This paper presents the design of a Knowledge Based Material Handling System (KBMHS) used for transporting part types between machining centres and load, unload stations. The KBMHS is one of the modules of the Knowledge Based Flexible Manufacturing’ System Design (KBFMSD), which is able to design a complete FMS.A hybrid knowledge base and an optimization approach for the selection of the Material handling System (MHS) and reduction of handling cost is used. Depending on the input parameters, the knowledge base selects suitable material handling systems for transportation of parts between loading, unloading and machining centres, while the analytical part finds the optimal handling cost and cost of the MHS. The KBMHS is developed in AM: an expert system shell. The application of the system is demonstrated with the help of an example<\div>

Among the 30 strains of moderately halophilic bacteria isolated from the salty effluents of textile industries around Qom city in central Iran, a Gram–negative rod shape bacterium designated as strain IP8 showed a remarkable ability in decolorizing of azo dyes over wide ranges of pH (7–11) and temperature (25–45 ºC), in presence of NaCl and Na2SO4 (0.5–1.5 M) under anaerobic and aerobic conditions. Phenotypic characterization and phylogenetic analysis based on 16S rDNA sequence comparisons indicated that this strain was a member of the genus Halomonas with the greatest similarity to Halomonas axialensis. UV–Vis analysis before and after decolorization and the colorless bacterial biomass after treatment suggested that decolorization was due to biodegradation. HPLC analysis of dye treatment confirmed that the principal biodegradation was occurred after 48h of incubation in aeration culture. The effect of metal salts on decolorization showed that AgNO3 and NaAsO4 were of higher and lower effect on decolorization, respectively.
