Advanced simulation of tower crane operation utilizing system dynamics modeling and lean principles

Tower cranes are one of the major equipments used in the construction of high-rise buildings. Simulation is an effective tool in modeling complex construction operations such as tower crane lifting. Lean principles combined with a simulation module can significantly reduce the cost and improve time management of construction. This paper presents an integrated system dynamics model with Lean concepts to simulate tower crane operations. This paper also presents a new type of tower crane with the following innovative futures: 1) two jibs; 2) propellers to swing the crane; and 3) wireless video monitoring technology. This double-jib crane will potentiality improve the productivity of the crane operation. A case example is presented and the results of the model are used to illustrate the advantages of utilizing a double-jib crane in the construction process. The results indicate that advance simulation techniques can minimize the resource requirements of crane operation.
