Abstract
The purpose of this research is to solve the problems of unreasonable layout of the production plant, disorder of the logistics process, and unbalanced production line in discrete manufacturing plants. By analyzing the production process and characteristics, the timed Petri net model is constructed according to the function and connection of each production unit, which is then used to generate a FlexSim simulation model of the production plant logistics system with a simulation software. Therewith the FlexSim simulation model is used to simulate the original layout of the plant, and to analyse the simulation data synthetically to put forward an improvement strategy. Combined with the use of the systematic layout planning method to analyze the overall layout of the plant and logistics relations, we infer the relevant drawings between the production units and determine the improved layout of the facilities. Finally, by comparing the before and after improvement simulation results, it is verified that the combination of timed Petri nets and systematic layout planning is effective to ameliorate the layout of the plant facilities and the logistics system. This method makes up for the factors that traditional methods have not considered, achieves the goal of reducing the cross circuitous route of the plant and the idle rate of equipment, and improving the efficiency of production.
Highlights
With the increasing degree of automation in China’s discrete manufacturing industry, the potential for improving the efficiency of processing procedures to reduce costs has been narrowing
Based on the research in this paper, it can be known that the proposed improvement method can solve the problems of unbalanced equipment utilization, bottleneck, unreasonable plant layout, effectiveness of interaction between simulation model and actual production system etc
This study investigates the status of a large wind power bearing production plant, with collection of relevant information and data and its application to the systematic layout planning (SLP) method to re-plan the layout of plant facilities
Summary
With the increasing degree of automation in China’s discrete manufacturing industry, the potential for improving the efficiency of processing procedures to reduce costs has been narrowing. As the result the key to enterprise competition has gradually shifted to new areas, such as logistics technologies that is closely related to production [1]. As an important part of the improvement of the production logistics system, refers to meeting the necessary constraints in a certain production environment, and determining the reasonable layout form and location of the equipment according to the production goals [2]. The layout planning of plant facility based on the TdPN and SLP
