The Lean-Resources Based Construction Project Planning and Control System

Construction project management systems nowadays focus on using the PERT/CPM technique to perform the project time control. However, project managers lack of benchmarking construction operations as the paragons at the construction project planning stage to plan construction project processes, estimate the minimum activity time and allocate lean resources to achieve the aim of time control of a construction project. To help construction project managers perform the construction project process planning and control, this research employs the efficient frontier to develop the leanresources based construction project planning and control system (LRCPPCS). The LRCPPCS uses and analyzes the past history data to find the benchmarking similar construction activities to form the efficient frontiers. Through the efficient frontier, we can penetrate the relationship between resource allocations and activity times. If the result of construction project planning cannot satisfy the customer requirement, the process planning mechanism of a construction project can alter the activity times or resource allocations of a construction project to achieve the aim of a construction project by employing the lean resource allocation. If the delay of an activity of a construction project at the execution stage of a construction project, the process control mechanism of a construction project can modify the activity times and human resource allocations on a critical chain to reduce the delay risk of a construction project. In addition, the approach proposed in this research does not need a lot of the assumptions. Hence, the LRCPPCS can satisfy the practical requirement of construction project management.
