The purpose of this thesis is to examine which factors are the most important to successfully implementing an improvement process, and to examine if subcontracting companies differ from the rest of the companies in the study. Increasing the quality of products and at the same time lowering the costs is often necessary with the pressure from the external environment that many companies are facing today. Many companies are active on a global scale with competitors all over the planet. It is easy to understand that companies need to have an innovative approach, and improve their products, but it is hard to know how and what to change. Upon completion of the initial research phase, a form with questions was created. The composed question sheet was used in an internet based survey. The same question sheet was later used in interviews with 3 different companies. The interview phase provided a chance to ask follow up questions to increase the understanding and help with the analysis. The results from the study were compared with leading literature and similarities were highlighted. The results from the study demonstrate that soft values are the most important factors when implementing an improvement process. Engaged leadership, clear goals and participation from leaders and personnel are the most prominent factors. The differences between subcontracting companies and the other companies in the study are not significant.

The power sector needs to be decarbonised by 2050 to meet the global target for greenhouse gas emission reduction and prevent climate change. With fossil fuels expected to play a vital role in the future energy portfolio and high efficiency penalties related to mature CO2 capture technologies, this research aimed at evaluating the efficiency improvements and alternate operating modes of the coal-fired power plants (CFPP) retrofitted with post-combustion CO2 capture. To meet this aim, process models of the CFPPs, chilled ammonia process (CAP) and calcium looping (CaL) were developed in Aspen Plus® and benchmarked against data available in the literature. Also, the process model of chemical solvent scrubbing using monoethanolamine (MEA) was adapted from previous studies. Base-load analysis of the 580 MWel CFPP retrofits revealed that if novel CAP retrofit configurations were employed, in which a new auxiliary steam turbine was coupled with the boiler feedwater pump for extracted steam pressure control, the net efficiency penalty was 8.7–8.8% points. This was close to the 9.5% points in the MEA retrofit scenario. Conversely, CaL retrofit resulted in a net efficiency penalty of 6.7–7.9% points, depending on the fuel used in the calciner. Importantly, when the optimised supercritical CO2 cycle was used instead of the steam cycle for heat recovery, this figure was reduced to 5.8% points. Considering part-load operation of the 660 MWel CFPP and uncertainty in the process model inputs, the most probable net efficiency penalties of the CaL and MEA retrofits were 9.5% and 11.5% points, respectively. Importantly, in the CaL retrofit scenarios, the net power output was found to be around 40% higher than that of the CFPP without CO2 capture and double than that for the MEA retrofit scenario. Such performance of the CaL retrofit scenario led to higher profit than that of the 660 MWel CFPP without CO2 capture, especially if its inherent energy storage capability was utilised. Hence, this study revealed that CaL has the potential to significantly reduce the efficiency and economic penalties associated with mature CO2 capture technologies.

The Business Process Management (BPM) lifecycle consists of four phases: design and analysis, configuration, enactment, and evaluation - also known as performance analysis and improvement. Performance analysis and improvement of business processes, one of the core phases in the BPM life cycle, is becoming on top of the agenda for many enterprises. An emerging approach to that is to use the business intelligence approaches that attempt to facilitate the analytical capabilities of business process management systems by implementing process-oriented data warehouse and mining techniques. However, little work has been has done on developing core methods and tools for performance analysis and improvement of business processes. In particular, adequate methods, clearly defined steps or instructions that can guide process managers for analyzing and improving processes using process warehouse (PW) are not available. In the absence of such methods, guidelines or clearly defined steps, important steps may be ignored and credible improvements steps cannot be taken. This research addresses the described limitations by developing a method for performance analysis and improvement of business processes. The key feature of the developed method is, it employs business-orientation in the design and utilization of a PW. The method is composed of three steps, building goal-structure, integrating goal-structure with PW, and analyzing and improving business processes. During the first step, a set of top-level performance goals are identified for the process of interest. Subsequently, the identified  goals are decomposed to generate a goal-structure that is aligned with the functional decomposition of the process of interest. The second step describes a technique for integrating the generated goal-structure with PW. The third step describes, a performance estimation model, a decision model and a step by step approach that focuses on utilizing PW for analysis and improvement of business processes. In order to facilitate the use of the proposed method a prototype is developed. The prototype offers a graphical user interface for defining goal structure, integrating goals with PW, and goal-based navigation of PW. In order to evaluate the proposed method, we first develop an evaluation framework and subsequently use it for the evaluation of the proposed method. The framework consists of three components, each representing a type of evaluation. The components are, methodological-structure evaluation, performance-based evaluation and perception-based evaluation. The results of the evaluation show partial support for the methodological structure. However, the results of performance and perception evaluation show promising results of the proposed method. / <p>QC 20121217</p>
