The producing of nanofiber tissue scaffolds is quite important for enhancing success in tissue engineering. Electrospinning method is used frequently to produce of these scaffolds. In this study, a simple and novel expression derived by using artificial bee colony (ABC) optimization algorithm is presented to calculate the average fiber diameter (AFD) of the electrospun gelatin/bioactive glass (Gt/BG) scaffold. The diameter of the fiber produced by electrospinning technique depends on the various parameters like process, solution, and environmental parameters. The experimental results previously published in the literature, which include one solution parameter (BG content) as well as two process parameters (tip to collector distance and solution flow rate) related to producing of electrospun Gt/BG nanofiber, have been used for the optimization process. At first, the AFD expression has been constructed with the use of the solution and process parameters, and then the unknown coefficients belonging to this expression have been accurately determined by using the ABC algorithm. From 19 experimental data, 15 ones are used for the optimization phase while the other 4 data are utilized in the verification phase. The values of average percentage error between the calculated average fiber diameters and experimental ones are achieved as 2.2 % and 5.7 % for the optimization and verification phases, respectively. The results obtained from the proposed expression have also been confirmed by comparing with those of AFD expression reported elsewhere. It is illustrated that the AFD of electrospun Gt/BG can be accurately calculated by the expression proposed here without requiring any complicated or sophisticated knowledge of the mathematical and physical background.
