Abstract: Abstract: In order to solve the problem of keeping patients waiting too long in some hospitals, by use of reasonable system of evaluation based on Markov birth and death process and by aid of linear programming method under some restraint condition, a bed arrangement model I for minimal average hospital stay is desgned. The model has also worked out a rough time interval estimation concerning when ophthalmic patients are likely to be hospitalized. Considering the general practice of arranging no operations on Saturdays and Sundays and the relatively fixed proportion of hospital beds, due adjustment and evaluation is made to Model I. Finally, a hospital bed arragement Model II was constructed and bed allocation proportion was given in an effort to shorten patients’ average hospital stay.
