Nurse rostering using fuzzy logic: A case study

In this paper, we used the fuzzy set theory for modeling flexible constraints and uncertain data in nursescheduling problems and proposed a fuzzy linear model for nurse rostering problems. the developed modelcan produce rosters that satisfy hospital objectives, ward requirements and staff preferences by satisfying theirrequests as much as possible. fuzzy sets are used for modeling demands of personnel in each shift. the objectiveis to identify the optimum roster for nurses in order to complete the weekly roster with fuzzy constraints.this model is implemented for the data collected from namazi hospital (nh) of shiraz, which is the largesthospital in south of iran. after modeling, this problem is solved by using lingo software. finally we comparethe result of fuzzy rosters with goal programming rosters that we have previously modeled and with manualrosters that are produced by the head nurses of nh.
