چکیده مقاله:

In quality control charts, the problem of determining the optimum process mean arises when the deviation of a quality characteristic in one direction is more harmful than in the opposite direction. The failure mode in these two directions is usually different. A great majority of researches in this area have considered asymmet-ric cost function for processes with single quality characteristics. In this paper, we consider processes in which there are more than one quality characteristics to monitor. The quality characteristics themselves may or may not be independent. Based upon the specification limits and the costs associated with the deviations we derive a formula to determine the optimum process mean. To illustrate the proposed formula and to estimate the costs associated with the optimum process mean we present four numerical examples by simulation. The re-sults of the simulation studies show that considerable amount of savings can be obtained by applying the pro-posed process means.

COVARIANCE MATRIX OF MULTIVARIATE REWARD PROCESSES WITH NONLINEAR REWARD FUNCTIONS

Multivariate reward processes with reward functions of constant rates, defined on a semi-Markov process, first were studied by Masuda and Sumita, 1991. Reward processes with nonlinear reward functions were introduced in Soltani, 1996. In this work we study a multivariate process , , where are reward processes with nonlinear reward functions respectively. The Laplace transform of the covar...

Non-Neutral Information Costs with Match-Value Uncertainty

This paper investigates a model featuring a monopolist seller and a buyer, with an uncertain valuation for the seller’s product. The seller chooses an information system (“IS”), allowing the buyer to receive a private signal, potentially correlated with her valuation. The cost of the IS is proportional to its precision, measured by the mutual information between the distributions of the buyer’s...

Transient Mesh Adaptation Using Conforming and Non Conforming Mesh Modifications

In this paper, we present a method for performing isotropic and anisotropic adaptive computations. The discontinuous Galerkin method that is used for solving transient flow problem is briefly introduced. We show then a general scheme to compute high-order derivatives of discontinuous fields. The Hessian of the density is used for computing a correction indicator. We present three sample problem...
