谷物类食品配送幼儿园金额数据

通过配送管理系统软件采集本公司谷物类食品配送幼儿园订单信息，将不同的配送订单以各幼儿园来划分，从而计算各个幼儿园每个月的配送金额数据，再计算出每年配送金额的方差大小，方差大小用来评价各个幼儿园的配送情况，从而用于评估所有幼儿园的采购和配送策略，所有配送企业可以通过该数据了解谷物类食品在不同幼儿园的配送行情，以平衡采购和配送谷物类食品数量。对于超平稳型幼儿园，所有配送企业无需时时关注该幼儿园的行情，可每月保持好谷物类食品的采购和配送数量；对于一般平稳型幼儿园，所有配送企业需每季度关注该幼儿园的行情，适当调整谷物类食品的采购和配送数量；而对于波动型幼儿园，所有配送企业需每月时时关注该幼儿园行情，了解该幼儿园的配送行情变化，以适应大幅度调整谷物类食品的采购和配送数量变化。步骤1：通过配送管理系统软件采集本公司谷物类食品配送幼儿园的订单信息，将不同的配送订单以各幼儿园来划分归类，从而将各年度每个月配送至幼儿园的金额，从一月至十二月依次用y1,y2...y12表示，并汇总计算得到各个幼儿园当年的总配送金额y。步骤2：计算各幼儿园的月平均配送金额y̅=各个幼儿园当年的总配送金额y/12。步骤3：根据方差公式计算方差s2={(y1-y̅)^2+(y2-y̅)^2+(y3-y̅)^2+…+(y12-y̅)^2}/12，从而得到各个幼儿园的配送金额的方差s2大小。步骤4：当方差s2小于0.003评价该幼儿园为超平稳型幼儿园。当方差s2大于等于0.003并且小于等于0.008评价该幼儿园为一般平稳型幼儿园。当方差s2大于0.008评价该幼儿园为波动型幼儿园。

First, collect order information of the company's grain food deliveries to kindergartens via the delivery management system software, classify different delivery orders by each kindergarten, calculate the monthly delivery amount data for each kindergarten, then compute the annual variance of the delivery amount. The variance value is used to evaluate the delivery performance of each kindergarten, thereby supporting the assessment of procurement and delivery strategies for all target kindergartens. All delivery enterprises can utilize this dataset to understand the delivery market dynamics of grain food across different kindergartens, so as to balance the procurement and delivery volumes of grain food. For ultra-stable kindergartens, all delivery enterprises do not need to monitor their market conditions at all times, and can maintain consistent procurement and delivery volumes of grain food each month; For generally stable kindergartens, all delivery enterprises need to monitor their market conditions every quarter and make appropriate adjustments to the procurement and delivery volumes of grain food; For fluctuating kindergartens, all delivery enterprises need to closely monitor their market conditions every month to grasp changes in their delivery dynamics, so as to accommodate large-scale adjustments to the procurement and delivery volumes of grain food.

Step 1: Collect order information of the company's grain food deliveries to kindergartens via the delivery management system software, classify different delivery orders by each kindergarten, denote the monthly delivery amounts from January to December of a given year for a target kindergarten as y₁, y₂, …, y₁₂ in sequence, and summarize to obtain the total annual delivery amount y of the kindergarten for that year.
Step 2: Calculate the monthly average delivery amount ȳ = total annual delivery amount y / 12 of the kindergarten.
Step 3: Compute the variance s² using the standard variance formula: s² = [(y₁-ȳ)² + (y₂-ȳ)² + (y₃-ȳ)² + … + (y₁₂-ȳ)²]/12, thereby obtaining the variance s² of the delivery amounts for each kindergarten.
Step 4: Classify the kindergarten as ultra-stable if s² < 0.003; classify it as generally stable if 0.003 ≤ s² ≤ 0.008; classify it as fluctuating if s² > 0.008.
