    Global manufacturing : study of company integration within a country : a thesis presented in partial fulfilment of the requirements for the degree of Master of Technology in Production Technology at Massey University
    (Massey University, 2004) Yusmira, Herwan
    A number of studies on Global Manufacturing Practices and the establishment of global company integration based on the similarity of practices among countries or regions have been conducted in the past. However, very few studies have been conducted on the integration of companies within a country. This study, using a survey approach, investigates an integration method based on Global Manufacturing Practices data collected from small and medium manufacturing companies in Indonesia. The development of successful joint ventures, integration, and other forms of collaboration depend on the ability to successfully integrate the production activities (Gyula Vastag, 1993). Global Manufacturing Practices developed by D). Clay Whybark, describe methods to examine the aspect of manufacturing activities based on the compatibility index (i.e. manufacturing practices) among participating companies around the world. The measurement of compatibility developed in his study is based on the data compiled by the Global Manufacturing Research Group (GMRG). Several comparisons, primarily based on statistical analysis, are helpful in understanding differences in manufacturing practices. Using the Global Manufacturing Practices survey, the study examines the participant perceptions of the manufacturing practices within their companies. The survey subjects are small and medium manufacturing firms (SMEs) from different regions of Indonesia. In addition to making general conclusion about manufacturing practices, the research proposes suggestions for development of integration based on measurements of the compatibility index of manufacturing practices relative to the Polman1 Politeknik Manufactur Bandung (Bandung Polytechnic for Manufacture), an Educational institution (see chapter 4). base region. The study evidence indicates the following major finding: • Hie participating companies indicated that a manufacturing activities database of Global Manufacturing Practices is an important knowledge resource and should be established on the basis of being clearly defined and accessible to all, including people outside the contributing companies. • To gain the most potential benefit, this data should be used for strategic planning prior to collaboration. The findings of the study suggest that a successful production activities integration process is dependent, to some degree, on the compatibility of manufacturing practices between collaborative parties. Further work, to confirm the suitability of the Compatibility Index for predicting actual compatibility, will be needed, but was judged to be beyond the scope of this thesis.

    Methods of representing the structure of complex industrial products on computer files, to facilitate planning, costing and related management tasks : a thesis presented in fulfilment of the requirements for the degree of Master of Technology in Manufacturing and Industrial Technology at Massey University
    (Massey University, 1992) Burns, Sara
    When the original concepts for the computerisation of product structures were developed in the late 1960's the available computer power was very limited. A modularisation technique was developed to address the situation in which a number of similar products were being manufactured. This technique tried to rationalise these products into family groups. Each member of the family differed from the others due to the possession of different features or options. However there was also a high degree of commonality to give the product membership of the family. Modularisation involved the identification of the options and features providing the variability. Those parts remaining tended to be common to all members of the family and became known as the common parts. Separate Bills of Material (BOMs) were set up for each of the identified options or features. Another BOM was set up for the common parts. The simple combination of the required options and/or features BOMs with the common parts BOM specified a product. Computer storage requirements and redundancy were reduced to a minimum. The Materials Requirements Planning (MRP) system could manipulate these option and feature BOMs to over plan product variability without over planning the parts common to all members. The modularisation philosophy had wide acceptance and is the foundation of MRP training. Modularisation, developed for MRP, is generally parts orientated. An unfortunate side effect tends to be the loss of product structure information. Most commercial software would list 6 resistors, Part No. 123, in the common parts BOM without concern as to where the resistors are fitted. This loss of product structure information can hide the fact that two products using these 6 resistors 'in common' are in fact different as they do not use the resistors in the same 6 places. Additional information must be consulted to enable the correct assembly of the 'common' portion of these products. The electronics industry is especially affected by this situation. This industry has changed considerably since the late 1960's. Product variability can be very high. Changes and enhancements are a constant factor in products having a relatively short life span. The modularisation technique does not have a good mechanism for the situation where an option itself has options or features. This situation can exist down a number of layers of the family tree structure of an electronics product. Maintenance of these BOMs is difficult. Where there are options within options the designers and production staff need to know the inter-relationship of parts between options to ensure accuracy, compatibility and plan assembly functions. The advent of computerised spreadsheets has made the maintenance of this type of product structure information easier. This matrix is another separate document which must be maintained and cross checked. It will inevitably differ from the BOMs periodically. This thesis develops a product structure Relational BOM based on the matrix for the family of products. The processing power of the 1990's computer is fully utilised to derive the common parts for any or all of the selected products of the family. All product structure information is retained and the inter-relationship of parts is highly visible. The physical maintenance of the BOMs is simple. The BOM serves all purposes without the need for supplementary information. It is fully integrated into the Sales Order Entry , MRP, Costing, Engineering Design and Computer Aided Manufacturing (CAM) systems. This technique has been proven by being the only system used in one Electronics Design and Manufacturing organisation for over 1 year without any major problems. As described in Section 1.6 user satisfaction has been high. The response of the users to the suggestion 'lets buy an "off the shelf" package' is very negative, as it would not incorporate this BOM system. Users have expressed the opinion that EXICOM could not continue, with present staffing levels, using the traditional BOM structure.
