Integrating Condition-Based Maintenance into Dynamic Spare Parts Management
Dmitrii Usanov, Peter van de Ven, Rob van der Mei
In this paper we introduce a new model where the concept of condition-based maintenance is combined in a network setting with dynamic spare parts management. The model facilitates…
Approximate Dynamic Programming for Real-time Dispatching and Relocation of Emergency Service Engineers
Dmitrii Usanov, Anna Pechina, Peter van de Ven +1
Quick response times are paramount for minimizing downtime in spare parts networks for capital goods, such as medical and manufacturing equipment. To guarantee that the maintenance…
Real-time Dispatching and Relocation of Emergency Service Engineers
Anna Pechina, Dmitrii Usanov, Peter van de Ven +1
Capital goods such as complex medical equipment, trains and manufacturing machinery are essential to their users' business, and thus have stringent up-time requirements. Responsive…
Accounting for model error in Tempered Ensemble Transform Particle Filter and its application to non-additive model error
Svetlana Dubinkina, Sangeetika Ruchi
In this paper, we trivially extend Tempered (Localized) Ensemble Transform Particle Filter---T(L)ETPF---to account for model error. We examine T(L)ETPF performance for non-additive…
Bounds on entanglement dimensions and quantum graph parameters via noncommutative polynomial optimization
Sander Gribling, David de Laat, Monique Laurent
In this paper we study bipartite quantum correlations using techniques from tracial noncommutative polynomial optimization. We construct a hierarchy of semidefinite programming low…
The quadratic assignment problem is easy for Robinsonian matrices with Toeplitz structure
Monique Laurent, Matteo Seminaroti
We present a new polynomially solvable case of the Quadratic Assignment Problem in Koopmans-Beckman form , by showing that the identity permutation is optimal when an…
