It will be seen from this that steel industry is an important indicator of a nation’s development. Taiwan’s current largest steel company owns in total six blast furnaces, in which the average output of molten iron is about eight thousand ton per day. It is the vital source for providing a variety of steel-manufactured products. The blast furnaces are running continuously twenty-four hours, in which once furnace shut down it will influence the output of molten iron. However, this important equipment needs maintenance. Thus, periodic examine and repair plan becomes critically important. Blast furnace periodic maintenance plan has the following features: short duration of the project, and many schedules and high risk. The project managers are faced with how to use project management approach to finish the periodic maintenance plan under the limited resources within the shortest timescale, and to achieve the required quality, which is really a big challenge of project managers. This study aims to achieve the better performance of using project management approach by applying critical chain project management, via the example of C iron and steel company, to the scheduling program of blast furnaces’ periodic maintenance plan. The purpose of critical chain project management is mainly through the resources control. Firstly, it calculates each activity’s required time based on activity actual needed time to reduce the activity time, and then to add up all activities’ saving time to project buffer time, which also considers the feeding buffer issue. Secondly it uses resources leveling technology to handle the resource-conflicting activities. Lastly, it monitors the consuming level to achieve the purpose of controlling the project progress. Because the use of buffer is a post hoc event, it is short of early warning function. If combined with earned value management’s early warning mechanism, it can provide project manager more time to cope with project problems. The results in this case study show that after applying project management to periodic maintenance plan, the performance of cost and schedule has enhanced significantly, which can provide a reference for planning schedule related managers.
