چکیده مقاله :

در این تحقیق مدل جدیدی برای ارزیابی سیاست‌های ظرفیتی براساس سفارشات جدید محصولات، موجودی مالی و بودجه بر اساس سیستم های پویا ارائه شده است. قلمرو تحقیق شرکت ملی گاز ایران می باشد. داده‌های به دست آمده از طریق مصاحبه‌های اکتشافی از کارشناسان شرکت ملی گاز ایران انتخاب شد.در ابتدا بر اساس ارزیابی مطالعات نظری، مصاحبه‌های اکتشافی با خبرگان و توسعه چارچوب مفهومی پژوهش انجام شده و پس از بررسی اطلاعات مربوط به رفتار متغیرها، ارتباطات منطقی از نحوه تاثیرگذاری آنها بر روی یکدیگر استخراج شده و پس از بیان فرضیه پویایی، نموار علت معلولی مربوط تهیه شد. پس از ترسیم نمودار حلقه‌های علی و معلولی و به منظور آنالیز و تحلیل پارامترهای دخیل در مدل، نمودار انباشت جریان رسم گردید. مدل طراحی شده اجرا شده و رفتار متغیرها بررسی و سپس اعتبارسنجی مدل انجام شد.مدل شامل چهار بخش سفارشات ، تولید ، تحقیق و توسعه ظرفیت سازی و بخش مالی می باشد.پس از اجرای برنامه ارتباط و تاثیر پارامترها بر یکدیگر مشخص گردید . نتایج نشان داد که شرکت ظرفیت تولید و سطح موجودی خود را با در نظر گرفتن نرخ سفارش دریافتی از سوی مشتریان تنظیم می‌نماید و خروجی محصول خود را با نگرش عدم خروجی قابل ذخیره در نظر گرفت و همانطور که در مدل مشاهده نمودید با این رویکرد توانست تا ظرفیت تولید و سطح موجودی را با نیاز بازار تطابق بخشد.

چکیده انگلیسی:

. In this research, a new model for evaluating capacity policies based on new product orders, financial inventory and budget based on dynamic systems is presented. The scope of research is the National Iranian Gas Company. The data obtained through exploratory interviews were selected from the experts of the National Iranian Gas Company. Their effects on each other were extracted and after expressing the dynamics hypothesis, a sample of the related cause-effect was prepared. After plotting the causal loops and in order to analyze the parameters involved in the model, the flow accumulation diagram was drawn. The designed model was implemented and the behavior of the variables was investigated and then the model was validated. The model includes four sections: orders, production, research and development of capacity building and the financial section. The results showed that the company adjusts its production capacity and inventory level by considering the order rate received from customers and considered the output of its product with the attitude of no stock output and as you saw in the model with this approach was able to Match production capacity and inventory level with market needs.
