[ 5 ] - ارزیابی کارایی سود در زنجیره تامین سه مرحله ای با خروجی های برگشت داده شده با تکنیک تحلیل پوششی داده ها
مدیریت زنجیره تامین برای مدیران سازمان های مختلف به منظور بهبود عملکرد آن سیستم ها یک امر حائز اهمیت است. از جمله موارد این مدیریت آنالیز، تحلیل، و بررسی هر یک از مراحل یک زنجیره تامین می باشد. ارزیابی یک زنجیره به صورت "جعبه سیاه" به منظور مدیریت آن نمی تواند اطلاعات دقیقی برای تعیین استراتژی و هدف گزاری ارایه دهد. لذا لزوم به استفاده از تکنولوژی‌ها و ابزارهای جدید جهت تحلیل کل زنجیره و هر ...
[ 6 ] - MULTI-OBJECTIVE LOCATION-ROUTING MODEL WITH MULTIPLE TRANSPORTATION MODES FOR DESIGNING RELIEF NETWORKS UNDER UNCERTAINTY
Natural disasters and crisis are inevitable and each year impose destructive effects on human as injuries and damage to property. In natural disasters and after the outbreak of the crisis, demand for logistical goods and services increase. Effective distribution of emergency aid could have a significant role in minimizing the damage and fatal accident. In this study, a three-level relief chain...
[ 7 ] - Optimization of solution stiff differential equations using MHAM and RSK methods
In this paper, a nonlinear stiff differential equation is solved by using the Rosenbrock iterative method, modified homotpy analysis method and power series method. The approximate solution of this equation is calculated in the form of series which its components are computed by applying a recursive relations. Some numerical examples are studied to demonstrate the accuracy of the presented meth...
[ 8 ] - Improving adaptive resolution of analog to digital converters using least squares mean method
This paper presents an adaptive digital resolution improvement method for extrapolating and recursive analog-to-digital converters (ADCs). The presented adaptively enhanced ADC (AE-ADC) digitally estimates the digital equivalent of the input signal by utilizing an adaptive digital filter (ADF). The least mean squares (LMS) algorithm also determines the coefficients of the ADF block. In this sch...
