Emergency Relief Material Distribution Path Optimization Under Multiple Constraints

Applied Sciences
To overcome the limitations of traditional methods in emergency response scenarios—such as limited adaptability during the search process and a tendency to fall into local optima, which reduce the overall efficiency of emergency supply distribution—this ...

Solving the multi-level location routing problem considering the environmental impact using a hybrid metaheuristic

International Journal of Engineering Business Management, 2021
The multi-level location routing problem (MLLRP) is an extension of the capacitated location routing problem (CLRP). MLLRPs are considered a class of combinatorial optimization problems that arise in transportation applications, such as agricultural ...

Data for a meta-analysis of the adaptive layer in adaptive large neighborhood search [PDF]

, 2020
Meta-analysis, a systematic statistical examination that combines the results of several independent studies, has the potential of obtaining problem- and implementation-independent knowledge and understanding of metaheuristic algorithms, but has not yet ...

Self-adaptive large neighborhood search algorithm for parallel machine scheduling problems

Journal of Systems Engineering and Electronics, 2012
A self-adaptive large neighborhood search method for scheduling n jobs on m non-identical parallel machines with multiple time windows is presented. The problems' another feature lies in oversubscription, namely not all jobs can be scheduled within specified scheduling horizons due to the limited machine capacity.

An adaptive neutrosophic large neighborhood search and its application [PDF]

Neutrosophic Sets and Systems
An adaptive large neighborhood search (ALNS) lacks a clear measure for assessing the improvement degree in the new solution, which causes fuzziness and uncertainty in the operator score.
