5G Patent Licensing in Industrial Internet of Things : An analysis of patent licensing design criteria for future licensing of 5G in the segment of Industrial Internet of Things
(2022) Harder, Leonard; Larsson, Henrik; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Petrusson, Ulf; Heiden, Bo
The global trend of Internet of Things is spreading into the industrial sector, driven of gains in efficiency and cost reduction. Wireless technologies lay the foundation of IoT and 5G has the possibility to enable new use-cases for the industry. An effective licensing solution is requested to help spread the adoption of the technology while also incentivizing further research and development in cellular technology. The aim of this thesis is to investigate and evaluate design criteria of such a solution. This is important as it is likely to increase adoption rate and lower transaction cost associated with acquiring technology licenses for 5G. This in turn also supports innovation. The study was conducted in two parts consisting of a literature review and a series of semi-structured interviews respectively. The interviewees represented telecom companies, IIoT OEMs, manufacturing companies, academia and licensing entities. The study also analyses the case of automotive IoT licensing of Avanci and analyses its transferability to the case of IIoT. The results collected were then triangulated and analyzed, and conclusions were drawn. The study concluded that 5G contributes a lot of value to IIoT, especially within low latency and high reliability applications. Furthermore, a patent pool is likely a suitable solution, primarily due to the market characteristics of IIoT. These characteristics include, but are not limited to, the numbers of both SEP holders and implementers, and their desire to have a transparent, predictable, and simple licensing arrangement.

A Comparative Life Cycle Assessment of Advanced Processes for the Removal of Pharmaceutical Residues in Wastewater A Detailed Analysis Based on a Pre-study by Gryaab at Rya Wastewater Treatment Plant
(2022) Andersson, Sara; Karlsson, Maria; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Peters, Gregory; Peters, Gregory
There are no requirements for wastewater treatment plants to treat pharmaceutical residues today. However, the Swedish Environmental Protection Agency has distributed grants to investigate solutions for improving the aquatic environment. Gryaab received grants in 2019 to examine processes for the removal of pharmaceutical residues. A pre-study including a multicriteria-analysis was conducted where three processes were investigated: ozonation, Pulverized Activated Carbon (PAC), and Granular Activated Carbon (GAC). The result showed the importance of further studies on the processes’ environmental impact, leading to this life cycle assessment (LCA) study. This LCA study analysed the processes from five midpoint impact categories: global warming potential, fossil depletion, energy use, eutrophication potential, and acidification potential. The aim was to provide Gryaab with useful data regarding which of the three processes is the environmentally preferable choice and regarding the major environmental impacts of each advanced process. Furthermore, several sensitivity analyses were made to depict what parts of the advanced processes are most crucial for the total environmental impact. This study included two functional units to enable comparisons with both the pre-study and with other LCA studies. They were: the treatment of Gryaab’s wastewater for the removal of pharmaceutical residues for one year; and the treatment of one m3 of wastewater to this end. The calculations in this LCA were made in the software GaBi 9.2.1 Education, where the three processes and the existing sludge treatment were modelled separately. All flows were added in GaBi per m3 of wastewater and then scaled up for the yearly functional unit. According to the results, ozonation with wind power and the GAC process with renewable GAC, wind power, the largest possible bed volumes, and a regeneration plant at Rya wastewater treatment plant were considered the two most preferable alternatives in terms of environmental impact. Ozonation contributed the most to the midpoint impact category energy use. The PAC process contributed the most to global warming and acidification, while global warming was most significant for the GAC process. The value of using renewable alternatives where it is possible was thus strengthened. However, the environmental benefit of advanced wastewater treatment in comparison to its environmental burden must be further analysed to conclude if an implementation is environmentally advantageous.
A Comparative Life Cycle Assessment of Nudie Jeans’ Repair and Reuse Concept
(2019) Saric, Mate; Nellström, Maja; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Janssen, Mathias; Brinkberg, Eliina; Andersson, Simon
As one of the largest and most polluting industries, the fashion industry plays a significant role regarding the ongoing degradation of the environment. Nudie Jeans is a Swedish denim company that has taken an active approach by contesting the current paradigm of producing fast fashion, which contributes to the throwaway society, which in turn contributes to polluting the environment. Instead, they focus on giving their jeans a narrative, where ageing and letting the jeans break in is encouraged by the means of their Repair and Reuse concept. This Master’s thesis has investigated to what extent this concept helps mitigate environmental impacts with respect to a studied pair of Nudie Jeans entire life cycle using the Life Cycle Assessment method with the help of the LCA software GaBi. A linear case, where the studied jeans were assumed to be discarded after their functional life time had expired, was compared to a circular case, which assumed an extension of the functional life time through repairing and reusing the jeans three times. These two cases where compared with regard to the environmental impact they cause per year that they are worn. According to the results, the environmental impact decrease by extending the life time of the jeans. Thus, for each added event of reuse, the environmental load associated with the life cycle of the studied pair of Nudie Jeans decrease. However, the decrease occurs at an increasingly lower rate late with increasing number of reuses. Active measures that can be taken in order to further reduce the Repair and Reuse system includes decreasing the environmental impact related to maintenance of the jeans and repairing the jeans. For example, decreasing the frequency of washing and tumble drying will decrease the environmental impact. Moreover, the paper bag that customers get when they repair their jeans at a Repair Shop, were identified to be a considerable source of environmental impact with regard to the Repair stage of the Repair and Reuse concept. Valuable insights were identified, which indicate that Nudie Jeans is contributing to mitigating environmental impact within the fashion industry by promoting their Reuse and Repair concept. The results of this study imply that considerable environmental impact could be mitigated if more actors in the fashion industry implement an approach similar to Nudie Jeans’ Repair and Reuse concept.

A Comparison of Different Frameworks for Product Environmental Performance A life-cycle-Based Environmental Assessment of HVO from Used Cooking Oil (UCO) based on EPD, PEF and REDII frameworks
(2021) Nojpanya, Pavinee; Jogner, Carolina; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Baumann, Henrikke; Rydberg, Tomas
In this project, Product Environmental Footprint (PEF), Environmental Product Declaration (EPD) and the recast of the Renewable Energy Directive (REDII) framework were assessed and compared through the application on the case study of Hydrotreated Vegetable Oil (HVO) from Used Cooking Oil (UCO). The case study is part of the Impacts on Fuels Producers and Customers of Conflicting Rules for LCA (ICON) project to gain a deeper understanding on the differences between different environmental frameworks. The assessment was done based on the life cycle of the UCO-based HVO. The applied functional unit was 1 MJ of the studied HVO used by a heavy-duty truck (Euro V). The UCO was assumed to be a mixture of palm oil and rapeseed oil. The impact category that was chosen to be assessed was climate change as it was the only impact category the three frameworks have in common. The results show that there are differences between the PEF, EPD and REDII frameworks, which led to different results. The highest impact (51.3 g CO2-eq) was obtained when the PEF framework was applied and the REDII frameworks gave the lowest impact (11.9 g CO2 -eq). The results in EPD and REDII shows 70% and 77% respectively lower impact compared to the PEF. The observed differences between the frameworks were the choice of allocation method when secondary material was used, allocation hierarchy for multifunctional processes, the assessed number of elementary flows and impact categories, the CFs, the accounting of biogenic CO2 and the downstream process. The upstream processes gave the highest contribution to the results in PEF, while for the EPD and REDII it was the hydrogen production. In addition, the UCO collected in Sweden was the most environmentally preferred alternative compared to UCO from China. However, the lack of a specific ruleset such as PEF Category Rules (PEFCR) and EPD’s Product Category Rule (PCR) for biofuels may affect the reliability of the results in this case study.
A comparison of manufacturing companies in Sweden and their use of parameters within material planning
(2023) Turesson, Felicia; Bergström, Ottilia; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Chalmers University of Technology / Department of Technology Management and Economics; Jonsson, Patrik; Jonsson, Patrik
To reach high performance in an effective and efficient way, material planning is an aspect to consider. Material planning has different effects depending on how it is applied within the company’s environment. Furthermore, managing parameters within material planning is one way to balance supply and demand in an organization. How manufacturing companies are working and using the parameters within material planning is an interesting theme that is relevant to investigate today and hence this theses project was requested. This master thesis project was a collaboration with the consultant company Meridion AB who is acting within the area of supply chain management. The focus of this thesis project was regarding the effects of parameters within material planning and how it can be used by companies in order to be more efficient and effective. This thesis project has been divided into two parts, where the first part was a comparative study of 10 manufacturing companies within different industries. The analysis has been done by quantitative analysis in the business intelligence tool Qlik for the comparative part of the study. Furthermore, a deeper investigation was performed, and a qualitative analysis was conducted at the case company KraftPowercon Sweden AB, this was considered as the second part of this thesis project. The findings showed that there is a high variation between the companies and the frequency of updating parameters and conducting changes in their planning data, hence there is potential for development. The items analyzed were purchased items that were considered as active for the companies. During the analysis, different factors were taken into consideration in order to find similarities and differences between the companies. These factors were the items’ lead time, material planning method and sourcing strategy. Regarding the second part of the study, where a deeper investigation was conducted at KraftPowercon, it was possible to understand underlying causes of the quantitative data and to understand the findings. This master thesis aimed to find relevant conclusions and recommendations in order for both customers and consultants to continue the work with parameters within material planning. However, the main conclusion is that there is a need to work more with parameters and to implement a structured way of working with it. Furthermore, due to the high amount of data, a business intelligence tool like Qlik could be used as a helping tool to manage the data.
A Conceptual Data Model for Sustainability Tools
(2023) Enciso Lopez, Laura Karina; Lopez, Socorro Rae; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Chalmers University of Technology / Department of Technology Management and Economics; Lundqvist, Mats; Mansoori, Yashar
In response to environmental degradation and social inequality, nations have expressed the need for a sustainable development trajectory, most notably through the creation of the Sustainable Development Goals. As the pressure to comply with sustainability commitments increases and governments gain greater insight into the environmental and social performance of different sectors, organizations will need to find new ways to meaningfully generate sustainable value. However, implementation remains difficult because sustainability is a complex issue that requires systems thinking, a macro-vision, and a multidisciplinary approach. Sustainability toolkits can help organizations overcome these challenges by providing them with a diverse array of frameworks and strategies to follow. If stakeholders choose the wrong tool or use tools incorrectly, however, they run the risk of losing valuable resources and contributing to greenwashing. Thus, there is a need to guide stakeholders in decision making around sustainability tools themselves. In an effort to contribute to the field of research supporting the sustainability transition, this study aims to develop a conceptual data model to organize a sustainability toolkit in a manner that supports practitioners in selecting tools and subsequently utilize this organizational structure to reveal insights about an existing sustainable entrepreneurship and innovation toolkit, known as the ENHANCE toolkit.

A cost comparison between an outsourced and in-house storage solution
(2017) Alickovic, Denis; Behrman, Jesper; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Chalmers University of Technology / Department of Technology Management and Economics
It has become a survival factor to have a constantly evolving business in order to handle today’s changing markets. The distributor role in the supply chain has evolved, leading to more pressure on cutting both costs and lead times. The usage of third party logistics providers has increased during the last decade. Companies outsource parts or entire activities to meet customer demands as well as to be able to focus on the company’s own core competence. Focus Nordic have an established partnership with a third party logistics provider that handles parts of the warehouse operations, in order to cope with current space issues at the central warehouse. Even though Focus Nordic outsource some of the storage to an external partner there are still other issues connected to the lack of space, for instance lack of picking locations, congestions, picking routes etc. Focus Nordic has considered the possibility of expanding the central warehouse to increase the capacity, thus enabling to store all goods at the central warehouse, excluding the external third party logistics provider from the structure. The purpose of this master thesis was to provide the company with a data foundation, comparing the current outsourced cost structure with a future in-house one. In addition to the cost comparison the study aims towards identifying areas of improvement within the current warehousing activities that could be further investigated during a potential expansion. To be able to investigate and reach the objectives of the study both quantitative and qualitative data have been gathered using a triangulation approach. This further means that multiple sources of information have been used in order to increase the reliability and validity of the study. The theoretical and empirical findings were combined in order to conduct the analysis and provide the company with answers to the main objectives. The results show that the total cost in a future structure would be decreased with an expansion of the required capacity of 600 m2. The main differences in the new structure is that all cost categories related to the partnership would be decreased or cease to exist, except for the storage rent that would increase. An in-house solution would also require some initial material investments during the first period for new pallet locations. The second part of the analysis showed that ergonomics, goods reception, storage assignments and picking routes were all identified as clear areas of improvements that could be combined with an expansion in order to develop the future structure. However, to successfully improve these areas more than 600 m2 would be needed, that would require further investments.

A Dive Into Manually Picked Seafood Distributing Warehouse Optimization An investigation of how to create more efficient manual picking processes in seafood distributing warehouses
(2023) Widlöf, Matilda; Oresten, Tryggve; Chalmers tekniska högskola / Institutionen för teknikens ekonomi och organisation; Chalmers University of Technology / Department of Technology Management and Economics; Lantz, Björn; Lantz, Björn
Seafood distributing warehouses struggle with low efficiency. It is an industry where historically low focus has been placed on developing the warehouses capabilities meaning that they have typically lagged behind other industries. There exists plentiful literature on the best practice of designing ware- houses but none which tries to adapt the best practice to the particular circumstances of the seafood distributing industry, a gap this study aims to bridge. Through an abductive case study focusing on theory elaboration the specific context was understood. Literature was used to find the best tools to use for the setting and in the case of storage assignment strategy simulations were utilized in order to evaluate the best technique. The results of this thesis indicate best ways of designing warehouses when it comes to their shape, layout, batching method, zoning methodology, choice of pallet racks and storage location assignment method for article placement. Of special interest is the best storage location assignment method found by the study which solely utilized frequency of demand for allocating storage spaces, though there exist methods this study did not attempt which might be superior. The study investigated cluster based models incorporating association into the model but these were shown to be subpar. Practical consequences of implementing the guidelines presented by this study include a more resource efficient manually picked seafood distributing warehouse with shorter lead times and more efficient storage.
