We consider a continuous-review inventory system in which the setup cost of each order is a general function of the order quantity and the demand process is modeled as a Brownian motion with a positive drift. Assuming the holding and shortage cost to be a convex function of the inventory level, we obtain the optimal ordering policy that minimizes the long-run average cost by a lower bound appro...

Focusing on the effects of policy on investment and innovation this paper examines whether the conceptual foundations of sector regulation are aligned with the current technological and economic conditions of advanced communications. One conclusion is that the prevailing theories and practices are only adequate if the policy challenge can be reasonably approximated as a static or steady-state p...

Abstract: We prove that an (S, S) policy is optimal in a continuous-review stochastic inventory model with a fixed ordering cost when the demand is (i) a diffusion process and a compound Poisson process with exponentially distributed jump sizes, and (ii) a mixture of a constant demand and a compound Poisson process. The proof uses the theory of impulse control. The Bellman equation of dynamic p...

Good inventory management can plan, control, and manage the company's to consumer demand. Poor has a significant impact on company. Excess raw materials will affect high costs, lack of dissatisfied consumers. Therefore it is necessary have valid policy. This research aims minimize PT XYZ's costs using Continuous Review Periodic methods. The was conducted by taking data from XYZ then doing ABC a...

The last few decades have seen a growing emphasis on evidence-based decision making in health care. Systematic reviews synthesising research have been a key component of this movement. However, there is concern that such syntheses do not have the expected impact on policy with more work needed to enable us to maximise their potential. The aim of this review was to identify and evaluate potentia...
