“…While addressing the challenges of production flow and ship planning at ports, the available literature directly connected to mining is limited, as highlighted by [5]. Furthermore, most existing solutions for these problems rely on deterministic and single-criteria models, disregarding uncertainty factors [5].…”

“…Hence, approaches considering the underlying uncertainties in the production flow and maritime transportation would significantly contribute to the existing literature. Particularly, the capability of quantifying uncertainty and optimizing systems under mapped uncertainties would be valuable advancements in the field [5] [7].…”

“…The problem of ship allocation in ports has been addressed in several research studies aiming to minimize port operational costs. Various objectives have been considered, such as reducing ship idle time and minimizing penalties for delays [5][11]- [14]. These approaches have ranged from applying single-criterion models to utilizing stochastic techniques and fuzzy sets [15]-[19].…”

This present work aimed at enhancing ore exports and reduce demurrage fines and costs at the port's mining company using multicriteria decision-making models and methods. The global mining supply chain encompasses multiple stages, with port production logistics being a crucial aspect. This stage involves planning the production volume allocated to vessels for transporting ore to its final destination. However, uncertainties arise during this process, including the volume produced and associated operational costs and fines. Traditionally, deterministic monocriteria models have been employed for decision-making, aiming at optimizing outcomes without considering uncertainty factors. Nevertheless, given the nature of the problem, the solution should be implemented within a multicriteria decision-making framework under conditions of uncertainty. The analysis is based on applying the General Multicriteria Decision-Making using <X, F> and <X, R> models to solve multicriteria problems and provide their harmonious solutions. The objective is to assist decision-makers in planning ore production shipped from mining company ports, utilizing a multicriteria system instead of a monocriteria. A case study was conducted at a Brazilian mining company exporting iron ore in their ports, comparing the current monocriteria approach with the multicriteria. The simulated results were compared with the real ports operations. The study concludes that utilizing the <X, F> and <X, R> models, the general multicriteria decision-making approach demonstrated effectiveness in allocating ore production at mining company ports, providing analytical and practical advantages.

Solution procedures for block selection and sequencing in flat-bedded potash underground mines

2021

Phosphates, and especially potash, play an essential role in the increase in crop yields. Potash is mined in Germany in underground mines using a conventional drill-and-blast technique. The most commercially valuable mineral contained in potash is the potassium chloride that is separated from the potash in aboveground processing plants. The processing plants perform economically best if the amount of potassium contained in the output is equal to a specific value, the so-called optimal operating point. Therefore, quality-oriented extraction plays a decisive role in reducing processing costs. In this paper, we mathematically formulate a block selection and sequencing problem with a quality-oriented objective function that aims at an even extraction of potash regarding the potassium content. We, thereby, have to observe some precedence relations, maximum and minimum limits of the output, and a quality tolerance range within a given planning horizon. We model the problem as a mixed-integer nonlinear program which is then linearized. We show that our problem is $${\mathcal {NP}}$$ NP -hard in the strong sense with the result that a MILP-solver cannot find feasible solutions for the most challenging problem instances at hand. Accordingly, we develop a problem-specific constructive heuristic that finds feasible solutions for each of our test instances. A comprehensive experimental performance analysis shows that a sophisticated combination of the proposed heuristic with the mathematical program improves the feasible solutions achieved by the heuristic, on average, by $$92.5\%$$ 92.5 % .
