Simulation modeling as a decision analysis support tool at the Vancouver Container Terminal Zhou, Aimee Zhiwei


The objective of this research is to find whether replacing tractor/trailers in Vanterm (Vancouver Container Terminal) with straddle carriers will increase the productivity. The productivity is measured in lifts per hour per crane. After a significant productivity increase was demonstrated, the objective of this work was then extended to estimate the optimal number of straddle carriers and to quantify the potential of the straddle carriers in terms of productivity increases. The results of this project will be used to support the decision of purchasing and implementing new equipment for Vanterm. Two discrete-event simulation models were developed as a decision support tool in this project. The models were used to evaluate several transporter allocation scenarios. Statistical analyses were implemented to analyze the results of those scenarios. The results of the simulation gave valuable insight into the vessel operation of Vanterm and provided management at TSI with a strong tool for testing configuration changes to Vanterm without costly investment. In addition to the simulation models, further studies were conducted by testing more scenarios with modified simulation models, applying analytical models and analyzing deterministic models.
