fix(scheduling): fix vehicle type classification and algorithm candidate matching
- classifyVehicleType now parses dic_type.dic_name (e.g. "4.5吨冷链车") instead of raw model code - Remove overly strict completionRate >= 0.8 filter for hopeless candidates - Use vehicle's yearTarget as fallback when inventory has no assessment target - Filter out suggestions with no candidates (not actionable) - estimatedGain counts rescue_hopeless suggestions as potential gains Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

# 三大运营统计模块设计
|
||||
|
||||
从 lnoneos 原型迁移到 ln-bi 生产项目，使用真实 MySQL 数据。
|
||||
|
||||
## 架构决策
|
||||
|
||||
- **数据源**：复用现有 `getVehicles()` 缓存（~1000 辆，内存聚合无性能问题）
|
||||
- **跳过**：出勤率、日均里程（无数据源），QR Code
|
||||
- **新增图标**：`Search`, `Filter`, `ArrowRightLeft` (lucide-react，已安装)
|
||||
|
||||
## 模块 1：部门运营统计
|
||||
|
||||
### 后端 API
|
||||
|
||||
**`GET /api/vehicles/dept-stats`** — 返回 `DeptGroup[]`
|
||||
|
||||
聚合逻辑：按 `Vehicle.departmentName` 分组，每个部门下按 `Vehicle.customerManager` 分组。每个业务员统计车型分布：
|
||||
|
||||
| 车型类别 | 过滤条件 |
|
||||
|---|---|
|
||||
| t4_5 | type=4.5T 且 model 不含"冷链" |
|
||||
| t4_5c | type=4.5T 且 model 含"冷链" |
|
||||
| t18 | type=18T |
|
||||
| t49 | type=49T |
|
||||
| trailer | model 含"挂车" |
|
||||
| other | 以上都不是 |
|
||||
|
||||
部门级别额外字段：`totalAssets`（运营中的）、`operatingCount`（status=Operating）、`idleCount`（status=Inventory 或 Abnormal）。
|
||||
|
||||
### 后端：扩展 `/api/vehicles/list`
|
||||
|
||||
新增查询参数：
|
||||
- `manager` — 按客户经理筛选
|
||||
- `customer` — 按客户名称筛选
|
||||
- `isColdChain` — true/false，筛选冷链/非冷链
|
||||
- `isTrailer` — true/false，筛选挂车/非挂车
|
||||
|
||||
### 前端类型
|
||||
|
||||
```typescript
|
||||
interface ManagerStats {
|
||||
manager: string;
|
||||
department: string;
|
||||
t4_5: number;
|
||||
t4_5c: number;
|
||||
t18: number;
|
||||
t49: number;
|
||||
trailer: number;
|
||||
other: number;
|
||||
total: number;
|
||||
}
|
||||
|
||||
interface DeptGroup {
|
||||
department: string;
|
||||
totalAssets: number;
|
||||
operatingCount: number;
|
||||
idleCount: number;
|
||||
managers: ManagerStats[];
|
||||
}
|
||||
```
|
||||
|
||||
### 前端 UI
|
||||
|
||||
参照 lnoneos 1362-1880 行：
|
||||
- 顶部深色汇总条（总资产/运营中/闲置中，跳过平均出勤）
|
||||
- 按部门/按业务员切换
|
||||
- 桌面表格 + 移动端卡片
|
||||
- 展开部门显示业务员卡片，展开业务员显示 6 个车型格子（可点击下钻到车牌列表）
|
||||
|
||||
## 模块 2：区域运营统计
|
||||
|
||||
### 后端 API
|
||||
|
||||
**`GET /api/vehicles/region-stats`** — 返回 `RegionGroup[]`
|
||||
|
||||
新增大区映射函数（province/city → 华东/华南/华北/华中/西南/西北/其他）。按大区分组，每个区域下统计：
|
||||
- 按车型（4.5T/18T/49T）的资产/运营/库存数
|
||||
- 列出区域内的客户列表
|
||||
|
||||
```typescript
|
||||
interface RegionGroup {
|
||||
region: string; // 华东、华南等
|
||||
totalAssets: number;
|
||||
operatingCount: number;
|
||||
inventoryCount: number;
|
||||
customers: string[];
|
||||
typeBreakdown: { type: string; total: number; operating: number; inventory: number; customers: string[] }[];
|
||||
}
|
||||
```
|
||||
|
||||
### 前端 UI
|
||||
|
||||
参照 lnoneos 1882-2174 行：
|
||||
- 筛选弹出框（客户搜索/区域/城市下拉）
|
||||
- 可展开区域行，展开后显示车型子行
|
||||
- 桌面表格 + 移动端卡片
|
||||
|
||||
## 模块 3：客户运营统计
|
||||
|
||||
### 后端 API
|
||||
|
||||
**`GET /api/vehicles/customer-stats`** — 返回 `CustomerStats[]`
|
||||
|
||||
按 `Vehicle.customerName` 分组（只统计 status=Operating 的车辆），每个客户统计：
|
||||
- 关联业务员（customerManager）、品牌（brandLabel）、部门（departmentName）
|
||||
- 大区（从 province/city 映射）、城市
|
||||
- 6 个车型分列计数 + 合计
|
||||
|
||||
```typescript
|
||||
interface CustomerStats {
|
||||
customer: string;
|
||||
manager: string;
|
||||
brand: string;
|
||||
department: string;
|
||||
region: string;
|
||||
city: string;
|
||||
t4_5: number;
|
||||
t4_5c: number;
|
||||
t18: number;
|
||||
t49: number;
|
||||
trailer: number;
|
||||
other: number;
|
||||
total: number;
|
||||
}
|
||||
```
|
||||
|
||||
### 前端 UI
|
||||
|
||||
参照 lnoneos 2176-2496 行：
|
||||
- 筛选弹出框（客户名/业务员搜索，品牌/部门/区域下拉）
|
||||
- 翡翠绿色主题表头
|
||||
- 客户表格，各车型列可点击下钻
|
||||
- 展开后显示 4 个详情卡片（客户详情/主要车型/运营状态/资产占比）
|
||||
- 桌面表格 + 移动端卡片
|
||||
|
||||
## 文件变更清单
|
||||
|
||||
| 文件 | 变更 |
|
||||
|---|---|
|
||||
| `src/server/routes/vehicles.ts` | 新增 3 个 API 端点 + 扩展 `/list` 的过滤参数 + 大区映射函数 |
|
||||
| `src/types.ts` | 新增 `DeptGroup`, `ManagerStats`, `CustomerStats`, `RegionGroup` 接口 |
|
||||
| `src/server/types.ts` | 同步新增后端类型 |
|
||||
| `src/api.ts` | 新增 `fetchDeptStats`, `fetchRegionStats`, `fetchCustomerStats` |
|
||||
| `src/App.tsx` | 新增 3 个 section + 相关 state/toggle/filter 逻辑 + 扩展 showPlateNumbers 类型 |
|
||||
|
||||
## 实现顺序
|
||||
|
||||
1. 后端：大区映射 + 3 个 API + 扩展 list 过滤
|
||||
2. 前端类型 + API 客户端
|
||||
3. 部门运营统计 UI
|
||||
4. 区域运营统计 UI
|
||||
5. 客户运营统计 UI
|
||||
6. 验证构建通过
