@ARTICLE{Jafari, author = {Jafari, H. and }, title = {Developing a Fuzzy Model for the Nurse Scheduling Problem}, volume = {17}, number = {2}, abstract ={Recently, the nurse scheduling problem has attracted considerable attention in different areas. In this problem, the number of the required nurses for the daily shifts has been given during the planning horizon and the objective is assigning the shifts to the nurses in order to meet the required demands. In this paper, first, a mathematical programming model is presented to maximize the nurses’ preferences for the working shifts. Then, to investigate the uncertainty on the nurses’ preferences, a fuzzy modeling approach based on the Werner’s fuzzy operator is proposed for the research problem. Finally, to evaluate the proposed fuzzy model, several random test problems are generated and solved using the fuzzy model. Moreover, a sensitivity analysis is implemented to investigate the effects of the changes of the parameters on the obtained results. Regarding the results, high quality schedules can be generated by the proposed fuzzy model. }, URL = {http://jamlu.liau.ac.ir/article-1-1650-en.html}, eprint = {http://jamlu.liau.ac.ir/article-1-1650-en.pdf}, journal = {Journal of Operational Research and Its Applications}, doi = {}, year = {2020} }
