Book Synopsis Experiments in Variable-resolution Combat Modeling by : Richard John Hillestad
Download or read book Experiments in Variable-resolution Combat Modeling written by Richard John Hillestad and published by . This book was released on 1993 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Note examines the differences in combat outcomes predicted by models of different resolution applied to identical combat situations. First, hypothetical combat situations are posed, then several models of varying degrees of resolution in the spatial representation, aggregation of forces, and time step are used to predict losses and battle winners. Both stochastic and deterministic simulations are used. Comparison of outcomes provides important insights into the problems of aggregation. Observations from this set of experiments are as follows. Intuition regarding outcomes, causes, and effects is frequently wrong, leading to bad approximations in the aggregate. Scaling for different levels of resolution is possible, but a method of predicting the appropriate scaling technique and factors has not been found. The differences in outcomes between stochastic and deterministic models are most pronounced in the 'fair-fight' regime, in which the force balance (accounting for situational factors) is almost even. Because defense analysis frequently operates in this regime (getting just enough force to a theater or because constrained defense budget allocations may not permit overwhelming odds), this implies that great care should be taken to understand the possible variance in outcomes.

Available in PDF, EPUB and Kindle. Book excerpt: Operations Research (OR) emerged in an effort to improve the effectiveness of newly inducted weapons and equipment during World War II. While rapid growth ofOR led to its becoming an important aid to decision making in all sectors including defense, its contribution in defense remained largely confined to classified reports. Very few books dealing with applications of quantitative decision making techniques in military have been published presumably due to limited availability ofrelevant information. The situation changed rapidly during the last few years. The recognition of the subject of Military Operations Research (MOR) gave tremendous boost to its development. Books and journals on MOR started appearing. The number of sessions on MOR at national and international conferences also registered an increase. The volume of teaching, training and research activities in the field of MOR at military schools and non-military schools enhanced considerably. Military executives and commanders started taking increasing interest in getting scientific answers to questions pertaining to weapon acquisition, threat perception and quantification, assessment of damage or casualties, evaluation of chance of winning a battle, force mix, deployment and targeting of weapons against enemy targets, war games and scenario evaluation. Most of these problems were being tackled on the basis of intuition, judgment and experience or analysis under very simple assumptions. In an increasingly sophisticated and complex defense scenario resulting in advances in equipment and communications, the need for supplementing these practices by scientific research in MOR became imperative.

Book excerpt: Military conflicts, particularly land combat, possess thecharacteristics of complex adaptive systems: combat forces arecomposed of a large number of nonlinearly interacting parts and areorganized in a dynamic command-and-control network; local action, which often appears disordered, self-organizes into long-range order;military conflicts, by their nature, proceed far from equilibrium;military forces adapt to a changing combat environment; and there isno master voice that dictates the actions of every soldier (i

Book Synopsis Implications of Modern Decision Science for Military Decision-Support Systems by : Paul K. Davis
Download or read book Implications of Modern Decision Science for Military Decision-Support Systems written by Paul K. Davis and published by Rand Corporation. This book was released on 2005-09-14 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: A selective review of modern decision science and implications for decision-support systems. The study suggests ways to synthesize lessons from research on heuristics and biases with those from "naturalistic research." It also discusses modern tools, such as increasingly realistic simulations, multiresolution modeling, and exploratory analysis, which can assist decisionmakers in choosing strategies that are flexible, adaptive, and robust.

Book Synopsis An Analysis of Alternative Methods to Conduct High-Resolution Activities in a Variable-Resolution Simulation by : Paula J. Warhola
Download or read book An Analysis of Alternative Methods to Conduct High-Resolution Activities in a Variable-Resolution Simulation written by Paula J. Warhola and published by . This book was released on 1997-09 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study analyzes an original hybrid combat simulation for possible use as the underlying support model for the Joint Warfare Systems (JWARS) analytical simulation. The model employs a fixed increment time advance mechanism but represents individual entities vice aggregated units. Results from an otherwise identical model using a next event time advance mechanism provide a baseline for comparison. The hybrid, using a longer time increment, runs faster than the next event model but produces unacceptable results. The hybrid, using a smaller time increment, more closely approximates the next event model but takes longer to run.

Book Synopsis Cutting Some Trees to See the Forest by : Richard John Hillestad
Download or read book Cutting Some Trees to See the Forest written by Richard John Hillestad and published by . This book was released on 1993 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most models of air and land combat use schemes of aggregation and disaggregation in representing combat systems, in spatial configuration, and in depicting the progress of a battle. For example, the use of firepower scores is an extreme case of aggregation of weapons into a single measure. Combining like systems into weapons categories-partial aggregation-is a common approach to representing a large number of aircraft or ground weapon types. This report explores different approaches to aggregation and what is known theoretically about aggregation and disaggregation in Lanchester combat models that in two dimensions are commonly called square-law models. It defines requirements for consistency between aggregate and higher-dimensioned models of this type. Some important conclusions are that aggregation should take into account the specific capabilities of the opponent (raising concern about many 'scored' approaches that attempt to evaluate force components in isolation), and that partial aggregation (grouping 'like' systems) and disaggregation of previously aggregated results can be done consistently only when certain restrictions on the relative attrition capabilities of weapon systems hold. When this is the case, specific nonarbitrary weightings can be determined for the partial aggregations.
