The Impact

Currently, the topic of introducing lean production is becoming more and more relevant, which is confirmed by the number of enterprises involved in this process, as well as widespread coverage in the media and popular science publications. The economic component of these projects plays a special role in the implementation of lean production, since with the correct calculation of the economy at the start, the rate of implementation is much higher, and the percentage of adoption of the implemented tools is higher. Today there are many ways to calculate the economic effect, but most of them are general in nature and do not fully demonstrate the specific results of changing processes. In addition, natural rather than financial indicators are often used, which complicates the overall assessment of the efficiency of the applied solutions. The purpose of this article is to assess the impact of value stream mapping, as a key tool of lean production, on eliminating losses and improving the productivity of the enterprise as a whole. The practical basis of the research was the experience of implementing lean manufacturing in more than 2 thousand commercial enterprises of various industries, with revenue from 100 million to 25 billion and an average number of 10 to 10 000 people.

Lately, value stream mapping (VSM) is integrated with tools and techniques that belong to other areas of knowledge such as risk management (RM). It is well known tool in showing the value, value stream and the flow which represents three of lean manufacturing (LM) principles. This integration, gives more benefit in covering two of VSM issues such as considering the variability and uncertainty of production processes. In this paper, a model named variable value stream mapping (V-VSM) that integrates the two was showed, explained and tested. The model helps to generate the VSM in a dynamic way with the identification of current and potential risks. These risks might happen in the future bringing a strong impact on not reaching the main objectives in the defined time and cost. The model has been tested by conducting a case study in food sector. A current state map was built using both models, traditional VSM and VVSM. The results showed the effect of variability and uncertainty on the total cycle time (CT) and lead time (LT) values, where the traditional VSM failed to show it by being a static tool. Comparing the results of both models show the differences in presenting the real state of manufacturing environment..

The importance of lean manufacturing concepts has been discussed many times over the few decades. The most important elements in lean manufacturing practices are value stream mapping (VSM), Kaizen events, load leveling (heijunka), etc. In this case study, a real-world clock assembly simulation has been used to study the performance improvement in terms of production flow and lead time after introducing lean concepts. In each round of simulation, the lean concepts have been introduced one by one and performance metrics were recorded. After implementing the concepts, the productivity was improved enormously. So, this simulation study emphasizes the importance of continuous improvement of production flow through lean concepts in a real production setting.

  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.
