15 Dec 1985TL;DR: The manager who does not recognize and understand the forces which should affect and are affected by his decisions has little hope of effectively discharging the responsibilities of a managerial position.
Abstract: INTRODUCTION 5. Model verification 6. Model validation Effective execution of managerial responsibility is a perplexing task of ever increasing complexity. This is the result of unpredictable world, national and local economies, the pervasive impact of federal and state regulation, the capricious nature of the consuming public and the relentless and accelerating advance of modern. technology. The contribution of each of these elements of business life has led to the perceived need for larger and more complicated organizational structures to effectively carry on business activity. Consequently the manager is forced to recognize and understand the interaction of an increasing number of components within his own organization and its environment. With that recognition and understanding effective management is certainly not assurred. But the manager who does not recognize and understand the forces which should affect and are affected by his decisions has little hope of effectively discharging the responsibilities of a managerial position.

TL;DR: In this paper, the performance of a large generator under abnormal operating conditions through physical modeling and simulation is investigated. But the authors focus on the performance analysis of a single generator and do not consider the effects of different operating conditions on the generator.
Abstract: Micromachines are small machines specially designed so that their parameters, on a per unit basis, are similar to those of large generators in power systems, and they are widely used to study the performance of these large machines under abnormal operating conditions through physical modeling and simulation.

TL;DR: Improved Optical Detection System (IODS) as discussed by the authors is a set of electro-optical sensor simulation models integrated into an interactive, userfriendly software package designed for use in modeling and simulation of EOS systems and mosaic focal plane arrays.
Abstract: A set of electro-optical sensor simulation models is integrated into an interactive, userfriendly software package designed for use in modeling and simulation of electro-optical sensor systems and mosaic focal plane arrays. The software system, Improved Optical Detection System (IODS), includes modules for image and signal generation, image degradation due to optical system and environmental MTF characteristics, detector spectral, temporal and spatial frequency response, signal modulators, and processing electronics transfer function characteristics. The software system is currently utilized for beam diagnostics, surveillance, and remote sensing applications.
