In open pit mining, the loading, unloading and hauling system can represent a high percentage of the operating cost. The objective of this document is to provide an overview of the different approaches in the application of simulation models as an alternative applied to open pit mining operations that can help in decision making to optimize resources. It talks about the different types of simulation models that can be applied in mining operations such as stochastic, deterministic and discrete events. The underlying idea of this text is to highlight that with the increase in competitiveness, mining companies are in need of using simulation techniques to reduce costs, time and risks when making decisions, since simulation allows the creation of scenarios that approximate reality. In the end, the document concludes that simulation models are a tool to help in decision-making, for the optimization of resources, increased improvement and efficiency of the processes of loading, transport and unloading in open pit mines.

Hajj Season

Abstract Most mass gathering events have been suspended due to the SARS-CoV-2 pandemic. However, with vaccination rollout, whether and how to organize some of these mass gathering events arises as part of the pandemic recovery discussions, and this calls for decision support tools. Hajj, one of the world's largest religious gatherings, was substantively scaled down in 2020 and it is still unclear if it will take place in 2021 and sub-sequent years. Considering the disease trends and vaccination conditions in the pilgrims’ country of origin, and the operational and logistical aspects of implementing public health measures, Hajj reopening conditions could be very complex. Simulating disease transmission dynamics during the Hajj season under differ-ent conditions can provide some insights for better decision-making. Since most disease risk assessment models require data on the number and nature of possible close contacts between individuals, we seek to use integrated agent-based modeling and discrete events simulation techniques to capture risky contacts among the pilgrims in one of the Hajj major sites, namely Masjid-Al-Haram. In particular, we assessed different scenarios concerning the total number of pilgrims and enforced physical distancing measures. Our simulation results show that a plethora of risky contacts may occur during the rituals. Also, as the total number of pilgrims increases at each site, the number of risky contacts increases, and physical distancing measures may be challenging to maintain beyond a certain number of pilgrims in the site.

Supply Chain Simulation

The field of Supply Chain Management (SCM ) is experiencing rapid strides in the use of Industry 4.0 technologies and the conceptualization of new supply chain configurations for online retail, sustainable and green supply chains, and the Circular Economy. Thus, there is an increasing impetus to use simulation techniques such as discrete-event simulation, agent-based simulation, and hybrid simulation in the context of SCM. In conventional supply chain simulation, the underlying constituents of the system like manufacturing, distribution, retail, and logistics processes are often modelled and executed as a single model. Unlike this conventional approach, a distributed supply chain simulation (DSCS) enables the coordinated execution of simulation models using specialist software. To understand the current state-of-the-art of DSCS, this paper presents a methodological review and categorization of literature in DSCS using a framework-based approach. Through a study of over 130 articles, we report on the motivation for using DSCS, the modelling techniques, the underlying distributed computing technologies and middleware, its advantages and a future agenda, and also limitations and trade-offs that may be associated with this approach. The increasing adoption of technologies like Internet-of-Things and Cloud Computing will ensure the availability of both data and models for distributed decision-making, which is likely to enable data-driven DSCS of the future. This review aims to inform organizational stakeholders, simulation researchers and practitioners, distributed systems developers and software vendors, as to the current state-of-the art of DSCS, and which will inform the development of future DSCS using new applied computing approaches.
