“…Looking at studies from different application fields in the literature (e.g., References [21][22][23][24][25][26][27]), the goal programming method allows decision-makers to simultaneously realize different goals [28,29]. The most important features that distinguish constraint programming from mathematical programming include mathematical constraints or constraints that can be of a logical or symbolic type [30][31][32]. The integrated goal programming and constraint programming methods, which are used in the solution process, are effective solution tools for researchers.…”

The achievement of health organizations’ goals is critically important for profitability. For this purpose, their resources, materials, and equipment should be efficiently used in the services they provide. A hospital has sensitive and expensive equipment, and the use of its equipment and resources needs to be balanced. The utilization of these resources should be considered in its operating rooms, as it shares both expense expenditure and revenue generation. This study’s primary aim is the effective and balanced use of equipment and resources in hospital operating rooms. In this context, datasets from a state hospital were used via the goal programming and constraint programming methods. According to the wishes of hospital managers, three scenarios were separately modeled in both methods. According to the obtained results, schedules were compared and analyzed according to the current situation. The hospital-planning approach was positively affected, and goals such as minimization cost, staff and patient satisfaction, prevention over time, and less use were achieved.

In simple assembly line balancing problems, it is assumed that the resources required to perform the tasks are available at the relevant station for task assignment. However, each task may need different resource types depending on the difficulty, complexity and technical requirements of the tasks in real life. For this reason, tasks and resources belonging to these tasks must be assigned to the relevant station while balancing the line. In this study, the resource-constrained U-shaped assembly line balancing problem(U-GRCALBP) is discussed. According to the literature research, there is no study dealing with U-GRCALBP. Two different constraint programming (CP) models that define the resource constraints as "and/or" constraint types with concurrent resource types have been developed. In these models, the sum of resource usage costs and station opening cost minimization is aimed. The models are explained with an illustrative example and the efficiency of the models was tested by deriving new resource constraints on sample data sets. The number of stations obtained, the total number of resources used, total station opening and resource usage costs, and CPU time were used as performance criteria. According to the numerical results, it has been shown that both models are effective in solving the problem.
