tendency to optimization in last decades has resulted in creating multi-product manufacturing systems. production planning in such systems is difficult, because optimal production volume that is calculated must be consistent with limitation of production system. hence, integration has been proposed to decide about these problems concurrently. main problem in integration is how we can relate pro...

background: a glycolipopeptide biosurfactant produced by pseudomonas aeruginosa strain ikw1 reduced the surface tension of fermentation broth from 71.31 to 24.62 dynes/cm at a critical micelle concentration of 20.80 mg/l. the compound proved suitable for applications in emulsion stabilization in food, as well as in cosmetic and pharmaceutical formulations. methods: in the present study, placket...

Increased yields of L-asparaginase from Erwinia aroideae NRRL B-138 were obtained by medium enrichment techniques coupled with aeration optimization.

The aim of the article is to choose algorithms suited for optimal placement of piles in real grillages by performing experimental comparison of different global optimization algorithms. The comparison includes several algorithms: random search, metaheuristics (simulated annealing and genetic algorithm) and local optimization combined with random search. The algorithms are compared using the res...
