Multilevel Optimization for Enterprise Driven Decision-Based Product Design

Abstract: Research in Decision-Based Design (DBD) has traditionally modeled the interaction between enterprise product planning and engineering product development in a single optimization problem and solved it using an All-in-One (AIO) approach. Such an approach is not practical in a typical industry design environment, due to the organizational and computational complexities involved. In this paper, we present a hierarchical multilevel optimization approach, based on the principles of DBD and the concept of analytical… Show more

“…A hypothetical vehicle market is used to describe this procedure. The MSG consists of four market segments along the horizontal axis (corresponding to sports, family sedan, SUV, and luxury segments) and three performance/cost tiers on the vertical axis, leading to twelve niches in all (see Figure (Wassenaar et al, 2006, Kim et al, Kumar et al, 2006, Wassenaar and Chen, 2003). The demand model used in this work, establishes the relationship between the customer desired attributes, A, the socioeconomic and demographic attributes, S, price, P, and the demand, Q, i.e., Q(A, S, P).…”

“…As a result, several multidisciplinary design optimization (MDO) techniques such as all-at-once (AAO), individual-discipline feasible (IDF), and multi-discipline feasible (MDF) approaches were developed [4,5]. Since then, other MDO solution methods including collaborative optimization (CO), concurrent subspace optimization (CSSO), and bi-level integrated system synthesis (BLISS) have been created and demonstrated in example problems [6]. MDO techniques apply various decomposition and coordination methods to facilitate communication between several disciplines while utilizing common optimization solvers to find a solution.…”
