Construction process simulation allows producing a virtual copy of an existing or planned construction site. The detailed analysis of construction processes and construction logistics with the support of simulation models creates a better understanding of the performance defining aspects. In many construction sites, the actual performances lag behind the planned levels. This is due to the insufficiency of planning instruments. The authors have performed an in-depth analysis of the internal supply chain of an actual tunnel construction project. While the presented study has focused on the inner outfitting of the existing tunnel, similar work has been done for the excavation processes by the authors. The paper reviews the role, simulation plays for construction planning and investigates the benefits of simulation as a step towards increased automation levels.

“…The tool is also capable of calculating a project's costs, if the relevant unit price information is available. The SPS for Tunneling was tested and applied several times by the city of Edmonton (Er et al., ; Van Tol et al., ; Fernando et al., ; Al‐Battaineh et al., ). Furthermore, it can be embedded in a High Level Architecture (HLA) to cooperate with other simulation models (Yang et al., ; Al‐Bataineh et al., ).…”

Production in mechanized tunneling frequently encounters disruptions due to sensitive process interdependencies. Reasons can be technical failures, insufficient capacity dimensioning, organizational deficiencies, or sensitive supply chains. These unproductive times could be reduced by an adequately designed project setup including logistical aspects. Therefore, possible disturbances must be identified and analyzed in detail. Based on this investigation, the machine and logistics setup can be changed to cope with unforeseen events. We present a modeling and simulation approach to analyze production and logistic processes of mechanized tunneling processes in a transparent and understandable way. The system is formalized in the modeling standard SysML. Thereby, we consider relevant system elements and process interdependencies to assess the effect of disturbances and to identify bottlenecks. We distinguish three kinds of disruptions: (i) technical failure of main elements related to the production processes, (ii) issues resulting from an insufficient supply chain, and (iii) cascading disturbances. The implementation in a simulation environment and the processing of relevant input data are presented hereupon. The presented approach is then illustrated by means of an application example based on a completed metro project. Three extending simulation studies quantify the impact of the identified disturbance categories.

“…In addition, Simphony provides the opportunity to modify the production process, adjust the parameters of the model, and examine the results by running the simulation as many times as needed. Simphony has been used within the construction domain for many purposes, such as project duration forecasting, resource utilization, and general decision making support (Moghani, et al, 2011;Farrar, AbouRizk and Mao, 2004;Fernando, et al, 2003;AbouRizk, 2010).…”

Bolstered by significant productivity improvement in manufacturing technology, the construction paradigm has shifted toward industrialized construction methods, such as modular construction. Modular construction has benefitted from the long term development of the manufacturing technologies and core techniques used in the assembly production lines of construction prefabrication plants.Lean production is a methodological approach for assembly line production that aims to eliminate waste, minimize inventory, and maximize production flow.This research proposes implementation of lean concepts through combined discrete-event and continuous simulation approaches with the aim of increasing the productivity of a modular construction element. The proposed model incorporates a simulation of the system reliability by modeling various problems detected within the production line, such as double-handling. Applying continuous simulation facilitated attaining optimal threshold by detecting the inventory level. In addition, improvements are implemented within the model, such as introducing advanced alternatives for the automated stations and adding parallel stations to increase productivity. The effect of proposed production line improvement, along with each station improvement are examined and investigated.
