【摘要】：隨著市場(chǎng)需求多樣化、個(gè)性化的轉(zhuǎn)變，多品種、小批量生產(chǎn)模式已成為離散制造企業(yè)的主要生產(chǎn)模式，帶來(lái)的問(wèn)題是車間生產(chǎn)物料類型急劇增加，為保障正常生產(chǎn)，準(zhǔn)時(shí)、精確的物料配送顯得尤為重要。 以某汽車企業(yè)混流裝配車間為研究對(duì)象，以精準(zhǔn)化配送為指導(dǎo)思想，以物聯(lián)網(wǎng)核心技術(shù)為支撐，研究企業(yè)生產(chǎn)過(guò)程中物料配送調(diào)度模型。在生產(chǎn)現(xiàn)場(chǎng)實(shí)時(shí)信息反饋的基礎(chǔ)上，從配送作業(yè)的流程分析、模型建立、求解方法等方面探討如何合理安排物料配送作業(yè)計(jì)劃，實(shí)現(xiàn)對(duì)生產(chǎn)線物料動(dòng)態(tài)需求的響應(yīng)。 通過(guò)分析混流裝配車間物料配送特點(diǎn)，研究了物料配送與監(jiān)控關(guān)鍵技術(shù)，針對(duì)生產(chǎn)現(xiàn)場(chǎng)的物料配送與監(jiān)控、裝配防錯(cuò)等需求，提出物料配送與跟蹤的總體框架。針對(duì)混流裝配車間物料分類機(jī)制和配送方式，以混流裝配車間精確布局和工位物料準(zhǔn)確需求已知為前提，建立了物料配送路徑優(yōu)化模型，采用智能算法對(duì)模型進(jìn)行求解，實(shí)現(xiàn)物料配送車輛路徑優(yōu)化。針對(duì)車間物料管理可視化的需求，分別設(shè)計(jì)基于RFID的物料識(shí)別系統(tǒng)和基于ZigBee的物料監(jiān)控網(wǎng)絡(luò)，，并采用RFID和ZigBee結(jié)合的方式實(shí)現(xiàn)智能物料匹配檢測(cè)。在上述研究成果基礎(chǔ)上，設(shè)計(jì)了物料配送與監(jiān)控系統(tǒng)，實(shí)現(xiàn)了物料配送作業(yè)全過(guò)程監(jiān)控，該系統(tǒng)已經(jīng)在江淮汽車公司正式上線使用1年時(shí)間。
[Abstract]:With the diversification of market demand and the change of individuation, multi-variety and small-batch production mode has become the main production mode of discrete manufacturing enterprises. The problem is that the type of materials produced in workshop increases sharply, in order to ensure normal production, punctual production, Accurate material distribution is particularly important. Taking the mixed-flow assembly workshop of an automobile enterprise as the research object, taking the precision distribution as the guiding ideology and the core technology of the Internet of things as the support, this paper studies the material distribution scheduling model in the production process of the enterprise. On the basis of real-time information feedback on production site, this paper discusses how to arrange the operation plan of material distribution reasonably from the aspects of flow analysis, model establishment and solution method of distribution operation, so as to realize the response to the dynamic demand of material in production line. By analyzing the characteristics of material distribution in mixed-flow assembly workshop, the key technologies of material distribution and monitoring are studied. The overall framework of material distribution and tracking is put forward to meet the requirements of material distribution and monitoring in production site, assembly error prevention and so on. Aiming at the material classification mechanism and distribution mode of mixed flow assembly workshop, a material distribution path optimization model is established on the premise of accurate layout of mixed flow assembly workshop and accurate material requirement of work station. Intelligent algorithm is used to solve the model. The vehicle route optimization of material distribution is realized. According to the requirement of material management visualization in workshop, the material identification system based on RFID and the material monitoring network based on ZigBee are designed, and the intelligent material matching detection is realized by the combination of RFID and ZigBee. Based on the above research results, a material distribution and monitoring system is designed, which realizes the whole process monitoring of material distribution. The system has been used in Jianghuai Automobile Company for one year.
