【摘要】：以訂單式生產(chǎn)為主的離散型制造企業(yè),大多采取多品種、小批量混合加工的生產(chǎn)模式,來達到消費者對產(chǎn)品更加個性化、多樣化的要求。在面向訂單式制造企業(yè)的產(chǎn)品生產(chǎn)過程中,由于,車間物料種類繁多,數(shù)量不一,加工時間不固定等問題,因此,設(shè)計一套完整的車間物料準時配送實施方案以及智能化物料準時配送系統(tǒng)來保證此生產(chǎn)模式順利運行。傳統(tǒng)的拉動式配送、周期性配送均屬于被動式配送,經(jīng)常會出現(xiàn)配送不及時、不精確、不合理的現(xiàn)象,從而導(dǎo)致線邊庫存出現(xiàn)缺料或者積壓現(xiàn)象�，F(xiàn)有的準時制物料配送缺乏對現(xiàn)場實時工況的處理,沒有一套完整的行之有效的實施方案。針對以上研究現(xiàn)狀,本論文主要對以下部分做出研究：(1)物料準時配送系統(tǒng)中關(guān)鍵技術(shù)與方法研究。為了解決物料準時配送中的實時物料數(shù)據(jù)信息采集與最優(yōu)配送時間窗口以及最佳配送數(shù)量的確實。本文先從車間物料準時配送中的幾個關(guān)鍵性問題入手進行研究：配送時間點、數(shù)量、次數(shù)。運用改進時間懲罰函數(shù)公式與分析圖相結(jié)合的方法求出最優(yōu)配送時間點、最佳配送數(shù)量。同時,根據(jù)“一車多位”的思想規(guī)劃最少的配送車次,利用高德地圖的工作原理規(guī)劃最優(yōu)路徑,接著,基于RFID的實時數(shù)據(jù)采集技術(shù)與電子看板的實數(shù)數(shù)據(jù)監(jiān)控、追溯功能,避免因物料配送信息傳遞的滯后性,而出現(xiàn)物料配送的不及時、不準確、不合理現(xiàn)象。(2)多目標車間物料準時配送模型研究。實際生產(chǎn)過程中經(jīng)常會出現(xiàn)影響物料準時配送的一些動態(tài)影響因素問題,例如：實時工況變化,緊急插單、變更,工位調(diào)整等。這種動態(tài)影響因素會帶來配送成本、配送周期、配送車次等的變化,故本文設(shè)定以最短配送時間、最少配送次數(shù)和最低配送成本為多目標,建立物料準時配送多目標數(shù)學模型,并用改進混合PSO來優(yōu)化此配送模型。進而以某造紙機械公司生產(chǎn)的二壓導(dǎo)軌裝置為實際案例,進行實例分析,并用MATLAB仿真軟件對該模型進行驗證分析。(3)設(shè)計一種車間物料準時配送系統(tǒng)實施方案。為了解決在準時制生產(chǎn)模式下,缺乏在物料配送信息管理的思想下建立一套行之有效的整體實施方案問題。本文特意結(jié)合物料準時配送中的一些關(guān)鍵技術(shù)與方法,以及物料準時配送模型,設(shè)計一套完整的車間物料準時配送系統(tǒng)實施方案,并以二維、三維流程圖的形式更加形象的描述其運行過程。同時,針對設(shè)計的車間物料準時配送系統(tǒng)實施方案,運用UML.VS2005和SQL2008等建模工具構(gòu)建原型系統(tǒng),驗證設(shè)計方案的正確性與可行性。
[Abstract]:To order the production of discrete manufacturing enterprises, mostly adopt multi varieties, small batch mixed production mode, to consumers more personalized products, diversified requirements. In order for the manufacturing enterprises in the production process, the workshop, the material variety, quantity, processing time is not fixed such problems, therefore, the design of a complete set of workshop material delivery plan and intelligent material delivery system to ensure the smooth running of pull production mode. The traditional distribution, periodical distribution and distribution are passive, often is not timely delivery, not accurate, unreasonable phenomenon, resulting in line inventory shortage or backlog. The JIT material distribution of lack of real-time status, not a complete set of effective implementation scheme for the above. The research status, this paper made a research on the following parts: (1) research on the key technology and method of material delivery system. In order to solve the problem of material delivery in real-time material data information collection and optimal delivery time window and do the best distribution quantity. This paper starts from the first workshop material delivery in several key issues study: delivery time, number of times. By using the method of improved time penalty function formula and analysis chart combining the optimal delivery time, the best delivery quantity. At the same time, according to "a car" the idea of minimum distribution planning trips, the use of high moral map of the working principle of the optimal path planning, then RFID, real data monitoring, real-time data acquisition technology and electronic Kanban based on tracing function, avoid the lag of transfer material distribution information, and the material distribution Delivery is not timely, accurate, unreasonable phenomenon. (2) research on time distribution model of multi-objective shop material. Influence of material delivery of some dynamic factors, often in the actual production process such as: real time working condition, emergency inserting, change position adjustment. The dynamic impact factors will bring the cost of delivery, delivery cycle, change the distribution of trips, so this paper set the shortest delivery time, delivery times and at least the minimum distribution cost for multi target, set up the material delivery multi-objective mathematical model, and use PSO to optimize the distribution of the improved hybrid model. Two pressure guide and production to a papermaking machinery company as the actual case, case analysis, and the model was verified by the MATLAB simulation software. (3) the implementation of a design workshop material delivery system. In order to solve the JIT production system The lack of mode, establish a set of effective overall implementation of the programme in material distribution information management ideas. This paper specially according to the material delivery of some of the key technologies and methods, as well as the material delivery model, scheme design of a complete set of workshop material delivery system, and the flow chart of 2D, 3D the more the image describe the operation process. At the same time, the implementation scheme for the design of the workshop material delivery system, a prototype system is constructed by using UML.VS2005 and SQL2008 modeling tool, the correctness and feasibility of the design are verified.
