Real‐time dynamic hoist scheduling for multistage material handling process under uncertainties

Abstract: in Wiley Online Library (wileyonlinelibrary.com).Multistage material handling processes are broadly used for manufacturing various products/jobs, where hoists are commonly used to transport inline products according to their processing recipes. When multiple types of jobs with different recipes are simultaneously and continuously handled in a production line, the hoist movement scheduling should be thoroughly investigated to ensure the operational feasibility of every job inline and in the meantime to maximize… Show more

“…Zhao et al have recently developed an interesting mixed‐integer linear programming (MILP) model for real‐time hoist rescheduling in a multistage electroplating line. The system consists of a number of processing units and a single material handling hoist.…”

“…When one or multiple jobs arrive, an optimal hoist reschedule should be determined based on the current state of the jobs inline and the hoist. The objective is to minimize the time span required for processing all the jobs inline while satisfying the following three types of constraints: Hoist movement constraints. The release time for the hoist to drop any job in any unit and its corresponding lift time upon completion of processing are well defined so that the hoist is not required to handle more than one job at any time. Unit processing capacity constraints.…”
