Factory-in-a-Box : an Enabler for Flexibility in Manufacturing Systems
- 2006
-
Licentiate thesis (other academic/artistic)abstract
- AT PRESENT, many markets are characterized by a fast pace of change, as well as a high internationally enlarged competition. Since the conception of Mass Customization emerged in the late 1980´s, many companies within the manufacturing industry have been striving to fulfill this vision by increasing the flexibility within their manufacturing system. However, although there are many manufacturing theories that describe theoretical solutions to mass customization, but there is still a lack of practical enablers that can realize the conception.In January 2005, the Swedish Foundation for Strategic Research started the project Factory-in-a-Box. There, the key characteristic is to realize is the concept of modular production units that are flexible, mobile and quick to ramp-up. This licentiate thesis is a part of the Factory-in-a-Box project, and its objective is to investigate if and how the Factory-in-a-box concept is an enabler to realize flexibility in manufacturing systems.The outcome of this research work indicates that the Factory-in-a-Box concept is a plausible solution that goes in line with previous research and future challenges within the manufacturing industry. The Factory-in-a-Box concept offers possibilities for a more flexible and responsive manufacturing system, which also unwrap new business possibilities, increased automation, and entering new markets. To succeed in implementing the Factory-in-a-Box concept in a manufacturing system some key generic requirements have been identified.The research project concludes that mobile manufacturing systems in general and the Factory-in-a-Box concept in particular offer new possibilities to the manufacturing industry. Also, the concept is not limited to the manufacturing industry, there are a wide range of applications where the concept could be useful, for example within the construction industry.

Informationsdesign i tillståndsövervakning : En studie av ett bildskärmsbaserat användargränssnitt för tillståndsövervakning och tillståndsbaserat underhåll
- 2010
-
Doctoral thesis (other academic/artistic)abstract
- This research concerns the information design and visual design of graphical user interfaces (GUI) in the condition monitoring and condition-based maintenance (CBM) of production equipment. It also concerns various communicative aspects of a GUI, which is used to monitor the condition of assets. It applies to one Swedish vendor and its intentions to design information. In addition, it applies to the interaction between the GUI and its individual visual elements, as well as the communication between the GUI and the users (in four Swedish paper mills).The research is performed as a single case study. Interviews and observations have been the main methods for data collection. Empirical data is analyzed with methods inferred to semiotics, rhetoric and narratology. Theories in information science and regarding remediation are used to interpret the user interface design.The key conclusion is that there are no less than five different forms of information, all important when determining the conditions of assets. These information forms include the words, images and shapes in the GUI, the machine components and peripherals equipment, the information that takes form when personnel communicate machine conditions, the personnel’s subjective associations, and the information forms that relate to the personnel's actions and interactions.Preventive technicians interpret the GUI-information individually and collectively in relation to these information forms, which influence their interpretation and understanding of the GUI information. Social media in the GUI makes it possible to represent essential information that takes form when employees communicate a machine’s condition. Photographs may represent information forms as a machine’s components, peripherals, and local environment change over time. Moreover, preventative technicians may use diagrams and photographs in the GUI to change attitudes among the personnel at the mills and convince them, for example, of a machine’s condition or the effectiveness of CBM as maintenance policy.

Managing Collaborative Product Development : A Model for Identifying Key Factors in Product Development Projects
- 2007
-
Doctoral thesis (other academic/artistic)abstract
- The increasing complexity of products and systems today has forced new processes, methods, and tools for managing the development of products. It has also forced the development of complex organisations and diverse relationships among functions and peoples within product development organisations. This implies a need for integrated processes. There is a need to study collaborative product development (CPD) from a holistic perspective, where internal as well as external collaboration are studied as integrated parts of CPD settings.Thus, the main purpose of the research project is to facilitate the efficient execution of collaborative product development projects in the manufacturing industry. Further, the objective is to provide a supporting model for analysing and setting up projects in CPD settings. This will enable successful product development in terms of lowering costs, increasing the perceived quality of the product, and improving the timing to market. The focus is on the CPD projects, linking internal and external collaboration.A systems approach is applied to the research project to obtain the holistic view needed for addressing the CPD setting. Within the research project, case study research is used as the primary method when gathering empirics. The results from four case studies are tested and analysed in a concluding survey.The results show that shared visions and goals, the decision-making process, tools and methods, requirement management, and involvement are the most important factors for efficient CPD projects. If the collaborative complexity is high, the first four factors are especially important. The results are presented in a model to be used as a support when setting-up and managing CPD projects. The model is applied together with a process for managing CPD projects.

Coping with decisions on deviations in complex product development projects
- 2012
-
Doctoral thesis (other academic/artistic)abstract
- A strong need for resource efficiency within manufacturing companies have been driven extensively through pro-active planning and methods which have naturally resulted in an increased amount of strong couplings between product development projects, their activities, and resources. These strong couplings mean a high level of complexity where deviations are likely to occur on a regular basis which can spread quickly and have far reaching consequences. Praxis related to treatment of such deviations in product development projects has not been widely discussed. The subsequent question is therefore How are decisions on managing deviations made in practice?A Practice approach has been adopted in this research and led on to the use of context sensitive research methods in order to collect relevant data. The main amount of data has been gathered through one year of participant observations and document retrieval in a product development project. Also, a large amount of interviews have been used as a method for collecting data.38 deviations have been analysed through the identification of praxis which has been primarily analysed by three theories. The first theory, decision roles, has been used to clarify the different types of uncertainties people within complex product development projects need to manage in practice. The second theory, loosely coupled systems, shows how temporary organizing by loose couplings enables parallel management of both planned and unplanned activities when deviations occur. The third theory, Sensemaking, have been used to characterise processes related to different types of uncertainties.Conclusions are drawn regarding how people acts related to deviations are directly dependent on the types of uncertainties of the context as well as the situation itself. Uncertainties regarding choices, responsibilities, mobilization, and legitimization combined with the temporary organization leads to certain praxis patterns. The patterns can be used by project managers and other decision makers as a way of discussing temporary organization and how process emerge within the organization today, and how they would like resulting processes to be managed when deviations occur.

-
Journal article (peer-reviewed)abstract
- This paper presents the results of a case study aimed at investigating how decisions are made on managing deviations in complex product development projects. The results are based on the analysis of data collected from participant observations, as well as interviews with project managers from seven large manufacturing companies. The data is analysed according to four types of sensemaking processes. This research examines why these processes are used in different situations and further explore their characteristics and at their relationship with the different roles decisions play in organizations. The factors driving controlled and uncontrolled sensemaking are also examined. This research contributes to knowledge of how project managers use different praxes to manage deviations in complex, socially and politically sensitive environments. The results can be used by decision makers within complex product development in order to assist them in managing deviations, proactively as well as reactively.

Conference paper (peer-reviewed)abstract
- Product development projects need to be managed in a timely and efficient manner in the present competitive business environment. The authors of this work argue that the commonly used product development models do not fully meet this demand, and the decision-making process needs to be made explicit. This work mainly focuses on the product development process. Two companies were studied using case study research. The aim of the case study was to identify key factors affecting the decision-making process in product development. The type of collaboration used in these two companies was also investigated in order to identify the influence it had on the decision-making process of each. The two companies had different views of the decision-making process which were related to their level of development process knowledge. Common factors affecting the decision-making process in product development were divided into ten categories: (1) Handling of requirements, (2) Experience of projects, (3) Organizational aspects, (4) Project management, (5) Top management, (6) Knowledge, (7) Risk management, (8) Information systems, (9) Communication, and (10) Change management.
