Today's traditional views alone can not meet the needs of managing civil engineering projects. Therefore, the use of modern managerial approaches can be largely controversial. The first step towards achieving this goal is to understand the types of projects in terms of line or network, the difference between managing a project with multi-project management and project management and implementation methods. In this research, the critical chain management approach has been used instead of the critical path method to provide a more practical timetable. In order to overcome uncertainty, the proposed method of fuzzy numbers in terms of the definite time of activity and knowledge of experts is used to model uncertainty over the duration of the activity. The proposed method, instead of replacing the initial deterministic scheduler with the fuzzy set time schedule, still holds the definite time schedule and simply arranges the project buffer to deal with uncertainty. The size of the project buffer is determined using calculations on fuzzy numbers. Also in order to overcome the risk in the case study, this study considers an average risk factor to meet the needs of the project buffer. However, changing the risk factor in different high, medium and low risk situations will have little effect on buffer size. In this study, in order to evaluate the model presented in this study, several linear-repeater construction projects were simultaneously studied and planned.
