CIM Strategy And Strategic Management: An MIS Perspective

This study provides an overview of Computer-Integrated Manufacturing in a conceptual and managerial context, and analyzes the organizational structure and managerial approaches required for successful CIM. CIM is considered as the (vertical) integration of computerized manufacturing systems at the shop floor with Management Information Systems, and as the (horizontal) integration of functional areas from design, manufacturing to business functions. This implies an integrated, company-wide, MIS approach toward CIM rather than a traditional and functional attitude. In this context, the organizational structure that fits CIM technology will be analyzed.

Diastereoselective Access to the Spirotetronate Subunit of the Quartromicins

The agalacto-spirotetronate B subunit of quartromicins was synthesized in a predictible manner, following the Claisen-Ireland/metathesis approach (CIM strategy). Ene-yne ring-closure and selective mismatch Sharpless dihydroxylation are discussed as key steps, allowing an efficient approach to these structures.

CIM strategies and the shop coordination system

This paper discusses how a CIM strategy can, and should, be developed and how the shop coordination system can be a key component in achieving that strategy. The discussion on CIM centers on the need for the business strategy to drive the manufacturing strategy and the manufacturing strategy to drive the CIM strategy. The discussion on the shop coordination system details how this system may be specified and designed to be a cornerstone of the CIM strategy and how this system can achieve specific goals of the business strategy. The shop coordination system is defined in relation to the CIM strategy.

Teamwork and flexibility priorities for Jaguar

Examines the CIM strategy being implemented by Jaguar Cars as an attempt at future‐proofing its manufacturing control systems. Discusses the assembly line hardware, monitoring system, scheduling, information displays, supervision maintenance, and how CIM is assisting Jaguar′s total quality programme. surmises that the combination of hardware and software will allow steady building on existing facilities as well as coping better with new model introduction.

A management and control architecture for factory-floor systems: from concept to reality

Abstract This paper introduces MMCS, :a multi-level management and control architecture for factory-floor CIM systems. The thrust of the paper is that while a generic (software) architecture is a necessary prerequisite for designing and implementing flexible CIM systems, its successful application is dependent on an underlying CIM strategy and conditioned by factors specific to a given manufacturing environment. The utility of MMCS is demonstrated through reference to a real system that was successfully implemented during 1987 and 1988 in the food processing industry.

NC programming and dynamic simulation based on solid models in a CIM strategy

The growing performance of modern and flexible manufacturing installations necessitates better planning and execution strategies and the use of processsb simulation in the production process planning stage. The economic efficiency of CAD systems working on the basis of solid models depends to a large degree on one question: to what extent can computer-internal models be employed for tasks of EDP-supported planning and manufacturing in the context of a CIM strategy? On main topic is the automatic generation of control information for the machining of cubic parts or numerically controlled manufacturing installations. Here, the solid modeling system COMPAC provides a number of functions as application modules: • Workpiece, tools, chucking equipment and machine tools can be interactively configured. This is a prerequisite for the generation of models for off-line programming and for dynamic simulation of the cutter locations. The reference points of the objects are also determined in this process. • Programming is carried out in the graphic-interactive dialog on the basis of computer-internal representations of the finished part and raw part, taking into consideration the chucking equipment. • The selection of machinable surfaces is supported by the system; surfaces are shown in color. • Functions for the automatic path segmentation and the determination of milling cycles are available. • The NC control information is generated and displayed according to DIN 66025. • The programmed paths can be verified graphically. The surface to be machined is displayed in color. The surface traversed by the front surface of the milling tool is shown in a different color. Common areas are thus shown in a mixed color so that visual control of the machined zone is possible. • For the graphic-dynamic simulation of NC control information, a 3D vector-refresh workstation from Evans & Sutherland is employed. On this workstation the NC code can also be corrected.

CIM—the technology's not the real problem!

There are no universal solutions or standard procedures for computer integrated manufacturing; rather it is what each company makes of it. This paper outlines ideas from the development of a CIM strategy at Mars Electronics, and argues that success in implementation depends less on the technology, which is generally already in existence, than on management commitment and a clear vision of the company's future.

Computer integrated manufacturing

CADCAM alone is not CIM, but engineering data lies at the heart of CIM. This article discusses today's business challenges, the need for integration and one key element of CIM - the engineering database. Finally, the financial implications and the necessary steps to implementation of a company-wide CIM strategy are described.
