Plastic injection moulding process produces various defects such as warpage, sink marks, weld lines and shrinkage. The purpose of present paper is to analyze the warpage defect on Acrylonitrile Butadiene Styrene (ABS) for selected part using FEA simulation. The approach was based on Taguchi’s Method and Analysis of Variance (ANOVA) to optimize the(More)
— Shorter product life cycle, variable demands and international competitions become challenging issues nowadays hence, most of manufacturer made attempts to select type of manufacturing system for their company which be able to respond to these issues. Group technology [GT] is one of the most recent manufacturing philosophies which is able to cover the(More)
Sex steroid hormones, including androgens and estrogens, have a wide array of cellular effects. Traditionally, steroid hormones have been considered slow acting, a consequence of mechanisms through which the expression of various genes are altered due to steroids binding to receptors that interact with the DNA. Genomic mechanisms thus typically affect(More)

Scheduling occurs in every organization without considering the nature of its activities. In this regard, numerous scholars have attempted to schedule via divergent methods including classical scheduling, genetic algorithm, neural network and fuzzy logic and so on. Studies in manufacturing scheduling mostly deal with priority rules without any consideration(More)
