TL;DR: In this paper, the authors describe a five-layer hierarchical production control model for the automated manufacturing research facility at the National Bureau of Standards (NBS), which is used as a test bed for the identification, design, and testing of standards for automated factories.

TL;DR: Nonhierarchical control architectures offer prospects of reduced complexity by localizing information and control, reducing software development costs, increasing maintanability and modifiability, and improving reliability.

TL;DR: An analytical model for the prediction of geometric error of a machine tool is presented and it is shown that the higher order terms of the expression make significant contributions to the predicted error.

TL;DR: In this paper, a methodology is proposed for the automated design and robotic assembly of modular fixturing systems based on the integration of state-of-the-art methodologies from several distinctly different disciplines.

TL;DR: An efficient computerized method for forming group technology part families using a goal programming based multiobjective clustering analysis with a group technology classification and coding system is presented.

TL;DR: Comparison with other techniques indicates that the pattern recognition approach has greater flexibility and typical advantages are the capability to introduce cost measures which reflect the relative importance of machines as well as the ability to represent the type of material flow being modeled.

TL;DR: A distributed microprocessor-based architecture is described and a two-level machine tool synchronization structure is presented, given in terms of Petri nets: a graphical-mathematical technique suitable for representing process parallelism and asynchronism for flexible control of machine tools in a job shop environment.

TL;DR: This paper shows how dummy transitions can be incorporated in a timed Petri net to model contingencies in the system such as machine or tool breakdown, quality deterioration, or production volume surge.

TL;DR: In this article, a system approach to task allocation has been taken that includes inventory of anticipated common tasks in manufacturing, design of products to be manufactured, allocation of tasks between humans and robots, and iterative improvement in product design.

TL;DR: In this article, a conceptual model of component accumulation in small-lot assembly systems and mathematica is presented that describe kit earliness, kit tardiness and in-process time for component inventory.

TL;DR: In this paper, a promising new approach to simultaneously obtain the solution to the machine parameter optimization and scheduling problems in n jobs and m machines manufacturing system is presented, based on the view that in order to optimally utilize the machine resources in a shop, the decision of allocating jobs to machines must be made simultaneously with the decision how a job should be processed on the machine to which it is assigned.

TL;DR: In this paper, two microcomputer based computer aided process planning systems are developed to assist small-to medium-sized companies implement automated process planning (APP), which is a variant process planning system used to manipulate a large manufacturing knowledge database.

TL;DR: In this paper, the realized cells for both prismatic and rotational parts and criteria for their technological and economical valuation are described, and computer supported simulation for system planning and scheduling optimization is demonstrated in different applications.

TL;DR: An integrated scale model of a flexible production line and an automated storage and retrieval system is described in this article, which is used for educational purposes as well as for physical simulation of new scheduling and control algorithms.

TL;DR: Fundamental aspects of models that might be used to design and/or manage operations in the flexible manufacturing environment are presented and demonstrated and appear to offer a viable means of conceptualizing transient operations and is supported by empirical justification.

TL;DR: An approach for modeling the transient performance of small-lot assembly lines is described; it can be applied by both manufacturing engineers and materials managers to unify decisions, thereby promoting effective performance.

TL;DR: An algorithm is developed for the automated conversion of wire frame data to solid geometric which would give the combined advantages of easy data input and the enormous descriptive power of solid geometric form.

TL;DR: SIMSHOP as mentioned in this paper is a FORTRAN-based discrete event simulator which can be used in the design and evaluation analysis of complex discrete parts batch manufacturing systems involving either functional or cellular layout configurations.

TL;DR: In this paper, the authors present two models for batching and capacity decisions applicable to manufacturing cells with metered flow, which use radically different assumptions concerning the supply of work to be processed in the cell and the removal of finished products.

TL;DR: In this article, a mathematical formulation for integrated production system planning is proposed, where the economic decision model integrates product selection, capacity planning, process planning, and facility layout, and the network structure of the material flow constraints facilitates the solution.

TL;DR: In this paper, the types of training programs that plants use to help their employees adapt to different types of CAM technologies are examined based on a national probability survey of manufacturing establishments, and the relationship of type of training to the type of CAM equipment in place is examined.

TL;DR: In this paper, the authors discuss the effects of different design factors on the performance of automatic assembly systems with tunnel-gated stations and present the analysis of a factorial experiment design based on the discrete event simulation results.

TL;DR: In this article, the authors discussed the application of this concept in a manufacturing environment and found that the material handling scheme in place significantly degraded the system performance, and alternative schemes were proposed to improve the performance of the facility.
