Starting Point

Over the past few decades, Lean Manufacturing (LM) has been the pinnacle of strategies applied for cost and waste reduction. However as the search for competitive advantage and production growth continues, there is a growing consciousness towards environmental preservation. With this consideration in mind this research investigates and applies Value Stream Mapping (VSM) techniques to aid in reducing environmental impacts of manufacturing companies. The research is based on empirical observation within the Chassis weld plant of Company X. The observation focuses on the weld operations and utilizes the cross member line of Auxiliary Cross as a point of study. Using various measuring instruments to capture the emissions emitted by the weld and service equipment, data is collected. The data is thereafter visualised via an Environmental Value Stream Map (EVSM) using a 7-step method. It was found that the total lead-time to build an Auxiliary Cross equates to 16.70 minutes and during this process is emitted. It was additionally found that the UPR x LWR stage of the process indicated both the highest cycle time and carbon emissions emitted and provides a starting point for investigation on emission reduction activity. The EVSM aids in the development of a method that allows quick and comprehensive analysis of energy and material flows. The results of this research are important to practitioners and academics as it provides an extension and further capability of Lean Manufacturing tools. Additionally, the EVSM provides a gateway into realising environmental benefits and sustainable manufacturing through Lean Manufacturing.

Ecological Performance

This chapter discusses the concept of ecological performance. Sustainable development has become a focus of governments, companies, communities, and even individuals. Manufacturing companies need a performance measurement that can balance between profit and environment. The concept of reduction of resource use and waste generation is not limited to the manufacturing processes of a focal company, but it can be embraced into product design that benefits the end users as well as stakeholders. Companies can build competitive advantages by integrating ecological performance into business value stream mapping. Reduction of resources and energy use can help companies to be cost effective and thus able to survive a market price war. Companies can enhance product quality through eco-design and sustainable manufacturing to preempt competitors. Companies can build green images to gain customer loyalty. Waste reduction can help companies to save capacity and be more flexible in shipment delivery and support customer dynamic needs.

Starting Point

Value Stream Mapping (VSM) is the one of the techniques used in lean manufacturing; it is a method of visually mapping a product’s production path (including materials and information) from door-to-door. Value Stream Mapping can serve as a starting point to help managers, engineers, suppliers and customers recognize waste and identify its causes. Traditionally VSM tool is used in manufacturing environment. In this study it has been applied for the distribution system. This study is conducted on a distribution company delivering automotive parts to the customers in and around Las Vegas. The primary objective of this system engineering approach is to create the present and future state Value Stream Mapping for a small sampling of three different categories of parts based on average monthly usage from the time they arrive on the receiving dock to the time they are placed into the delivery vehicle. In this work the value added and non-value added activities in the distribution process are identified. The future state map has been suggested with a set of short-term and long-term recommendations.

Manufacturing Productivity

Nowadays, manufacturing companies are involved in a big competition, each of them looking to increase productivity and profit by implementing best practices within the company. The present paper presents an analysis of best practices of manufacturing companies which contributes to increasing and improving the productivity, and also have been identified new trends regarding best practices implemented in manufacturing companies. In order to accomplish this research, has been analyzed a successful manufacturing company in the field of manufacturing and automation from Romania. To collect data for this study there were accessed two databases, different specialized websites in the field, but the most important source of information was obtained from the analyzed company. One of the best practices identified in this study was to improve the productivity through re-engineering, practice that the company studied has implemented. In order to highlight this good practice, namely reengineering, were analyzed in parallel both of existing manufacturing types from the analyzed company, respectively production on CNC processing centers and classical production. The exemplification of both types of productions was done by using a Lean Manufacturing method, namely Value Stream Mapping, identifying the operational flow of both types of production.

As a result of the recession in Saudi Arabia, the manufacturing companies start thinking to reduce the operational cost and increasing the productivity through lean manufacturing principles. This paper is focused on increasing the productivity of a paint manufacturing company through implementing some of the lean manufacturing techniques. First, Value stream mapping analysis carried on throughout the manufacturing process and the areas of improvements in the company has been identified using fishbone diagram. Second, Work Place Organization (5S), Single Minute Exchange of Dies (SMED), Work Standardization and Kanban are the lean manufacturing techniques selected to solve different problems facing the company in these areas of improvements. A systematic approach of each technique implemented to measure its effect on the company productivity. It is observed that, applying (5S) and (SMED) techniques in the filling process decreased the changeover time by 59% and increased the daily productivity. Pareto chart recommended using work standardization in the charging process led to reduce the defects batches by 57%. Kanban system eliminated the shortages of semi-finish product and increased the output of the pre-weighing batches by 57%. In addition, overtime hours reduced by 77% and waste handling reduced by 85% and 53% for the non-hazardous and hazardous waste respectively

Starting Point

A wide-spread approach to foster production and logistics related improvements on a system level is value stream mapping (VSM). It is often used as a starting point for implementing lean manufacturing in producing companies. VSM as a modeling approach contains two major phases – one is the analysis, another one the design phase. During these there is always the question of getting accurate information out of the production system to enable a constructive improvement. It can be distinguished between direct data acquisitions (observation, questioning, interviews) and indirect data acquisition (using IT systems) where both quantitative and qualitative data arises. Standard value stream design (VSD) offers no option to combine these data types, instead mostly deterministic values are used for assessing future states; this can lead to an illusion of accuracy. Thus in this paper it is shown how to combine different data types with an appropriate modeling using fuzzy variables in the course of VSD. The whole procedure is applied during a laboratory study to provide internal validity.

Starting Point

Lean healthcare aims to manage and improve the processes in the healthcare sector by eliminating everything that adds no value by improving quality of services, ensuring patient safety and facilitating health professionals’ work to achieve a flexible and reliable organization. Value Stream Mapping (VSM) is considered the starting point of any lean implementation. Some papers report applications of VSM in healthcare services, but there has been less attention paid to their contribution on sustainability indicators. The purpose of this work is to analyze the role of VSM in this context. To do so, a scoping review of works from recent years (2015 to 2019) was done. The results show that most applications of VSM reported are in the tertiary level of care, and the United States of America (USA) is the country which leads most of the applications published. In relation with the development of VSM, a heterogeneity in the maps and the sustainability indicators is remarkable. Moreover, only operational and social sustainability indicators are commonly included. We can conclude that more standardization is required in the development of the VSM in the healthcare sector, also including the environmental indicators.
