چکیده

We analyze the Two Level Processor Sharing (TLPS) scheduling discipline with hyperexponential distribution for the job size and with Poisson arrival process. TLPS is a convenient model to represent the file size based differentiation in TCP/IP networks. We find a closed form analytic expression for the expected sojourn time and an approximation for the optimal value of the threshold that minimizes the expected sojourn time.

Optimal Call Admission Control in Generalized Processor Sharing (GPS) Schedulers

Generalized Processor Sharing(GPS) is an idealized fluid discipline with a number of desirable properties. Its packetized version PGPS is considered to be a good choice as a packet scheduling discipline to guarantee Quality-of-Service in IP and ATM networks. The existing Connection Admission Control(CAC) frameworks for GPS result in a conservative resource allocation. We propose an Optimal CAC ...

Ultra-Low-Energy DSP Processor Design for Many-Core Parallel Applications

Background and Objectives: Digital signal processors are widely used in energy constrained applications in which battery lifetime is a critical concern. Accordingly, designing ultra-low-energy processors is a major concern. In this work and in the first step, we propose a sub-threshold DSP processor. Methods: As our baseline architecture, we use a modified version of an existing ultra-low-power...

Deriving the Exact Cost Function for a Two-Level Inventory System with Information Sharing

In this paper we consider a two-level inventory system with one warehouse and one retailer with information exchange. Transportation times are constant and retailer faces independent Poisson demand. The retailer applies continuous review (R,Q)-policy. The supplier starts with m initial batches (of size Q), and places an order to an outside source immediately after the retailer’s inventory posit...

Three-stage mining metals supply chain coordination and air pollutant emission reduction with revenue sharing contract

One of the main concerns of all industries such as mine industries is to increase their profit and keep their customers through improving quality level of their products; but increasing the quality of products usually releases air pollutants. Nowadays the management of air pollutant emissions with harmful environmental and health effects is one of the most pressing problems. In this paper, auth...

DC Voltage Control and Power-Sharing of Multi-Terminal DC Grids Based on Optimal DC Power Flow and Flexible Voltage Droop Strategy

This paper develops an effective control framework for DC voltage control and power-sharing of multi-terminal DC (MTDC) grids based on an optimal power flow (OPF) procedure and the voltage-droop control. In the proposed approach, an OPF algorithm is executed at the secondary level to find optimal reference of DC voltages and active powers of all voltage-regulating converters. Then, the voltage ...
