The business world is becoming more competitive. Therefore, it crucial to increase the flexibility of production by decreasing time used in processes preparing lines for new items’ production, reducing changeover and setup times. This paper presents a case study where main goal reduce welding robots. Single Minute Exchange Die (SMED) was implemented, using other tools such as Spaghetti Diagram,...

The article presents the results of use quality instruments – tools and techniques in order to reduce surface defects steel structures on example a selected element engine cover asphalt milling machines. shows potential using basic new service analysis improvement. Quantitative analyzes were presented out Pareto-Lorenz diagram c control chart, qualitative Ishikawa FMEA method, quantitativ...

One of sheet severe plastic deformation (SPD) operation, namely constrained groove pressing (CGP), is investigated here in order to specify the optimum values for geometrical variables of this process on pure aluminium sheets. With this regard, two different objective functions, i.e. the uniformity in the effective strain distribution and the necessary force per unit weight of the specimen, are...

When implementing software for programmable digital signal processors (PDSPs), the design space is de ned by a complex range of constraints and optimization objectives. Three implementation metrics that are crucial in many PDSP applications are the program memory requirement (code size), data memory requirement, and execution time. This paper addresses the problem of exploring the 3-dimensional...

This study deals with the cumulative pitch variations in DIN male contacts. A connector provides a separable interface between two subsystems of an electronic system. DIN is a series of connector which stands for Deutsch Institut fur Normung. They are used for applications like switching, transmission, radio base stations, control units and machines. Connector manufacturing involves stamping, m...

We study two related versions of the no-impatience postulate in the context of transitive and reflexive relations on infinite utility streams which are not necessarily complete. Both are excluded by the traditional (weak) anonymity axiom. We show explicit social welfare relations satisfying Strong Pareto and the weaker version of noimpatience that are compatible with continuity in all the tradi...

A new direct-space method for ab initio solution of crystal structures from powder diffraction diagrams is presented. The approach consists of a combined global optimization (`Pareto optimization') of the difference between the calculated and the measured diffraction pattern and of the potential energy of the system. This concept has been tested successfully on a large variety of ionic and inte...
