Abstract: Single-row facility layout is widely used in manufacturing system. It has a very important effect on the performance of manufacturing system. The single-row facility layout, including linear, U-shape, and semi-circular layout are introduced firstly. Based on the lower selling price of customers’ demand, the components of manufacturing cost are analyzed secondly. Then the relationship between the manufacturing cost and objectives of single-row layout are described. Meanwhile, the mathematical and simulation models related to several parts of manufacturing cost of single-row layout are set up respectively. Finally, the simulation of these models for single-row layout is running in QUEST. After analyzing the simulation results, conclusions are obtained: (1) material handling cost of semi-circular layout is the lowest among the three types of single-row facility layout; (2) area utilization rate of U-shape layout is higher than others; (3) equipment and labor utilization of U-shape layout is the higher than others in the same moment. This research results will

Abstract: Float polishing is one of the advanced ultra-smooth surface polishing techniques. Mechanical structure and polishing principle of float polishing are introduced. Polishing experiment about polishing ultra-smooth surface of GCr15 rectangular workpiece is performed by the CJY500 ultra-precision polishing machine, experimental results show that float polishing should be achieved metal nanometer level surface without degenerating layer. The application scope of float polishing is extended, the application has significant reference value for polishing ultra-smooth surface of metal workpiece.

Abstract: Facility layout plays an important role in the performance of manufacturing systems. Firstly, this paper describes the derivations and classification of facility layout problem (FLP). The concepts of static facility layout problem (SFLP), dynamic facility layout problem (DFLP) and robust layout problem are introduced, and their main performance characteristics are compared with each other. Then, the procedure of rearrangement costs in DFLP is proposed. Some main characteristics of SFLP and DFLP, DFLP and robust layout are compared respectively. Lastly, the difference and connection among SFLP, DFLP and robust layout are analyzed. The research results indicate that the dynamic facility layout and robust layout are suitable for the dynamic and changeable manufacturing systems. The method for development of DFLP and its implementation are presented based on SFLP and robust layout.

Abstract: Single-row layout is widely used within GT cells, in facilities that implement JIT, and sometimes with FMS. The three types of single-row layout, including linear, U-shape, and semi-circular layout are introduced firstly. Based on the lower selling price of customers’ demand, the components of manufacturing cost are analyzed secondly. Then the relationship between the manufacturing cost and objectives of single-row layout are described. Meanwhile, the models related to several parts of manufacturing cost of single-row layout are set up respectively. Finally, the simulation of these models for three types of single-row layout is running in QUEST. After analyzing the simulation results, conclusions are obtained: (1) area and labor utilization of linear layout are higher than the others, (2) material handling cost of semi-circular is lowest among these three types of single-row layout, and (3) equipment utilization of them are almost the same. This research results will provide the references in selecting the types of single-row layout based on manufacturing cost.
