Introduction Being in a queue (waiting line) is an inevitable fact of our daily life‚ such as waiting for checkout at a supermarket‚ or waiting to make a bank deposit. Queuing theory‚ started with research by Agner Krarup Erlang‚ is used to examine the impact of management decisions on these waiting lines (Anderson et.al‚ 2009). A basic Queuing Model structure consists of three main characteristics‚ namely behaviour of arrivals‚ queue discipline‚ and service mechanism (Hillier and Lieberman‚ 2001)

state) be P(L) = 0.5 We assume that the amount of utility or satisfaction Ajay derives from a payoff is equal to the square root of the amount of the payoff. So‚ we get Ui(a) = √x‚ x≥0 Where x is the amount of the payoff The decision theory tells us that the act with the highest expected utility should be chosen. We denote the expected utility of act a1 (AB Ltd.) by EU(a1) and the expected utility of act a2 (XY Ltd.) by EU(a2). Thus‚ we get EU(a1) = 0.5 x √1089 + 0.5 x √0 =

INTRODUCTION The primary subject of Risk Theory is the development and study of mathematical and statistical models to describe and predict the behaviour of insurance portfolios‚ which are simply financial instruments composed of a (possibly quite large) number of individual policies. For the purposes of this course‚ we will define a policy as a random (or stochastic) process generating a deterministic income in the form of periodic premiums‚ and incurring financial

She is one of the very first nurse anthropologists that recognized care and culture as two major significant phenomena in nursing (Leininger.2002). Care according to Leininger’s concepts has different meaning in different cultures but in general‚ care refers to assistive or supportive behaviors that improve an individual’s condition (Leininger.2002). According to Madeleine Leininger‚ care is essential

society. Equity theory is social justice theory‚ designed by Adams in 1963. It claims that individuals review the inputs and outcomes of themselves and others‚ and in situations of inequity‚ experience greater cognitive dissonance than individuals in equitable situations. This kind of equity is perceived as social justice in society (or company‚ or any other environment that involves individuals). Equity theory draws from exchange‚ dissonance‚ and social comparison theories in making predictions
