Most multicriteria methods focus on ranking and selecting from a set of alternatives. These methods are usually used to compare all alternatives based on the synthesized scorings within a normalized scale with respect to the same criteria in multicriteria problems. However, the decision makers often simultaneously manage one or several alternatives/projects with conflicting and noncommensurable criteria to reduce the gaps to achieve the aspired grade in practice. They then need to rank the gaps that have not been reduced or improved (the unimproved gaps) for the alternatives/projects or aspects of a project to get the most benefit. Because these compared alternatives/projects do not usually have the same criteria/aspects, traditional methods are unsuitable to deal with them. Thus, this research proposes a new VIKOR method to solve this problem; this new method allows the decision maker to understand these gaps of the projects/aspects and rank them to improve these large gaps in control items to achieve the aspired level. Its concept originates in compromise solutions, in particular the VIKOR method. In addition, this research also provides an example of improving information security risk to demonstrate the suitability of this new method. The results show the effectiveness of the new method.

A company's core competitiveness depends on the strategic allocation of its human resources in alignment with employee capabilities. Competency models can identify the range of capabilities at a company's disposal, and this information can be used to develop internal or external education training policies for sustainable development. Such models can ensure the importation of a strategic orientation reflecting the growth of its employee competence set and enhancing human resource sustainably. This approach ensures that the most appropriate people are assigned to the most appropriate positions. In this study, we proposed a new hybrid multiple attributed decision-making model by using the Decision-making trial and Evaluation Laboratory Technique (DEMATEL) to construct an influential network relation map (INRM) and determined the influential weights by using the basic concept of the analytic network process (called DEMATEL-based ANP, DANP); the influential weights were then adopted with a modified Vise Kriterijumska Optimizacija I Kompromisno Resenje (VIKOR) method. A simple forecasting technique as an iteration function was also proposed. The proposed model was effective. We expect that the proposed model can facilitate making timely revisions, reflecting the growth of employee competence sets, reducing the performance gap toward the aspiration level, and ensuring the sustainability of a company.
