We study and compare the Shannon capacity region and the stable throughput region for a random access system in which source nodes multicast their messages to multiple destination nodes. Under an erasure channel model which accounts for interference and allows for multipacket reception, we first characterize the Shannon capacity region. We then consider a queueing-theoretic formulation and char...

energy policy making in the third millennium is summarized in three areas. the first area: moving toward the use of renewable, clean and environment compatible energy, the second area: restructuring in the energy sector, to make it competitive, & finally, the third area is: increasing efficiency in energy consumption. power industry as a growing sub-section of energy sector, especially in recen...

As capacity demands vary among simultaneously executed threads in chip multiprocessors, dynamically managing cache resources according to the run-time demands is effective to improve L2 cache performance. Differed from existing dynamic cache management schemes based on LRU replacement policy, we propose an adaptive capacity sharing mechanism based on a global reuse replacement policy. This mech...

This study aims to analyze the policy capacity in employee management General Functional Class Government of Bangkalan Regency. The problem is that availability position classes has not been accommodated Regent Regulation Number 75 2020 for several job classes. raises problems such as placing employees a lower class than they should be, are still fulfilled, causing jealousy between employees. u...

Coalitions are the most common platform for implementing community-level environmental strategies (ES), such as media, policy, or enforcement for substance use prevention. The current study examines the associations between two types of coalition capacity (general and innovation-specific) and ES implementation efforts and outputs within 14 intervention communities over a three-year period. Effo...

This paper presents the optimality condition, Bellman’s equation, and an optimal job sequencing policy for a benchmark reentrant line (RL) with finite capacity buffers. The optimal policy is obtained for an infinite horizon discounted cost criterion, and is characterized by an index which is a function of the one-stage cost function and system’s parameters. In addition, when the buffer levels a...

We study the optimal production-inventory-outsourcing policy for a firm with Markovian in-house production capacity that faces independent stochastic demand and has the option to outsource. We find very simple optimal policy forms under fairly reasonable assumptions. In addition, when the capacity Markov process is stochastically monotone, the policy parameters decrease in the firm’s current ca...
