چکیده مقاله :

چکیده تامین مالی همواره یکی از چالش‌های اصلی ایجاد و توسعه کسب‌و‌کارهای نوپا و صنایع کوچک اقتصادی بوده است. لذا هدف از پژوهش حاضر شناسایی و ارائه مدلی برای تأمین مالی صنایع کوچک و متوسط با رویکرد آزمایشگاه ارزیابی و آزمون تصمیم گیری بر پایه فرآیند مدل سازی ساختاری تفسیری و دیمتل فازی می باشد. مقاله حاضر به طراحی سناریوهای مختلف در تأمین مالی بنگاه های کوچک و متوسط پرداخته است. به همین جهت با توجه به مطالعات پیشین و روش غربال گری فازی به استخراج عوامل مؤثر بر تأمین مالی بنگاه های کوچک و متوسط و مشخص نمودن حلقه های علی - معلولی اقدام و مدل دینامیکی تدوین شده است. سپس با استفاده از تکنیک مدل سازی ساختاری و دیمتل فازی روابط و سطوح بین آنها میزان ضرایب تأثیرگذار و تأثیر پذیر مشخص و در مدل لحاظ شده است، در نهایت به منظور تست صحت مدل و مشخص شدن رفتار متغیرهای حالت و نرخ، اقدام به جمع آوری اطلاعات از 30 بنگاه کوچک و متوسط ، متقاضی شناخت روش های نوین تأمین مالی در بازه زمانی 12 ماهه شده است، که با تحلیل رفتار متغیرها در چهارچوب مدل همچنین تحلیل حساسیت، روایی الگوی دینامیکی طراحی شده مورد ارزیابی قرار گرفت. نتایج نشان داد، بنگاه های کوچک و متوسط از مدل و سناریوهای طراحی شده می توانند جهت تأمین مالی بهینه کسب و کار خود بهره مند گردند.

چکیده انگلیسی:

AbstractFinancing has always been one of the main challenges of creating and developing start-up businesses and small economic industries. Therefore, the purpose of the current research is to identify and present a model for financing small and medium industries with the approach of evaluation laboratory and decision test based on the process of interpretive structural modeling and Fuzzy Dimetal. This article deals with the design of different scenarios in the financing of small and medium enterprises. For this reason, taking into account the previous studies and the fuzzy screening method, a dynamic model has been developed to extract effective factors on the financing of small and medium enterprises and to specify the cause-effect circles. Then, using structural modeling technique and Fuzzy Demetall, relationships and levels between them, the amount of influential and influential coefficients have been determined and included in the model, finally, in order to test the accuracy of the model and determine the behavior of state and rate variables, we collected Information from 30 small and medium-sized enterprises has been requested to know the new methods of financing in a period of 12 months, which was evaluated by analyzing the behavior of the variables in the framework of the model, as well as the sensitivity analysis, and the validity of the designed dynamic model. The results showed that small and medium enterprises can benefit from the designed model and scenarios for optimal financing of their business.
