Determination of the optimum implementation plan for manufacturing technologies—The case of a helicopter fuselage
Journal of Munufacturing Systems Vol. 21/No. 6 2002
2000-2002 abstract and keyword index using a target optimum technology mix that yields the lowest recurring cost with a given probability. This target is determined assuming that all candidate technologies are available immediately and are applicable over the entire structure. Then, the applicability of the candidate technologies as a function of time is determined, and the non-recurring cost associated with process and product development is calculated as a function of time. The applicability and non-recurring cost are used to generate time-dependent implementation paths that reach the target technology mix with lowest investment or maximum yearly recurring cost savings. Keywords: Manufacturing Technologies, Technology Technology Investment Scenarios, Implementation, Cost, Technology Recurring Cost, Non-Recurring Applicability
research is based on a project supported by the Amarillo National Resource Center for Plutonium. A computerized prototype decision-making model is developed based on the proposed methodology. The research result can be extended to the recycling process of all kinds of electromechanical scraps. Potentially, the proposed methodology can be adopted for assessing various recycling alternatives to provide environmentally friendly solutions. Keywords: Electronics Recycling, Environmental Impact Assessment, Fuzzy Membership Function, Analytic Hierarchy Process Development of a Compliance Tester for Assessing and Reducing the Static Compliance of Fixture- Workpiece Systems, Reha Haymanali, Edward C. De Meter, Martin W. Trethewey, ~19, n2, 2000, pp 1OS-120
A critical attribute of a fixture-workpiece system is the static compliance of the workpiece surfaces to be machined. This paper describes a diagnostic tool that can be used by a tool engineer to experimentally assess and reduce the static compliance imparted onto a workpiece by a machining fixture. This tool can be used for the troubleshooting of dedicated fixtures suspected of providing inadequate support and/or the assessment and optimization of modular fixtures during buildup. This paper describes the underlying theory behind the design of the tester. Provided is an overview of the tester’s hardware and software functions, including the details of a software module used to determine the minimum number and placement of support clamps that must be added to a fixture to ensure that workpiece compliance does not exceed a specified threshold. Last, the paper will describe a set of experiments that was used to verify the support-clamp placement module. Keywords: Fixturing, Compliance Testing, Fixture Optimization

2000, pp134-148 The manufacturing function can be a formidable weapon to achieve competitive superiority. Through three case studies, this paper observes the manufacturing strategy practices in select Indian organizations. The common aspects and differences between the example organizations are highlighted. A model is proposed linking the manufacturing competitive priorities and the action plan pursued by these firms.

Journal of Manufacturing Systems Volume 19, Number 3,200O Computer-Controlled Lapping System for Granite Surface Plates, Jiexin Wang, Bi Zhang, Binyuan Xue, ~19, n3,2000,
pp149-155 Granite surface plates are traditionally finished by hand lapping, which is time consuming, strenuous, and costly. Surface quality and accuracies of such plates depend largely on the experience and skill level of the operator. In this study, a computer-controlled system is developed for ultra-precision lapping of granite surface plates. The system can easily achieve a high lapping efficiency and high flatness accuracy due to its capability of on-line measurement of flatness, optimization of the lapping process, and automation of the lapping operation. The system has been successfully applied to a number of granite surface plates, and the results show that a flatness
Determination of the Optimum Implementation Plan for Manufacturing Technologies-The Case of a Helicopter Fuselage, Christos Kassapoglou, ~19, n2, 2000, pp 121- 133
This paper presents an approach to determine manufacturing technology implementation scenarios as a fimction of time. The optimum paths from the point of view of minimum investment or maximum recurring cost savings are determined and their advantages and disadvantages are discussed. The logic and the results of a software code created to determine these paths are described. Hybrid scenarios that compromise between the two cases of minimum investment and maximum recurring cost savings are also presented. The approach is based on
