大型超市“購物藍”問題
作為超市的經理，經常關心的問題是顧客的購物習慣。他們想知道：“什么商品組合或集合，顧客多半會在一次購物時同時購買？”。現在假設你是超市的市場分析員，已經掌握了該超市近一個星期的所有顧客購買物品的清單和相應商品的價格，需要你給超市經理一個合理的“購物藍”分析報告，并提供一個促銷計劃的初步方案。
具體的說，需要完成如下任務：
1、附件1中的表格數據顯示了該超市在一個星期內的1024個顧客對999種商品的購買記錄，表格中每一行代表一個顧客的購買記錄，數字代表了其購買商品的超市內部編號。試建立一種數學模型，該模型能定量表達超市中多種商品間的關聯關系的密切程度。
2、根據你在問題1中建立的模型，尋找一種快速有效的方法能從附件1中的購買記錄中分析出那些商品是最頻繁被同時購買的。超市經理希望得到盡可能多的商品被頻繁同時購買的信息，所以你找到的最頻繁被同時購買的商品數量越多越好。
例如：如果商品1、商品2、商品3在1024個購物記錄中同時出現了200次，則可以認為這三個商品同時頻繁出現了200次，商品數量是3。
3、附件2給出了這999種商品對應的利潤，試根據前面建立的模型，給出一種初步的促銷方案，使超市的效益進一步增大。
4、給超市經理寫一個報告，分析超市的現狀并對將來超市購物藍信息的收集策略提出建議。
