Abstract

The Last Planner System (LPS) and Location-Based Management System (LBMS) are both lean planning and controlling tools. A combination of these systems would bring much greater benefits than stand-alone implementations. However, previous research attempting to combine these methods has not been on sufficient level of detail for actual implementation. The goal of this research is to develop a combined workflow for master planning, phase planning, look-ahead planning and weekly planning. The workflow is demonstrated through the use of a simple example from a case study project. Master scheduling clearly belongs to the domain of LBMS; time and weekly planning is clearly within the domain of LPS. Phase scheduling can include components from both systems but integration is straightforward. The biggest opportunities for improvement exist in progress tracking, forecasting, control action and look-ahead planning phase where LBMS and LPS both have important independent contributions and their combination is not trivial. The paper attempts to better define the inputs and outputs of each system in each phase to come up with a unified solution. A case study example will help practitioners implement the combined method.
