Feeding Speed

The purpose of this paper is to improve line productivity using line balancing technique and a reduction of work variation using an automated part feeder. This is due to the fact that the conventional assembly line manually feeds a part on to the production line by a worker. The feeding cycle is not constant and varies from time to time. Thus, the production rate is not constant and varied by the worker feeding speed. In addition, the assembly line itself does not fully balance. The operation time of each station is not well designed; as a result, all of the stations but the bottle-neck one experience an idle time. The balance efficiency is only at 40.33 percent which means that 59.67 percent of the total production time is balanced delay. Once the automated feeding machine which a buffer is designed and implemented. The cycle time can be set at 6 sec. and with the line balance technique the operator can be reduced from 11 to 9 persons. As a result, the productivity is substantially increasing around 138 percent and the new balance efficiency is 85.12 percent.

This research objective is to improve the productivity of cookware assembly line by means of time and distance reductions. The motion study and line balancing techniques were applied to the entire assembly operations. A bottle neck was identified to where the operation with inadequate machine layout and workplace organization, including the unbalanced workloads. The new workplace layout and new working method for operators were designed and implemented as well as balancing the assembly line. Specifically, the conveyor speed and duration between the consecutive workpieces in the production line were adjusted to 0.10 m/s and 50 cm, respectively. The number of operators needed in the process can be reduced from 14 persons to 11 persons. The cycle time for assembling process is decreased from 12 to 5 second.

This paper applies the methods of Work Study to a certain hydraulic component company. We apply the work measurement method to measure the work time of various stations of assembly lines, and to find out both the bottle neck stations and the superfluous capability stations effecting on the line assembly capability. Basing on the principle of ECRS (Eliminate, Combine, Rearrange, Simple) and the line balancing theory, this paper provides the line balancing schema, including the improvement of the existing equipment, the reallocation of the work content for relative stations, the adjustment of the equipment and workers of some stations, the reduction of machine working time of some stations and the change of assembly line layout etc. After being improved, the work time of the bottle neck and other processes are controlled near the Taking Time. Comparing with the former assembly line, the production capability of assembly line improved up 45.6% and workshop condition is also improved.

For a large number of uncertainties such as suppliers, customer demand and different external uncertainties, as well as workers, machines, environment and other internal uncertainties, they affects the mixed-model assembly line balancing. And these uncertainties can be turned into the changes of demand, operation time and workstation availability, which are relevant to mixed-model assembly line balancing. By solving the three factors influence on the balancing, these uncertainties influence is processed. This paper provides a way to process uncertainties influence on the mixed-model assembly line balancing.

Through the comparative analysis, the features of the mass customization assembly line are obtained. The corresponding genetic algorithm is designed with the total idle time and overloading time of the minimized assembly line as the target function, which is used to resolve the distribution problems of the operation elements in mass customization assembly line. The improved genetic operators can heighten the overall optimal solution ability of genetic algorithm convergence. The calculated examples indicate that this algorithm is the effective method for seeking out solution to the problems of operation elements in the mass customization assembly line.

Line balancing adalah suatu usaha mengatur lintasan produksi dengan tujuan merencanakan keseimbangan lintasan stasiun kerja (work station) pada tingkat shop floor, guna memperoleh tingkat efisiensi kerja yang tinggi. Proses pembuatan T-Shirt di PT. Caladi Lima Sembilan (C-59) memiliki proses operasi yang tidak seimbang, sehingga terjadi penumpukan barang setengah jadi pada suatu stasiun kerja dan adanya waktu menganggur (idle time) pada suatu proses operasi karena adanya antrian barang setengah jadi pada suatu mesin (bottle neck). Metode Line Balancing yang digunakan adalah metode Hegelson-Birnie yang didasarkan pada prioritas bobot posisi setiap operasi/elemen kerja dan metode Killbridge-Wester yang didasarkan pada pembagian wilayah. Kedua metode-metode yang digunakan sama-sama memberikan  hasil yang optimal dalam mengatasi persoalan line balancing. Pada Metode Hegelson-Birnie dengan waktu siklus 30 detik diperoleh rata-rata efisiensi sebesar 93,33% dengan idle time 16 detik dan balance delay sebesar 6,67%, selain itu adanya pengurangan jumlah stasiun kerja dari 16 stasiun kerja menjadi 8 stasiun kerja. Sedangkan pada Metode Killbridge-Wester dengan waktu siklus 40 detik diperoleh rata-rata efisiensi sebesar 80,00% dengan idle time 56 detik dan balance delay sebesar 20%, selain itu adanya pengurangan jumlah stasiun kerja dari 16 stasiun kerja menjadi 7 stasiun kerja. Dari perbandingan kedua metode tersebut yang merupakan solusi terbaik di dalam penerapan metoda line balancing pada pembuatan T-Shirt di PT. Caladi Lima Sembilan (C-59) adalah metode Hegelson-Birnie.
