Abstract: The main objective of this work is to compare the
quality of service of the bus companies operating in the city of Rio
Branco, located in the state of Acre with the quality of service of the
bus companies operating in the city of Campos, situated in the state
of Rio de Janeiro, both cities in Brazil. This comparison, based on the
opinion of the bus users, will determine their degree of satisfaction
with the service available in both cities. The outcome of this
evaluation shows the users unhappy with the quality of the service
provided by the bus companies operating in both cities and the need
to identify alternative solutions that may minimize the consequences
caused by the main problems detected in this work. With these
alternatives available, the bus companies will be able to better
understand the needs of their customers in terms of manpower,
service cost, time schedule, etc.
Abstract: In this paper, the test purpose will be to assess
whether or not the accelerated model proposed by Eyring will be able
to translate results for the shape and scale parameters of an
underlying Weibull model, obtained under two accelerating using
conditions, to expected normal using condition results for these
parameters. The product being analyzed is a new type of insulate
fluid, and the accelerating factor is the voltage stresses applied to the
fluid at two different levels (30KV and 40KV). The normal operating
voltage is 25KV. In this case, it was possible to test the insulate fluid
at normal voltage using condition. Both results for the two
parameters of the Weibull model, obtained under normal using
condition and translated from accelerated using conditions to normal
conditions, will be compared to each other to assess the accuracy of
the Eyring model when the accelerating factor is only the voltage
stress.
