Complex Planning

Mit zunehmender Produktvielfalt steigen die Anforderungen an die Planung von Montagelinien. Um diese Komplexität zu bewältigen, werden Montageprozesse virtuell simuliert. Der Aufwand zur Aufbereitung bestehender CAD-Anlagenmodelle zu Simulationsmodellen ist aber sehr hoch. Daher werden mit der hier vorgestellten Methodik CAD-Modelle automatisiert für die Simulation aufbereitet. Ziel ist, die benötigte Zeit, Expertise und das Fehlerpotenzial der Modellaufbereitung deutlich zu reduzieren und die Wirtschaftlichkeit des Simulationseinsatzes in der Montage zu steigern.   Machine-oriented simulation helps to cope with complex planning processes for assembly systems. However, the effort to prepare existing CAD models for machine-oriented simulations is very high. Therefore, a method is presented for the automated preparation of CAD models for assembly simulation. Applying this method reduces significantly the required time, expertise and potential errors in model preparation while increasing the economic efficiency of simulation use in assembly.

Research highlights the importance of potato crop, which occupies a prominent food and economic status in food security besides rice, wheat and corn at the local and global level. Despite the expansion of the cultivation of potato crop in Iraq in general and Ameriyah district in particular However, potato productivity remains substandard, this may be due to a lack of knowledge of the most efficient varieties and not to use productive resources at the levels at which technical, specialized and economic efficiency is achieved. Therefore, the aim of the research is to determine the technical, specialized and economic efficiency according to the cultivated seed category. The data envelope analysis (DEA) method was used to estimate technical, specialized and economic efficiency, assuming constant and variable capacity returns. As a result of the study, the Safrana variety achieved the highest average technical efficiency according to the stability of the yield and capacity efficiency in addition to achieving the highest average specialized and economic efficiency, The Lapadia variety achieved the highest average technical efficiency, assuming that capacity returns have changed. Therefore, we recommend the adoption of items that achieve higher efficiency and the need to redistribute the elements of production better and Achieving the optimum levels at which technical, specialized and economic efficiency is achieved and saving what has been wasted.
