This paper describes a stochastic simulation model to optimise the location of a single tower crane. The model presented reconstructs the process of demand and supply of materials taking place on site, and simulates a crane able to satisfy requests for deliveries, by determining average transport time for each request as a criterion. The proposed model not only reflects the influence of the intensity of material flow between the service points, and the velocity of boom slewing and trolley movement, already achieved by the earlier models, but also takes into account balance paths, together with types of requests and the manner of hook movements, as being significant influences on optimum crane location, in order to provide a more accurate representation of the real world compared to other models. Results indicate that approximately 20-40 percent of crane travelling time in horizontal plane car1 be saved, depending on type of crane, skill of crane operator and site conditions, if located at the position recommended by the model.
