In this paper, we consider a single-stage manufacturing system with one machine, which makes a single product to stock to satisfy random demand. Customers inter-arrival times and production times are all exponential random variables. In order to represent customer impatience behavior caused by backlog, we employ a balking function, which is an arbitrary non-decreasing function of the backlogged...

This paper considers the problem of conserving energy in a single node in a wireless sensor network by turning off the node’s radio for periods of a fixed time length. While packets may continue to arrive at the node’s buffer during the sleep periods, the node cannot transmit them until it wakes up. The objective is to design sleep control laws that minimize the expected value of a cost functio...

Compound TCP (CTCP) is a sender-side improvement for TCP in high-speed and long distance networks. CTCP is a synergy of delay and loss-based congestion control, effectively combining them to achieve good efficiency, RTT fairness and TCP-friendliness. However, CTCP requires detecting incipient congestion effectively by estimating the backlogged packets and comparing it to a pre-defined parameter...

Abstract—It has been widely recognized that bistable behavior of random access protocols may suddenly deteriorate the performance of the system due to the unexpected slip into an undesired stable operating point. The catastrophe theory succeeds in presenting the bistable region of random access protocols, where packet retransmissions occur in a memoryless manner. In this correspondence, the sta...

Purpose: The purpose of this paper to develop an inventory model for instantaneous deteriorating items with the consideration of the facts that the deterioration rate can be controlled by using the preservation technology (PT) and the holding cost & demand rate both are linear function of time which was treated as constant in most of the deteriorating inventory model. Design/methodology/approac...

Commodity WiFi-based Wireless Mesh Networks (WMNs) can be used to provide last mile Internet access. These networks exhibit extreme unfairness with backlogged traffic sources. Current solutions propose distributed source rate control algorithms requiring MAC or transport-layer changes on all mesh nodes. This is often infeasible in large practical deployments. In wireline networks, router-assist...

This paper deals with the production-dependent failure rates for a hybrid manufacturing/remanufacturing system subject to random failures and repairs. The failure rate of the manufacturing machine depends on its production rate, while the failure rate of the remanufacturing machine is constant. In the proposed model, the manufacturing machine is characterized by a higher production rate. The ma...

We consider a set of transmitter-receiver pairs, or links, that share a wireless medium, and address the problem of emptying backlogged queues with given initial size at the transmitters in minimum time. The minimum-time scheduling problem (MTSP) amounts to determining activation subsets of links, and their time durations, to form a minimum-time schedule. This scheduling problem has been studie...

Most of production inventory systems is interested in determining the optimal stopping and restarting times of producing certain commodity. In this paper, a multi-item production inventory model under resource constraints is considered. For any product, each of the production, the demand, and the deterioration rates in any cycle as well as all cost parameters are treated as known and arbitrary ...

Managing component inventories eeectively in assembly systems with several products that share many common components can lead to improved customer service. We consider a two-level, nite-horizon assembly problem with multiple end-products that have random demands and share several common components. The objective is to minimize the total cost which comprises of holding excess components and pay...
