Increasing healthcare costs related to lifestyle-related chronic diseases require new solutions. Research on self-management tools is expanding and many new tools are emerging. Recording food intake is a key functionality in many of these tools. Nutrition monitoring is a relevant method to gain an overview of factors influencing health. However, keeping a food diary often constitutes a challenge for...
Hierarchical Heterogeneous Ant Colony Optimization (HHACO) was proposed previously to solve a combinatorial problem of healthy meal plans. Results of HACO are compared to the results obtained by the exact method. It is shown that the use of HACO is justified for the problems with greater size. Sensitivity analysis of HHACO was performed as well and the most influential model parameters were identified.
Ant Colony Optimization (ACO) is used to solve problems with multiple objectives. Various extensions have been implemented to the traditional approach to improve algorithm performance or quality of solutions. In this paper we propose a novel ACO-based method that involves heterogeneity and hierarchy in the area of automated meal plans. The hierarchy consists of 2 levels: at the first there are ants...
Modern system is complex and includes different types of components such as software, hardware, human factor. Reliability is principal property of this system. The importance analysis is one of approaches in reliability engineering. Application of this approach for healthcare system is considered in this paper. The importance reliability analysis allows estimating the influence of every healthcare...
