In a classic structure, the product tree, route, and factory structure are defined separately and linked to each other by reference. In high-variation production, this approach quickly becomes unmanageable: each new variant means a new tree, a new route, and a new maintenance burden.
Integrated product and process engineering is an approach that defines product structure, process structure, and factory structure in a single integrated model . Variants do not multiply as separate trees; they are derived within a single structure using selection rules.
Three structures
Product structure
The functional and physical components of the product; variant options and their interdependencies. "What parts might be in this product?"
Process structure
The operations and activities required to produce the product; which component is used in which activity. "How is this product made?"
Factory structure
Lines, stations, and resources; the physical location where the activities take place. "Where is this work done?"
Scope and benefits
Variant management: Deriving hundreds of product variants from a single structure instead of separate trees; preventing exponentially increasing maintenance costs.
Component-activity relationship: Direct modeling of which assembly step each part is used in; accurate planning of line-side feeding.
Line balancing: Assigning activities to stations via the model and testing alternative distributions.
Single point of change management: When a component changes, all affected variants and stations are automatically identified.
Time dimension: Managing the structure with validity dates; planning which configuration will be produced from which date.
Design and production bridge: Ensuring a structured and traceable transition from engineering to production.
Who needs it?
This approach is not mandatory for every business. The real benefit is seen in businesses with high variation, assembly-intensive, and in-line production : automotive and related industries, white goods, machinery manufacturing, elevators, furniture, and similar sectors.
If product variety is limited, the classic product tree and route structure is sufficient and simpler. The correct question is not "should we use this capability?" but "does the number of variants make managing separate trees unsustainable?"
Benefit to the customer
The time it takes to identify new variants will decrease from days to hours.
The main data maintenance burden does not grow proportionally with the number of variants.
The effect of the change is applied consistently across all variants.
Line balancing and feeding plans can be created using the model.
