CNG vessels are used in many vehicles.  Mass production of CNG pressure vessels requires exact understanding of process effective parameters.  In this paper, the numerical analysis has been used to study the manufacturing parameters.  The entire manufacturing processes, including deep drawing, redrawing and ironing, of an aluminum liner sample of CNG pressure vessel (without spinning) have been...

an elliptical tank cross-section is formulated to explore and optimization method, based on a real-coded genetic algorithm to enhance the roll stability limit of a tank vehicle. a shape genetic algorithm optimization problem is applied to minimize the overturning moment imposed on the vehicle due to c.g. height of the liquid load, and lateral acceleration and cargo load shift . the minimization...

Electro Discharge Machining (EDM) is a very efficient machining process widely used in manufacturing components of complicated geometry. Based on its nature, i.e. material removal by electric discharge, the process induces thermal stresses that in turn result in generation of wide spread micro-cracks on the surface of the machined part. In this paper the influence of EDM characteristic paramete...

Additive manufacturing with electrohydrodynamic direct writing is a promising approach for the production of polymeric microscale objects. In this study we investigate the stability of one such process, melt electrospinning writing, to maintain accurate placement of the deposited fibre throughout the entire print. The influence of acceleration voltage and feeding pressure on the deposited poly(...

Today’s businesses continually search for ways to increase productivity. To achieve this goal, shorter product development cycles and shorter manufacturing times are required. In both cases, problems that may arise during development must be identified much faster. In product development, this is done using virtual prototypes that can be easily duplicated and shared between everyone involved. I...

Contemporary business process management technology has successfully been implemented to streamline and coordinate administrative business processes. The use of this type of technology to automate processes in complex manufacturing is however less mature. In this paper we discuss the research challenges and requirements for the application and extension of business process management concepts a...

In the modern world class manufacturing it is of prime importance for modern management to make crucial decisions quickly and accurately to stand at the global competitive cutting edge. In many real life situations the main interest concern the prediction of how a system will perform under various conditions of change in the environment as well as with in the system. Experimenting on real syste...

Production and manufacturing methods and the food carrier may influence the properties of probiotic strains, and have an impact on the outcome of clinical intervention studies. The aim of the present study was to establish whether the properties of a specific probiotic strain, Lactobacillus rhamnosus GG, may differ depending on the product and source of the strain. In total, fifteen different L...

One of important changes in manufacturing industry is that competition among individual companies has been extended to competition among the manufacturing networks surrounding the companies. Most manufacturing companies participate in various forms of collaboration to enhance competitive advantages in their arenas. In this paper, we introduce a data warehouse system that is designed for a manuf...
