Order batching and sequencing problem
WebNov 16, 2024 · The Order Batching and Sequencing Problem (OBSP) involves the process of collecting orders in a warehouse by grouping orders into batches with a maximum fixed capacity. In the context of the OBSP, each order has a certain due date, i.e., it must be collected before a specific time. Otherwise, it has associated a tardiness penalty. WebJun 16, 2024 · We evaluate the performance of the proposed DRL approach by comparing it with several batching and sequencing heuristics in different problem settings. The results …

Therefore, this study proposes a hybrid heuristic combining a genetic algorithm and variable neighborhood descent (GAVND) to resolve OPPSP-Het. As aforementioned, one of the main contributions is to adapt and …
WebDistinguished from the past studies, a comprehensive nonlinear mixed integer optimization model is developed to simultaneously determine three decisions, including order batching, batch sequencing, and picker׳s routing, under the consideration of the minimum total tardiness of customer orders. The IOBSRP can be proven as a NP-Hard problem. Weborder batching have also been studied for decades and classical solution approaches for order batching problems can be distinguished into priority rule-based algorithms, seed algorithms, saving algorithms, and data mining ap-proaches [13–16]. Related batching operation is known as batch scheduling problem, which needs to determine op-
