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..

  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.

PT. IE is engaged in the business of making Lighting and Lampposts. Based on observations and interviews, there are still some wastes that arise in the flow of the production process, among which there are still many wastes of waiting time, transportation, movement and inventory. These wastes cause the product completion time to be longer and the resulting quality decreases. To eliminate or reduce waste, it is necessary to apply Lean Manufacturing. Lean Manufacturing is a systematic approach to eliminating waste and changing processes by identifying and reducing waste with continuous improvement and striving to create a production flow along the value stream by eliminating all forms of waste and increasing the added value of products to customers. From the Pareto diagram, it is found that transportation waste has the highest percentage of 26.21%, waiting time is 21.38%, motion waste is 19.31% and waste inventories are 15.17%. while the results of the Value Stream Mapping Current State Map mapping obtained a production lead time of 7,680 seconds and a total cycle time of 6,660 seconds and a PCE Current State Map value of 53.09%. Identify the root causes of waste using Fishbone diagrams, 5 Why Analysis, 5W+1H, Fault Tree Analysis and FMEA. After corrective actions have been taken, based on the Value Stream Mapping Future mapping there is a decrease in production lead time to 5,220 seconds and a decrease in total cycle time to 4,860 seconds and an increase in PCE Future State Map to 68.10% so that there is an increase of 15.01% which shows The company's production process has become more Lean.PT.

The energy sector is perceived as one of the most exposed sectors to the consequences of weather risk both directly (damages of its infrastructure) and indirectly (frictions to the energy supply–demand balance). The main aim of this paper is to provide an insight into the impact of weather risk on economic activity of companies operating in the energy sector in Poland. The empirical objective is to examine whether energy companies: (i) identify their relevant weather risk exposures; (ii) evaluate the impact of weather risk in the cost-revenues dimension; and (iii) implement weather risk management tools, in this case—weather derivatives. In a methodical context, this study relies on a unique research approach and derives from works that examine companies’ risk disclosures in annual reports, by applying textual content analysis. The results indicate that Polish energy companies recognize the impact of weather risk on their performance, also in the cost-revenues dimension. However, although the reported weather risk management methods were diversified, the examined companies did not use weather derivatives to hedge their weather risk exposures. In the overall dimension, the companies leading with the perception and management of weather risk were diversified regarding performance and market size.

Spatial planning is managing the environmental, social and economic dimensions of development. Today the built environment suffers from a lot of natural hazards, resulted due to poor concentration over the environmental, social and economic aspects. Magnitudes and frequencies of these natural hazards has shifted from bad to worst in the recent past. Therefore, economic cost of these hazards has increased, and governments has been compelled to spend large amounts of public money to overcome these impacts on the built environment. Thus, in Sri Lankan context, these circumstances warrant the need to have a sustainable and realistic approach for the spatial planning in the built environment. Hence, the aim of this research was to enhance the cost and value efficiency in built environment against natural hazards through proper spatial planning in Sri Lankan context. Research was conducted mainly based on a questionnaire survey following the mixed research approach. Study identified the impact of poor spatial planning in the built environment in Sri Lankan context and study imparted set of guidelines to ensure effective spatial planning in the built environment in order to minimize the impact of adverse natural hazards. Finally, study concluded that, in order to establish a paradigm shift emphasizing the importance of effective spatial planning in the built environment, it is essential to have a clear understanding on natural process and other socio-economic concerns of the country.
