This paper puts forward an integrated fuzzy simulation-fuzzy data envelopment analysis (FSFDEA) algorithm
to cope with a special case of single-row facility layout problem (SRFLP). Discrete-event-simulation,
a powerful tool for analyzing complex and stochastic systems, is employed for modeling different
layout formations. Afterwards, a range-adjusted measure (RAM) is used as a data envelopment analysis
(DEA) model for ranking the simulation results and finding the optimal layout design. Due to ambiguousness
associated with the processing times, fuzzy sets theory is incorporated into the simulation model.
Since the results of simulation are in the form of possibility distributions, the DEA model is treated on
a fuzzy basis; therefore, a recent possibilistic programming approach is used to convert the fuzzy DEA
model to an equivalent crisp one. The proposed FSFDEA algorithm is capable of modeling and optimizing
small-sized SRFLP’s in stochastic, uncertain, and non-linear environments. The solution quality is
inspected through a real case study in a refrigerator manufacturing company
