Proper scheduling of tasks leads to optimum using of time and resources, in order to obtaining best result. One of the most important and complicated scheduling problems is open shop scheduling problem. There are n jobs in open shop scheduling problem which should be processed by m machines. Purpose of scheduling open shop problem is attaining to a suitable order of processing jobs by specified...

in this paper, an exact geometric algorithm is presented for solving two-job sequencing and scheduling problems in flexible flow shop and job shop environments while the resources are (un)available in some time periods and processors (un)availability is the same in all work centers. this study seems utterly new and it is applicable to any performance measure based on the completion time. the in...

This paper represents the metaheuristics proposed for solving a class of Shop Scheduling problem. The Bacterial Foraging Optimization algorithm is featured with Ant Colony Optimization algorithm and proposed as a natural inspired computing approach to solve the Mixed Shop Scheduling problem. The Mixed Shop is the combination of Job Shop, Flow Shop and Open Shop scheduling problems. The sample i...

The FLO gene family of Saccharomyces cerevisiae includes an expressed gene, FLO11, and a set of silent, telomere-adjacent FLO genes. This gene family encodes cell-wall glycoproteins that regulate cell-cell and cell-surface adhesion. Epigenetic silencing of FLO11 regulates a key developmental switch: when FLO11 is expressed, diploid cells form pseudohyphal filaments; when FLO11 is silent, the ce...

FLORICAULA (FLO) of Antirrhinum and LEAFY (LFY) of Arabidopsis encode plant-specific transcription factors, which are necessary and sufficient to specify floral meristem identity. We isolated WFL, a wheat FLO/LFY ortholog, and analyzed its expression pattern. RT-PCR analysis indicated that WFL is expressed predominantly in young spike. The WFL expression pattern during reproductive development ...
