(1) narrow BOM and broad BOM

Bill of Manufacturing)

BOM in the narrow sense is generally called a bill of materials, that is, the product structure of the product structure. The physical structure of a material is simply decomposed according to certain rules, and the material composition of the material is described. Generally, layers are divided and described according to functions.

In a broad sense, Bom is a combination of product structure and process flow, which are inseparable. To objectively and scientifically describe a product in a manufacturing industry through Bom, you must start with the manufacturing process to accurately describe the organization of the system product.

BOM (Bill of manufacturing) = process flow (Routing) (= set of processes) (= set of Work Centers) --- work center equipment and personnel + product structure (prod. structure) (= a collection of materials) --- material cost information

(1) substitute material: Replace the originally set material in the BOM according to a certain proportion.

(2) An alternative process path can be set for one or more continuous processes in a process route. To replace the process in the process path, you can set the material usage to form a partial BOM of the product.

(3) The alternative process path can still be added after the process route review to solve the process change problem during production.

(4) alternative materials can still be defined after BOM review.

(5) the more formal approach should be engineering change.

Engineering change is one of the important control items for enterprise activities. According to the implementation time and purpose, the control details are as follows: generally, after the completion of a new product, the non-engineering unit will issue a project change request and submit it to the engineering unit for research. If the engineering unit agrees, it will issue an ECO and submit it to each unit for signature, and then import the data. ECN (Engineering Change notice) Engineering Change Notification: engineering changes typically used in the new product development process are issued after the Engineering Department confirms the change and notifies the relevant units. Engineering Change order (engineering change order) Engineering Change command: usually used for engineering changes after the completion of new product development. After the Engineering Department confirms the necessary changes, it issues a document to the relevant organization for signing, in order to ensure that the inventory and In-process items are properly handled, the items are changed immediately and after use. The sales unit, manufacturing unit, and material unit must agree and take necessary actions, generally, ECOs involve a large scope and long import time, which requires rigorous system management. ECA (Engineering Change authority) engineering change authorization: in some cases, engineering changes must be authorized by the customer. In this case, the ECA must be issued and the customer needs to sign back as the basis for the ECO.

(1) ticket creation process adjustment: transfer ticket --> outsourcing order --> transfer ticket --> change the outsourcing ticket to transfer order --> outsourcing ticket --> transfer ticket

(2) When selecting a window, you must specify the format of the window.

(3) try to use the dynamic object structure when writing a document. The sentence should be short and easy to understand.

Share a sentence: knowing and knowing, benevolence cannot be kept, even if it is obtained, it will be lost. The origin of mr. Yang Ming's name -- Wang shouren
