“…GP modelling is also another MP approach that deals with multiple explicit goals in the decision context and allows the decision-maker to consider these goals simultaneously [38]. Thus, it is now a key approach in the multi-objective programing (MOP) field [39][40][41][42][43]. In addition, it is also a flexible decision analysis tool when the problem involves conflicting goals subject to a number of complex decision constraints [44][45][46].…”

The administration of A/B exams usually involves the use of items. Issues arise when the pre-establishment of a question bank is necessary and the inconsistency in the knowledge points to be tested (in the two exams) reduces the exams ‘fairness’. These are critical for a large multi-teacher course wherein the teachers are changed such that the course and examination content are altered every few years. However, a fair test with randomly participating students should still be a guaranteed subject with no item pool. Through data-driven decision-making, this study collected data related to a term test for a compulsory general course for empirical assessments, pre-processed the data and used item response theory to statistically estimate the difficulty, discrimination and lower asymptotic for each item in the two exam papers. Binary goal programing was finally used to analyze and balance the fairness of A/B exams without an item pool. As a result, pairs of associated questions in the two exam papers were optimized in terms of their overall balance in three dimensions (as the goals) through the paired exchanges of items. These exam papers guarantee their consistency (in the tested knowledge points) and also ensure the fairness of the term test (a key psychological factor that motivates continued studies). Such an application is novel as the teacher(s) did not have a pre-set question bank and could formulate the fairest strategy for the A/B exam papers. The model can be employed to address similar teaching practice issues.

Companies have to make the right investment moves at the right time in order to sustain their existence and growth. For this reason, it is a critical decision for companies to distribute the existing capital to which projects and to what extent. Investment alternatives can be classified into two groups as dependent and independent. In dependent investment projects, the decision of whether to invest in a project directly affects the investment decision of the other project. In independent projects, it is necessary to consider the budget constraint in accordance with the reality of life. No matter how big the companies mentioned are, it is impossible to talk about an endless source of investment. For this reason, present value analysis, which is one of the most common methods used when evaluating independent project investments, is discussed under intuitionistic fuzziness in this study. It is aimed to achieve the most realistic results by reflecting the ambiguity and vagueness in the thoughts of the decision makers. In addition, this study demonstrates the integrability of fuzzy sets into engineering economics analysis methods. With this study, the cash flow data has been fuzzified and alternatives with both equal and different expected lives have been formulated to provide maximum returns under a certain budget limit. In addition, the responses of different parameters to changes were measured with intuitionistic fuzzy sensitivity analysis.
