همه‌ساله در نقاط مختلف جهان شواهدی برای تائید خطای ناشی از عملکرد پردازش اطلاعات اپراتورها می‌باشد. هدف اصلی این مطالعه بررسی تقاضای نیروی انسانی اپراتورها براساس مدل پردازش اطلاعات انسانی و بارکاری، و تدوین یک مدل رگرسیونی برای آن بوده است. </span></p> <p style="margin-bottom: 0.0001pt text-align: justify line-height: normal background: none repeat scroll 0% 0% rgb(217, 217, 217) direction: rtl
