Neue Entwicklungen

In modernen Produktionen ist Lean Manufacturing einer der wichtigsten Treiber für Produktivitätssteigerungen. Durch neue Entwicklungen im Bereich Industrie 4.0 können Impulse im Lean Manufacturing gegeben werden. An der OTH Regensburg wird getestet, wie kostengünstige Kamerasysteme helfen können, Verschwendungen sichtbar zu machen und zu minimieren. Es zeigt sich, dass auch mit geringen Investitionskosten neue Potentiale zur Verschwendungsreduktion aufgedeckt werden können.   In modern production lean manufacturing is one of the most effective drivers for productivity. Due to new developments in the Industrie 4.0-campaign new impulses can be given into lean manufacturing. Experiments at OTH Regensburg indicate that a low-cost camera system can help to make waste visible and minimize it. This shows that with low invest costs, new potentials for waste reduction can be revealed.

The paper deals with the issue of increasing production processes efficiency, stabilization and also increasing the labor productivity through the implementation of lean manufacturing principles. Waste reduction and increase in the efficiency of manufacturing processes is a long-term, systematic matter, which requires the utilization of appropriate methods and methodologies. Therefore, this papers points out the growing importance of utilizing certain methods and principles which lead to the reduction of inefficient costs. The Value Stream Mapping (VSM) method, which can quickly point out existing reserves and provides an effective platform for the evaluation of lean manufacturing and Overall Equipment Efficiency (OEE) method, which evaluates the effectiveness of used manufacturing equipment are, both analyzed in detail.

A Company

The case of Marks & Spencer illustrates how a company has used a sustainability scorecard that awards provisional, bronze, silver, and gold ratings to participating suppliers to promote its sustainability programme. The scores are based on environment, human resources and ethical trade, and lean manufacturing. Suppliers undertake self-assessments of the scorecard at least once a year, which are subject to audit and assurance. The programme has delivered substantial savings through waste reduction and environmental efficiency amounting to over £600 million since 2007.

Purpose Non-value adding activities or wastes in the lean term have been the major challenge of the construction industry. Numerous studies have been conducted to investigate how such wastes can be reduced so as to improve the performance of the construction industry. However, the aspect of bricks production process (BPP) has not been extensively covered. Therefore, the purpose of this paper is to investigate the application of lean manufacturing concepts in BPP with a view to identifying the various wastes in the practice, the causes of these wastes and how such wastes can be reduced. Design/methodology/approach Mixed methods research design was adopted by the researchers where literature review was first conducted to establish the fundamental theories and practice standards of lean manufacturing process. Thereafter, a phenomenological study was carried out in a Shelter Clay and Brick Factory located in Minna, Niger State, Nigeria. The data obtained in the phenomenological study were analyzed through content analysis. These data served as the basis for the validation survey that subsequently followed the phenomenological study. Findings The findings in the study show that poor or inadequate supervision is the main factor responsible for wastes such as excessive drying of bricks, overheating of bricks and re-glazing of bricks in Nigerian BPP. Research limitations/implications The study focused on the various wastes in Nigerian BPP. It also focused on the various lean tools/techniques that can be adopted to reduce the wastes. Aspects such as the percentage of the wastes and their cost implication on the factory were not covered during the study and could be further investigated by prospective researchers. Practical implications The study provides knowledge on how lean thinking can be adopted to reduce wastes in BPP. Such knowledge may be beneficial to the present and prospective bricks producers. This implies that the proposed framework in the study allows producers of bricks to identify gaps in their implementation efforts, focus attention on areas that may require improvements, and access the benefits of lean approach in their factory products. The proposed framework may also be beneficial to the academics. Originality/value This paper first gain originality in the study context to propose for a lean framework that can be adopted to reduce wastes in BPP. Furthermore, the paper has not been previously published and all the information obtained from other sources are duly referenced.

Companies implement lean manufacturing (LM) tools in their production processes to reduce waste; however, it is difficult to quantify the effect on benefits gained after their implementation. This article proposes a structural equations model (SEM) that relates three LM tools associated with quality as total quality management (TQM), waste, and right first time (RFT) as independent variables associated with commercial benefits gained as a dependent variable. Those four variables were related by six hypotheses that were validated with information from 169 responses to a survey applied to the Mexican maquiladora industry. Partial least squared was used to validate the hypotheses as direct effects. The sum of indirect and total effects was also estimated, and a sensitivity analysis was developed for relationships between variables. Findings indicate that TQM directly affects waste reduction, drives doing RFT, and directly and indirectly affects the commercial benefits gained.

To reduce that waste, lean manufacturing approach is required. industry was 12,05%. The recommendations for increase PCE are relayouting the plant and change the order schedulingof raw materials. These recommendations could increase PCE score  to 15,68 %.Keywords: Waste, value stream, “Mi Lethek”, lean manufacturing ABSTRAK Industri “Mi Lethek” merupakan industri yang menghasilkan produk berupa mi kering berbahan baku tepung tapioka. Pada proses pengolahan mi di industri “Mi Lethek”, terdapat berbagai pemborosan () yang dapat merugikan industri. Diantara pemborosan yang terjadi berupa persediaan bahan baku yang belum diperlukan dan transportasi berlebih. Untuk mereduksi pemborosan tersebut diperlukan suatu perbaikan pada   menggunakan pendekatan . Pendekatan aktivitas yang ada pada industri “Mi Lethek”. Aktivitas-aktivitas tersebut kemudian digolongkan menjadi dua jenis aktivitas, yaitu aktivitas yang memberikan nilai tambah dan aktivitas yang tidak memberikan nilai tambah. Waktu dari masing-masing aktivitas tersebut yang selanjutnya digunakan untuk menghitung nilai (PCE). nilai pada produk dibandingkan total waktu yang digunakan produk selama dalam proses. Berdasarkan penelitian yang telah dilakukan, didapatkan nilai PCE awal dari industri “Mi Lethek” sebesar 12,05 %Perbaikan yang dilakukan ialah dengan mengubah tata letak pabrik dan melakukan perbaikan penjadwalan pemesanan bahan baku.
