HIERARCHICAL COMPUTATION OF HERMITE SPHERICAL INTERPOLANT
2
2
In this paper, we propose to extend the hierarchical bivariateHermite Interpolant to the spherical case. Let $T$ be an arbitraryspherical triangle of the unit sphere $S$ and let $u$ be a functiondefined over the triangle $T$. For $kin mathbb{N}$, we consider aHermite spherical Interpolant problem $H_k$ defined by some datascheme $mathcal{D}_k(u)$ and which admits a unique solution $p_k$in the space $B_{n_k}(T)$ of homogeneous BernsteinB'ezierpolynomials of degree $n_k=2k$ (resp. $n_k=2k+1$) defined on $T$. Wediscuss the case when the data scheme $mathcal{D}_{r}(u)$ arenested, i.e., $mathcal{D}_{r1}(u)subset mathcal{D}_{r}(u)$ forall $1 leq r leq k$. This, give a recursive formulae to computethe polynomial $p_k$. Moreover, this decomposition give a new basisfor the space $B_{n_k}(T)$, which are the hierarchical structure.The method is illustrated by a simple numerical example.

A SINGLE SERVER BERNOULLI VACATION QUEUE WITH TWO TYPE OF SERVICES AND WITH RESTRICTED ADMISSIBILITY
2
2
A single server queue with Bernoulli vacation has been considered. In addition the admission to queue is based on a Bernoulli process and the server gives two type of services. For this model the probability generating function for the number of customers in the queue at different server's state are obtained using supplementary variable technique. Some performance measures are calculated. Some particular cases are obtained and numerical examples are also presented.

NUMERICAL SOLUTION OF THE MOST GENERAL NONLINEAR FREDHOLM INTEGRODIFFERENTIALDIFFERENCE EQUATIONS BY USING TAYLOR POLYNOMIAL APPROACH
2
2
In this study, a Taylor method is developed for numerically solving the highorder most general nonlinear Fredholm integrodifferentialdifference equations in terms of Taylor expansions. The method is based on transferring the equation and conditions into the matrix equations which leads to solve a system of nonlinear algebraic equations with the unknown Taylor coefficients. Also, we test the method by numerical examples

A NEW MODIFIED HOMOTOPY PERTURBATION METHOD FOR SOLVING LINEAR SECONDORDER FREDHOLM INTEGRODIFFERENTIAL EQUATIONS
2
2
In this paper, we tried to accelerate the rate of convergence in solving secondorder Fredholm type Integrodifferential equations using a new method which is based on Improved homotopy perturbation method (IHPM) and applying accelerating parameters. This method is very simple and the result is obtained very fast.

COST MALMQUIST PRODUCTIVITY INDEX IN SUPPLY CHAIN
2
2
The index is excellent by the Malmquist index as extended to productivity measurement. The index developed here is defined in terms of input cost rather than input quantity distance functions in supply chain. Therefore, we propose productivity change is decomposed into overall efficiency and cost technical change. These decompositions provide a clearer situation of the root sources of supply chain productivity change, so that illustrated here in a sample of supply chain; so that results are computed using nonparametric mathematical programming.

DESIGN AND DEVELOPMENT OF THE STRATEGY TO IMPROVE PATIENT SATISFACTION IN A HOSPITAL SETTING
2
2
Attempts made in order to improve management tools of performance showing the importance of customer satisfaction in determining the organizations’ success in profitability and business. The main objective of this study was to develop appropriate strategies to improve patient satisfaction in Hospital.
The research was a descriptivepractical one. Data was collected through a brainstorming session, two questionnaires designed based on internal and external evaluation matrices standard framework and quantitative strategic programming matrix, and finally some changes were made. Having collected the data, vision and mission of the hospital were developed; then SWOT matrix of the hospital was formed and due to the hospital being placed in competitive position (ST), five strategies were considered necessary to improve the satisfaction of the hospital’s patients.
What was considered the most was appointing a strategy in order to attract specialists and efficient forces with a score of 5.56 and the least considered referred to the strategy of promoting the empowerment of newlyhired staff with a score of 2.96.
The population of this study is comprised of experts and senior managers at one of the hospital in Tehran working in 2012 (N=16).
Due to the limited number of population, sampling was not done. Tools of collecting data included brainstorming session and two questionnaires.
