This paper offers a new algorithm to efficiently optimize scheduling decisions for dial-a-ride problems (DARPs), including problem variants considering electric and autonomous vehicles (e-ADARPs). The scheduling heuristic, based on linear programming theory, aims at finding minimal user ride...

Cloud manufacturing task scheduling (CMTS) gains widespread attention in the cloud manufacturing (CMfg) community. At present, most related researches are mainly aimed at task-oriented scheduling and there are few researches considering user’ characteristics, like user preferences. In this...

The purpose of this study is to review energy-efficient scheduling efforts in job shops and its inclusion of uncertainties in the literature. This study carries on efforts of previous review works, with energy-efficient job shop scheduling published in 2022, until the end of October of the same...

The geographical dispersion of collaborative factories may provide the cost-saving potential for manufacturers and lead them to easier fit the global markets. On the other hand, in such networks of factories, coordination is very important for the just-in-time delivery of orders. This study...

There is a lack of research on flexible job shop scheduling problem (FJSP) considering limited fixture-pallet resources in multi-product mixed manufacturing workshop. However, field research in a leading engine manufacturer in China has revealed that fixture-pallet resources are a key factor...

Harmony search algorithm (HS) cannot always avoid being trapped in local optima, and several local search algorithms have recently been used to overcome this limitation by searching the neighborhood of some solution for improved ones. However, how local search affects the performance of HS has...

This study aims to minimize vessels’ waiting time and delay time cost, and constructs an MIP model for integrated QCAP. Considering the uncertainty in QCs efficiency, this study extends the deterministic model to a chance-constrained SP model and DRCC model. Besides, this study introduces CG...

This paper analyses the production planning for the multi mixed-model assembly lines (MMMAL) for building elements prefabrication. Industrialised housebuilding (IHB) prefabrication plants struggle with increasing the productivity of existing prefabrication equipment through the application of...

This study deals with the scheduling problem to minimize makespan at a wet clean station in semiconductor fabrication. The wet clean station is comprised of sequential chemical and rinsing baths for cleaning wafer lots and multiple robot arms for lot handling. In the station, wafer lots are...
