Research On Multi Project Construction Schedule Management Of H Company Based On Critical Chain Technology

With the rapid development of society,the size of the construction industry is gradually increasing.As a typical project management enterprise,construction enterprises are facing huge project management challenges.In the field of construction engineering,traditional project management models such as Gantt chart,critical path method and plan review technology are often used to prepare the initial schedule.The traditional project management mode has made great achievements in single project management,but for the construction enterprises with multi project management as the core of production and operation,project delays often occur.The traditional Gantt chart,critical path method and plan review technology cannot solve the problems about "safe time","bottleneck resources","multi project coordination",and can not meet the project management requirements of modern construction enterprises.Therefore,this article uses the critical chain technology proposed by Israeli physicist Dr.Goldratt,which introduces constraint theory into projects and applies it to project management.It can solve the difficulties faced by enterprises in multi project management,and has certain theoretical and practical significance in enterprises that focus on project management as their business activities.This paper first introduces the characteristics of project management in construction enterprises,introduces the application scope and application defects of traditional Gantt chart chart,critical path method and plan review technology,and discusses the advantages and disadvantages of key chain technology based on constraint theory.Then,taking the example of multi project management in H company as the object,analyze the reasons and influencing factors that led to project delay in H company,and then use critical chain technology based on constraint theory to manage project progress to make up for the shortcomings of traditional project management methods.The key chain technology used in this article is a combination of constraint theory and uncertainty analysis,which is not only an effective project management technology,but also an advanced project management concept.This article introduces the research method of critical chain technology and designs a multi project schedule management process based on critical chain technology for H company.Based on the project characteristics of Company H,consider the bottleneck resources between projects,and effectively utilize the bottleneck resources of Company H through the identification of critical chains and the setting of buffer zones.After research,it has been found that in actual projects,the project/process duration influenced by bottleneck resources and process dependency logic is the true project/process duration.Key chain identification takes into account the conflicting use of bottleneck resources,while buffer establishment reduces the "safety time" added in the early stages of the project.This measure not only reduces the construction time of the project,but also takes into account the impact of human factors on schedule management,thereby improving the effective output of the enterprise,reducing project and enterprise operating costs,and thus improving the overall operational efficiency of the enterprise.It has practical significance.
