| چکیده | ||
| در این مطالعه، به‌منظور تعیین مکانیزاسیون بهینۀ حملونقل اولیه چوب در جنگل های هیرکانی ایران، ماشین‌های فعلی شامل Timberjack 450C، HSM 904، تراکتور کشاورزی و برخی ماشین‌های جدید شامل LKT 81، TAF 690، Vimek 610 و Mowi 650 مورد بررسی قرار گرفتند. از روش برنامه ریزی آرمانی که روشی برای بهینه سازی چند هدف، شامل: زیست محیطی، اقتصادی، عملکرد، ارگونومیک است، استفاده شد. نتایج بررسی های اقتصادی نشان میدهد که در حال حاضر برای حمل گرده بینه، اسکیدرهای Timberjack 450C و HSM 904 نسبت به ماشین‌های دیگر هزینه حمل و نقل کمتری دارند و به لحاظ اقتصادی همچنان ماشین‌های مقرون به‌صرفه‌ای هستند. استفاده از تراکتور کشاورزی برای حمل هیزم و کاتین مقرون به‌صرفه نیست و گزینه اقتصادی جایگزین، تریلر Mowi 650 است. با این جایگزینی، هزینه حمل هیزم و کاتین 44 درصد کاهش می‌یابد. نتایج بهینه‌سازی با استفاده از برنامه‌ریزی آرمانی و لحاظ کردن همه هدف ها نشان می دهد که برای حمل گرده بینه و هیزم، اسکیدر LKT 81 و فورواردر Vimek 610 باید جایگزین ماشین های فعلی شود. با این جایگزینی، هزینه حمل برای گرده بینه 15 درصد افزایش و برای هیزم و کاتین 10 درصد کاهش می‌یابد. در حال حاضر مکانیزاسیون حملونقل اولیه چوب در جنگلهای هیرکانی از لحاظ هدفهای چهارگانه این مطالعه، بهینه نیست و نیاز به تغییر دارد. در مدیریت ماشین آلات جنگل، جنبه‌های زیست‌محیطی و ارگونومیک باید مورد توجه قرار گیرد. | ||

| چکیده [English] | ||
| In this study, in order to determine the optimal mechanization of the wood primary transportation in the Hyrcanian forests of Iran, current machines including Timberjack 450C, HSM 904 and agricultural tractor and number of new machines including LKT 81, TAF 690, Vimek 610 and Mowi 650 were investigated. The Goal Programming technique, a multi-objective optimization method, including environmental, economic, performance, ergonomics, was used. The results showed that Timberjack 450C and HSM 904 skidders had less log transporting costs compared to other machines, and economically are still cost-effectively machines. For the transporting of firewood, Farm tractor is not cost-effectively and the alternative economic option is Mowi 650 trailer. In the case of replacement, the cost of firewood transporting will decrease by 44%. Optimization results, using goal programming regarding all the goals, have shown that existing machines should be replaced by the LKT 81 skidder and the Vimek 610 forwarder to transport logs and firewoods, respectivlly. With the replacement, the costs of log transporting will increase to 15% and the costs of firewood transporting will decrease to 10%. Currently, the mechanization of wood transportation in Hyrcanian forests is not optimal in terms of quadratic goals and needs to be changed. In the forest machinery management, the environmental and ergonomic aspects should be taken into consideration. | ||
