Value Stream Mapping and Earned Value Analysis: A Case Study in the Paper Packaging Industry in Brazil

Abstract

The study approached the application of the Value Stream Mapping and Earned Value analysis methods in a Pinch Bottom with Simple Fold (PBSF) paper bag production line in an industrial packaging enterprise of multiwall paper bags located in Brazil. From the joint application of the mentioned methods, a better diagnosis of the situation was obtained, and the opportunities of eliminating wastes, of operation enhancement, and of a better monitoring of the involved costs appeared, bringing potential production gains and quality to the enterprise. As a contribution of this work, it can be highlighted the presentation and discussion about the complementarity of a Lean Manufacturing tool with a Project Management Methodology.

Value stream analysis of a waste picker cooperative

“…Among the plethora of tools that Lean incorporates, VSM is considered one of the most essential (Garza-Reyes et al, 2018). In this way, VSM is the main mapping tool pointed out by the literature to identify waste (Andreadis et al, 2017;Pereira et al, 2017), facilitating the systematic identification of waste and supporting decision-making to prioritize and coordinate continuous improvement initiatives, providing a holistic view of the value streams executed to deliver a product or service to customers (Martins and Cleto, 2016;Shou et al, 2017). In addition, this tool can suggest improvements to the worker's routine, such as improving ergonomic matters and acting on their health and safety (Cherrafi et al, 2016).…”

Value-Stream Mapping as a Tool to Improve Production and Energy Consumption: A Case Study of a Manufacturer of Industrial Hand Tools

“…Value-stream mapping (VSM) has its roots in the Japanese company Toyota and is an integral part of the lean manufacturing philosophy [1,2]. The idea for this tool was born in the 1950s, when Toyota, trying to improve its production processes, began to focus on eliminating all forms of waste in production [3,4].…”

“…Nowadays, the clients require the cheapest products simultaneously with high quality, which is difficult for producers to achieve [1,[12][13][14][15][16]. It is due to the fact that recently most of the raw materials' prices have increased during the pandemic and economic crisis [17][18][19].…”

Using Value Stream Mapping to Eliminate Waste: A Case Study of a Steel Pipe Manufacturer

“…After that, Taiichi Ohno and Shigeo Shingo developed a waste visualization tool called Material and information flow mapping. In 1978, for the first time, Taiichi Ohno presented the classification of muda, i.e., wastes occurring in an enterprise [1][2][3][4]. VSM was created as a solution to indicate the areas of waste present in the company and help in the development of possible improvements in order to reduce and eliminate mud [5][6][7][8].…”
