problem to be solved. With the help of a reasonable method of project schedule dynamic regulation will create higher social value. [0003] The critical chain method (Critical Chain Method, CCM) is a technical method proposed for the dynamic control of the project schedule. It uses the buffer zone to realize the dynamic control of the project schedule. Calculate the critical path by cal...

Problems solved by technology

However, most of the existing relationship forecasts do not consider the impact of resource changes on costs

However, in most actual application scenarios, it is obviously unreasonable to express the construction period-cost mathematical relationship linearly in the whole process of project management, which will cause a large deviation between the adjusted schedule and the actual value
