- Two change management strategies: a minimum change, exploitation strategy (kaizen) and a maximum output, exploration strategy (kaikaku) have been applied in a manufacturing case study. Value stream mapping and discrete event simulation were used to analyse the production system changes, with regards to robustness and total lead-time, to increase knowledge of how to choose change management strategy. The results point out that available time is crucial. It is important to consider not only product specification and return of investment, but also the change and risk management. Future research should develop engineering change management further.

- Improved material efficiency is a key to improve the circular economy and capturing value in industry. Material efficiency reduces the generation of industrial waste, the extraction and consumption of resources, and energy demands and carbon emissions. However, material efficiency in the manufacturing sector, as a means of improving the recyclability, reusability, reduction and prevention of industrial waste, is little understood. This study aims to investigate, on a micro-level, further material efficiency improvement opportunities, barriers and strategies in selected manufacturing companies in Sweden, focusing on increasing waste segregation into high quality circulated raw material. Improvement opportunities at large global manufacturing companies are investigated; barriers hindering material efficiency improvement are identified and categorized at two levels; and strategies that have been deployed at manufacturing companies are reviewed. Empirical findings reveal (1) further potential for improving material efficiency through higher segregation of residual material from mixed and low quality fractions (on average, 26% of the content of combustible waste, in weight, was plastics; 8% and 6% were paper and cardboard, respectively); (2) the most influential barriers are within budgetary, information, management, employee, engineering, and communication clusters; (3) a lack of actual material efficiency strategy implementation in the manufacturing companies. According to our analysis, the majority of barriers are internal and originate within the manufacturing companies, therefore they can be managed (and eradicated if possible) with sufficient resources in terms of man hours, education and investment, better operational and environmental (waste) management, better internal communication and information sharing, and deployment of material efficiency strategies.

Material efficiency measurement : Swedish case studies
- 2018

- A major factor in the continued deterioration of the global environment is unsustainable management of resources that includes the type and quantity of resources consumed and manufactured as well as the subsequent generation and treatment of wasted materials. Improved material efficiency (ME) in manufacturing is key to reducing resource consumption levels and improving waste management initiatives. However, ME must be measured, and related goals must be broken down into performance indicators for manufacturing companies. This paper aims to improve ME in manufacturing using a structured model for ME performance measurements. We present a set of ME key performance indicators (ME-KPIs) at the individual company and lower operational levels based on empirical studies and a structured literature review. Our empirical findings are based on data collected on the performance indicators and material and waste flows of nine manufacturing companies located in Sweden. The proposed model categorizes ME-KPIs into the following categories: productive input materials, auxiliary input materials, output products, and residual output materials. These categories must be measured equally to facilitate the measurement, assessment, improvement and reporting of material consumption and waste generation in a manufacturing context. Required qualities for ME-KPI suggested in literature are also discussed, and missing indicators are identified. Most of the identified ME-KPIs measure quality- and cost-related factors, while end-of-life scenarios, waste segregation and the environmental effects of waste generation and material consumption are not equally measured. Additionally, ME-KPIs must also be connected to pre-determined goals and that defining or revising ME-KPIs requires communication with various external and internal actors to increase employees’ awareness and engagement.

Material Efficiency Measurement: Empirical Investigation of Manufacturing Industry

- Improving material efficiency contributes to reduce the volume of industrial waste as well as resource consumption. However, less has been published addressing on what to measure for material efficiency in a manufacturing company. This paper presents the current practice of material efficiency performance indicators in a manufacturing context through a bottom-up approach. In addition to literature review, the empirical data was collected via a multiple case study at seven global manufacturing companies located in Sweden. The results show that existing material efficiency indicators are limited and are mainly measured as a cost or quality parameter rather than environment. The limited number of measurements relates to the fact that material efficiency is not considered as a central business in manufacturing companies and is managed by environmental department with limited correlation to operation. Additionally, these measurements do not aim to reduce waste volume or improve homogeneity of generated waste.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Previous environmental studies indicate several barriers to circular economy and material efficiency including a lack of detailed methodologies for manufacturing improvement in terms of environmental and operational performances to measure, monitor and evaluate material consumption and waste generation. A lean and green tool, the green performance map (GPM), is an appropriate tool for different environmental initiatives including training, improvement, reporting and development. Through literature review and multiple case study methodology, this chapter presents the current application of GPM in industry and its usage to regularly measure and monitor material efficiency measurements on different levels and to remove barriers to improved material efficiency.

Konferensbidrag (refereegranskat)abstract
- What constitutes a Smart Factory, and how can a company’s capabilities to develop their smart factory be improved? South Korean and Swedish manufacturing perspectives are here illustrated by company examples of smart factory solutions and related strategic aspects of their digitalization process. It is concluded that the “smart-factory-capability” of a manufacturing company is integrated with its corporate production systems and includes perspectives on application areas, value adding processes as well as enabling technologies. It is furthermore challenged by the transformational inabilities of its legacy systems. The paper contributes to the definition of the smart factory and its corresponding development scheme.

- Companies are challenged to achieve maximised benefits in time, money and novelty when introducing new products or technologies into their existing manufacturing systems. This paper set the focus on the introduction of new materials into existing products and if the adverse effects on manufacturing will outweigh the benefits. An automotive case was studied where discrete event simulation was used as tool to evaluate process consequences when introducing new material and process technologies into the production system. The question concerned if discrete event simulation can verify production system capabilities even in early conceptual design stages. The case analysis is concluded by three challenge areas concerning early stages of production system design. The difficulties of evaluating operational key performance indicators early in design processes become evident and needed future research efforts within the area are pointed out.

Tidskriftsartikel (refereegranskat)abstract
- This study analyzes the challenges of applying discrete event simulation in the early stages of production system design. Highlighting the implications of new production processes and technologies leading to improved competitiveness, this study provides novel contributions to the understanding of discrete event simulation based on three case studies of the transformation of legacy production systems in the heavy vehicle industry. The findings of this study show that equivocal or ambiguous understanding about new production processes or technologies, and uncertainty about necessary data input and the interrelation of subsystems in production, are critical in addressing discrete event simulation-related challenges. These findings highlight the need for an established process to manage assumptions and simplifications during the design, development, and deployment of discrete event simulation models as a countermeasure against uncertainties, improving manufacturing system design and practice.
