We propose SonOpt, the first (open source) data sonification application for monitoring progress of bi-objective population-based optimization algorithms during search, to facilitate algorithm understanding. SonOpt provides insights into convergence/stagnation evolution approximation set shape, location recurring points in set, and population diversity. The benefits have been shown various non-...

although many scholars have proposed all kinds of key successful factors (ksfs) for erp activity to smoothly enhance the implementation of erp, the ksfs are based too much on concept and protocol cannot help an enterprise to achieve this objective. therefore, this research through qualitative interview method, integrating the ksfs and dynamic capability to set up a model so as to exhibit the ki...

This article deals with a bi-objective matching problem. The input is a complete graph and two values on each edge (a weight and a length) which satisfy the triangle inequality. It is unlikely that every instance admits a matching with maximum weight and maximum length at the same time. Therefore, we look for a compromise solution, i.e. a matching that simultaneously approximates the best weigh...

The paper discusses the definition and solution of a bi-objective routing problem, namely the bi-objective covering tour problem. The bi-objective CTP is a generalization of the covering tour problem, which means that the covering distance and the associated constraints have been replaced by a new objective. We propose a two-phase cooperative strategy that combines a multi-objective evolutionar...

In order to solve the two-sided matching problem based on uncertain score information, a new method is presented. Firstly, the description of the two-sided matching problem with uncertain scores is given. Secondly, the satisfaction degrees of each agent towards the agents on the other side are calculated. A multi-objective optimization model to maximize the satisfaction degrees of agents is set...

This paper presents a novel bi-objective multi-product capacitated vehicle routing problem with uncertainty in demand of retailers and volume of products (UCVRP) and heterogeneous vehicle fleets. The first of two conflict fuzzy objective functions is to minimize the cost of the used vehicles, fuel consumption for full loaded vehicles and shortage of products. The second ...

Ecological sustainability has become a top priority for governments and business practitioners because of the massive surge in electronic waste (e-waste). This ecological context compelled firms to adopt reverse logistics (RL) invest advanced technologies with focus on sustainable recovery practices reducing excessive carbon emissions (CEs). study proposes multi-objective mixed integer programm...
