| چکیده | ||
| در این تحقیق، مصرف انرژی و انتشار آلایندههای زیستمحیطی تولید کلوچه در استان گیلان مورد بررسی قرار گرفت. دادههای لازم از طریق پرسشنامه و مصاحبه حضوری از 30 کارخانه تولید کلوچه جمعآوری شد. نتایج این پژوهش نشان داد که مقدار 50/30 مگاژول انرژی برای تولید هر کیلوگرم کلوچه مصرف شده است که بیشترین سهم انرژی مصرفی به گاز طبیعی با 09/17 مگاژول بر کیلوگرم اختصاص داشت. براساس نتایج ارزیابی چرخه زندگی، شاخص گرمایش جهانی برای تولید هر کیلوگرم کلوچه kg CO2 eq. 73/3 تعیین گردید که در حدود 51 درصد آن مربوط به احتراق گاز طبیعی جهت فرآیند پخت است. در نهایت، مدلسازی میزان عملکرد و اثرات زیستمحیطی براساس دو مدل شبکههای عصبی مصنوعی و سامانه استنتاج فازی- عصبی تطبیقی (انفیس) انجام شد. مقایسه نتایج نشان داد مدل انفیس چند لایه قادر است تا با دقت بیشتر و خطای کمتر عملکرد محصول را برآورد کند. | ||

| In this study, energy consumption and environmental emissions of cookie production in Guilan Province of Iran was investigated. The required information was collected using questionnaires and interviews from 30 factories of cookie production. Equivalent energies of inputs and outputs were calculated based on the standardized energy coefficients. The results of this study showed that 30.50 MJ of energy was consumed for production of one kilogram of cookie in which the highest share of energy consumption was allocated to natural gas with 17.09 MJ kg-1. Based on life cycle assessment (LCA) results, global warming (GW) index was calculated as 3.73 kg CO2 eq. per kilogram of produced cookie which about 51 percent of that was related to combustion of natural gas consumed in cooking process. Finally, the modeling of amount of yield and environmental impacts was conducted based on two models of artificial neural network (ANN) and adaptive neuro-fuzzy inference system (ANFIS). The results showed that ANFIS was capable of predicting yield with more accuracy and less error. | ||
