Roller hemming is usually applied for hang-on-parts such as hoods, doors or trunk-lids which all have complex non-linear geometries. The flange is often hemmed along both surfaces and edges which have 3D curvilinear shapes. Minimization of hemming defects and the requirement to improve cycle time of the roller hemming process are essential for roller hemmed hang-on-parts in the automotive industry. Different systems such as the driven roller hemming provide the possibility to increase the strain rate without loosing surface quality and dimensional stability. Investigating the influence of friction during roller hemming, results will give an understanding of the advantage for mentioned roller hemming systems.

The Impact

Time study is the process of observation which concerned with the determination of the amount of time required to perform a unit of work involves of internal, external and machine time elements. Originally, time study was first starting to be used in Europe since 1760s in manufacturing fields. It is the flexible technique in lean manufacturing and suitable for a wide range of situations. Time study approach that enable of reducing or minimizing ‘non-value added activities’ in the process cycle time which contribute to bottleneck time. The impact on improving process cycle time for organization that it was increasing the productivity and reduce cost. This project paper focusing on time study at selected processes with bottleneck time and identify the possible root cause which was contribute to high time required to perform a unit of work.

Balancing Efficiency

Balancing assembly line in a mass production system plays a vital role to improve the productivity of a manufacturing system. In this paper, a single model assembly line balancing problem (SMALBP) is considered. The objective of this problem is to group the tasks in the assembly network into a minimum number of workstations for a given cycle time such that the balancing efficiency is maximized. This problem comes under combinatorial category. So, it is essential to develop efficient heuristic to find the near optimal solution of the problem in less time. In this paper, an attempt has been made to design four different genetic algorithm (GA)-based heuristics, and analyze them to select the best amongst them. The analysis has been carried out using a complete factorial experiment with three factors, viz. problem size, cycle time, and algorithm, and the results are reported.

  Penelitian ini ditujukan untuk menganalisis pemborosan produksi produk Jala Ikan KKP menggunakan lean manufacturing di PT. Indoneptune Net Manufacturing dengan memetakan aliran produksi dan menganalisisnya menggunakan value stream mapping (VSM). Analisis terhadap pemborosan dengan metode VSM dilakukan karena VSM dapat memetakan aliran informasi dan material dari awal sampai akhir dari value stream pembuatan suatu produk. Sehingga dapat dilihat proses mana saja yang merupakan pemborosan. Adapun VSM yang dibuat adalah current-state VSM karena dapat merepresentasikan kondisi saat ini dari aliran produksi yang ada. Hasil yang didapatkan setelah dibuat current-state VSM adalah aliran produksi produk jala Ikan KKP melewati proses spinning, ring roupe, netting dan finishing yang memiliki sub-sub proses yang berbeda. Dari setiap sub-proses tersebut dipetakan nama proses, jumlah waktu cycle time dan changeover time, level inventory, waktu kerja tersedia dan jumlah operator. Penganalisisan pemborosan dilakukan pada setiap sub-proses untuk dapat mengetahui nilai tambah proses tersebut terhadap produk utama yang sedang dikerjakan pada setiap tahapan proses yang berlangsung. Kesimpulan yang didapat yaitu pemborosan yang terjadi di departemen spinning salah satunya adalah delay time karena persiapan sebelum proses peleburan, waktu tunggu karena persiapan proses twist di departemen ring roupe, transportasi berlebih sebelum proses tatekan dan pengerjaan ulang di hoshu 2 di departemen finishing.

Lean Methods

Lean manufacturing first emerged in the automotive industry. However, low productivity and low efficiency in production are major problems for the majority of industries relying on a heavy workforce. Being one of these, the construction industry suffers from low productivity rates along with inefficient work practices. To prevent those, the industry has shifted its focus from the traditional approach to a more innovative one, which is called Lean construction. Lean construction aims to maximize value while minimizing waste. Therefore, it intends to create safer, smoother, and more efficient processes to eliminate waste. This chapter focuses on Lean construction and highlights the generic Lean tools and techniques practiced in the construction industry indicating its historical journey from Lean manufacturing. The chapter aims to raise awareness towards the efficiency of Lean methods in the construction industry with respect to practices observed in manufacturing.
