+
+## 一、设计理念
+
+### 1.1 目标
+老板想看的不是原始数据的堆砌，而是**一眼能抓住的数据洞察**。因此本报表模块的核心原则：
+
+| 原则 | 说明 |
+|------|------|
+| **KPI 优先** | 每个页面顶部展示关键指标卡片（总计/环比/趋势），让老板一眼看到业务状况 |
+| **图文并茂** | ECharts 图表为主，表格为辅，避免纯表格枯燥 |
+| **层层下钻** | 从汇总趋势 → 点击进入明细 → 再进详情，支持交互式探索 |
+| **聚焦决策** | 报表要能回答老板的问题：花了多少钱？省了多少钱？哪家供应商最好？ |
+
+### 1.2 技术选型理由
+
+| 技术 | 为什么选 |
+|------|---------|
+| **ECharts 5.4.0** | 项目已有依赖（`package.json` 中 `echarts: 5.4.0`），无需额外安装 |
+| **Vue 2 + Element UI** | 项目现有技术栈，风格统一 |
+| **MyBatis 手写 SQL** | 报表查询需要多表聚合，手写 SQL 最灵活 |
+| **RuoYi BaseController** | 延续 `startPage()` + `getDataTable()` 分页模式，与现有代码一致 |
+
+---
+
+## 二、报表总览
+
+### 2.1 报表菜单结构
+
+在**智慧报价**菜单下新增一个分组 **统计分析**，包含 4 个子页面：
+
+```
+智慧报价 (menu_id=2000)
+├── 物料管理          (2001)
+├── 供应商管理        (2002)
+├── 报价请求          (2003)
+├── 供应商报价        (2004)
+├── 智慧比价          (2005)
+├── 采购单            (2006)
+├── 供应商评价        (2007)
+├── 订单异议          (2008)
+├── 交易记录          (2009)
+├── 租户管理          (2010)
+├── ═══════════════════════════════
+├── 📊 统计分析        (2011)  ← 新增目录菜单（父节点）
+│   ├── 📈 采购总览看板   (2012)  ← 仪表盘首页
+│   ├── 💰 采购成本分析   (2013)  ← 成本趋势与对比
+│   └── 🏆 供应商绩效     (2014)  ← 供应商评分与排名
+```
+
+### 2.2 四个报表页面说明
+
+| 页面 | 路由 path | 定位 | 老板能回答什么问题 |
+|------|-----------|------|-------------------|
+| **采购总览看板** | `/bid/report/dashboard` | 仪表盘首页，一屏总览 | 本月花了多少钱？采购趋势怎么样？报价情况如何？ |
+| **采购成本分析** | `/bid/report/cost` | 成本深度分析 | 比预算省了多少？各品类花了多少？同物料价格对比？ |
+| **供应商绩效** | `/bid/report/supplier` | 供应商评分与排名 | 哪家供应商最好？哪家经常出问题？交期/质量/服务排名？ |
+
+---
+
+## 三、页面架构与路由设计
+
+### 3.1 前端路由注册
+
+在 `ruoyi-ui/src/router/index.js` 的 `dynamicRoutes` 中添加：
+
+```js
+// ── 统计分析 路由 ──
+{
+  path: '/bid/report/dashboard',
+  component: Layout,
+  hidden: true,
+  permissions: ['bid:report:dashboard'],
+  children: [{
+    path: '',
+    component: () => import('@/views/bid/report/dashboard'),
+    name: 'ReportDashboard',
+    meta: { title: '采购总览看板', activeMenu: '/bid/report' }
+  }]
+},
+{
+  path: '/bid/report/cost',
+  component: Layout,
+  hidden: true,
+  permissions: ['bid:report:cost'],
+  children: [{
+    path: '',
+    component: () => import('@/views/bid/report/cost'),
+    name: 'ReportCost',
+    meta: { title: '采购成本分析', activeMenu: '/bid/report' }
+  }]
+},
+{
+  path: '/bid/report/supplier',
+  component: Layout,
+  hidden: true,
+  permissions: ['bid:report:supplier'],
+  children: [{
+    path: '',
+    component: () => import('@/views/bid/report/supplier'),
+    name: 'ReportSupplier',
+    meta: { title: '供应商绩效', activeMenu: '/bid/report' }
+  }]
+}
+```
+
+### 3.2 菜单 SQL
+
+在 `bid_tables.sql` 或系统菜单表中执行以下 SQL（先查询最大 menu_id 再插入）：
+
+```sql
+-- 父菜单：统计分析 (2011)
+INSERT IGNORE INTO sys_menu(menu_id, menu_name, parent_id, order_num, path, component, is_frame, is_cache, menu_type, visible, status, perms, icon, create_by, create_time)
+VALUES(2011, '统计分析', 2000, 11, 'report', NULL, 1, 0, 'M', '0', '0', 'bid:report:list', 'chart', 'admin', NOW());
+
+-- 子菜单：采购总览看板 (2012)
+INSERT IGNORE INTO sys_menu(menu_id, menu_name, parent_id, order_num, path, component, is_frame, is_cache, menu_type, visible, status, perms, icon, create_by, create_time)
+VALUES(2012, '采购总览看板', 2011, 1, 'dashboard', 'bid/report/dashboard', 1, 0, 'C', '0', '0', 'bid:report:dashboard', 'dashboard', 'admin', NOW());
+
+-- 子菜单：采购成本分析 (2013)
+INSERT IGNORE INTO sys_menu(menu_id, menu_name, parent_id, order_num, path, component, is_frame, is_cache, menu_type, visible, status, perms, icon, create_by, create_time)
+VALUES(2013, '采购成本分析', 2011, 2, 'cost', 'bid/report/cost', 1, 0, 'C', '0', '0', 'bid:report:cost', 'money', 'admin', NOW());
+
+-- 子菜单：供应商绩效 (2014)
+INSERT IGNORE INTO sys_menu(menu_id, menu_name, parent_id, order_num, path, component, is_frame, is_cache, menu_type, visible, status, perms, icon, create_by, create_time)
+VALUES(2014, '供应商绩效', 2011, 3, 'supplier', 'bid/report/supplier', 1, 0, 'C', '0', '0', 'bid:report:supplier', 'star', 'admin', NOW());
+```

+
+**核心逻辑：**
+
+1. 查询所有 completed 的 RFQ，关联 RFQ Item 中的 `expected_price` 作为预算价
+2. 查询对应被采纳的报价（`quotation.status = 'accepted'`）作为实际采购价
+3. `节省额 = 预算总额 - 实际采购总额`
+4. 表格中每行是一个 RFQ，点击"详情"跳转到比价详情页

+
+**核心交互：**
+
+1. 评分排名表格 - 可点击表头排序

+4. 异议统计 - 展示各供应商的订单问题情况

+
+## 六、数据库查询方案（SQL 核心）
+
+### 6.1 关键业务指标 SQL
+
+#### 月度采购金额与环比
+
+```sql
+-- 当月采购总额
+SELECT COALESCE(SUM(total_amount), 0) AS currentMonthAmount
+FROM biz_purchase_order
+WHERE status IN ('confirmed', 'closed', 'delivered')
+  AND DATE_FORMAT(create_time, '%Y-%m') = DATE_FORMAT(NOW(), '%Y-%m');
+
+-- 上月采购总额（环比基准）
+SELECT COALESCE(SUM(total_amount), 0) AS lastMonthAmount
+FROM biz_purchase_order
+WHERE status IN ('confirmed', 'closed', 'delivered')
+  AND DATE_FORMAT(create_time, '%Y-%m') = DATE_FORMAT(DATE_SUB(NOW(), INTERVAL 1 MONTH), '%Y-%m');
+
+-- 环比 = (当月 - 上月) / 上月 * 100
+```
+
+#### 预算节省分析
+
+```sql
+-- 每个 RFQ 的预算 vs 实际采纳金额
+SELECT
+  r.rfq_id,
+  r.rfq_no,
+  r.rfq_title,
+  ri.total_expected AS expectedTotal,
+  COALESCE(q.total_amount, 0) AS acceptedQuote,
+  (ri.total_expected - COALESCE(q.total_amount, 0)) AS savedAmount
+FROM biz_rfq r
+JOIN (
+  SELECT rfq_id, SUM(quantity * expected_price) AS total_expected
+  FROM biz_rfq_item GROUP BY rfq_id
+) ri ON r.rfq_id = ri.rfq_id
+LEFT JOIN biz_quotation q ON r.rfq_id = q.rfq_id AND q.status = 'accepted'
+WHERE r.status = 'completed';
+```
+
+#### 供应商中标率
+
+```sql
+SELECT
+  q.supplier_id,
+  s.supplier_name,
+  COUNT(*) AS totalQuotes,
+  SUM(CASE WHEN q.status = 'accepted' THEN 1 ELSE 0 END) AS winCount,
+  ROUND(SUM(CASE WHEN q.status = 'accepted' THEN 1 ELSE 0 END) / COUNT(*) * 100, 1) AS winRate
+FROM biz_quotation q
+JOIN biz_supplier s ON q.supplier_id = s.supplier_id
+WHERE q.status IN ('accepted', 'rejected')
+GROUP BY q.supplier_id, s.supplier_name
+ORDER BY winRate DESC;
+```
+
+### 6.2 性能优化建议
+
+| 优化点 | 方案 |
+|--------|------|
+| **大数据量** | 报表查询加时间范围过滤，默认只查最近12个月 |
+| **缓存** | 看板数据用 Redis 缓存 5 分钟（利用 RuoYi 已有 Redis 集成） |
+| **复杂统计** | 新建物化视图或定时任务汇总到统计表（后续优化） |
+
+---
+
+## 七、权限与菜单设计
+
+### 7.1 权限标识
+
+| 权限标识 | 对应页面 | 说明 |
+|---------|---------|------|
+| `bid:report:list` | 统计分析目录 | 父菜单显示 |
+| `bid:report:dashboard` | 采购总览看板 | 仪表盘页面 |
+| `bid:report:cost` | 采购成本分析 | 成本页面 |
+| `bid:report:supplier` | 供应商绩效 | 供应商页面 |
+
+### 7.2 权限分配
+
+在系统管理 → 角色管理中，为管理员角色勾选新增的菜单权限：
+- 统计分析 → 采购总览看板
+- 统计分析 → 采购成本分析
+- 统计分析 → 供应商绩效
+

+## 附录：与老板汇报话术参考
+
+> **老板，我做了一个统计分析模块，分为三个页面：**
+>
+> 1. **采购总览看板** — 一打开就能看到本月花了多少钱、发了多少询价单、供应商活跃情况，还配了趋势图和排名。
+> 2. **采购成本分析** — 对比预算和实际花销，看哪些品类花钱多，每次比价节省了多少，一眼看清钱花在哪。
+> 3. **供应商绩效** — 给每个供应商打分排名（质量/交期/服务/价格），哪家好哪家差一目了然，还有异常统计。
+>
