Production planning includes complex topics of production and operation management that according to expansion of decision-making methods, have been considerably developed. Nowadays, Managers use innovative approaches to solving problems of production planning. Given that the production plan is a type of prediction, models should be such that the slightest deviation from their reality. In this ...

Echinacea purpurea belongs to the family of Asteraceae which has different medicinal properties. The main goal of current research was optimization of callus induction and biomass production by using Response Surface Method (RSM). For this purpose, root and leaf explants were cultured in the ½ MS medium supplemented with different concentrations (0, 1 and 2 mg/L) of Kin either alone or with 2,4...
