汽车钢丝绳需求量预测数据

本数据聚焦于预测汽车钢丝绳产品的需求量，为公司（作为特种钢丝绳生产商）及外部相关方提供了重要的决策依据，具有显著的应用价值。具体体现在以下方面：
1.优化生产计划：通过预测钢丝绳需求量，可以优化捻股机的生产调度，特别是能合理安排不同直径、不同结构钢丝绳的生产顺序，提高设备利用率，降低能耗成本。
2.支持市场决策：为起重机运营单位、电梯维保企业提供科学的更换周期参考，基于预测数据建立预防性维护体系，提前做好钢丝绳更换准备，避免突发断裂事故。1.数据采集：
采集公司汽车钢丝绳产品的销售数据，包括客户编号、订单日期、产品名称、订单数量、订单金额。
2.数据预处理：
对采集的数据进行清洗，去除重复记录，处理缺失值。
3.数据加工与分析：
（1）计算历史需求量：对于汽车钢丝绳产品，使用SUMIFS函数对订单数量进行累加，分别计算出其过去365天、90天和30天的总需求量。（2）建立需求量预测模型：汽车钢丝绳产品的未来30天需求量预测值=[(过去365天总需求量÷365×0.5)+(过去90天的总需求量÷90×0.3)+(过去30天的总需求量÷30×0.2)]×30×1.05；其中，系数0.5、0.3、0.2反映数值对未来30天需求量预测的影响程度，由于算法更注重长期需求趋势的影响，因此365天数据被赋予了最高的权重。1.05是基于市场增长预期给出的修正值。

This dataset focuses on forecasting the demand for automotive steel wire rope products, providing critical decision-making support for the company (as a specialty steel wire rope manufacturer) and external stakeholders, with significant application value, which is reflected in the following aspects:
1. Optimize production planning: By forecasting the demand for steel wire ropes, the production scheduling of stranding machines can be optimized, especially the production sequence of steel wire ropes with different diameters and structures can be reasonably arranged, thereby improving equipment utilization and reducing energy consumption costs.
2. Support market decision-making: Provide scientific replacement cycle references for crane operation enterprises and elevator maintenance enterprises, establish a preventive maintenance system based on forecast data, prepare for wire rope replacement in advance, and avoid sudden breakage accidents.
1. Data collection:
Collect sales data of the company's automotive steel wire rope products, including customer ID, order date, product name, order quantity, and order amount.
2. Data preprocessing:
Clean the collected data, remove duplicate records, and handle missing values.
3. Data processing and analysis:
(1) Calculate historical demand: For automotive steel wire rope products, use the SUMIFS function to accumulate order quantities, and calculate the total demand over the past 365 days, 90 days, and 30 days respectively.
(2) Establish demand forecasting model: The 30-day future demand forecast value of automotive steel wire rope products is calculated as: (Total demand over the past 365 days / 365 × 0.5) + (Total demand over the past 90 days / 90 × 0.3) + (Total demand over the past 30 days / 30 × 0.2) × 30 × 1.05; Among them, the coefficients 0.5, 0.3, and 0.2 reflect the impact of the corresponding historical data on the 30-day future demand forecast. Since the algorithm places more emphasis on the impact of long-term demand trends, the 365-day data is assigned the highest weight. The value of 1.05 is a correction factor based on market growth expectations.
