In this contribution we present analysis and simulation results on controlling TCP rates by buffer allocation When segment loss is low TCP throughput depends primarily on the TCP window size and the round trip time of the connection As a result it is possible to control TCP rates with FIFO queuing We present a buffer management policy called Differential Fair Buffer Allocation that provides loo...

The recent deployment of complex and capital intensive equipment in mines has resulted in increased interest in the maintenance and operational reliability of these equipments. This is because random equipment failure has consequences that influence the total operating cost of this system. This case study analyses the reliability of a fleet of load haul dump machines in a Coal India mine situat...

preventive maintenance scheduling is to perform a series of tasks that prevents or minimizes production breakdowns and improves the reliability. mathematical models have been developed to solve the preventive maintenance scheduling problem. there are several limitations in the prior work in this area of research. craft combinations are assumed to be given. the craft combination problem concerns...

in this paper, we consider a flow shop scheduling problem with availability constraints (fsspac) for the objective of minimizing the makespan. in such a problem, machines are not continuously available for processing jobs due to preventive maintenance activities. we proposed a mixed-integer linear programming (milp) model for this problem which can generate non-permutation schedules. furthermor...

This paper presents a linear programming approach to analyze and optimize flow lines with limited buffer capacities and stochastic processing times. The basic idea is to solve a huge but simple linear program that models an entire simulation run of a multi-stage production process in discrete time, to determine a production rate estimate. As our methodology is purely numerical, it offers the fu...

Fluid flow models have been used in performance evaluation of production, computer, and telecommunication systems. Currently, a general methodology to model and analyze a given continuous flow production system is not available. In order to develop a general methodology to analyze Markovian continuous material flow production systems with a finite buffer, we modelled the fluid flow system as a ...

Buffering of intermediate results in dataflow diagrams can significantly reduce latency when a user browses these results or re-executes a diagram with slightly different inputs. We define the optimal buffer allocation problem of determining the buffer contents which minimize the average response time to such user requests. We show that this problem has several characteristics which render trad...

In credit-based flow control for ATM networks, buffer is jirst allocated to each VC (virtual circuit) and then credit control is applied to the VC for avoiding possible buffer overjow. Receiveroriented, adaptive buffer allocation allows a receiver to allocate its buffer dynamically, to VCs from multiple upstream nodes based on their bandwidth usage. This paper describes, in detail, such an adap...
