会社の新事業年度が始まって早2週間と･･･。
その中で会社を先週休んでしまったけど、それなりにラッシュで片付けないといけない案件が出てきた・・・。
また聞きなれない言葉が登場・・・ぼむ。
例の通り、Wikipediaから引用すると･･･。
Bill of materials (BOM) is a list of the raw materials, sub-assemblies, intermediate assemblies, sub-components, components, parts and the quantities of each needed to manufacture an end item (final product) .
ズバリ、シンプル、ストレートに言えば、「料理の具」のリスト的なものと言う理解か。。
It may be used for communication between manufacturing partners, or confined to a single manufacturing plant.
僕の勤め先は明らかに後者ゆえ・・・。
A BOM can define products as they are designed (engineering bill of materials), as they are ordered (sales bill of materials), as they are built (manufacturing bill of materials), or as they are maintained (service bill of materials). The different types of BOMs depend on the business need and use for which they are intended. In process industries, the BOM is also known as the formula, recipe, or ingredients list. In electronics, the BOM represents the list of components used on the printed wiring board or printed circuit board. Once the design of the circuit is completed, the BOM list is passed on to the PCB layout engineer as well as component engineer who will procure the components required for the design.
僕の単純な理解で間違いなさそう。。
BOMs are hierarchical in nature with the top level representing the finished product which may be a sub-assembly or a completed item. BOMs that describe the sub-assemblies are referred to as modular BOMs. An example of this is the NAAMS BOM that is used in the automative industry to list all the components in an assembly line. The structure of the NAAMS BOM is System, Line, Tool, Unit and Detail.
製造業で一般的に使われていそうな感じ。自動車産業とはまた違うだろうけど、仕事を通じて基本のコンセプトは押さえられた(はず)。
The first hierarchical databases were developed for automating bills of materials for manufacturing organizations in the early 1960s.
A bill of materials "implosion" links component pieces to a major assembly, while a bill of materials "explosion" breaks apart each assembly or sub-assembly into its component parts.
A BOM can be displayed in the following formats:
A single-level BOM that displays the assembly or sub-assembly with only one level of children. Thus it displays the components directly needed to make the assembly or sub-assembly.
An indented BOM that displays the highest-level item closest to the left margin and the components used in that item indented more to the right.
Modular (planning) BOM
A BOM can also be visually represented by a product structure tree, although they are rarely used in the workplace.
Single-levelは仕事で経験済・・・。
前事業年度通年での、原料消費量、(間接)材料使用量を製品製造量で割ることでまずは本社側でドラフトを作成済と。それをもって製造側と議論に臨むと。いくら単一商品の製造会社と言えど、原料から1ステップで最終商品ができるわけでないので仕掛品というか中間品の在庫も考慮せにゃならんのと、ただ中間品在庫は月ごとに増減を繰り返すので考慮しなくていいという両方の考え方があると。後者の場合はシンプルにできるので楽と言えば楽。ちょっと考慮しなくていいor考慮するの違いについてはもうちょい頭を冷やしてから考えてみたいところ。
とにかく最終製品を1作るためにどういう材が必要で、そこに調達単価を掛けてしまえば、標準原価が設定されると。
以上、今日の備忘録ということで・・・。
