The Analytical Hierarchy Process (AHP) is one of the multi-criteria methods with tools that are effective for decision-making in complementary or alternative medicine (CAM). This approach, in combination with other available methods, such as the Utrecht Method, allows medical professionals and patients themselves to take a balanced choice of special treatment and health control. This is particularly important for pregnant women who suffer from nausea and vomiting during pregnancy (NVP). The mechanisms of toxicosis occur, and the way of treatment have certain uncertainties. The decision-making process for therapeutic care must consider several factors, the determination of which is the result of collaboration between the patient and the healthcare provider. This paper presents the results of a decision-making study regarding the use of the ginger medicinal plant in helping a woman with NVP symptoms. The research was conducted using the original questionnaire according to the methodology proposed by the developers of the Utrecht Method. The chosen respondents were healthcare professionals with experience in treating NVP and pregnant women. The Analytical Hierarchy Process (AHP) capabilities in decisionmaking were shown in an example of analyzing the benefits, risks, and side effects of using ginger during pregnancy. The combination of two methodological approaches allowed to successfully connect the proven facts of using CAM therapy with the subjective assessment of all stakeholders. The study demonstrates that this approach successfully uses decision-making by structuring hierarchical decision elements and weighing the criteria involved in the decision-making issue. The article examines the practicality and effectiveness of using AHP when making decisions regarding the treatment and improvement of the condition of pregnant women with NVP, and summarizes the quantitative and qualitative indicators of the effectiveness of this method. The presented combination of two methodological approaches in decision-making allows for choosing an optimized medical strategy for supporting pregnant women through CAM therapy.

A large portion of the credits and financial resources of countries is spent on the preparation and construction of building projects because their implementation would create housing, job opportunities, financial turnover, and economic prosperity. At present, many construction projects are under construction in developing countries, and most of these projects are facing rising costs. The local scope of this research is construction projects in Yazd city. This research is operational in terms of purpose and was carried out in a descriptive and survey manner with an analytical-mathematical method. Data collection was done by documentary and survey methods. The Statistical Society consisted of 150 managers and officials, contractors, and actors involved in construction projects. Data analysis by hierarchical analysis technique showed that the criterion of management factors with a weight of 0.582 has the highest priority in increasing building costs. The criterion of environmental factors with a weight of 0.309 is at the second priority. The criterion of legal and administrative factors with a weight of 0.109 is in the third priority. Therefore, a key element in increasing the cost of construction projects in the under-studied city is the management factor that can be reduced by establishing new management systems and improving the quality of construction projects.

Jednym z podstawowych zadań, przed jakimi staje kierownik projektu, jest podejmowanie decyzji dotyczących sposobu realizacji i (ewentualnego) wyboru podwykonawców projektu. Zjawiska analizowane na poszczególnych etapach cyklu życia projektu są bardzo złożone, co wynika z rosnącej liczby analizowanych obiektów oraz złożoności występujących między nimi relacji. Niniejszy artykuł, wprowadzający do praktycznego stosowania metody analizy hierarchicznej, prezentuje możliwości jej zastosowania w procesie wyboru podwykonawców projektu.

One of the principal tasks of a project manager is to take decisions concerning how the project is to be executed, and to select subcontractors where required. The phenomena analysed at particular stages of the project lifecycle are very complex, due to the increasing number of analysed structures and the complexity of the relations between them. This paper, which serves as an introduction to the practical application of the hierarchical analysis method, presents possibilities for the application of that method in the process of selection of subcontractors for a project.

W niniejszym artykule scharakteryzowano metody służące do rozwiązywania problemów wielokryterialnych. Opisano także wybrane metody oceny wpływu budynków na środowisko oraz wagi przyjęte w tych systemach. Z przedstawionego przykładu widać, że istnieje rozbieżność w przyporządkowywaniu wag emisji otrzymywanych na podstawie kosztów emisji i wg metody analizy hierarchicznej.

This paper presents the methods for solving multicriteria problems, methods of assessment for building environment efficiency and the weights for these systems. The example shows that there is a discrepancy in attributing emissions weights based on the cost issue and according to the method of analytical hierarchy process.
