The maintenance strategy is a tradeoff between cost and reliability. In this paper we consider the maintenance plan from the view of economic life cycle cost and reliability. We discuss the maintenance interval optimization on the premise that the preventive maintenance mitigates failure rate level and intensifies failure variance ratio meanwhile. The specific effect of this kind of preventive maintenance on failure rate and its variance ratio is explored, and then we construct a life cycle cost model of electric power equipment and propose the annuity of life cycle cost minimization as a method for seeking an optimal maintenance interval solution.

Phacelia Tanacetifolia

AbstractIn 2010 the experiment, which aim was to examine the sowing value of tansy phacelia seeds after eight and nine years of storage, was conducted in the laboratory of the Academy of Agrobusiness in Łomża. The experiment clearly demonstrates that the period of storage of tansy phacelia seeds has an essential impact on the changes of basic parameters of the sowing value. Vetrovska variety had the highest seed germinability among the other varieties of tansy phacelia which were stored for 8 years. At the same time this variety had the highest decrease in seed germinability after 9 years of storage. During the 9-year storage Natra variety showed the highest decrease in thousand seeds weight despite the highest value of this parameter among all the tested varieties immediately after yielding. The results; of the experiment allowed for the conclusion that the economic life: cycle of tansy phacelia seeds is 8 years.
