Abstract :
در این مقاله یک روش عددی جدید برگرفته از روش هممحلی، برای حل عددی مسایل مقدار اولیه سخت و معادلات انتگرال فردهلم نوع اول مبتنی بر مشتقات تابع مانده ارایه شده است؛ سپس تحلیل خطای این روش عددی با ارایه کران بالا برای خطا مورد بررسی قرار میگیرد. کارایی این روش با ارایه چندین مثال عددی از مسایل سخت و بدوضع با کارایی روش هممحلی مقایسه میشود. نتایج عددی بدست آمده نشان میدهد که روش ارایه شده در جایی که روش هممحلی برای حل عددی این نوع مسایل با شکست مواجه میشود از کارایی بالایی برخوردار است.
