A general branch-and-bound framework for continuous global multiobjective optimization

Eichfelder, Gabriele; Kirst, Peter; Meng, Laura; Stein, … - In: Journal of Global Optimization 80 (2021) 1, pp. 195-227

Current generalizations of the central ideas of single-objective branch-and-bound to the multiobjective setting do not seem to follow their train of thought all the way. The present paper complements the various suggestions for generalizations of partial lower bounds and of overall upper bounds...

A note on completely positive relaxations of quadratic problems in a multiobjective framework

Eichfelder, Gabriele; Groetzner, Patrick - In: Journal of Global Optimization 82 (2021) 3, pp. 615-626

In a single-objective setting, nonconvex quadratic problems can equivalently be reformulated as convex problems over the cone of completely positive matrices. In small dimensions this cone equals the cone of matrices which are entrywise nonnegative and positive semidefinite, so the convex...

Adequacy Assessment of Time of Dispatch Rules using Fuzzy TOPSIS Method

Alibeigi, Ali; Asemi, Adeleh; Munir, Abu Bakar; … - 2021

Adequacy assessment of the existing Time of Dispatch (TD) rules is an academic primary step to improve the regulation of electronic commerce laws. This study aims to evaluate the ASEAN countries based on the adequacy of their TD rules. We propose an extended Fuzzy Technique for Order Preference...

Evaluating ASEAN E-Commerce Laws Using Fuzzy Multi-Criteria Decision Making

Alibeigi, Ali; Asemi, Adeleh; Munir, Abu Bakar; Baba, … - 2021

An evaluation of the ASEAN Electronic Commerce Acts (ECAs) is a specific primary step toward their harmonization. This evaluation is complex due to multiple criteria and uncertain information, especially in the case of electronic contracts. This study aims to evaluate and rank the ECAs of the...

Upgrading Current Multi-Attribute Decision-Making with a 3-Dimensional Decision Matrix for Future-Based Decisions

Sorooshian, Shahryar - 2021

Two shortcomings of existing Multi-Attribute Decision-Making (MADM) approaches are presented in this paper. The problems were decision makers' (experts') dynamic level of experience in certain areas, as well as the difficulties of forecasting the future with the existing MADM techniques. A...

Add or Multiply? A Tutorial on Ranking and Choosing with Multiple Criteria

Tofallis, Chris - 2021

Simple additive weighting is a well-known method for scoring and ranking alternative options based on multiple attributes. However, the pitfalls associated with this approach are not widely appreciated. For example, the apparently innocuous step of normalizing the various attribute data in order...

Explainable Interactive Evolutionary Multiobjective Optimization

Corrente, Salvatore; Greco, Salvatore; Matarazzo, Benedetto - 2021

We present a new interactive procedure for evolutionary multiobjective optimization involving the decision rule … preference model in the search for the best compromise solution. As usual in the interactive multiobjective optimization … elicitation phase falls into many iterations of the evolutionary multiobjective optimization. In the preference elicitation phase …

Modelling Best-Practice Frontiers when there are Multiple Outputs

Tofallis, Chris - 2021

This paper presents a way of modelling relationships between multiple dependent and multiple independent variables. The method involves fitting coefficients to functions of these two sets of variables such that the resulting ‘aggregate’ functions have maximum correlation. The inclusion of...
