TL;DR: This document presents dynamic models of production at two levels of details, and extends existing activity analysis models for detailed networks to include the common situation of significant, finite processing times at each activity.
Abstract: : A decision support system for the management of a production organization must include an explicit model or models of the production system When the organization faces a dynamic environment, dynamic models are most appropriate The document presents dynamic models of production at two levels of details First, it extends existing activity analysis models for detailed networks to include the common situation of significant, finite processing times at each activity This extension shows that dynamic activity analysis models require different indexing functions for the application of labor and machine services and for the application of raw materials and intermediate products It is demonstrated that the improved accuracy of this model is very significant when the typical processing time in the system exceeds the planning time-grid intervals The importance of this development is in the identification of the underlying assumptions and range of appropriateness of the existing models and in the extension of these models to non-instantaneous production processes Additional keywords: operations research; scheduling heuristics; dynamic linear activity analysis; models; mathematical programming; industrial engineering

TL;DR: It is asserted that data base management technology supporting engineering/manufacturing in a heterogeneous hardware/data base management system environment should be applied to meeting the space station life cycle requirements.
Abstract: General capabilities of data base management technology are described. Information requirements posed by the space station life cycle are discussed, and it is asserted that data base management technology supporting engineering/manufacturing in a heterogeneous hardware/data base management system environment should be applied to meeting these requirements. Today's commercial systems do not satisfy all of these requirements. The features of an R&D data base management system being developed to investigate data base management in the engineering/manufacturing environment are discussed. Features of this system represent only a partial solution to space station requirements. Areas where this system should be extended to meet full space station information management requirements are discussed.
TL;DR: In the last decade, production engineering has changed extensively and today as many production engineers are found in the non-metal cutting industries as in the old traditional metal cutting ones as discussed by the authors.
Abstract: Production engineering has changed extensively in the last decade and today as many production engineers are found in the non‐metal cutting industries as in the old traditional metal cutting ones. Even metal cutting techniques have changed with the introduction of computer‐controlled machine tools, computer‐aided design, robotics and the semi‐automated factory.

TL;DR: The laser is being increasingly used as a manufacturing tool in the fabrication of aircraft gas turbine engine components and is employed for a variety of manufacturing tasks including welding, cutting, hole drilling, surface alloying, and marking of parts for identification as mentioned in this paper.
Abstract: The laser is being increasingly used as a manufacturing tool in the fabrication of aircraft gas turbine engine components. Both solid-state pulsed and gas continuous-wave lasers are employed for a variety of manufacturing tasks including welding, cutting, hole drilling, surface alloying, and marking of parts for identification. In these applications, the laser provides increased productivity and reduced cost compared to conventional methods. Examples of specific uses of the laser in gas turbine fabrication are described along with the benefits achieved. Metallurgical effects associated with various laser processes are also discussed.Copyright © 1985 by ASME

TL;DR: In this paper, a "miniline" concept for solving technical problems on manufacturing lines has been successfully used on several different products and the key to this success is using fundamental science with the most advanced methods of characterization possible to analyze pieces of real product processes.
Abstract: A "miniline" concept for solving technical problems on manufacturing lines has been successfully used on several different products. Key to this success is using fundamental science with the most advanced methods of characterization possible to analyze pieces of real product processes. Industry or university scientists simulate the production process closely by using sophisticated analytical tools appropriately · instrumented. This results in fundamental understanding of the sequence of events occurring in each process step in the production line. Understanding leads to better definition of process windows and better control of the process. Parts may be Processed on the production line or on the laboratory equipment for direct comparison of particular production steps. Teamwork among researchers and an interdisciplinary group of development and manufacturing engineers is a key ingredient to success.
