Part Master
A list of parts with their attribute values and associated objects
- consists of key attributes: part number, version, name, status, type, create date and owner.
- The part number could have meanings but, difficult to manage them.
- The part version differenciates two parts but maintain certain relationship such as inter-operable parts.
- The part name or description could be standardized with pre difined words for the language translation in the multi-lagnueage catalogue
- The status indicates the position of part in its life cycle. Sequrity, release and applicability management could use the attribute.
- The type shows the production methods of the part. They include purchasing, fablication and semi-assemby. This will be used to interface to the ERP and Customer support part managment systems.
- The owner and date can be used for the sequrity control.
- Create, delete, update, version up operations
- Associated Objects: Service object, Purchase object (Duplicated), Drawing objects (meta data for drawings)
- Design - Part No, Version, Name, Material, Weight, Price, Documents
- Manufacturing - Standard part, Purchasing Info
- Service - Part Planning, CS Purchasing, Package Size
- Supplier - Part Spec, Drawing, Price
Tasks:
- Build a part master of the simple ball point pen.

Product Structure Managment
Tree like set of constituent relationship between parts which consists of end-product
- End-product and assembly
- Constituent relationship between an assembly and component parts
- Quantity per data on the relationship (consider DMU)
- Introduction of options as a virtual level in the product structure (optional)
- Variant and effectivity for muti-product structure representation (optional)
- Add, cut and replace operations of product structure.
- Get parent and Where used operations
- Nevigation with effectivity (optional)
- Consider MBOM and CSBOM.
- Change Managment of the Product Structure (see lesson 6)
- Marketing - Model and option code generation
- Design - Product structure, quantity
- Manufacturing - Part planning
- Service - Part Planning, quantity
- Supplier - Part structure, qty
Tasks:
- Build a product structure of the simple ball point pen.
- Edit the product structure with add, cut and replace operations
- Introduct options to the products structure to represent product family (optional)
- Apply the get parent and where used operation on a part in the product structure.
- Classify and prepare Mfg and CS parts from the product structure.
An Example
| PARENT_PART_NO | 16500150 |
| PARENT_PART_VERSION | --A |
| CHILD_PART_NO | 16500176 |
| CHILD_PART_VERSION | --- |
| QTY | 3 |
Document Management
- Engineering drawings (CAD Models, Images), Engineering Documents
- Need proper acess control
- Support long duration transaction - Check in/check out
- Storage methods:
file outside database - simple and no translation, no concurrnt contol
BLOB in database - need translation, advantage in sequrity control, can use the database client
Tasks:
- Simulate check in/out in the virtual PIM system on a paper
- Simulate the two document storage approach in the virtual PIM system on a paper
An Example
| DRAWING_NO | 16500150 |
| REVISION | --A |
| SIZE | A4 |
| SHEET | 1/1 |
| PRIME | 3 |
| TYPE | MS WORD 7.0 |
