Value Stream

In today’s competitive market place, manufacturing companies must apply continuous process improvement in order to maintain a returning customer base. One way of achieving constant process improvement is through value stream mapping. Value stream mapping is used to visualize the current processes for easier understanding and problem identification. A well-defined problem statement will ensure a successful outcome of a project improvement process. This research provides a case study performed on a rope manufacturing process. A current state value stream map is created, and the possible improvements are suggested. The implemented results are shown in the form of future state map. The results show that, after waste elimination and structural revision, a manufacturing process becomes more efficient, enabling the customer to receive an order significantly faster.

Process Plan

Carbon intensity reduction and energy utilization enhancement in manufacturing industry are becoming a timely topic. In a manufacturing system, the process planning is the combination of all production factors which influences the entail carbon emissions during manufacturing. In order to meet the current low carbon manufacturing requirements, a carbon emission evaluation method for the manufacturing process planning is highly desirable to be developed. This work presents a method to evaluate the carbon emissions of a process plan by aggregating the unit process to form a combined model for evaluating carbon emissions. The evaluating results can be used to decrease the resource and energy consumption and pinpoint detailed breakdown of the influences between manufacturing process plan and carbon emissions. Finally, the carbon emission analysis method is applied to a process plan of an axis to examine its feasibility and validity.

Stream Model

Increasing concern over the resource consumption and utilisation alongside of any manufacturing process decides the sustainability of the product. Many contemporary organisations due to stringent government regulation and policies now focus on management of waste generated across their units. Value Stream Mapping (VSM) generally focuses on reducing task time and thereby reducing monetary over heads. From the environmental perspective, the type of waste produced is important because of the difference in level of toxicity and environmental impact. This work focuses on imbibing environmental waste into the lean method of value stream mapping. The proposed integrated model was implemented in a case organisation and environmental impact was computed. The developed model can be used by stake holders and represent environmental impact at individual process and product levels to align organisation practices with strategic objectives for waste reduction.

The purpose of this paper is to increase the productivity of a ceramic tile manufacturing process using lean manufacturing technique. The current system of the ceramic tile manufacturing process has been mapped using Value Stream Mapping (VSM) tool, which is a lean manufacturing tool and the wastages in the current system are identified. Afterwards, future state has been created by using VSM tool, which has enhanced process ration by decreasing maximum possible waste in the manufacturing process. The case study demonstrates how the VSM tool has been used to identify and reduce waste in the manufacturing process by 26%, unnecessary inventory by 8.33% and working time of the color-mixing department by 21.57%. This flexibility enhancement causes 2.67% shorter lead time, 2.70% higher value-added ratio and frequent product delivery leading to more profits.

PT. WIKONI adalah perusahaan fabrikasi baja yang memproduksi pipa dengan salah satu produknya adalah pipe intake. Dari hasil pengamatan ditemukan bahwa di lantai produksi PT. WIKONI terdapat pemborosan yang tidak memberi nilai tambah didalam memproduksi produk pipe intake, hal ini menyebabkan perusahaan sulit untuk memenuhi target permintaan konsumen dengan rata-rata 11 unit/hari. Penggambaran sistem produksi saat ini dilakukan dengan menggunakan Current State Value Stream Mapping. Hasil perhitungan didapat Process Cycle Efficiency (PCE) kondisi saat ini sebesar 84,46% dan hasil identifikasi pemborosan dengan menggunakan Process Activity Mapping (PAM), didapat bahwa pemborosan dominan yang terjadi pada proses produksi pipe intake adalah pemborosan delay sebesar 57600 detik. Dari analisis penyebab terjadi pemborosan terlihat bahwa akar permasalahan dari pemborosan tersebut adalah terlalu besar waktu untuk penyimpanan dan kurangnya manpower pada stasiun kerja machining. Berdasarkan akar permasalahan tersebut, diajukan beberapa usulan yaitu dengan menghilangkan waktu penyimpanan pada stasiun kerja sand blowing, machining, dan finished goods dan menambah manpower pada stasiun kerja machining. Hasil dari usulan ini kemudian digambarkan dengan Future State Value Stream Mapping dan mampu meningkatkan PCE menjadi 91,22%.   Kata kunci: Value Stream Mapping, Lean Manufacturing, Process Cycle Efficiency, Process Activity Mapping
