The weighted sum method for multi-objective optimization: new insights
TLDR
This paper investigates the fundamental significance of the weights in terms of preferences, the Pareto optimal set, and objective-function values and determines the factors that dictate which solution point results from a particular set of weights.Abstract:
As a common concept in multi-objective optimization, minimizing a weighted sum constitutes an independent method as well as a component of other methods. Consequently, insight into characteristics of the weighted sum method has far reaching implications. However, despite the many published applications for this method and the literature addressing its pitfalls with respect to depicting the Pareto optimal set, there is little comprehensive discussion concerning the conceptual significance of the weights and techniques for maximizing the effectiveness of the method with respect to a priori articulation of preferences. Thus, in this paper, we investigate the fundamental significance of the weights in terms of preferences, the Pareto optimal set, and objective-function values. We determine the factors that dictate which solution point results from a particular set of weights. Fundamental deficiencies are identified in terms of a priori articulation of preferences, and guidelines are provided to help avoid blind use of the method.read more

Impact of interest rates on forest management planning based on multi-criteria decision analysis
TL;DR: In this paper , the authors examined how different interest rates (0, 0.5, 1, 1.5%, 2, 2.5% and 3%) affect the fulfilment of multiple forest functions and hence, the decision on the optimal forest regeneration system for multiple criteria.

Optimized control mapping through user-tuned cost of effort, time, and reliability *
TL;DR: This work studies how the relative weights of individual cost functions in a composite movement cost affect the optimal control signal produced by the user and the mapping between the user’s control signals and the machine's output, using prosthesis control as a specific example.
