Design problem exploration
<p>The problem generation space is a critical stage in the design process that reflects the outcome of a solution. However, limited research has been conducted on problem space within design education to aid in the creative process. Within the problem generation space, there are multiple …

A multi-attribute layout design problem
… or the qualitative attribute of the layout problem. These procedures are based on maximizing or minimizing one objective function. Some of the procedures that address the multi-attribute nature of the plant layout problem are based on assigning weights to objective functions and then solving …

Accessing networked services : a user interface design problem
… research investigates the general user interface problems in using networked services. Some of the problems are: users have to recall machine names and procedures to. invoke networked services; interactions with some of the services are by means of menu-based interfaces which are quite cumbersome …

Design problem optimization with multi-objective evolutionary algorithms
Complex design challenges involve conflicting objectives and require robust optimization techniques. They commonly arise in engineering, building design, robotics, drug design, and energy systems, among others, where balancing competing criteria is essential. Sunshade optimization is also a complex …

CONFIDENCE REGIONS FOR OPTIMAL CONTROLLABLE VARIABLES FOR THE ROBUST PARAMETER DESIGN PROBLEM
In robust parameter design it is often possible to set the levels of the controllable factors to produce a zero gradient for the transmission of variability from the noise variables. If the number of control variables is greater than the number of noise variables, a continuum of zero-gradient …

Using Case Comparison to Support the Development of Instructional Design Problem-Solving Strategies
A popular instructional approach for developing problem-solving abilities is case-based instruction (CBI). One limitation of CBI is that problem solvers, especially novices, often fail to recall relevant cases from memory when needed. Analogical encoding is a promising approach to CBI for …

Global Optimization of the Nonconvex Containership Design Problem Using the Reformulation-Linearization Technique
The containership design problem involves optimizing a nonconvex objective function over a design space that is restricted by a set of constraints defined in terms of nonconvex functions. An application of standard nonlinear optimization methods to such a problem can at best attain a local optimum …

A structured reduced sequential quadratic programming and its application to a shape design problem
… work is to solve a model one dimensional duct design problem using a particular optimization method. The design problem is formulated as an equality constrained optimization, called All at once method, so that the analysis problem is not solved until the optimal design is reached. Furthermore, …

Performance optimization study of a Common Aero Vehicle using a Legendre Pseudospectral Method
The problem of performance optimization of a Common Aero Vehicle (CAV) is considered. In particular, the CAV is modeled as an unpowered high lift-to-drag ratio Earth penetrating re-entry vehicle. The CAV mission design problem is to determine a steering command that takes the CAV from a known …
