Consider a renewal risk model in which claim sizes and inter-arrival times correspondingly form a sequence of independent and identically distributed random pairs, with each pair obeying a dependence structure described via the conditional distribution of the inter-arrival time given the...

Asymptotic results are obtained for several conditional measures of association. The chosen random variables are the first two order statistics and the total sum within a random sum. Many of the results have confirmed the “one-jump” property of the risk model. Non-trivial limits are...

Purpose: Social manufacturing has emerged. It aims to integrate the manufacturing resources of micro- and small-scale manufacturing enterprises (MSMEs) and help MSMEs cope with the dynamic, service-oriented and personalized market demands. In social manufacturing, MSMEs cooperate with each...

This paper considers some univariate and multivariate operational risk models, in which the loss severities are modelled by some weakly tail dependent and heavy-tailed positive random variables, and the loss frequency processes are some general counting processes. In such models, we derive some...

This paper considers the randomly weighted sums generated by some dependent sub-exponential primary random variables and some arbitrarily dependent random weights. To study the randomly weighted sums with infinitely many terms, we establish a Kesten-type upper bound for their tail probabilities...

This paper considers a bivariate operational risk cell model, in which the loss severities are modeled by some heavy-tailed and weakly (or strongly) dependent non-negative random variables, and the frequency processes are described by two arbitrarily dependent general counting processes. In such...

In the current research, the efficiency of a hybrid renewable system consisting of a solar parabolic trough collector and the organic Rankine (PTC- ORC) is evaluated. Moreover, the effect of using the photovoltaic module in this coupled system (PTC-PV-ORC) is poked. Due to analyzing the...

Evacuated solar collectors are systems that provide a considerable quantity of heat. However, this system is unable to provide energy in the absence of sunlight. Thus, this study attempts to numerically study a Solar Evacuated Tube Collector (ETC) performance using phase change materials (PCM)....
