我正在做我的UML圖嗎？

Question

所以如上所述，這是一個家庭作業問題，所以請在我身上輕鬆一下。基本上我必須爲兩個子系統創建一個用例圖。我已經掌握了它的主旨，但我無法區分這兩者，並且對它們如何相互關聯感到困惑。

Manufacturing 

Factory Operation 
Each internal factory organises itself into manufacturing modules. Each module has a module leader and a number of technicians. Many internal factories can make the same part. A part may be made up of other parts in which it is called an assembly. Each part has unique part number and a CAD/CAM drawing which is stored electronically. The drawing holds details such as issue number, sizes, materials and sub parts if it is an assembly. The manufacturing system holds a manufacturing route for each part. This details how the part should be made on the CNC machine in terms of manufacturing process (for instance lathe -2 hours, mill -3 hours, grind -1 hour , broach -1 hour, drill -1 hour, hardening - 1 hour, annealing -1 hour , plating - 0.5 hour). A schedule has to be set up by the module leader which states on a weekly basis what CNC machines will be used and who will use them, broken down by the hour. The module leader does this by looking at all the orders received at the beginning of the week and also considering any orders anticipated and the deadlines that have to be met. Changes sometimes need to be made to the schedule to cope with unexpected staff absence, delays or machine break down. The module leader has to forecast the raw materials (e.g. a bar of steel) needed to be bought in the make the parts on a daily basis. Orders for raw materials are to a single specialist supplier. The module leader uses forecasts, bill of materials and part manufacturing specifications to work out what raw materials are needed. Daily, weekly, monthly, quarterly and annual plans are made for raw materials. 

Traceability 
Traceability of components is very important in the aircraft industry. If a part fails  when in use, it is returned to the factory for a diagnosis. If the factory finds a fault in a component it must trace that component back to its original batch and perhaps recall all parts in the same batch. Every bar of metal has a batch number set by the supplier. If a technician makes a part from that bar of metal the bar’s batch number must be maintained for traceability. Parts also have a batch number. This is different to the batch number of the metal bars. The batch number of the metal bars are set by the supplier of the metal. The batch number of the parts are set by the factory. If a number of parts are made in one manufacturing run (which might involve a number of processes) they belong to the same batch. Typically the factory will receive an order for a number of parts and will keep all those parts in the same batch. This is to ensure good traceability from when the part fails in the air right back to the bar of metal that was used to make it. The part batch number is assigned when parts come off the manufacturing process and into store. 

Stores 
Each factory has a store for finished goods. When parts leave manufacturing they must be booked into store. When parts leave store they must be booked out. The store has a number of containers to hold the parts. The store needs to record where the parts are held (i.e. container number). Stores are responsible for despatching parts. 

對不起它沒有被格式化好，我不知道如何做到這一點。

任務：

**Manufacturing (Bill of Materials and Manufacturing Method)** 
Bill of Materials (how assemblies are composed), 
Manufacturing for each part (how each part must be manufactured) 

**Manufacturing (Scheduling and Traceability)** 
Machine Shop Scheduling (who is using which machine and when) 
Traceability (Batch numbers, linking to orders, booking into store when complete) 
Factory stores 

用例圖至今：

Answer 1

了UML沒有正確的概念。 According to this book，如果它表達了你用來解決問題的想法，uml是一個單詞，「正確」。

這裏有一些建議我會更好地傳達這個想法，其他人可能會不同意： 接收錯誤的部分應該be an extension of接收部分。
商店用戶是誰？ 誰是模塊的領導者？你可以再詳細一點嗎？ 書籍零件和記錄零件是否足夠相似以便組合？ 舉辦部分取決於說「訂購部分」 是什麼「設置批號」可選部分？如果是這樣，擴展是好的，但是如果設置批號是製造零件的必要步驟，則應使用「使用」或「包含」設置批次。
