The extended Fibonacci sequence of numbers and polynomials is introduced and studied. The generating function, recurrence relations, an expansion in terms of multinomial coefficients, and several properties of the extended Fibonacci numbers and polyn

In this paper, we consider the renewal risk model and we are interested in the distribution of the number ? of claims until the first time that insurer's surplus process falls below zero (ruin) or exceeds a predefined upper barrier b u (safety level)

A two-sided run sum S control chart is proposed and its average run length performance is evaluated via a Markov chain technique. The performance of the chart is compared to several well-known control-charting procedures for the monitoring of process

Let T be a stopping time associated with a sequence of independent and identically distributed or exchangeable random variables taking values in {0, 1, 2, …, m}, and let S T,i be the stopped sum denoting the number of appearances of outcome 'i' in

In this paper, we introduce and study three new start-up demonstration tests with two types of unsuccessful start-ups. The proposed tests use run and frequency quotas acceptance/rejection criteria, providing extensions of binary start-up demonstratio

We investigate several aspects of the recently introduced consecutive successes distance failures start-up demonstration test under an exchangeable model. By assuming that the probability of a successful start-up attempt p is a random variable, inste

In this work, we introduce and study one-sided variable sampling interval S control charts supplemented with signalling and switching rules based on runs. The proposed control schemes demonstrate an improved performance in the detection of small and

The most common charting procedure used for monitoring the variance of the distribution of a quality characteristic is the S control chart. As a Shewhart-type control chart, it is relatively insensitive in the quick detection of small and moderate sh

Let Z 1 , Z 2 , … be a sequence of Bernoulli trials with success probability p = Pr ( Z t = 1 ) and failure probability q = Pr ( Z t = 0 ) = 1 − p , t ⩾ 1 . For positive integers k 1 and k 2 we consider the events E 1 : at least k 1 consecutive

To increase the sensitivity of Shewhart control charts in detecting small process shifts sensitizing rules based on runs and scans are often used in practice. Shewhart control charts supplemented with runs rules for detecting shifts in process varian
