【摘要】：随着计算机软硬件的不断发展和人们个性化需求的增长，生产加工企业的竞争日益激烈。食品加工企业更注重食品的安全卫生以及成本效益，，除了设备的利用率、员工的操作速度等因素会影响企业成本以外，企业生产加工区的车间布局也会对企业成本产生影响，同时，由于车间布局不合理造成的浪费现象比比皆是。本文采用系统布置设计方法与仿真技术相结合的方法，以食品加工企业为研究对象，分析了YDS食品加工企业生产物流系统的结构以及该企业西点生产加工的工艺流程，根据SLP方法的步骤，对原有布置方案进行优化，重新设计出了若干新的布局方案，并用加权因素法对若干新方案进行比较，选择出较优的一个作为建模仿真的研究对象。再结合专业仿真软件Arena，对该企业的西点产品包装与检测阶段建立模型，进行仿真，分析运行结果，不断通过多次的“设计-仿真-评价-修改”过程得到合理较优的方案。对生产物流系统进行合理有效的优化设计，不仅使得生产物流厂区内部布局规范，车间布置合理，工序能有效衔接，而且提高了该食品加工企业的生产效率，降低生产成本，实现了生产系统流程的快速化和柔性化，对于整个食品加工行业以及其他行业的系统布局设计也具有一定的指导意义。本论文的研究成果主要有以下几点：（1）对几种比较典型的生产物流系统进行了比较，分析了不同类型的生产物流系统在布局上存在的不合理问题，并且对多种系统布置设计的方法进行了简单的优缺点分析，选择了系统布置设计方法与仿真技术相结合的方法。（2）结合企业实际，对收集的产品、产量等系统布置设计基本要素进行了分析，并对该企业西点生产加工区的总体布局进行较系统的研究、设计和评价。（3）阐述了Arena的建模步骤，选取YDS食品加工企业两种西点产品包装与检测阶段来建立Arena仿真模型，并依次介绍了参数设置过程，最后分析了Arena仿真运行报告，利用仿真结果对设计方案进行了验证，表明了所建模型在一定程度上对实际系统的代表性。（4）编制了方案因素检点表，利用比较容易实行的优缺点比较法对原有布置方案和新方案进行比较评价，在一定程度上说明了新方案在设施布置、辅助车间设置、生产安全性等方面的优势，提高了员工的效率，创造了良好的工作环境，减少了浪费。本文的创新点主要有两个方面：第一，本文将系统布置设计方法与专业仿真软件Arena仿真技术结合使用，为企业的生产物流管理和生产物流系统布置设计提供了有效科学的方法和技术。第二，采用简化模型的方法，运用Arena以部分阶段代表整个系统来建立模型，并结合实际，分析运行结果，对新旧方案进行比较。
[Abstract]:With the continuous development of computer software and hardware and the increase of people's individualized demand, the competition of production and processing enterprises is becoming increasingly fierce. Food processing enterprises pay more attention to food safety, hygiene and cost effectiveness. Besides the utilization of equipment and the operating speed of employees, other factors will affect the cost of the enterprise, and the layout of the workshop in the production and processing zone of the enterprise will also have an impact on the cost of the enterprise. At the same time, due to the unreasonable layout of the workshop caused by the waste phenomenon abound. In this paper, the structure of the production logistics system of YDS food processing enterprise and the technological process of production and processing at the west point of the food processing enterprise are analyzed by combining the design method of system layout with the simulation technology and taking the food processing enterprise as the research object. According to the steps of the SLP method, the original layout scheme is optimized, some new layout schemes are redesigned, and some new layout schemes are compared with the weighting factor method, and a better one is selected as the research object of modeling and simulation. Combining with the professional simulation software Arena, the paper establishes the model of the West Point product packaging and testing stage of the enterprise, simulates, analyzes the running results, and obtains a reasonable and better scheme through the process of "Design-Simulation-Evaluation-Modification" several times. The reasonable and effective optimization design of the production logistics system not only makes the layout of the production logistics factory area standard, the workshop layout reasonable, the working procedure can be effectively connected, but also improves the production efficiency and reduces the production cost of the food processing enterprise. It has realized the quickness and flexibility of the production system flow, and has certain guiding significance for the system layout design of the whole food processing industry and other industries. The main research results of this paper are as follows: (1) several typical production logistics systems are compared, and the unreasonable problems in the layout of different production logistics systems are analyzed. The advantages and disadvantages of various system layout design methods are analyzed, and the method of combining system layout design method with simulation technology is selected. (2) combined with the actual situation of the enterprise, this paper analyzes the basic elements of the system layout design of the collected products and the output, and makes a systematic study, design and evaluation on the overall layout of the production and processing zone at the west point of the enterprise. (3) the modeling steps of Arena are expounded, and the Arena simulation model is established by selecting two kinds of western point product packaging and testing stages of YDS food processing enterprises, and the parameter setting process is introduced in turn. Finally, the Arena simulation operation report is analyzed. The simulation results show that the model is representative of the actual system to some extent. (4) compile the check list of scheme factors, compare and evaluate the original layout scheme and the new scheme by using the advantage and disadvantage comparison method which is easy to carry out, and explain to some extent the new scheme in facility layout and auxiliary workshop setting. Production safety and other advantages, improve staff efficiency, create a good working environment, reduce waste. The innovation of this paper mainly has two aspects: first, this paper combines the system layout design method with the professional simulation software Arena simulation technology. It provides an effective and scientific method and technology for production logistics management and layout design of production logistics system. Secondly, using the simplified model method, using Arena to represent the whole system in some stages to build the model, and combining with the practice, analyzing the results of the operation, comparing the new and the old scheme.
