A framework of enhanced location based management system using simulation models

Critical Path Method is currently criticized for being unable to protect production efficiency. To address the deficiencies of CPM, Location Based Management System was developed. LBMS takes repetitive locations as the computing unit and containers of project elements, through which resources flow in sequences. By incorporating multiple theories and methods in lean construction, it is continuous production that is highlighted in LBMS. To achieve the goal, LBMS needs to collect detailed project data at specific location level, e.g. room and corridor to support related calculation. LBMS by now are mainly used for schedule and costs estimation. However, with the rich data, the potential of LBMS to better accommodate the attributes and interactions of dynamic project elements, e.g. labor, materials and drawings have not been adequately exploited. Fortunately, the current deficiencies can be addressed by applying computer simulations. This paper first introduces LBMS and mainstream simulation methods; then develops a framework that integrates Discrete Event Simulation, System Dynamics and Agent Based Model into LBMS. The framework is formed by a database, a simulation engine and a demonstration tool, which aims to improve decision making by taking individual attributes and interactions and risky processes into consideration. Finally, a case study is introduced to demonstrate how the proposed framework works.
