Extremal chemical graphs of maximum degree at most 3 for 33 degree-based topological indices
We consider chemical graphs that are defined as connected graphs of maximum degree at most 3. We characterize the extremal ones, that is, those that maximize...

We investigate the impact of information asymmetry regarding the producer of remanufactured products on the decisions of a manufacturer and an authorized r...
BibTeX reference
Blending problems occur when different components are mixed to form an end product. The recipe typically has some flexibility as long as specific quality con...

Integrating Optical Transport Networks (OTNs) into multilayer Elastic Optical Networks (EONs) enhances data transmission efficiency but introduces significan...
BibTeX reference
Population growth and city sprawl have been driving increasing amounts of traffic congestion in multiple major cities worldwide. In this scenario, developing...

The procurement of freight services is an important element for the supply chain management of a shipper (i.e., a manufacturer or retailer) that sources tran...
BibTeX reference
We propose a dynamic stochastic game model to assess the value of restrictive clauses in private loan contracts. Restrictive clauses are used by lenders to m...

to account for tail risks associated with an uncertain loss. With limited data, the empirical entropic risk estimator, i.e. replacing the expectation in the ...
BibTeX reference
We propose some diagonal Hessian approximations of the least-squares nonlinear function. We use suitable diagonal matrices that carry some information of the...
BibTeX referenceMERCURY: A fast and versatile multi-resolution based global emulator of compound climate hazards
High-impact climate damages are often driven by compounding climate conditions. For example, elevated heat stress conditions can arise from a combination of ...

In the multi-commodity two-echelon vehicle routing problem with time windows (MC-2E-VRPTW), first-echelon vehicles transport goods from depots to satellites...
BibTeX reference
Planners in different industries use optimization software for decision-making. In numerous practical applications, these optimization tools are often not re...
BibTeX referenceThe feasibility of ultra large-scale distributed networks in symmetrical network typologies
This study investigates the feasibility of large-scale distributed networks. The core focus of our research is the impact of multi-hop communication on point...

This paper addresses the Integrated Electrical Drill Rig Dispatching and Drilling Coordination Problem (IDRDCP) in open-pit mining operations, combining mach...
BibTeX reference
The routing-and-driving problem for plug-in hybrid electric vehicles (PHEVs) is an extension of the vehicle routing problem with time windows, where routing ...
BibTeX referenceOn the clique decomposition impact to the optimal power flow semidefinite relaxation solve time
Managing intermittent generation in electric power systems with high penetration of renewable sources of energy presents major operational challenges. Faster...
