چکیده

مرحله‌ی تبدیل اولیه چوب ‌آلات شامل فرآیند اره‌کردن، یکی از مهم‌ترین شاخص‌های مهم برای ارزیابی راندمان بنگاه-های تولید چوب است. در صنعت امروزی چوب ایران، گونه‌ی صنوبر نقش مهمی در تأمین ماده‌ی اولیه داشته و افزایش راندمان ‌در کارگاه ‌های چوب ‌بری با بهینه‌ سازی عوامل مؤثر بر روی گونه‌ی چوبی، ماشین و اپراتورها ضروری به نظر می‌رسد. استان اردبیل مخصوصاً شهر خلخال یکی از مراکز مهم تولید چوب صنوبر می ‌باشد. در این شهر تعداد زیادی کارگاه‌ های کوچک و بزرگ در صنعت چوب‌بری فعال هستند که در این کار پژوهشی تعداد 60 کارگاه جهت مطالعه انتخاب شدند. در این بررسی توصیفی، تحلیل پیمایشی راندمان گرده‌‌های صنوبر بر مبنای واحد‌ها تحلیل، با نرم افزار SPSS صورت می‌گیرد. از این‌رو آزمون فریدمن به منظور رتبه‌بندی شاخص‌های مؤثر در راندمان گرده‌‌های صنوبر در کارگاه‌های منتخب چوب‌بری منطقه خلخال استفاده شد. طبق نتایج بدست آمده، نیروی انسانی با میانگین رتبه 05/4 مهم‌ترین، پس از آن کیفیت چوب‌آلات با میانگین رتبه 93/3 در رتبه دوم، مدیریت با میانگین رتبه 87/2 در رتبه سوم، کیفیت گرده‌ها با میانگین رتبه 62/2 در رتبه چهارم و نهایتاً کیفیت ماشین‌آلات با میانگین رتبه 53/1 در رتبه آخر قرار گرفت. همچنین آزمون کای‌دو نشان داد، آموزش نیروی انسانی در راندمان گرده‌های صنوبر در کارگاه‌های چوب‌بری بسیار با اهمیت است. راندمان تولید چوب آلات تقریبا برابر 71 درصد می‌باشد که نشان‌دهنده توجه به این شاخص‌ها در کارگاه‌های چوب‌بری می‌باشد.

چکیده [English]

The primary conversion of woodwork involves the sawing process is one of the most important indicators that applicating to evaluate the efficiency of wood processing companies. In today's Iranian wood industry, poplar species is play as important role in supplying primary material. Increasing efficiency with optimizing the important factors involves wooden species, machine and operators is necessary. The province of Ardebil, especially Khalkhal, is one of the important centers for poplar timber production. There are a large number of small and large workshops in the wood industry which 60 workshops were selected. In this descriptive study, survey analysis of effective indicators on the sawmills yields is based on the comparison of analysis with SPSS software units. For this purpose, Friedman test was used to rank the effective indices of sawmills in Khalkhal area. According to the results, the manpower with the average rating of 4.05 is the most important, after which the quality of timber with an average rating of 3.93 in the second rank, management with an average rating of 2.87 in the third rank, the quality of log with the average rating of 2.62 was in fourth place and finally the quality of machinery with the average rating was 1.53 in the last rank. Also, Chi-square test showed that training of manpower on the sawmills efficiency of poplar logs in workshops is very important. Efficiency of poplar sawmills is equal 71% that resulted the consideration important indicators.
