Assembly line balancing has been a focus of interest in Industrial Engineering for the last few years. Assembly line balancing is the problem of assigning tasks to workstations by optimizing a performance measure while satisfying precedence relations between tasks and cycle time restrictions. Line balancing is an important feature in ensuring that a production line is efficient and producing at its optimum. The process of Line balancing attempts to equalize the work load on each workstation of the production line. Mixed model assembly lines are increasing in many industries to achieve the higher production rate. This study deals with mixed-model assembly line balancing and uses Yamazumi chart to break down the work element in to the value added & Non-value added part to reduce the waste & increase the productivity.

With the continuous upgrading of the manufacturing system, the assembly line balancing problem (ALBP) is gradually complicated, and the researches are constantly deepened in the application theory and solution methods. In order to clarify the research direction and development status of assembly line balancing, 89 articles are read and studied. We classify ALBPs to construct the network structure of research from horizontal classification and vertical thinking. The ALBP framework is horizontally given according to the number of models (i.e. the number of products), the layout shape of the assembly line, and the data of task time. The “seven steps for scientific paper” is vertically proposed according to the research steps to comb the research path of scientific and technological literature. The horizontal and vertical extension crosses and constructs the network structure of the ALBP. Any horizontal problem intersects with any step of the vertical “seven steps for scientific paper” to form a research point. We analyze 89 articles according to the development path from the straight line to U-shaped line and then to two-sided U-shaped/parallel U-shaped assembly line, summarize the research algorithm of assembly line balance and count the number of articles, and point out the latest research direction and algorithm development trend of assembly line balance.

PT XYZ merupakan salah satu perusahaan yang bergerak di bidang industri mebel. Masalah yang dihadapi perusahaan adalah adanya ketidakseimbangan di lintasan produksi akibat ketidakmerataan pembagian beban kerja di setiap stasiun kerja. Hal ini menyebabkan performansi keseimbangan lintasan (line performance) menjadi kurang baik. Untuk menyelesaikan permasalahan ini perlu dilakukan penyeimbangan lintasan produksi. Hal ini dapat dilakukan dengan metode line balancing yaitu metode penugasan sejumlah pekerjaan yang saling berkaitan dalam satu lintasan produksi sehingga setiap stasiun kerja memiliki waktu yang tidak melebihi waktu siklus dari stasiun kerja tersebut. Metode line balancing yang digunakan adalah metode heuristik yang terdiri dari: metode bobot posisi (Ranked Positional Weight), metode pembebanan berurut (Large Candidate Rule), dan metode pendekatan wilayah (Region Approach). Dari ketiga metode Heuristik yang digunakan sebagai solusi penyeimbangan lintasan, terjadi perbaikan performansi dengan nilai yang sama pada lintasan produksi. Nilai efisiensi lintasan (line efficiency) meningkat menjadi 94,07 % dari 62,71 % pada kondisi awal. Nilai keseimbangan waktu senggang (balance delay) turun menjadi 5,92 % dari 37,28 % pada kondisi awal. Waktu menganggur (idle time) turun menjadi 12,39 menit dari 116,87 menit pada kondisi awal. Nilai smoothness index juga turun menjadi 7,44 dari 64,67 pada kondisi awal. PT XYZ is one of the company which refers to furniture industries sector. The problem which faced by this company is unbalance of the production line which is caused by the unequal of work responsibility distribution in each work station. This problem caused the performance of line balance doesn’t work properly. To solve this problem we need to do the line balancing of production line. It can be done by line balancing methode that assigns a number of work which is related in one production line until each work station has efficient time which is not more than the cycle time of the work station. Line balancing methode that used is heuristic methode which is devided into ranked positional weight methode, large candidate rule methode, and region approach methode. From those three heuristic methode that used as solution of line balancing, there was improvement happenned with the same value in doors of production line. Line efficiency increased into 94,07% from 62,71% at the beginning condition. Balance delay increased into 5,92% from 37,28% at the beginning condition. The idle time descreased into 12,39 minutes from 116,87 minutes at the beginning condition. The smoothness index descreased into 7,44 from 64,67 at the beginning condition.
