A methodology to customize pull control systems
Journal of the Operational Research Society, 2001Summary: The objective of this paper is to develop a methodology for customizing pull control systems, replacing traditional control systems such as Kanban, Conwip, and Base Stock. The basic principle is to start with a pull control system that connects each stage of a given production line with each preceding stage; next, the optimization of the ...

Introduction to load-pull systems and their applications
IEEE Instrumentation & Measurement Magazine, 2013Large-signal or non-linear characterization of transistor devices is essential for determining their performance in such non-linear applications as power amplifiers (PAs), considering the limitations of linear S-parameter characterization techniques in such applications.

Customer Service in Pull Production Systems
Operations Research, 1992In this paper, we consider the issue of customer service in pull production systems. We first discuss the meaning of customer service in a pull system and contrast it to push systems. We also discuss both pure and hybrid pull systems that are found in the literature.

Optimal control of pull manufacturing systems
IEEE Transactions on Automatic Control, 1995Summary: We consider the problem of optimal control of pull manufacturing systems. We study a fluid model of a flow shop, with buffer holding costs nondecreasing along the route. The system is subject to a constant exogenous demand, thus incurring additional shortfall/inventory costs. The objective is to determine the optimal control for the production

Data broadcasting has emerged as an efficient way for the dissemination of information over asymmetric wireless environments where the needs of the various users of the data items are usually overlapping. In such environments, data broadcasting stands to be an efficient solution since the broadcast of a single information item is likely to satisfy a ...

Pulling effect in synchronized systems
Proceedings of the IEE - Part IV: Institution Monographs, 1954Synchronization of a certain type of valve oscillator, having a low-pass filter in the synchronization loop, and also of self-starting synchronous motors is examined. Under some conditions the pulling effect takes place in these circuits, i.e. the pull-in range of synchronization is smaller than the pull-out range. The pulling function, i.e.

IET Seminar on High Efficiency Power Amplifier Design for Next Generation Wireless Applications, 2006
Load-pull systems are very versatile characterization tools for RF power devices. The measurement results enable the quick design of highly efficient and linear power amplifiers without the need of a device model but also allow verification of developed device models under realistic stimuli.

Chapter 3 describes active load-pull techniques, their design issues, and important related characteristics. The descriptions involve two aspects: the theoretical postulations of various active load-pull methods; and, then their respective designs and features, and associated practical issues normally encountered in their practical realizations ...

Scheduling design activities with a pull system approach
IEEE Transactions on Robotics and Automation, 1996The design process can be considered as a series of design phases. Each design phase can be further divided into number of design activities. In the network of design activities, the design activities generate information which is used by the succeeding activities.
