基于计算机显示器历史销量预测下月销量数据
收藏资源简介：
通过计算机显示器下月销量的预测，可以帮助企业提前合理预测销量，库存应该备货多少，若库存不足，则发出预警信号，方便制定生产计划。可以有效地提高生产效率和降低成本，确保按时交货和提升客户满意度，帮助同行业企业优化资源配置和生产能力，能更好地应对市场变化和客户需求，并且对于供货商，也能有针对性的进行生产产品以保证货源稳定供应。1.数据采集：采集本公司计算机显示器前三个月的销售和订单信息以及后台库存信息。2.数据处理：对采集到的原始数据进行处理，去除缺失和异常数据。 3.数据分析：采用加权移动平均法预测销量，预测下月销量S=（S1*k1+S2*k2+S3*k3）/（k1+k2+k3），S取整数值，其中S1：上一个月的销量，S2：上上一个月的销量，S3：上上上一个月的销量，例如S1为5月销量，S2为4月销量，S3为3月销量，则S为7月销量。k1、k2、k3为权重系数，根据计算得出分别为3.6、2.4、1.2。库存健康监测P=实际库存/预测下月销量，库存健康阈值Q1=1.4，Q2=1.8，库存预警=IFS（P＜Q1为“库存不足”，Q1≤P≤Q2为“库存正常”，P>Q2为“库存积压”）。4.数据应用：通过销量的预测，可以帮助企业提前合理预测销量，库存应该备货多少，若库存不足，则发出预警信号，需要及时考虑补货，若库存积压，则需要推出活动及时清理库存。
Forecasting the monthly sales volume of computer monitors can help enterprises reasonably predict sales in advance, determine the appropriate inventory stock level, issue early warning signals when inventory is insufficient, facilitate production planning, effectively improve production efficiency and reduce costs, ensure on-time delivery and enhance customer satisfaction, assist enterprises in the same industry to optimize resource allocation and production capacity, better respond to market changes and customer demands, and enable suppliers to conduct targeted production to ensure stable supply of goods. 1. Data Collection: Collect the sales, order information and background inventory data of the company's computer monitors over the past three months. 2. Data Processing: Process the collected raw data by eliminating missing and abnormal data entries. 3. Data Analysis: Adopt the weighted moving average method to forecast sales volume. The formula for forecasting the next month's sales S is: S=(S1*k1 + S2*k2 + S3*k3)/(k1 + k2 + k3), where S is rounded to an integer. Specifically, S1 denotes the sales volume of the previous month, S2 the sales volume of the month before last, and S3 the sales volume of two months prior. For example, if S1 represents the sales volume in May, S2 in April, and S3 in March, then S is the forecasted sales volume for July. The weight coefficients k1, k2, and k3 are calculated as 3.6, 2.4, and 1.2 respectively. The inventory health index P is calculated as P = actual inventory / forecasted next month's sales volume. The inventory health thresholds are set as Q1=1.4 and Q2=1.8. The inventory early warning rule is defined via the IFS function: "insufficient inventory" when P < Q1, "normal inventory" when Q1 ≤ P ≤ Q2, and "overstocked inventory" when P > Q2. 4. Data Application: Based on sales forecasting, enterprises can reasonably predict sales in advance and determine the appropriate inventory stock level. Early warning signals will be issued when inventory is insufficient, prompting timely inventory replenishment; when inventory is overstocked, promotional activities should be launched to clear inventory in a timely manner.
