# 订单物料提取功能实现计划
|
||||
|
||||
## 一、项目概述
|
||||
|
||||
### 1.1 目标
|
||||
实现从产品型号中提取选择条件，并根据条件匹配 BOM 库中对应的物料，生成订单物料清单。
|
||||
|
||||
### 1.2 核心功能
|
||||
1. **型号解析**：从产品型号中提取选择条件变量
|
||||
2. **条件匹配引擎**：解析并匹配物料的选择条件表达式
|
||||
3. **物料清单生成**：整合上述功能，生成符合产品配置的物料清单
|
||||
|
||||
---
|
||||
|
||||
## 二、产品型号编码规则
|
||||
|
||||
### 2.1 型号结构
|
||||
```
|
||||
[型号] - [公称外径] . [安装形式] . [壳体形式] . [过程连接&接液材质] . [量程范围] . [仪表特性] | [表盘] | [附件] | [法兰隔膜]
|
||||
```
|
||||
|
||||
### 2.2 示例分析
|
||||
**输入**: `YTHN-100.A0.532.M203.M16.Y3|BP-095.2312.M16.PA3`
|
||||
|
||||
**表头部分**: `YTHN-100.A0.532.M203.M16.Y3`
|
||||
|
||||
| 部位 | 代码 | 含义 |
|
||||
|------|------|------|
|
||||
| 型号 | YTHN | 不锈钢耐震压力表 |
|
||||
| 公称外径 | 100 | 100mm |
|
||||
| 安装形式 | A0 | 径向无边 |
|
||||
| 壳体形式 | 532 | 532系列(304外壳、内卡式) |
|
||||
| 过程连接&接液材质 | M203 | M20螺纹 + 3号材质(304) |
|
||||
| 量程范围 | M16 | 0～60 MPa |
|
||||
| 仪表特性 | Y3 | 硅油C充油 |
|
||||
|
||||
---
|
||||
|
||||
## 三、需求分析
|
||||
|
||||
### 3.1 提取的选择条件
|
||||
|
||||
| 变量名 | 变量标签 | 提取位置 | 提取规则 |
|
||||
|--------|----------|----------|----------|
|
||||
| gclj | 过程连接 | 过程连接&接液材质 | 除最后一位外的字符 |
|
||||
| jycz | 接液材质 | 过程连接&接液材质 | 最后一位数字 |
|
||||
| lcfw | 量程范围 | 量程范围 | 完整代码 |
|
||||
|
||||
### 3.2 提取示例
|
||||
|
||||
**输入**: `M203`
|
||||
- 过程连接(gclj): `M20`
|
||||
- 接液材质(jycz): `3`
|
||||
|
||||
**输入**: `M16`
|
||||
- 量程范围(lcfw): `M16`
|
||||
|
||||
### 3.3 匹配逻辑
|
||||
|
||||
#### 物料选择条件类型
|
||||
1. **无条件**：条件为空，表示该物料适用于所有配置
|
||||
2. **简单条件**：单个条件判断
|
||||
- 例: `lcfw=M01`
|
||||
3. **AND 条件**：多个条件同时满足
|
||||
- 例: `lcfw=M02 AND gclj=M20`
|
||||
4. **OR 条件**：任一条件满足即可
|
||||
- 例: `lcfw=M01 OR lcfw=M02 OR lcfw=M03`
|
||||
5. **NOT 条件**：排除特定条件
|
||||
- 例: `lcfw=M02 AND gclj!=M20`
|
||||
6. **复杂条件**：AND、OR、NOT 混合
|
||||
- 例: `gclj=Z12 AND (lcfw=M01 OR lcfw=M02 OR lcfw=M03)`
|
||||

' 主入口：生成订单物料清单
|
||||
Sub GenerateOrderMaterialList()
|
||||
Dim modelCode As String
|
||||
modelCode = InputBox("请输入产品型号:", "生成订单物料清单")

||||
|
||||
' 快速打印到立即窗口
|
||||
Sub QuickPrintOrderMaterials()
|
||||
Dim modelCode As String
|
||||
modelCode = InputBox("请输入产品型号:", "快速打印订单物料")
|
||||
|
||||
If modelCode = "" Then Exit Sub
|
||||
|

' ... 实现逻辑
|
||||
End Sub
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 六、数据流程图
|
||||
|
||||
```
|
||||
用户输入产品型号
|
||||
↓
|
||||
[clsModelParser] 解析型号
|
||||
↓
|
||||
提取选择条件字典 {gclj: M20, jycz: 3, lcfw: M16}
|
||||
↓
|
||||
[clsOrderMaterialList] 生成物料清单
|
||||
↓
|
||||
遍历所有根类别
|
||||
↓
|
||||
对每个类别调用 [clsBOMManager.GetMaterialsByConditions()]
|
||||
↓
|
||||
遍历类别下的所有物料
|
||||
↓
|
||||
对每个物料使用 [clsConditionEvaluator.Evaluate()]
|
||||
↓
|
||||
匹配成功 → 添加到结果集合
|
||||
匹配失败 → 跳过
|
||||
↓
|
||||
汇总所有匹配物料
|
||||
↓
|
||||
输出到工作表 / 立即窗口
|
||||
```

|
||||
|
||||
## 七、关键技术难点
|
||||
|
||||
### 7.1 条件表达式解析
|
||||
|
||||
**难点**:
|
||||
- 支持括号嵌套
|
||||
- 运算符优先级处理
|
||||
- 复杂逻辑组合
|
||||
|
||||
**解决方案**:
|
||||
- 使用递归下降分析法
|
||||
- 构建抽象语法树(AST)
|
||||
- 后序遍历求值
|
||||
|
||||
### 7.2 型号格式多样性
|
||||
|
||||
**难点**:
|
||||
- 部分型号可能缺少某些部分
|
||||
- 附件和法兰隔膜数量不固定
|
||||
- 过程连接代码长度不固定
|
||||
|
||||
**解决方案**:
|
||||
- 使用正则表达式（如果 VBA 支持）
|
||||
- 分段解析，容错处理
|
||||
- 提供默认值
|
||||
|
||||
### 7.3 性能优化
|
||||
|
||||

## 八、测试计划
|
||||
|
||||
### 8.1 单元测试
|
||||
|
||||
每个类都需要独立的单元测试模块：
|
||||
|
||||
1. **TestModelParser**: 测试型号解析功能
|
||||
2. **TestConditionEvaluator**: 测试条件求值功能
|
||||
3. **TestBOMManagerConditions**: 测试 BOM 管理器扩展功能
|
||||
4. **TestOrderMaterialList**: 测试订单物料清单生成功能
|
||||
|
||||
### 8.2 集成测试
|
||||
|
||||
测试完整的订单物料生成流程：
|
||||
|
||||
1. 测试标准型号
|
||||
2. 测试特殊配置型号
|
||||
3. 测试边界条件
|
||||
4. 测试异常输入
|
||||
|
||||
### 8.3 测试数据集
|
||||
|
||||
基于真实订单数据准备测试用例：
|
||||
|
||||
| 测试用例 | 型号 | 预期匹配物料数 |
|
||||
|----------|------|----------------|
|
||||
| 标准配置 | YTHN-100.A0.532.M203.M16.Y3 | 待定 |
|
||||
| 不同螺纹 | YTHN-100.A0.532.Z121.M06.Y3 | 待定 |
|
||||
| 小量程 | YTHN-100.A0.532.M201.M02.Y3 | 待定 |
|
||||
| 大量程 | YTHN-100.A0.532.M201.M16.Y3 | 待定 |
|
||||

|
||||
|
||||
## 九、文档需求
|
||||
|
||||
### 9.1 代码注释
|
||||
- 所有类模块需要详细的中文注释
|
||||
- 关键算法需要解释说明
|
||||
- 复杂逻辑需要举例说明
|
||||
|
||||
### 9.2 使用说明
|
||||
创建 `订单物料清单使用说明.md`，包括：
|
||||
- 功能概述
|
||||
- 使用方法
|
||||
- API 文档
|
||||
- 常见问题
|
||||
|
||||
### 9.3 开发文档
|
||||
- 类设计文档
|
||||
- 接口定义文档
|
||||
- 测试报告

|
||||
|
||||
| 阶段 | 任务 | 预计工作量 |
|
||||
|------|------|------------|
|
||||
| 1 | 型号解析器 | 2-3 天 |
|
||||
| 2 | 条件表达式求值器 | 3-4 天 |
|
||||
| 3 | BOM管理器扩展 | 1-2 天 |
|
||||
| 4 | 订单物料清单管理器 | 2-3 天 |
|
||||
| 5 | 订单处理模块 | 1-2 天 |
|
||||
| 6 | 测试与调试 | 2-3 天 |
|
||||
| 7 | 文档编写 | 1-2 天 |
|
||||
|
||||
**总计**: 约 12-19 天
|
||||

|
||||
## 十一、风险评估
|
||||
|
||||
### 11.1 技术风险
|
||||
- **风险**: VBA 不支持复杂的字符串处理
|
||||
- **应对**: 使用 VBScript Regular Expression 对象
|
||||
|
||||
### 11.2 数据风险
|
||||
- **风险**: BOM 数据不完整或格式错误
|
||||
- **应对**: 增加数据验证和容错处理
|
||||
|
||||
### 11.3 性能风险
|
||||
- **风险**: 大量物料匹配导致响应缓慢
|
||||
- **应对**: 优化算法，增加缓存机制
|
||||
|

|
||||
|
||||
## 十二、后续扩展方向
|
||||
|
||||
1. **批量订单处理**: 支持从 Excel 列表批量生成物料清单
|
||||
2. **条件配置化**: 将提取规则配置化，支持动态调整
|
||||
3. **物料替代方案**: 支持物料替代品推荐
|
||||
4. **库存集成**: 与库存系统集成，实时查询可用库存
|
||||
5. **成本计算**: 根据物料清单计算订单成本
