A Study Of The Application To Management Of Project Scheduling Based On Key Chain Technology In ABB Ltd.

In modern business world,the level of project management is one of the most important keys to a successful running of a company.How to develop the level of project management is a significant issue to every company.And the first step is scheduling.Nowadays,contents of projects turn to be more and more complicated and each procedure in a project is more and more difficult to be scheduled.To solve this scheduling,varieties of measures are taken into a project planning.The most common ways are Program Evaluation and Review Technique and Critical Path Method.And based on these two,new method based on Technology of Critical Chain(TOC) is developed.In this paper,a case of ABB Huadian High Voltage Exchanger Ltd.is used to illuminate that how a TOC based project scheduling is carried out.Firstly,the author described the history of project scheduling and basic concepts of TOC.And secondly, the author analyzes how to solve a project scheduling issue with TOC and the three keys steps to application of the TOC method.Thirdly,a project scheduling case of 19 steps in ABB with traditional method is taken into analysis.And shortages of traditional are figured out.With the analysis,a model of project scheduling based on TOC is established.Under the guide of TOC,a new project scheduling is calculated out.In theory,the new result can save about 19 days,compared with the old method.Fourthly,the author analyzes the possibility of application of the new project scheduling and issues that maybe happen in the real schedule.And to solve potential issues,multiple buffers(P.B.& F.B.) are set.With buffers,project scheduling by TOC in this case gets a better result.And finally,the author concludes the whole procedures of this case and gives some thoughts on further development of project scheduling based on TOC.
