Product structure modeling
A product structure is a hierarchical decomposition of a product, typically known as the bill of materials (BOM). As business becomes more responsive to unique consumer tastes and derivative products grow to meet the unique configurations, BOM management can become unmanageable. For manufacturers, a bill of materials (BOM) is a critical product information record that lists the raw materials, assemblies, components, parts and the quantities of each needed to manufacture a product.
Advanced modeling techniques are necessary to cope with configurable products where changing a small part of a product can have multiple impacts on other product structure models. Concepts within this entry are in capital letters in order to indicate these concepts.
Several concepts are related to the subject of product structure modeling. All these concepts are discussed in this section. These concepts are divided into two main aspects. First the product breakdown is discussed which involves all the physical aspects of a product. Second, different views at the product structure are indicated.
Figure 1 illustrates the concepts that are important to the structure of a product. This is a meta-data model, which can be used for modeling the instances in a specific case of product structuring.
The core of the product structure is illustrated by the product components (items) and their relationships. Thus, this involves the linking between items related to the product. The assembly can consist of subassemblies and parts, whereas subassemblies can also consist of other subassemblies or part. Thus, this is typically hierarchically ordered. These concepts are generalized into the concept of item. This classification is overlapping, because a subassembly could be a part in another assembly configuration. Due to differentiation and variation of items several concepts must be indicated into the product breakdown structure. Three concepts are involved in this differentiation, namely alternatives, variants and revisions. An alternative of an item is considered as a substitute for that particular item, whereas a variant is another option of an item which the consumer can choose. When an error occurs at a part or subassembly, it needs to be revised. This revision indicates the change history of the item.
Product structure views are made upon several activity domains within the company. Due to the fact not everyone in the company has to have a detailed overview of the product several components with their attributes can be extracted.
When the Master Structure is made out of the several items of the product assembly, multiple views can be made upon this Master Structure. Thus this Master Structure contains every item in detail, which is important to the Assembly of the product.
The process of constructing the product model consists of six main activities, which can be decomposed in several sub-activities. The next table describes these activities and the sub-activities within them provided with a description about this activity.
