Average fill rate and horizon length
نویسندگان
چکیده
Given a sequence of iid demands and an order up to replenishment policy with negligible lead time, we prove that average fill rate is monotonically decreasing in the number of periods in the planning horizon. This was conjectured to be true in a recent issue of this journal.

Finite Capacity Queuing System with Vacations and Server Breakdowns
This paper deals with finite capacity single server queuing system with vacations. Vacation starts at rate nu if the system is empty. Also the server takes another vacation if upon his arrival to the system, finds the system empty. Customers arrive in the system in Poisson fashion at rate lamda0 during vacation, faster rate lamdaf during active service and slower rate lamdas during the breakdow...
متن کاملComparing the Microleakage of Bulk-Fill (flowable, packable) Composite Restorations and Conventional Light-cured Composites
Introduction and aim: Bulk Fill composites have increased polymerization depth and their contraction stress, and cuspal deflection are reduced in comparison with conventional composites. Therefore, it is claimed that their microleakage is reduced. The aim of this study was to compare microleakage of (flowable and packable) Bulk Fill and conventional resin composites. Materials and Methods: Thi...
متن کاملLong Strange Segments, Ruin Probabilities and the Effect of Memory on Moving Average Processes
We obtain the rate of growth of long strange segments and the rate of decay of infinite horizon ruin probabilities for a class of infinite moving average processes with exponentially light tails. The rates are computed explicitly. We show that the rates are very similar to those of an i.i.d. process as long as moving average coefficients decay fast enough. If they do not, then the rates are sig...
متن کاملManaging an Assemble-to-Order System with Returns
W consider a multiproduct assemble-to-order (ATO) system, in which inventory is kept only at the component level and the finished products are assembled in response to customer demands. In addition to stochastic demand for finished products, the system experiences stochastic returns of subsets of components, which can then be used to satisfy subsequent demands. The system is managed over an inf...
متن کاملDynamic Control of a Queue with Adjustable Service Rate
We consider a single-server queue with Poisson arrivals, where holding costs are continuously incurred as a non-decreasing function of the queue length. The queue length evolves as a birth-and-death process with constant arrival rate λ = 1 and with state-dependent service rates μn that can be chosen from a fixed subset A of [0,∞). Finally, there is a non-decreasing cost-of-effort function c(·) ...
