This paper compares the performance of Jaccard's similarity coefficient with the producti on data-based simi 1arity coeffi­ cient. A number of machine-component charts taken from the literature or randomly generated are used to form machine-component groups. Then, the sum of intercellular and intracellular material handling costs for each machine-component group is calculated and used as a basi...

A recent discovery concerning the importance of hadron production in space radiation is that pions can contribute up to twenty percent of the dose from galactic cosmic ray interactions (S. Aghara, S. Blattnig, J. Norbury, R. Singleterry, Nuclear Instruments and Methods, Vol. 267, 2009, p. 1115). Although the contribution for dose equivalent will be smaller, the dose contribution could be import...

Starting from discrete event simulations based on sampled data we simulate the interplay between product density and flux. Data-fitting helps to determine the right parameters for clearing functions to close first and second order conservation laws. For the first order case well-known relations from M/M/1-queuing theory can be reproduced and numerically extended to transient behavior. To includ...

The production of accurate, digital trail representations is a necessary component of map making and trail user simulation. Typically, land managers, recreationalists and those who study trail use are interested not in a single trail but in an area which contains a complex network of trails and roads. GPS receivers facilitate the capture of accurate trail and road data. When used to extract a s...

This paper investigates the optimization problem of multi-product aggregate production planning (APP) with fuzzy data. From a comprehensive viewpoint of conserving the fuzziness of input information, this paper proposes a method that can completely describe the membership function of the performance measure. The idea is based on the well-known Zadeh’s extension principle which plays an importan...

This paper introduces a new data set for the analysis of productivity in U.S. manufacturing. It consists of data on production and input levels when the plants in an industry operate at capacity. The estimates are consistent with those obtained using data on actual operations from the ASM. As an application, I use this data to estimate the rate of growth of technological change that is embodied...

We describe the design and operational experience of the ATLAS production system as implemented for execution on Grid3 resources. The execution environment consisted of a number of grid-based tools: Pacman for installation of VDT-based Grid3 services and ATLAS software releases, the Capone execution service built from the Chimera/Pegasus virtual data system for directed acyclic graph (DAG) gene...

Steel is one of the most important materials for building a wide variety of products. The downside of a wide usage of steel is the energy-intensive production process and the high output of carbon dioxide. In our efforts to make the production of steel more sustainable, we focus on one step of the steel production only, the conversion of raw iron to high quality steel in a Basic Oxygen Furnace ...

This study is an exploration of areas pertaining to the use of production data in non-production environments. During the software development lifecycle, non-production environments are used to serve various purposes to include unit, component, integration, system, user acceptance, performance and configuration testing. Organisations and third parties have been and are continuing to use copies ...
