Cardenas-Barron [L.E. Cardenas-Barron, Economic production quantity with rework process at a single-stage manufacturing system with planned backorders, Computers and Industrial Engineering 57 (2009) 1105–1113] minimizes the annual total relevant cost TC(Q , B) to find the economic production quantitywith rework process at amanufacturing system and assumes that TC(Q , B) is convex. So, the solut...

Fungal pathogens pose a major challenge to global crop production. Crop varieties that resist disease present the best defence and offer an alternative to chemical fungicides. Exploiting durable nonhost resistance (NHR) for crop protection often requires identification and transfer of NHR-linked genes to the target crop. Here, we identify genes associated with NHR of Arabidopsis thaliana to Pha...

The global food supply has been facing increasing challenges during the first decades of the 21st century. Disease in plants is an important constraint to worldwide crop production, accounting for 20-40% of its annual harvest loss. Although the use of resistant varieties, good water management and agronomic practices are valid management tools in counteracting plant diseases, there are still ma...

Advanced production planning tools in combination with powerful computing technology have reached the eye-line of product development tools, e.g. CAD-systems. The new tools offer planning and engineering support functions on the basis of 3-dimensional models and thus can easily be enhanced with 3d visualization facilities, e.g. a power-wall or a cave. Also they allow for an integrated viewing o...

This article describes the problem of transformation management systems in the area of planning and shop flow control of production. The authors present practical experience of building dedicated planning system and using pull logic of flow simulation in this process. The research works were carried out in industrial engineering in complex environmental conditions of production. This was a, mul...

the aim of the paper is to survey factors productivity in small & medium scale manufactories located in toos industrial town. in order to achieve this purpose, production functions of different industrial groups are estimated on the base of cross-section data in 2005. then elasticity of factors production, average productivity, marginal productivity, labor intensive and capital intensive are de...

Various traditional and industrial coke making techniques were discussed based on their limitations and production capacities, and the criteria such as the quality and size of coke production, amount of coke crumb, amount of investment, amount of operational costs, labor force and mechanization. In this work, the rankings of various traditional and industrial coke making techniques were carried...
