the main objective in sampling is to select a sample from a population in order to estimate some unknown population parameter, usually a total or a mean of some interesting variable. a simple way to take a sample of size n is to let all the possible samples have the same probability of being selected. this is called simple random sampling and then all units have the same probability of being ch...
We consider a periodic-review, serial inventory system, in which each stage replenishes inventory according to an echelon-stock (r, nQ, T ) policy – a standard echelon-stock (r, nQ) policy executed every T periods. Demands are independent, identically distributed in different periods and occur at the most downstream stage. Two types of fixed costs are considered: setup cost and replenishment co...
in order to examine the ecological conditions and characteristics of fraxinus excelsior l. in the northern forests of iran 6 main areas as well as some miscellaneous ones , have been selected in the region respectively in : lomir2, shafaroud , park - e-noor , ahlam , alandan and noor.
In this paper we study a periodic review single item single stage inventory system with stochastic demand. In each time period the system must order none or at least as much as a minimum order quantity Qmin. Since the optimal structure of an ordering policy with a minimum order quantity is complicated, we propose an easy-to-use policy, which we call (R,S,Qmin) policy. Assuming linear holding an...
abstract: about 60% of total premium of insurance industry is pertained?to life policies in the world; while the life insurance total premium in iran is less than 6% of total premium in insurance industry in 2008 (sigma, no 3/2009). among the reasons that discourage the life insurance industry is the problem of adverse selection. adverse selection theory describes a situation where the inf...
In this paper we consider a periodic review order-up-to inventory system with capacitated replenishments, lost sales and zero lead time. We consider discrete demand. It is shown that the initial stock levels of the different review periods form aMarkov chain andwe determine the transitionmatrix. Furthermore we study for what probabilitymass functions of the review period demand theMarkov chain ...
In order to investigate the effects of non-linear springs in vibrating behavior of vehicles, the independent suspension of conventional vehicles could be modeled as a non-linear single degree of freedom system. The equation of motion for the system would be a non-linear third order ordinary differential equation, when considering the elasticity of rubber bushings in joints of shock absorber. It...
the present study set out (a) to examine the categories of pedagogical knowledge related to the act of teaching of novice and experienced teachers as gleaned from their verbal report of what they were thinking about while teaching and (b) to compare the categories of pedagogical knowledge of novice and experienced teachers. the aim of comparing these two groups of teachers was to see whether di...
