悬臂式掘进机维保成本统计数据集

数据采集以派工单为核心载体，定向采集掘进机维保过程中的物料信息（名称、型号、数量、单价）、成本构成（物料成本、人工费、公摊费用）、设备基础信息（型号、客户、维保班组）、流程信息（过账时间、审核时间）等关键维度，确保数据来源可追溯；数据加工遵循 “清洗规整—分类统计—维度拆解—对比分析” 逻辑，先剔除无效冗余数据、统一数据格式，再按设备型号、物料类型、成本构成等维度进行分类汇总，通过统计核算、占比分析、差异对比等算法，提炼核心成本指标与关键规律。

Data collection takes work orders as the core carrier, and targetedly collects key dimensions including material information (name, model, quantity, unit price), cost composition (material cost, labor cost, shared overhead costs), basic equipment information (model, client, maintenance team), and process information (posting time, audit time) during the maintenance and repair of roadheaders, so as to ensure traceable data sources. Data processing follows the workflow logic of "cleaning and standardization - classification and statistics - dimension decomposition - comparative analysis": first, invalid and redundant data is removed and data formats are standardized; then, classification and summarization are performed based on dimensions such as equipment model, material type and cost composition. Core cost indicators and key regularities are extracted via algorithms such as statistical accounting, proportion analysis and difference comparison.

背景与挑战

背景概述

该数据集聚焦于悬臂式掘进机的维护保养成本统计，由企业自行产生，适用于煤矿设备管理和财务成本管控领域。它通过采集维保过程中的物料、成本和设备信息，支持维保预算编制、采购策略制定以及设备全生命周期成本分析，更新周期为年，数据规模较小（144kb），便于定期分析和优化维保成本。
