Order batching and sequencing problem
WebJun 26, 2024 · The orderbatching problem in warehouses is investigated and two groups of heuristic algorithms are evaluated: the Seed algorithms and the somewhat more complex (and CPU time consuming) Time Savings algorithms. 258 A continuous estimation of distribution algorithm for the online order-batching problem WebA mathematical model of the problem is introduced that allows for solving small problem instances in reasonable computing times. For larger instances, a variable neighborhood descent (VND) algorithm is presented which includes various neighborhood structures regarding the batching and sequencing problem.
