Evaluating periodic rescheduling policies using a rolling horizon framework in an industrial-scale multipurpose plant

A Generic Methodology for Calculating Rescheduling Time for Multiple Unexpected Events in the Era of Zero Defect Manufacturing

“…In total, five alternative rescheduling policies are simulated alongside the proposed method and a benchmark scenario that constitutes the ideal scenario, meaning that there are no defects and the only events that occur are new orders. The five rescheduling policies that are used are considered as fixed periodic rescheduling policies because of the simplicity of their implementation in production systems and their high performance (Stevenson et al, 2020). These policies are divided into two categories: rescheduling occurs after every event and rescheduling occurs at certain time intervals.…”

“…These policies are divided into two categories: rescheduling occurs after every event and rescheduling occurs at certain time intervals. In the latter category, four different time intervals are tested: rescheduling twice a day, every day, every 2 days, and every 3 days, of which some are widely used (Stevenson et al, 2020). For each rescheduling policy, 10 individual runs were performed, as explained in section Events Management Algorithm Analysis, to overcome the inherent randomness of generating defects and the randomness of the control factors of the developed method.…”

“…A proactive approach may not foresee all possible disruptive events, even if the original schedule is robust (Barták and Vlk, 2017). Thus, rescheduling has a central role in the robustness of production processes under uncertain conditions (Stevenson et al, 2020). Such production processes need to be as reactive and flexible as possible to minimise interruptions to the production flow (Cardin et al, 2017).…”

“…This adds an extra level of complexity when rescheduling. Therefore, attention should be given to the rescheduling policy used (Stevenson et al, 2020).…”

Surrogate‐based optimization of a periodic rescheduling algorithm

“…The same authors also propose a systematic way to design a periodic rescheduling algorithm, 4 focusing on the interval of scheduling procedures and the horizon length. Stevenson et al 8 study the effect of periodic rescheduling interval to the performance of a multipurpose production plant in different operation conditions. Dong et al 9 present a re‐optimization framework for a maritime inventory routing problem based on a discrete‐time arc‐flow formulation and stochastic simulations to account for uncertainty.…”
