Abstract [en]

Accelerating technological developments and increasing competition make it important to secure the development of production solutions that allows for resource efficient layouts and continuous improvements. When developing production solutions, the usage of digital tools is an important asset that supports production preparation engineers in their work. However, the emerging possibilities to design production layouts where the operator and a robot collaboratively share a task, add more challenges for production preparation engineers. The production layout become more complex, with more parameters to analyze for a safe and secure working environment, supporting a safe interaction between technologies and operators. The design of human-robot-collaborative (HRC) layouts, with ever shorter product life cycles, could benefit from an increased use of digital tools, as ever more powerful simulation and design tools are available on the market. This paper will explore digital tools (such as simulation, emulation, visualization) and their potential contribution for different HRC layout designing steps. Based on this, the needs to be reflected in a guideline for a digitalized production preparation process will be explored from the perspective of developing a human-robot collaborative layout.. © 2022 The authors

Abstract [en]

If digitalization projects aim to effectively create value for a company, one precondition is having a shared view among company staff and project members of what the "desirable" value is. However, it has been shown that few companies fully understand the value that digitalization projects can create for them, while many companies still launch digitalization projects without this understanding. This contributes to the current "alarmingly" low success rate for digitalization projects. Development of effective methods to specify the desired values of digitalization projects is thus important. One step in developing improved specification methods is to ask what the possible barriers are to improving current value specification practices. The purpose of the current study is to address this. We analyzed several digitalization projects regarding how specifications of desired project value were carried out, finding that very limited resources are spent on specifying desired values in digitalization projects, and that this limits project success. Likewise, there are several barriers to increasing resources for specifying desired values. Our findings contribute to understanding the development of value specification methods that aim to overcome these barriers and thus could help improve the success rate of digitalization projects.

Abstract [en]

Having project goals that are shared among project members are preconditions for resource efficient as well effective projects and operations. However, specifying and communicating project goals require an ability to identify goals that are indeed commonly shared. Rapid technological developments may require digitalization projects that lead to large portions of existing company staff being redundant, making it possible to assume that the quest of finding a commonly shared view of what is resource-efficient' will be increasingly challenging. Development of methods to specify project goals that are incentivizing for all project members and staff can hence be assumed to be important. One step in developing improved specification methods is to ask how the process to specify desired value from digitalization projects handles possible disagreements of what is desired value'. The purpose of this study was to answer this question. We analyzed several digitalization projects, and how specifications of desired project results impacted project outcomes. We found that potential disagreements regarding desirable project outcomes generally are avoided by avoiding specification of what a desirable resource efficiency outcome is, and how actual project outcomes should be measured. However, we also found that this practice also led to unsatisfying project outcomes regarding resource-efficiency improvements, and that improved methods to specify desired value from digitalization projects should be developed. Our findings support earlier findings that the general failure rate of digitalization projects is high, often due to insufficient specification of desired projects outcomes before the projects are initiated. Our findings contribute to the understanding that despite this, there are also perceived benefits of spending limited resources on specification of desired outcomes. If attempts to improve the success rate of digitalization projects by improving specifications of desired project outcomes is to succeed, these perceived benefits must be considered. © 2020 The authors

Abstract [en]

Smart connected industrial products and the Internet of Things (IoT) are transforming the industrial business landscape in a radical way. To reach the full potential of IoT-Technologies manufacturing firms are forced to rethink almost every aspect of their value creation process. To utilize this promising digital technology and to cope with the new market conditions of IoT environments, research shows that industrial firms have to make a fundamental shift in value creation logic and break free from the value chain perspective of business. Instead they have to embrace a view where value is co-created within ecosystems in both a vertical and a horizontal manner. By exploring the value creation logic of small and medium sized (SME) Swedish industrial machinery manufacturers, this study contributes to a deeper understanding of how manufacturing firms view their value creation processes and how aligned this logic is to the latest research in IoT. The study found that Swedish industrial machine manufacturers do understand the transformative force of IoT-Technologies and see great business opportunities to utilize IoT in their business. The study, however, identified a lack of co-creation and difficulties in embracing an ecosystem perspective. While quick to embrace change on a technical level, respondents still adhere to a firm-centric and linear perspective of value creation, with a strong attachment to the value chain concept. The study suggests that it is not a lack of technical proficiency or engineering know-how, but rather an adherence to goods-dominant logic and attachment to the value chain concept that prevent Swedish SME manufacturers from fully embracing the growing market of industrial IoT. Hence, we see an urgent need for both practitioners and academia to shift their attention from the dazzling potential of cutting-edge technologies to the nitty-gritty business of incorporating co-creation and ecosystem-Thinking into current business practices. © 2020 The authors.

Abstract [en]

It has been shown that large robots can be safely installed for human-robot collaborative assembly cells in experimental setups. It has also been found that these installations require demanding considerations of a significant number of layout and safety parameters. This indicates that successful commercial implementations will require a resource efficient model for production system design that anticipates utilization of large robots in collaborative settings. Experiences from experimental setups have been used to explore a basic model for such production system design, to stimulate a discussion regarding what model characteristics should be tested and validated in future research.

Abstract [en]

Collaborative robot installations often mean man-machine workspace sharing. This mode of operation can lead to reductions of tact time and work space requirements. We have analyzed potential further benefits of man-machine collaboration, where operators and powerful robots share workspace, cooperating when lifting and handling large objects. We found that this mode of operation has the potential to generate economic advantages by reducing the need for manual operators and lifting tools and by offering new opportunities for component logistics.

Abstract [sv]

Hårdare konkurrens, alltmer omfattande miljökrav och allt snabbare teknisk utveckling innebär stora utmaningar och driver företag att söka nya sätt att göra affärer och skapa värde för befintliga och nya kunder. Nya konsumentbeteenden som t ex delningsekonomi (sharing economy) och teknologisk utveckling inom exempelvis digitalisering, additiv tillverkning och förnyelsebar energiproduktion skapar också möjligheter till nya affärer och ökad hållbarhet. Med dessa scenarier på väg att förverkligas kommer det inte att räcka för kommersiella aktörer att bli bättre. De måste ha ett mer radikalt förhållningssätt till sin verksamhet och fråga sig vad som är teoretiskt möjligt när det gäller kostnadseffektivitet och resurssnålhet. Ett naturligt steg är att fokusera på att addera olika former av tjänster till sina varor, som till exempel reservdelar, underhåll och servicekontrakt. Varorna blir plattformar för tjänster som skapar nytta och ökat kundvärde – kallas ofta för tjänstefiering. Det kan också innebära att man förflyttar sig närmare slutkunden i värdekedjan. Men framför allt krävs det att man anammar ett nytt sätt att tänka, en tjänstelogik. Värdelogik/tjänstelogik är ett synsätt där man tar utgångspunkt från värdet kunden försöker skapa för sin kund. Där värde i användning är det centrala till skillnad från varulogik där transaktion av varor i sig är det centrala. Att tjänstefiera ett varufokuserat/tillverkande företag, innebär både möjligheter och utmaningar som bör identifieras, bedömas och hanteras. Att ha tydliga mål och en strategi för sin tjänstefiering är centralt. Övergång från försäljning av varor till försäljning av värde är ett stort steg eftersom det innebär en förändring i verksamheter som rör företagets kärn-verksamhet. Varor som är företagets inkomstkällor blir plötsligt kostnadsposter om kunderna betalar för levererat värde istället för varorna. Detta får radikala konsekvenser för organisation och produktutveckling. Utmaningarna till trots har övergången till värdeförsäljning dock visat sig fungera mycket väl vid ett flertal tillfällen och stora effektiviseringsvinster kan göras när det lyckas. Idag ses tjänstefiering mer som en kontinuerlig process för att skapa en portfölj med erbjudanden med den balans mellan varor, tjänster och affärsmodeller, som på bästa sätt stödjer kundernas värdeskapande processer. Varufokus överges för kundvärdefokus.

Abstract [en]

Programming, safety measures and handling of inflexibility still hinder robot implementation for many applications. However, advancements in several fields such as programming, human–machine-interfaces and safety system technology are about to change this. These advancements could make it possible for operators to collaborate with robots that assist operators at close range, without compromising safety, often referred to as cobot installations. The aim of the project was to produce a picture of how potential economic advantages can be evaluated from installations of cobot cells, to be compared with manual assembly and standard robot installations.

Abstract [en]

Investments in production equipment are made to generate desired production benefit. This work examines how benefit generally is defined and to what extent the benefit is well defined when equipment investments are made. The study revealed that benefit from investments often is unclearly or inconsistently defined, with a narrow system view and often has a weak correlation with benefit for a production system with broader boundaries. This could hamper the possibility to capitalize on industrial trends that indicate a shift in focus, from products, to the benefit utilization of the products can deliver.
