In this article we develop a model for determining the appropriate level of inspection sampling for any manufacturing process. The model is useful for manufacturers, who naturally are concerned with profits and therefore with minimizing the cost of production. The model design aims to reduce total manufacturing cost and has general applicability to various(More)
The instant system availability [Formula: see text] of a repairable system with the renewal equation was studied. The starting point monotonicity of [Formula: see text] was proved and the upper bound of [Formula: see text] is also derived. It was found that the interval of instant system availability monotonically decreases. In addition, we provide examples(More)
Manganese-oxidizing microorganisms are able to oxidize soluble Mn<sup>2+</sup> into insoluble Mn oxides, so they are very useful in treatment of Mn-contaminated water. A strain bacteria Mn-103 was isolated, purified from manganese removal bio-filter treated, and it had been identified to belong to Bacillus ce-1 by the MIDI Sherlock bacteria identification(More)
