“…This method has been widely used for utilization of container relocation problem by Jin, Zhu, & Lim [14] and Zhu & Lim [15]. Look-ahead method aims to take into account and react to changes in real-time systems [16]. Hence through this method two to five trucks behind the queue before it reaches the point for dispatching, the trucks have to know in advance the loader point which will be addressed based on the needs of each shovel to transport and based on a production target that has been set.…”

ABSTRACT:Material transportation in open-pit mines area contributes to 50% of the operating costs. Therefore, efficiency on the material transportation, specifically in truck dispatching problem needs to be done in order to get the best dispatching rules for the allocation of trucks and loaders. This research uses look-ahead algorithm approach as a new method to solve truck dispatch problem in open-pit mines area. The proposed approach was developed by simulation and optimization model in solving the truck dispatch problem using real data-situation. The dispatching result aims to answer the question where and when should a truck go so that could maximize the number of production and provide significant operating cost savings to the mining industry. This study uses a discrete event simulation to test several scenarios methods of truck dispatch, including LP-Gap, the percentage of LP-Gap, multi-stage algorithm and look-ahead algorithm. The results of the research shows that the look-ahead algorithm scenario gives the highest result with the number of production, productivity of loaders, productivity of trucks with block and without block; 43,533 ton, 64.44%, 80.53% and 63.47%.

“…For instance, from an array of GPS readings coming from a receiver attached to a truck, we need to identify when the truck starts traveling to the dumping location or how long it has been in a queue before it is serviced by a loader. Although a similar concept has been proposed before (Song & Eldin, 2012), the proposed rules are restricted to one type of equipment, i.e. trucks, and several states, such as out of service, have not been covered.…”

“…time and cost, and also in order to make simulation results more realistic, the assumptions made at the point of the model design need to be constantly modified and attuned based on the actual state of the operation. Consequently, some research has been conducted on a mechanism to dynamically monitor the trend of changes in the model parameters and adapt the simulation model accordingly in real-time (Hammad & Zhang, 2011;Lu, Dai & Chen, 2007;Song & Eldin, 2012;Akhavian & Behzadan, 2012).…”

Simulation techniques have offered significant boosts toward a cost-and-time-optimized planning of construction projects by enabling project managers to effectively comprehend the behavior of projects. Using historic data from projects of like nature, simulation considers uncertainties involved in a project through accommodating the stochastic modeling parameters. However, the heavy reliance on the statistical data and not taking into account the context-specific features of the project cause the degradation in the realism and accuracy of the simulation models. Similarly, the extent to which a historic pattern could be retrofitted to new projects will decrease in line with the growing uniqueness of the projects and the novelty of construction methods. Furthermore, the existing real-time simulation frameworks are not capable of distinguishing the transient environmental changes, with minimal long-term impacts on the productivity, from the influential changes that will greatly impact an operation. In addition, existing simulation tools are devoid of location awareness, resulting in the inability to consider safety threats in their representation of the project. To address these issues, this research proposes a framework based on the integration of new tracking technologies used in Automated Machine Guidance (AMG) with simulation-driven 4D modeling methods. The proposed framework automates the adjustment of the simulation model based on the updated data from the site, and thus transforms simulation from a predictive tool used at the planning phase to a proactive monitoring platform usable throughout the planning and construction phases. A prototype is developed to test and demonstrate the effectiveness of the proposed approach.

“…This procedure is known as reactive scheduling. Currently, the adaptation of construction schedules is a manual, time consuming, error prone, and therefore poorly supported process (Song and Eldin 2012). In practice, there exists a high demand for efficient and userfriendly concepts, which can integrate and evaluate actual data as well as compare and update schedules.…”
