Demand Forecasting for Seasonal Demand Patterns: Case Study of a Pharmaceutical Company
Abstract: In this paper the authors have developed a heuristic model that addresses demand forecasting for products those follow seasonal patterns. The model is checked against various renowned forecasting methods by comparing forecast errors. The proposed heuristic model is found to give better results than the Winters’ and other exponential models. Non-linear optimization is used to choose the values of smoothing parameters rather than depending on human judgment or experience. This …

Performance Evaluation of Vegetable Oil Based Cutting Fluids with Extreme Pressure Additive in Turning of AISI 1040 Steel
Abstract: Vegetable oils are being investigated as a potential source of environmental favorable lubricants, due to high biodegradability, renewability and good lubrication properties. The objective of this work is to determine the influence of vegetable oil based cutting fluids (sesame and coconut oil) with extreme pressure (EP) additive on machining performance in terms of cutting forces, cutting tool temperature, tool flank wear and surface roughness during turning of AISI 1040 steel …
