Ecological changes resulting from climate conditions can severely affect human societies especially in the area of economy and safety. Climate catastrophes may cause social and economic tension. Forecasting such changes ...

Uncertainties in industrial environments can cause considerable complexities, during the implementation and management of projects. So, performing a risk management model in such environments has become inevitable. In such ...

In recent years, reducing emissions has become an important issue. Besides reducing the economic costs, reducing the fuel consumption decreases emissions, pollutant impact and increases society health as well. Green vehicle ...

In this paper a new method is proposed for path planning of planar manipulators amid obstacles through mathematical programming in a way that the robot's links avoid collision with obstacles throughout their motion from ...

It is assumed in most of the existing models that the items can be stored for an unlimited time to meet the future's demand and their quality and quantity does not change during that period. Nevertheless there are special ...

In this paper, we consider a multi-site production planning problem subject to uncertainty in demand and workforce expenses. In our new mathematical model, we presented a production planning system considering failure in ...

In this study, we present a MRCPSP/max (Multi-mode Resource-Constrained Project Scheduling Problem with Minimum and Maximum time lags) model with minimization tardiness costs and maximization earliness rewards of activities ...

In this paper, a new approach of modeling for Artificial Neural Networks (ANN) models based on the concepts of ANN and fuzzy regression is proposed. For this purpose, we reformulated ANN model as a fuzzy nonlinear regression ...
