This paper studies the optimization problem of PCB assembly time for multi-head placement machine. Mathematical model is built and analyzed for the problem, which is of a combinatorial nature and computationally intractable. An optimization algorithm based on heuristic strategy and scatter search method is proposed to minimize the PCB assembly time. By relaxing the restrictions on the problem, the...
The operation optimization problem considered in this paper arises on a multi-head surface mounting machine with over-head gantry when it mounts electronic components on the surface of a printed circuit board (PCB) in PCB assembly. The aim of the problem is to minimize the time that a machine takes to mount all the required components. It is a complex optimization problem involving three inner-related...
This paper considers the SMT placement process optimization problem to minimize the assembly time of Multi-head surface mounting machine (SMM).A mathematical model is firstly established.Considering that the component pick-and-place sequencing and the feeder assignment are the two main important factors which determine the assembly time of a device,the optimization problem is divided into two sub-problems,called...
In this paper, we focus on printed circuit boards (PCB) and their components arrangement optimization problem, which is derived from electronic surface mounting manufacturing process. It includes two tasks: the sequencing of PCBs and the assignment of components on PCBs to different mounting machines. A taboo search (TS) with kick strategy is proposed to solve this problem: (1) ordinal optimization...
