The Management of Basic Production Functions

The production achieved in any industrial company is generically called basic production that needs an appropriate management that is different for every type of mass, serial, or individual production. Every type of production is based on a set of mathematical restrictions that quantitatively and qualitatively quantify that type of production. The fundamentals of the management of any basic production refers to: the production cycle that has a certain structure, and the total duration, the size of which considers both the way that product is made and the graph of moving the benchmarks from one operation to another; the manufacturing batch and, respectively, the optimal manufacturing batch, meaning the time elapsed between the release into production of two consecutive batches. A special case is the production achieved on a single object and multiple object flow manufacturing lines variably and constantly, continuously and discontinuously, etc. Every flow manufacturing line has a certain cadence, a certain tact, generates certain costs, and has certain characteristics. In the case of control production, it can be organised by taking into account the product position or the nature of the manufacturing process. Every type of production generates costs that are different in terms of the structure and calculation, and the use of the electronic calculation technique is imperatively necessary.

Preparation of Nitride Fuel by Spark Plasma Sintering Technique

SPS technique was applied for fabrication of UN pellets. The dense sample was obtained with relatively low sintering temperature without any milling process and sintering additive, indicating that the SPS technique is suitable for fabrication of nitride fuel. The thermal conductivity and Young's modulus in axial direction were higher than those of reported values. EBSP analysis and electronic calculation supposed that weak grain orientation in [100] direction of the sample lead to these higher values.

Determination of Tensile Properties by a Three-Point Method

It is shown that it is possible to use a three-point method for the evaluation of tensile data for some ductile metals. The experimental data show also that average tensile stresses and axial tensile stresses along the axis of the specimens during the necking portion of a test remain linear functions of the effective strain. Prediction made by the use of an electronic calculation sheet and the use of a computer program yield results which are in substantial agreement with the experimental results. The three-point method would seem to reduce the experimental work necessary to obtain σ versus ε curves and apparently would permit higher testing speeds than those of ε ≈ 0.03 used in this investigation.
