The tasks of planning and scheduiing in manufacturing have evolved from simplistic Material Requirements Planning systems to today's sophisticated Advanced Planning and Scheduling systems. While planning is concerned with the long-range determination of what needs to be manufactured, typically over a relatively long time period, scheduling is the task of deciding how that manufachlring is to be accomplished, typically over a relatively short time period. Simulation is well suited to the scheduling task since it can handle as much detail as is necessary to capture the subtleties of the manufacturing process. It is desirable for a simulation-based scheduling function to be integrated with an Enterprise Resource Planning system, which maintains the system data suitable for driving a simulation of the current system load and thereby producing a feasible schedule. This paper describes such an integrated system and the role of simulation within it.

We dedicate this book to two people who changed addiction science for the better: Lenka Čablová (1986-2016) and Griffith Edwards (1928Edwards ( -2012 Contents Foreword to the Third EditionThe health and social burden attributable to psychoactive substance use is enormous. Alcohol, tobacco and illicit drug use taken together are by far the most important preventable risk factors to a population's health. According to the latest WHO estimates, the harmful use of alcohol alone results in around 3.3 million deaths every year. With rapid social and cultural changes taking place in many countries, alcohol and drug use are becoming increasingly embedded in social matrices, often with strong commercial forces playing a role in promoting the use of legal intoxicating and dependence-producing substances. A number of jurisdictions have undertaken major changes in the regulation of psychoactive substances controlled under international drug treaties. New Psychoactive Substances (NPS), with their health effects and distribution channels, present new challenges for public health authorities. Debates around alcohol and drugs are at the forefront of social policy processes in many countries, with significant variations in societal responses. Unfortunately, these debates are often not based on solid data or research evidence, and in many cases the relevant data simply does not exist. Significant caveats exist in the evaluation of existing policy responses and policy changes made in different jurisdictions. There is an urgent need to strengthen the evidence base for the development of adequate program and policy responses to substance use and substance use disorders at different levels. It is difficult to overestimate the role of research and scientific data in shaping policy and program responses at all scales, from local communities to the x Foreword to the Third Edition international level. A consistent and common issue is the lack of sufficient resources for research on substance use and substance use disorders, and very often even those resources available are not utilized to their maximum potential. One of the biggest problems is when investment in research does not result in the publication and dissemination of results, preferably in peer-reviewed journals. This is a particularly prevalent issue in less-resourced countries where opportunities for publishing results of research on substance use and substance use disorders are limited, and where no specialized journals on addiction exist.The third edition of Publishing Addiction Science: A Guide for the Perplexed is an important resource for researchers around the world, especially for those who work in low and middle-income countries. It is hoped that this resource will facilitate the dissemination of new data and ...
SLAM 11 is a general-purpose language which has been used since 1979 to model a wide variety of systems: manufacturing operations, transportation systems, communication networks, computer systems, military operations and material handling systems, just to name a few. Experience with these applications, plus development in simulation research, have led to the expansion of the language throughout its lifetime. The ease of using the SLAM I1 language was greatly increased by the introduction of SLAMSYSTEM in 1988; SLAMSYSTEM Version 4.0 isthemostrecentrelease,arrivingin 1993. SLAMSYSTEM is an integrated simulation system based on the Microsoft Windows interface (under MS-DOS) or the OS/2 Presentation Manager. This tutorial will demonstrate the process of building, analyzing, and presenting SLAM I1 simulation models using SLAMSYSTEM.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
