Lot Sizes

We consider the problem of determining realistic and easy-to-schedule lot sizes in a multiproduct, multistage manufacturing environment. We concentrate on a specific type of production, namely, flow shop type production. The model developed consists of two parts, lot sizing problem and scheduling problem. In lot sizing problem, we employ binary integer programming and determine reorder intervals for each product using power-of-two policy. In the second part, using the results obtained of the lot sizing problem, we employ mixed integer programming to determine schedules for a multiproduct, multistage case with multiple machines in each stage. Finally, we provide a numerical example and compare the results with similar methods found in practice.

The reasonable dispatching and scheduling of the Tandem Quay Cranes and trucks is the foundation to improve the efficiency of the container terminals. Under the base of single lift quay cranes research, a research on Tandem Lift Quay Cranes and Yard Trucks scheduling is carried on in this paper. A mixed integer programming (MIP) model can be built to solve an integrated tandem lift quay crane and yard truck scheduling problem (i-TLQCYT). A Local Sequence-cut Method is applied to solve the model. Then the shortest time to complete the unloading operations can be got.
