【摘要】：隨著我國經濟的快速發(fā)展,汽車保有量也急速增加,隨之而來的是汽車配件需求呈井噴式增長,從而給汽車配件物流行業(yè)也帶來了新的機遇和挑戰(zhàn)。汽車配件裝車是汽車配件物流的重要環(huán)節(jié),但是在我國卻沒有得到足夠的重視,存在著信息化程度不高、標準化流程缺失、過多依靠個人經驗等問題。這不但使得配件物流裝車及時率、運輸及時率等指標過低,造成了時間上的浪費,而且容易使配件在運輸過程中損耗率過高、物流成本居高不下,從而導致配件物流服務效率低下。本文的目標是開發(fā)汽車配件物流裝車系統,并集成于現有JL汽車配件物流協同監(jiān)控系統中,要求該裝車系統可以給物流科人員提供個性化裝車方案,并使裝車環(huán)節(jié)信息化,提高各業(yè)務單位直接的協同效率。本文的主要內容有：1.先對目前我國配件物流在裝車環(huán)節(jié)現狀進行分析,然后針對現有JL配件物流協同監(jiān)控系統在裝車環(huán)節(jié)上與實際業(yè)務流程不夠切合的問題進行研究,得出存在的不足和其中的可提升之處,然后對裝車系統進行了需求分析,最后介紹了解決方案。2.對核心模塊個性化裝車功能中的綜合裝車、嚴格按距離裝車、同類塊裝車和塞貨功能提供算法支持,設計了基于同類塊裝載的啟發(fā)式算法和基于精英策略的混合蟻群算法。3.對裝車算法以構件形式進行封裝以提高代碼可移植性和重復利用率,并使用基于WebGL的Three.js三維繪畫引擎,實現在無插件情況下以Web模式裝車計劃三維效果展示。4.對系統的總體解決方案進行設計實現,并以業(yè)務流程的角度對裝車系統的系統功能進行驗證。
[Abstract]:With the rapid development of our country's economy, the quantity of automobile has been increasing rapidly, and the demand of auto parts has been increasing rapidly, which brings new opportunities and challenges to the logistics industry of auto parts. Automobile parts loading is an important part of automobile parts logistics, but it has not been paid enough attention to in our country. There are some problems such as low level of information, lack of standardization process, excessive reliance on personal experience and so on. This not only makes spare parts logistics loading timely rate, transportation timely rate and other indicators are too low, resulting in a waste of time, but also easy to make the spare parts in the process of transportation loss rate is too high, logistics costs remain high. As a result, accessories logistics service efficiency is low. The aim of this paper is to develop the automobile parts logistics loading system and integrate it into the existing JL auto parts logistics cooperative monitoring system. It is required that the loading system can provide the personalization loading scheme for the logistics department personnel and make the loading link information. Improve the direct synergy efficiency of each business unit. The main content of this paper is: 1. First of all, this paper analyzes the present situation of spare parts logistics loading in our country, and then studies the problem that the existing JL spare parts logistics collaborative monitoring system is not suitable for the actual business process in the loading link. The shortcomings and elevating points are obtained, and then the requirement analysis of the loading system is carried out. Finally, the solution. 2. 2. For the integrated loading of the core module in the individualized loading function, strictly according to the distance loading, the similar block loading and stopper function are provided with algorithm support. The heuristic algorithm based on the similar block loading and the hybrid ant colony algorithm. 3 based on the elite strategy are designed. The loading algorithm is encapsulated in the form of component to improve the portability and reuse of code, and the 3D drawing engine of Three.js based on WebGL is used to display 3D effect of loading plan in Web mode without plug-in. The overall solution of the system is designed and implemented, and the system function of the loading system is verified from the point of view of business process.
