Simultaneous production planning and scheduling has been identified as one of the most important factors that affect the efficient implementation of planning and scheduling operations for the production systems. In this paper, simultaneous production planning and scheduling is applied in a hybrid flow shop environment, which has numerous applications in real industrial settings. In this problem...

introduction: one of the serious problems in the further development of maize cultivation is increasing irrigation efficiency. using conventional irrigation causes a shortage of water resources to increase the acreage of the crop. with regard to the development of maize cultivation, agronomic and executable methods must be studied to reduce water consumption. using drip irrigation system is mos...

Flow and traffic-originated pollutant dispersion in an urban street canyon with avenue-like tree planting have been studied by means of wind tunnel and CFD investigations. The study comprises tree planting of different crown porosity, planted in two rows within a canyon of street width to building height ratio W/H = 2 and street length to building height ratio L/H = 10 exposed to a perpendicula...

Planning riparian restoration to resemble historic reference conditions requires an understanding of both local and regional patterns of plant species diversity. Thus, understanding species distributions at multiple spatial scales is essential to improve restoration planting success, to enhance long-term ecosystem functioning, and to match restoration planting designs with historic biogeographi...

The importance of soil factors to the establishment of tree crops is well recognized by forest soil scientists and foresters. It has, however, been overlooked by far too many foresters responsible for major forestation projects. The soil factors found to be significant in the establishment of both planted stock and seedlings from natural or artificial seedf all are: texture and structure charac...
