BACKGROUND The relation between physical access in emergency department ‎(ED) and the time patients have to wait before being served is unknown. OBJECTIVES Our objective was to discover the associations between the physical access in ED and the time patients had to wait before receiving services. MATERIALS AND METHODS In this cross-sectional study, statistical society comprised two portions...

Models of double-source queuing-inventory systems are studied in the presence a finite buffer for waiting queue consumer customers, where instant destruction inventory is possible. It assumed that lead times orders, as well cost delivery from various sources, differ each other. Replenishment stocks sources carried out according to following scheme: if level drops reorder point s, then regular o...

today, in a competitive market, service organizations and producers have a great attention to optimization and customer satisfaction in order to become competitive. service organization must reduce the number of arrival, waiting time and service time in the queue to increase the customer satisfaction. in this paper by the aim of queuing theory we analyze the optimal amount of increment in a rep...

the purpose of the present study is to introduce the sequence space[{l_p}(e,delta) = left{ x = (x_n)_{n = 1}^infty : sum_{n = 1}^infty left| sum_{j in {e_n}} x_j - sum_{j in e_{n + 1}} x_jright| ^p < infty right},]where $e=(e_n)$ is a partition of finite subsets of the positive integers and $pge 1$. the topological properties and inclusion relations of this space are studied. moreover, the prob...

Waiting for care has been and continues to be a major issue for the healthcare sector in Canada. While considerable gains have been made regarding valid and reliable information on waiting times, gaps remain. Statistics Canada continues to provide information regarding patients' experiences in accessing care at the national and provincial levels, including how long individuals waited for specia...
