Vibration related outages due to an unbalance in rotating equipment have been a historic problem in the power generation industry and have resulted in increased plant operating costs. Until recently, the only means for solving these vibration problems was to perform manual balancing on the rotating equipment. Active balancing systems have been used in other industrial processing applications, on ID/FD fans, compressors, and turbines, for many years. Further developments in active balancing capabilities have positioned these systems to cover the broad range of applications in the power generation industry today.

This paper applied stopwatch to measure the work time of workstations on lamp assembling line. It studied issues effecting line production capability such as bottleneck workstations and superfluous capability. To overcome these shortcomings this paper suggests new line balancing schema. The schema includes reallocation of the work content, adjustment of the equipment and workers of each workstation. This improvement saves extra work shifts and reduces labor cost.

Produktiviti merupakan sesuatu yang amat penting bagi sesebuah organisasi, terutamanya bagi sektor pembuatan ke arah meningkatkan keuntungan untuk memajukan syarikat. Kertas kerja ini melaporkan satu kajian kes bagi pembaikan kerja di sebuah syarikat pengeluaran kereta. Kajian kes ini terbahagi kepada dua bahagian iaitu mengenalpasti masalah di lini pemasangan utama dan mencadangkan pembaikan ke arah meningkatkan kecekapan sistem yang sedia ada. Berdasarkan kepada pemerhatian dan juga data yang dipungut, kerja tergendala di lini pengeluaran adalah merupakan masalah utama. Ia disebabkan oleh sistem pengangkutan bahan yang kurangcekap dan pembahagian kerja yang tidak seimbang. Teknik pembaikan kerja digunakan untuk mencari penyelesaian yang terbaik bagi mengatasi masalah di atas. Kemudian, kaedah keseimbangan lini digunakan untuk meminimumkan masa melahu pada setiap stesen kerja. Untuk mengesahkan keputusan daripada alternatif-alternatif yang dicadangkan, simulasi dengan menggunakan perisian Witness telah digunakan. Satu alternatif terbaik dipilih berdasarkan kepada keputusan daripada simulasi dan juga justifikasi kos. Akhir sekali, perancangan sumber dijalankan ke arah memenuhi permintaan dan juga memaksimumkan penggunaan sumber. Daripada keputusan simulasi bagi sistem yang dicadangkan, menunjukkan bahawa produktiviti meningkat sebanyak tiga kali ganda berbanding dengan sistem yang sediada. Walaubagaimanapun, keputusan ini adalah berdasarkan kepada beberapa andaian yang dibuat semasa projek dijalankan. Kata kunci: Kerja dalam proses (tergendala) di lini pengeluaran; Kerja dalam proses (tergendala) di luar lini pengeluaran; pembaikan kaedah; keseimbangan lini; simulasi; justifikasi kos; perancangan sumber Productivity has been identified as an important role in any organization, especially for manufacturing sectors to gain more profit that leads to prosperity. This paper reports a work improvement project in a car manufacturing company. It involves problem identification at the metal finish line and proposing recommendation to improve the current situation more efficiently. Based on the observation and data online work–in–progress (WIP) has been identified as a major problem and this is caused by the insufficient movements due to material handlings and unbalanced workload. Method improvement technique is used to determine the best method of carrying out a task in order to eliminate the unnecessary movements. Then, line–balancing technique is used to minimize the idle time at every station or the percentage of line balance loss (LBL). In order to verify the results that were obtained from the generated line–balancing alternative, Witness simulation package is used to obtain the output. One effective alternative is chosen based on the results obtained from the simulation and cost justification. Then, a proper planning is suggested to maximize the resource utilization at the metal finish line. Simulation results showed that productivity increases roughly three times higher than the current situation. However, the results were obtained based on several assumptions that had been made during carry out this project. Key words: On-line Work-In-Progress (WIP); Off-line Work-In-Progress (WIP); method improvement; line balancing; simulation; cost justification; resource planning and allocation

Production Line Balancing (PLB) is the technique of assigning the operations to workstations in such a way that the assignment minimizes the idle time between workstations. PLB aims to equator the workload in each workstation to assure maximum production flow. By adding machine in specific configurations is one treatment which leads to this leveling in workload. This research studies the different efficiencies of the added machine and the effect of these efficiencies on line balancing to select the machine with suitable efficiency. This will be led to reduce the idle time between workstations and increasing production flow. The work time considered as the efficiency criterion for this case study. The study has been implemented on a dumb truck production line and resulted in increasing the line efficiency to 81.7%.
