【摘要】：隨著企業(yè)信息化的推進與發(fā)展,銷售數(shù)據(jù)急聚增加,由于銷售數(shù)據(jù)在企業(yè)決策中的重要作用,挖掘銷售數(shù)據(jù)中的有用信息是亟待公司解決的問題。研究出能夠在大數(shù)據(jù)環(huán)境下挖掘銷售數(shù)據(jù)有效信息的數(shù)據(jù)處理方法,正確地使用海量數(shù)據(jù)中挖掘出來的有效信息也是企業(yè)的迫切需求。本文利用海量銷售數(shù)據(jù)中包含的銷售數(shù)據(jù)走勢預(yù)測未來銷售數(shù)據(jù)的趨勢,感知市場狀況,掌握市場動向,給企業(yè)銷售決策者提供有效的銷售數(shù)據(jù)動向參考信息,為生產(chǎn)、營銷,以及判斷市場狀況提供決策依據(jù)。圍繞以上問題,本文對于大數(shù)據(jù)環(huán)境下的企業(yè)銷售數(shù)據(jù)挖掘算法和企業(yè)市場的預(yù)測模型做了一下主要研究:(1)運用Hadoop平臺存儲大數(shù)據(jù),并且運用Hadoop的MapReduce抽取需要處理的數(shù)據(jù),并導(dǎo)入到關(guān)系型數(shù)據(jù)庫中,根據(jù)數(shù)據(jù)挖掘算法中對數(shù)據(jù)結(jié)構(gòu)的需求,針對數(shù)據(jù)中的不同的數(shù)據(jù)異常對數(shù)據(jù)使用不同的清洗策略進行清洗與數(shù)據(jù)規(guī)范,再將處理后的數(shù)據(jù)交付給關(guān)系型數(shù)據(jù)庫。(2)針對傳統(tǒng)的大數(shù)據(jù)挖掘算法存在的問題,本文提出了基于分塊后重疊k-means聚類的KNN分類算法,算法通過給傳統(tǒng)KNN算法增加一個訓(xùn)練過程的方式讓KNN算法能夠運用于大數(shù)據(jù)環(huán)境,并且能夠快速準確地對數(shù)據(jù)進行分類,大大提升了分類算法的效率。并且通過新算法,對零售戶數(shù)據(jù)中的幾個規(guī)格卷煙的銷售詳情進行分類,統(tǒng)計其分類結(jié)果,與實際的數(shù)據(jù)進行了對比,驗證了算法的可行性與準確性。(3)分析各類預(yù)測模型對于本文的研究內(nèi)容的適用性,根據(jù)本文的數(shù)據(jù)特點以及預(yù)期的預(yù)測結(jié)果數(shù)據(jù)特點選擇了適合的預(yù)測模型:差分自回歸滑動平均模型(ARIMA(p,d,q))與灰色模型,作為本文的市場感知模型的基礎(chǔ)。(4)以企業(yè)的零售數(shù)據(jù)為實驗數(shù)據(jù),建立結(jié)合ARIMA差分自回歸滑動平均模型與灰色模型的市場感知模型。根據(jù)ARIMA自回歸移動平均模型能夠準確地預(yù)測未來短期的銷售數(shù)據(jù),但是,由于隨著預(yù)測時間越長預(yù)測的準確率越低的特點,在ARIMA模型的基礎(chǔ)上使用灰色拓撲模型進行長期的銷售數(shù)據(jù)預(yù)測,讓企業(yè)能夠看到的不僅僅是未來半年或者一年內(nèi)的銷售數(shù)據(jù)的預(yù)測,而且能給企業(yè)提供更加準確掌握未來市場動向的數(shù)據(jù)。
[Abstract]:With the promotion and development of enterprise information, sales data is increasing rapidly, because of the important role of sales data in enterprise decision-making. Mining useful information in sales data is an urgent problem to be solved by the company. A data processing method which can mine effective information of sales data in big data environment is developed. It is also an urgent need for enterprises to use the valid information extracted from mass data correctly. This paper uses the trend of sales data contained in mass sales data to predict the trend of future sales data and to perceive the market situation. To grasp the market trends, to provide effective sales data to the decision-makers of the enterprise sales trends reference information, for production, marketing, and to judge the market situation decision-making basis. Around the above issues. In this paper, the enterprise sales data mining algorithm and the enterprise market prediction model under the big data environment are mainly studied. (1) the Hadoop platform is used to store big data. And use the MapReduce of Hadoop to extract the data to be processed, and import into the relational database, according to the data mining algorithm of the data structure requirements. According to the different data anomalies in the data, different cleaning strategies are used to clean and standardize the data. Then the processed data is delivered to the relational database. 2) aiming at the problems of the traditional big data mining algorithm, this paper proposes a KNN classification algorithm based on overlapping k-means clustering. By adding a training process to the traditional KNN algorithm, the algorithm enables the KNN algorithm to be applied to big data environment, and can quickly and accurately classify the data. Greatly improve the efficiency of the classification algorithm. And through the new algorithm, the retail data of several specifications of cigarette sales details classification, statistics of the classification results, and compared with the actual data. The feasibility and accuracy of the algorithm are verified. According to the characteristics of the data in this paper and the characteristics of the predicted results, a suitable prediction model, namely, the differential autoregressive moving average model (ARIMAPA) and the grey model, is selected. As the basis of the market perception model of this paper, we take the retail data of enterprises as the experimental data. A market perception model combining ARIMA differential autoregressive moving average model and grey model is established. According to the ARIMA autoregressive moving average model, the future short-term sales data can be accurately predicted, but. Because the prediction accuracy is lower with the longer the forecast time, the grey topology model is used to predict the long-term sales data on the basis of ARIMA model. What allows the enterprise to see is not only the forecast of the sales data in the next six months or a year, but also provides the enterprise with the data which can grasp the future market movement more accurately.
