This report proposes two electricity pricing strategies for the Major of an American town of 16,000 people. An implementation with the AIMMS software is pres...

Various constrained problem formulations for the optimization of an electro-thermal wing anti-icing system in both running-wet and evaporative regimes are pr...

In many large engineering design problems, it is not computationally feasible or realistic to store Jacobians or Hessians explicitly. Matrix-free implementat...

In this paper, we introduce a new measure of social fairness based on unfairness feelings of the players involved in an allocation problem, e.g., cake-cuttin...

The distance signless Laplacian of a connected graph \(G\) is defined by \(\mathcal{D}^\mathcal{Q} = Diag(Tr) + \mathcal{D}\), where \(\mathcal{D}\) is...

Proximity \(\pi\) and remoteness \(\rho\) are respectively the minimum and the maximum, over the vertices of a connected graph, of the average distance f...

Given a linear program (LP ) with m constraints and n lower and upper bounded variables, any solution \(x^0\) to LP can be represented as a nonne...

In this article, we solve the pickup and delivery problem with time windows and last-in-first-out (LIFO) loading. LIFO loading minimizes handling while unloa...

Global asset optimization aims to simultaneously optimize mine production schedules, destination policies and the various processing streams in order to maxi...

This paper addresses the optimization of long-term mine production schedules, building upon a previous stochastic integer programming (SIP) formulation based...

Traditional short-term production planning is carried out in two separate sequential optimizations, typically based on mixed integer programming formulations...

Mining operations are highly affected by risk, commodity price and geology being acknowledged as the most relevant risk factors. Considering these uncertaint...

The optimization of open-pit mine production scheduling (OPMPS) is an intricate process due to its size and uncertainty of key input parameters. Over the las...

This paper presents a distributed and dynamic programming framework to the mining rate target tracking of multiple mines under financial uncertainty. A singl...

This paper presents a metaheuristic solution to the optimization of open pit long-term production scheduling with a stockpile and geological uncertainty. The...

The use of spatial high-order statistics has been previously proposed as an alternative to introduce richer information about complex spatial patterns in the...

The production scheduling of an open pit mine determines the optimal extraction sequencing that significantly impacts a mine's life as well as net present va...

Mining complexes contain multiple sequential activities that are strongly interrelated. Extracting the material from different sources may be seen as the fir...

We propose a new large scale optimization model, named TS_LAP, for the locomotive assignment problem (LAP), which relies on train strings or consist travel p...

The buffer sizing problem in unreliable production lines is a complex combinatorial optimization problem. In the formulation of the problem, the system consi...
