چکیده

1 Abstract. This paper is concerned with the optimal production planning in a dynamic stochastic manufacturing system consisting of a single or parallel machine that are failure prone and facing a constant demand. The objective is to choose the rate of production over time in order to minimize the long-run average cost of production and surplus. The analysis proceeds with a study of the corresponding problem with a discounted cost. It is shown using the vanishing discount approach that the Hamilton-Jacobi-Bellman equation for the average cost problem has a solution giving rise to the minimal average cost and the so-called potential function. The result helps in establishing a veriication theorem. Finally, the optimal control policy is speciied in terms of the potential function.

Hierarchical Production Control in a StochasticManufacturing System with Long - Run Average Cost 1

This paper presents an asymptotic analysis of a stochastic manufaturing system consisting of parallel machines subject to breakdown and repair and facing a constant demand, as the rates of change of the machine states approach in nity. This situation gives rise to a limiting problem in which the stochastic machine availability is replaced by its equilibrium mean availability. The long-run avera...

Improving Long Run Marginal Cost based Pricing along with Extended Benefit Factor method for Revenue Reconciliation of Transmission Network in Restructured Power System

Abstract : There are several methods to cover the costs of a transmission system and distribution networks. These methods are divided into either incremental or marginal approaches, which can be either long-term or short-term. The main difference between the incremental and marginal approach is how to calculate the cost of using the network. In the incremental approach, simulation and in the ma...

The Long Run Impact of Technology Diffusion on Average Cost in Upstream Oil Industry; Case Stud of Iran

Literature review related to nonrenewable resources shows that technological improvements have considerable effects on resource depletion and decreasing operational cost.  Therefore it is assumed that technology is the most important and influential variables in the production function and utilization cost of these resources. In this study, we assess the long term effect of technology diffusion...

A Queueing-Inventory System with Repair Center for Defective Items and One-for-One Ordering Policy

In this paper we consider a system consisting of a supplier with a single processing unit, a repair center, and a retailer with Poisson demand. We assume that the retailer applies one-for-one ordering policy with backorders for his inventory control. The retailer’s orders form a queue in the supplier processing unit. We also assume that a certain fraction of the products produced by the supplie...
