This research deals with multiple Gantry-type assembly machines for the optimization of PCB assembly line. The automated assembly machine has 6 nozzles which can linearly move the X axis and the Y axis different from the turret type assembly machine. Each

  This paper improves algorithms for an assembly-type flowshop scheduling problem in which each job is to assemble two types of components and makespan is the objective measure. For the assembly, one type of the components is outsourced with job-dependent

  This paper considers an assembly-type flowshop scheduling problem in which each job is assembled with two types of components. One type of the components is outsourced with positive lead time but the other type is fabricated in-house at the first stage.

This paper considers a scheduling problem concerned with an assembly system where two components are first treated in their own parallel machines and then pulled to be assembled into a final product at a single assembly machine. The objective measure is t

The purpose of this paper is to solve the problem that is occuring in assembly process and to progress the productivity by process analysis methods for manu-open and closed model(DWV-20/25DRG), and auto-open and cloesd model(DWV-20/25/DRA)-ventilation fan. Also, this paper is studied by data of ＇D＇ company's product.
