Research On Application Mode And Method Of Simulation In Distribution Center Design

According to extensive industry practice and research literature, simulation application is restricted to late stage of the design course as a post-event verification tool. Consequently, its function as a design flaw detector and a design inspiration supplier are limited, and input data reliability as well as modeling systematicness are compromised. This paper focuses on reforming traditional application mode of simulation in distribution center design. An application framework aimed at earlier, wider, positive and systematic involvement of simulation in distribution center design is proposed. Simulation application mode and method are discussed in three aspects including simulation full participation, simulation-oriented design and simulation systematic participation.As for full participation of simulation, distribution center design steps and procedure are investigated through literature review and project experience. Design phases and operation modules are studied. Simulation proposal and cases on design steps, phases and modules are given as examples.As for simulation-oriented design, procedures led by simulation are developed to solve the problems in traditional application of simulation in distribution center design. Simulation analysis method based on design flow chart is explored and illustrated.As for simulation systematic participation, a combination of simulation full participation and simulation-oriented design is highlighted. Reusability and fidelity management of simulation model are considered for simulation cost control.Integrating the three aspects above, simulation application framework in distribution center design is developed. A mechanic distribution center is employed at last for application introduction.Aimed at solving common problems in traditional mode, this paper presents a set of application methodologies of simulation in distribution center design which is illustrated through specific industrial cases. Under the guidance of this framework, functions of simulation in design flaw detection and design inspiration can be fully used; simulation data reliability and simulation cost management can be effectively improved.
