' ========================================
' 类模块: clsBOMManager
' 用途: 管理整个BOM数据结构
' 功能:
' 1. 加载和组织BOM数据
' 2. 建立类别层级关系
' 3. 提供物料查询接口
' 4. 支持领料逻辑处理
' ========================================
Option Explicit
' ========================================
' 私有成员变量
' ========================================
Private dictCategories As Object ' Dictionary对象: 类别名称 -> clsCategory对象
' 作用: 快速查找任意类别
Private dictAllMaterials As Object ' Dictionary对象: 物料代号 -> clsMaterialItem对象
' 作用: 快速查找任意物料
Private rootCategories As collection ' Collection: 存储所有顶层类别(无父类别的类别)
' 作用: 遍历完整的类别树结构
' ========================================
' 类初始化
' 说明: 创建BOMManager实例时自动调用
' ========================================
Private Sub Class_Initialize()
Set dictCategories = CreateObject("Scripting.Dictionary")
Set dictAllMaterials = CreateObject("Scripting.Dictionary")
Set rootCategories = New collection
End Sub
' ========================================
' LoadData 方法
' 功能: 从[平台配置清单]工作表加载BOM数据并构建数据结构
' 参数:
' wsPlatform - [平台配置清单]工作表对象,包含完整的物料信息和类别配置
' 表结构: 行号|模块|代号|名称|数量|选择条件|备注|类别|上层类别|类别选用条件|66代码
' 数据从第4行开始(前3行是标题)
' 处理步骤:
' 1. 从[平台配置清单]一次性加载所有物料信息和类别信息
' 2. 建立类别的父子关系,构建层级树
'
' 重要说明:
' - 所有数据都从[平台配置清单]读取,不再需要[领料配置]表
' - 只有"类别"字段不为空的物料才会被添加到类别中
' - "类别选用条件"用于判断该类别是否需要(为空表示总是需要)
' - "66代码"是66系统使用的代码
' ========================================
Public Sub LoadData(wsPlatform As Worksheet)
Dim i As Long, lastRow As Long
Dim mat As clsMaterialItem
Dim cat As clsCategory
' ========================================
' 第一步: 从平台配置清单加载所有物料和类别信息
' 说明:
' 读取列说明:
' - C列(代号)、D列(名称)、E列(数量)、F列(选择条件)
' - H列(类别)、I列(上层类别)、J列(类别选用条件)、K列(66代码)
' - 从第4行开始读取(前3行是标题)
'
' 处理逻辑:
' 1. 所有物料都存入dictAllMaterials字典(包括无类别的物料)
' 2. 只有"类别"字段不为空的物料才创建类别并添加到类别中
' 3. 类别对象保存CategorySelectCondition属性
' 4. 物料对象保存CategorySelectCondition和Code66属性
' ========================================
lastRow = wsPlatform.Cells(wsPlatform.Rows.Count, "C").End(xlUp).row
For i = 4 To lastRow ' 从第4行开始(跳过标题)
' 1. 创建物料对象并读取基础信息
Set mat = New clsMaterialItem
mat.code = Trim(wsPlatform.Cells(i, "C").value & "") ' 物料代号
mat.Name = Trim(wsPlatform.Cells(i, "D").value & "") ' 物料名称
On Error Resume Next
mat.Quantity = CDbl(wsPlatform.Cells(i, "E").value) ' 物料数量
On Error GoTo 0
mat.Condition = Trim(wsPlatform.Cells(i, "F").value & "") ' 选择条件
' 2. 读取类别相关字段
Dim catName As String
Dim parentCatName As String
Dim catSelectCond As String
Dim code66 As String
catName = Trim(wsPlatform.Cells(i, "H").value & "") ' 类别
parentCatName = Trim(wsPlatform.Cells(i, "I").value & "") ' 上层类别
catSelectCond = Trim(wsPlatform.Cells(i, "J").value & "") ' 类别选用条件
code66 = Trim(wsPlatform.Cells(i, "K").value & "") ' 66代码
' 3. 保存类别相关属性到物料对象
mat.Category = catName
mat.ParentCategory = parentCatName
mat.CategorySelectCondition = catSelectCond
mat.Code66 = code66
' 4. 将物料保存到字典(所有物料都保存,包括无类别的)
If mat.code <> "" Then
Set dictAllMaterials(mat.code) = mat
End If
' 5. 如果物料有类别,创建或更新类别对象,并将物料添加到类别
If catName <> "" Then
' 确保类别对象存在(如果类别不存在则创建)
If Not dictCategories.Exists(catName) Then
Set cat = New clsCategory
cat.categoryName = catName
cat.ParentCategoryName = parentCatName
cat.CategorySelectCondition = catSelectCond ' ⭐ 设置类别选用条件
Set dictCategories(catName) = cat
End If
' 将物料添加到类别
dictCategories(catName).AddMaterial mat
End If
Next i
' ========================================
' 第二步: 建立类别层级关系
' 说明:
' - 遍历所有类别,根据ParentCategoryName建立父子关系
' - 如果类别有父类别,将自己添加到父类别的SubCategories中
' - 如果类别没有父类别,则为根类别,添加到rootCategories中
' 结果:
' - 构建完整的树形结构
' - rootCategories包含所有顶层类别
' - 每个类别的SubCategories包含其直接子类别
' ========================================
Dim key As Variant
For Each key In dictCategories.Keys
Set cat = dictCategories(key)
If cat.ParentCategoryName <> "" Then
' 有父类别,建立父子关系
If dictCategories.Exists(cat.ParentCategoryName) Then
Dim parentCat As clsCategory
Set parentCat = dictCategories(cat.ParentCategoryName)
parentCat.AddSubCategory cat ' 将当前类别添加为父类别的子类别
End If
Else
' 无父类别,是根类别
rootCategories.Add cat, cat.categoryName
End If
Next key
End Sub
' ========================================
' GetRootCategories 方法
' 功能: 获取所有顶层类别的集合
' 返回: Collection对象,包含所有无父类别的clsCategory对象
' 用途:
' - 遍历整个BOM结构时的入口点
' - 生成领料清单时遍历所有根类别
' 示例:
' Dim cats As Collection
' Set cats = bomMgr.GetRootCategories()
' For i = 1 To cats.Count
' Debug.Print cats(i).CategoryName
' Next i
' ========================================
Public Function GetRootCategories() As collection
Set GetRootCategories = rootCategories
End Function
' ========================================
' GetCategory 方法
' 功能: 根据类别名称获取类别对象
' 参数:
' categoryName - 要查询的类别名称(字符串)
' 返回:
' clsCategory对象 - 如果找到
' Nothing - 如果未找到
' 用途: 快速查找特定类别及其下的物料
' 示例:
' Dim cat As clsCategory
' Set cat = bomMgr.GetCategory("部件")
' If Not cat Is Nothing Then
' Debug.Print cat.Materials.Count & " 个物料"
' End If
' ========================================

' ========================================
' GetMaterialsForPicking 方法
' 功能: 获取某类别下需要领料的物料清单(考虑层级逻辑)
' 参数:
' categoryName - 类别名称
' useParent - 可选参数,默认True
' True: 使用父类别物料(默认领料方式)
' False: 使用子类别物料(库存不足时的替代方案)
' 返回: Collection对象,包含clsMaterialItem对象
'
' 业务逻辑说明:
' 1. 默认领取父类别的物料(如"低压接头部件")
' 2. 当父类别库存不足时,才领取子类别的物料(如"接头"+"弹性元件")
' 3. 如果useParent=True但类别有子类别,仍返回父类别物料
' 4. 如果useParent=False,递归获取所有子类别的物料
'
' 示例1: 获取"部件"类别的物料(父类别)
' Set mats = bomMgr.GetMaterialsForPicking("部件", True)
' ' 返回: 低压接头部件、高压接头部件等组装好的部件
'
' 示例2: 获取"部件"类别的物料(子类别展开)
' Set mats = bomMgr.GetMaterialsForPicking("部件", False)
' ' 返回: 径向低压接头、弹簧管、螺旋管等零件
' ========================================

' ========================================
' 使用父类别物料(默认领料方式)
' 说明:
' - 直接返回当前类别下的所有物料
' - 即使该类别有子类别,也仍然返回父类别物料
' - 这是正常情况下的领料方式(领取组装好的部件)
' ========================================

For i = 1 To cat.materials.Count

Next i
Else
' ========================================
' 使用子类别物料(库存不足时的替代方案)
' 说明:
' - 如果当前类别有子类别,递归获取所有子类别的物料
' - 如果当前类别是叶子类别(无子类别),返回本类别物料
' - 这用于父类别库存不足,需要领取零件自行组装的情况
' 示例:
' 当"低压接头部件"库存不足时
' 改为领取"径向低压接头"+"弹簧管"零件

' 说明:
' - 使用缩进显示类别层级(每层2个空格)
' - 递归打印所有子类别和物料
' - 便于验证数据结构是否正确
' 示例输出:

' - 01091004312 表壳(本色) 数量:1 条件:
' 部件 (物料数:20)
' - 01011019001 低压接头部件 数量:1 条件:lcfw=M02...

' ========================================
' GetMaterialsByModel 方法
'
' 【功能概述】
' 根据产品型号字符串自动解析规格参数,并返回符合这些规格的所有物料清单。
' 这是BOM系统的核心方法,实现了从"产品型号"到"物料清单"的智能转换。
'
' 【工作流程】
' 1. 型号解析 (clsModelParser) → 将产品型号字符串拆解为结构化参数
' 2. 条件提取 (clsConditionExtractor) → 从型号参数中提取匹配条件变量
' 3. 物料筛选 (clsConditionMatcher) → 根据条件从物料库中筛选符合条件的物料
'
' 【参数说明】
' modelStr - 产品型号字符串
' 格式: [型号]-[口径].[安装].[表壳].[连接].[量程]|[表盘]|[附件]|[法兰]
' 示例: "YTHN-100.A0.532.M203.M16.Y3|BP-095.2312.M16.PA3"
' 说明: 必须是完整的型号字符串,不能为空
'
' categoryName - 类别名称(可选参数,默认为空字符串)
' 为空字符串 "": 返回所有类别的符合条件物料(默认行为)
' 指定类别名: 仅返回该类别下的符合条件物料
' 示例: "部件"、"表壳"、"接头"、"机芯"
'
' autoFallback - 是否自动降级到子类别(可选参数,默认为True)
' True (默认): 当某个类别无匹配物料时,自动降级到其子类别继续查找
' False: 仅在当前类别查找,不降级到子类别
' 示例场景:
' 型号 "YTHN-100.A0.532.M203.M17.Y3" 的量程是M17
' 类别"部件"下的物料条件是 "lcfw=M02"
' autoFallback=True: 自动降级到子类别"接头"、"弹性元件"等查找
' autoFallback=False: "部件"类别返回空集合
'
' 【返回值】
' 返回类型: Collection对象
' 元素类型: Collection中的每个元素都是 clsMaterialItem 对象
'
' clsMaterialItem 对象属性:
' .code - String - 物料代号(如: "01011019001")
' .Name - String - 物料名称(如: "低压接头部件")
' .Quantity - Double - 物料数量(如: 1, 2, 0.5)
' .Condition - String - 选择条件(如: "lcfw=M02 AND gclj=Z12")
' .Category - String - 所属类别名称
' .ParentCategory - String - 上层类别名称
'
' 【注意事项】
' 1. 调用前必须先执行 LoadData() 方法加载BOM数据
' 2. 型号字符串必须完整且符合格式要求
' 3. 返回的Collection可能为空(没有符合条件的物料),需要判断Count属性
' 4. 调试信息会输出到VBA的"立即窗口"(Ctrl+G查看)
' 5. 物料的Condition属性为空表示该物料无条件限制(所有型号都使用)
' 6. autoFallback 参数影响查找范围:
' - True (默认): 会返回父类别和子类别的物料,更全面但可能包含不需要的物料
' - False: 仅返回指定类别的物料,更精确但可能遗漏子类别的替代物料
'
' 【相关方法】
' - GetMaterialsByCategoryAndModel: 结合了类别层级逻辑的物料获取
' - GetMaterialsForPicking: 纯粹按类别获取物料(不进行型号匹配)
' - ParseModelAndExtractConditions: 仅解析型号并返回条件字典
' ========================================
Public Function GetMaterialsByModel(modelStr As String, _

' 判断逻辑:
' 遍历所有类别,对每个类别调用 IsRequiredForModel(conditions) 方法:
' - 如果类别选用条件为空 → 该类别总是需要,添加到结果集

' GetValidMaterialsByModel 方法
' 功能: 根据产品型号获取物料，并判断是否为完整的物料集合
' 参数:

' (2) "IsComplete" - Boolean值,指示物料是否完整

' - 对于每个需要的类别(顶层类别或其需要领取的子类别)
' - 必须有且仅有一个物料被匹配
' - 如果某个需要的类别有0个或多于1个物料,则视为不完整
' - 不需要的类别不参与完整性检查

' 假设型号为 "YTHN-100.A0.532.M203.M16.Y3" (量程M16, 过程连接M20)
'
' 类别1: CategorySelectCondition = "" → 总是需要
