Simulation-Based Analysis of Surface Jobsite Logistics in Mechanized Tunneling
The construction procedure in mechanized tunneling is affected by a complex interaction of logistic processes. Due to restrictive factors (like limited space on construction sites), a just-in-time delivery of material is required for production purposes. Slight differences of the production rate of a Tunnel Boring Machine (TBM) have huge impacts at the logistical chain. Therefore, logistic management is one of the key factors responsible for the success and profitability of tunneling projects. In this paper, a discrete event simulation model is presented that supports tunneling experts in the planning process and can be applied in the construction phase as a tool for decision analysis. Since each TBM is unique, it has a unique demand for logistic solutions. Therefore, the simulation model is implemented in a modular manner such that it can be applied to a vast number of different projects in mechanized tunneling. The properties of the construction site and the TBM are freely configurable. To show the functionality of the model, a fictive demonstration model was conducted. It illustrates the influence of different logistic processes on the production rate of a TBM as well as the complex interactions of single logistic processes in the supply chain of a construction site.
