Exploring Design-To-Cost in Vehicle Engineering using Altair’s Enterprise Solution: HiQube

New innovative vehicle concepts in close connection to a steadily increasing product complexity as well as rising quality demands under extreme time pressure require a strong consideration of cost management whilst satisfying functional requirements. Considering “cost” solely, it needs to be understood as an equally important design variable as 70% of the later on occurring production and product cost will be determined in the conceptual design phase. However, designers usually feel less comfortable in dealing with cost criteria relating it to a set of specific technical or design changes. Mainly, this challenge arises from the fact that cost has traditionally been on the focus of the accountant rather than on the engineers.

Therefore, tools are required which allow engineers to efficiently move and explore the multi dimensional design space in terms of functionality and related cost simultaneously. HiQube represents such a tool as it allows an enterprise to fully leverage its “knowledge capital”. It provides a powerful, flexible data analytics solution that can grow with an organization’s Business Intelligence (BI) maturity model. Through advanced functionality like block operations and embedded optimization formulations, analysts are enabled to generate and evaluate various scenarios to identify their most effective solution completely satisfying customer needs tailored to objectives and constraints  that might exist within their environment.

The presentation aims to demonstrate selected applications of using data from the ULSAB project. The goal of the ULSAB program at that time (project ended in 1998) was to develop a light-weight body structure design (BIW) that was predominantly made of steel. Meanwhile Multi-Material-Concepts or purely FRP (Fiber Reinforced Plastics) were discussed and have been introduced. While it is understood that every automobile manufacturer has its own structure for estimating vehicle cost, the ULSAB project still provides valuable data to compile a transparent and reliable cost analysis.
