Impact of Excessive Stocks in Process of Bearing Stock Optimization Using Branch and Bound Method
Supply process is one of major priorities for each manufacturing plant. To produce quality products with low prices is an advantage in competition on the market. A prerequisite for such a state is to minimize prices of production inputs, which can be achieved by stock optimizing. Presented contribution on specific example illustrates discrete optimization process on principles of Branch & Bound, which defines the input, and optimized parameters of initial stock of bearings in selected companies operating on Slovak market. In conclusion, the impact of optimized solutions is given and highlights the need for optimization.
Virtual Machining and its Experimental Verification
Virtual Machining and its Experimental Verification Research, verification and implementation of various methods of rapid prototyping are getting more intensified in the recent time. One of possible rapid prototyping techniques is a virtual machining which allows testing the properties of designed machine tool using its mathematical model. This article presents the example of virtual machining on a virtual small centre lathe and experimental verification of obtained results.
Research requirements to reduce maintenance costs of civil helicopters
The maintenance problems faced by the operators of civil helicopters that result in high costs are documented. Existing technology that can be applied to reduce maintenance costs and research that should be carried out were identified. Good design practice and application of existing technology were described as having a significant impact on reducing maintenance costs immediately. The research and development that have potential for long range reduction of maintenance costs are presented.
