Abstract

Syarikat pembuatan bukan sahaja perlu memenuhi keperluan pelanggan seperti penghantaran yang menepati masa tetapi juga perlu memenuhi keperluannya seperti penggunaan mesin yang tinggi dan tahap kerja separa siap yang minimum. Bagi mencapai matlamat ini, syarikat perlu menggunakan strategi yang sesuai. Penggunaan strategi yang sesuai dapat memperbaiki kemampuan syarikat pembuatan untuk memenuhi kehendak pelanggan dan juga kehendak syarikat pembuatan. Kajian ini mengenal pasti lima strategi yang membolehkan bengkel kerja menjadi fleksibel. Kelima–lima strategi ini merangkumi strategi asas yang melibatkan satu set lengkap mesin–mesin satu operasi hingga ke mesin–mesin berbilang operasi. Setiap strategi dinilai dan satu garis panduan dicadangkan. Hasil kajian menunjukkan bahawa strategi penduaan ialah yang terbaik jika kriteria prestasi yang dikehendaki ialah kelewatan dan kerja separa siap. Tetapi jika kriteria prestasi yang dikehendaki ialah tahap penggunaan mesin, maka strategi penggantian ialah yang terbaik. Kata kunci: Ukuran prestasi, bengkel kerja, strategi pembuatan Manufacturing companies are required to fulfill customer’s driven imperatives such as on time delivery as well its own requirements such as high machine utilisation and low work in process. In order to achieve these, manufacturers need to adopt the right manufacturing strategy. Selecting the right manufacturing strategies will improve its capability to meet its customers demand as well as its ovvn limitations. This research identifies five strategies that a job shop may adopt to achieve flexibility in meeting demand. The five strategies ranges from the basic strategy of having a complete set of single–operation machines to flexible multi–operation machines. Each strategy is evaluated and a set of guideline is proposed. The results show that when job tardiness and work–in–process is the performance criteria, the duplication strategy is the best. However, if the performance criteria is machine utilisation, then the best strategy is the replacement strategy. Key words: Performance measures, job shop, manufacturing strategy
