Affärssystem har blivit allt vanligare i organisationer och framhålls av systemleverantörer som ett verktyg för att öka organisationers flexibilitet. Forskning tyder dock på att affärssystem både kan öka och minska flexibiliteten för organisationer. Få empiriska studier har genomförts vad gäller affärssystems påverkan på organisationers flexibilitet och forskningen är splittrad vad gäller affärssystems påverkan på flexibiliteten för organisationer. Syftet med denna uppsats är att illustrera och förklara hur ett affärssystem påverkar flexibilitet i en organisation. För att besvara syftet skapas en analysmodell som syntetiserar tidigare forskning om flexibilitet med en organisatorisk förändringsmodell. En fallstudie utförs genom att anställda intervjuas på Posten Norden AB där affärssystemet SAP används. Uppsatsens undersökning, analys och slutsatser indikerar på att: (1) det arbetsflöde Postens affärssystem tillhandahåller är oflexibelt, (2) affärssystemet möjliggör flexibilitet i kommunikationen (3) affärssystemet hämmar flexibiliteten för vissa arbetsuppgifter på Posten, och (4) affärssystem har en komplex påverkan på flexibilitet i organisationer.

Today, the world is in a continuous process of change, which is conceptualized as globalization. Although the concept is generally related to economy, it affects aspects of human life / i.e. social, cultural, political and so on. The impact of globalization on urban areas requires a special emphasis. Economic development has played a significant role in restructuring the city. Particularly following the 1970s, with the changes in the international economic system, the world has started to transform into a global market and the capital has gained liquidity in this system. Along with the changing system after the industrial restructuring, capital accumulation in developed countries has started to accumulate towards new places. In order to attract capital, the roles of cities are reshaped in the globalization perspective. Globalization led to the formation of the new land uses in order to adapt to the competitive global system, which caused a transformation period of spatial structure. However, these competitive conditions led to unplanned spatial development, especially in the cities of developing countries. This study aims to identify the spatial changes caused by changes in economic conditions, under the impact of globalization and the development process of Maslak, which has been taking place along with the globalization process, and the role of planning system throughout this process in the global city of Istanbul constitute.

In recent years, the trend toward globalization has given rise to rigorous competition for market shares. Businesses have faced the stern demand to swiftly respond to changes in market conditions. They must keep up with environmental situations inside and outside industry, fully integrate various resources of the enterprise, and ponder how to effectively use business resources. Therefore, ERP (enterprise resource planning) systems that integrate the internal value chains of enterprise have received special attention. It is an undisputed fact that an ERP system can integrate internal resources of an enterprise to create for it an overall advantage, improve the flow and elevate the response effectiveness of the enterprise, upgrade information system, and respond to customers¡¦ satisfaction of supply chain management. However, the universal ERP system that is adopted by most enterprises is either costly or difficult to maintain. Moreover, the universal ERP system usually fails to consider special needs of different industries. Therefore, how to ensure a rapid, saving, and effective success through the implementation of ERP systems constitutes the largest challenge faced by enterprises that use such systems. In view of this, this study investigated, from the perspective of ERP supply chain effectiveness of the ¡§differentiation focus strategy¡¨ and the ¡§bowling pin model strategy,¡¨ the impact of the adoption of industry-specific ERP systems on ERP software manufacturers and enterprises that have introduced such a system. Besides, the study used case study approach to conduct a field survey of ERP software manufacturers that have implemented industry-specific ERP system strategy and of four textile and PCB manufacturers that have introduced industry-specific ERP systems with a view to understanding operating models in which industry-specific ERP systems have been successfully introduced and implemented. Through the analysis of this study, it was found that: (1)ERP information manufacturers that adopt industry-specific ERP strategy locating conform to Michael E. Porter¡¦s competitive strategy and differentiation focus strategy, and at the same time verify the bowling pin model theory of Geoffrey A. Moor that technology adopts life cycle. Information manufacturers can enjoy vertical profit-base market advantages of industry-specific ERP and thus avoid competition within industry. As they focus on their specialized field, they not only can strengthen ERP¡¦s professional system functions but also can elevate their effectiveness in follow-up service and maintenance, leading to the reduction of operating costs. From cases of ERP software manufacturers, it was also found that, in areas that special industries cluster, the value of industry-specific ERP in such markets is enlarged. (2)From the perspective of developing industry-specific ERP, after a preliminary development method is used to direct a user to put up concrete industrial characteristic demands and flow, more friendly and suitable operating systems are specified. After being examined and used by a second user, systems are re-examined, revised, and strengthened. After being introduced by a third user and verified and implemented, such systems can become mature, standard industry-specific ERP package systems. (3)From the perspective of enterprise users, adopting the proof of concept method is more practical, accurate, and promising in selecting and evaluating suitable, correct ERP systems. This method can help estimate the outcome after introduction and make it easier to evaluate benefits, for example, keeping project flow schedule and costs under control, implementation and simulation of new enterprise flow schedule. (4)Each industry has professional knowledge and characteristics specific to it. For example, in the case of PCB industry, use rate of base plate material and design and management of engineering data are core professional knowledge of lumber industry. In the case of textile industry, analysis of fabrics, management of characteristics of semi-finished fabrics, integration and automation of process are critical functions essential to competitiveness of this industry. A universal ERP system cannot take care of unique characteristics of various industries. Therefore, only an industry-specific ERP that is specialized in and designed to meet characteristics of a concerned industry can perfectly satisfy the core professional operation of the industry. (5)Because industry-specific ERP systems set the best model of business flow and are concise and suitable, they produce more rapid effectiveness, less impact on organization adjustment, and require smaller investments after being introduced into a business. In view of the preceding findings, the study concluded that the adoption of industry-specific ERP can solidly, effectively, and accurately achieve purposes of ERP systems and can ensure the achievement of potential benefits. At the same time, information manufacturers can obtain vertical profit-base market, enlarging the effect of overall supply value chains.

Intensity modulated arc therapy is a novel treatment technique that has shown great potential to be superior to conventional intensity modulated radiotherapy, both in terms of treatment plan quality as well as treatment delivery. Based on previous literature, a simplified technique called two-step intensity modulated arc therapy (2-step IMAT) was implemented into a treatment planning system. In order to automatically generate treatment plans for this technique, a beam portal shaping method was developed to generate beam segments. A sensitivity analysis was carried out on a geometric phantom to determine optimal parameters for the 2-step IMAT implementation for that particular phantom. The segment weights were optimized using the dose-based and dose-volume-based objective functions. The optimal solution search was based on the gradient-descend algorithm. The dose-based objective function was implemented using a so-called lambda-value-dose-based objective function developed in this work in order to increase both speed and flexibility of the optimization. The successful implementation demonstrated the feasibility of automatic 2-step IMAT treatment planning. A comparison of conventional arc therapy and 2-step IMAT showed improvements in the target dose uniformity by about 50% for both geometric phantom and clinical paraspinal tumor case, whilst also improving the organ sparing. The comparisons between the lambda-value-dose-based and dose-volume-based optimizations showed a speed advantage of the former by a factor of over five in the phantom study. The current beam portal shaping approach can be improved by optimizing the segment width and including multiple organs-at-risk in the segment generation algorithm. Future work will also include the implementation of a stochastic optimization to minimize the chance of getting trapped in local minima during the segment weight optimization. In summary, the work of this research showed that the automatic 2-step IMAT planning is a viable technique that can result in highly conformal plans while keeping the treatment planning and delivery simple and straightforward.

Section 38 of the Local Government Municipal Systems Act (32 /2000) tasks municipalities to establish a performance management system that corresponds with resources, circumstances, objectives, indicators and targets as stated in the municipalities integrated development plan. The Act further states that a culture of performance management should be promoted amongst all stakeholders. Thus, the Emfuleni Local Municipality (ELM) has the statutory obligation to provide an effective and efficient people cantered administration that will ensure quality and sustainable service delivery. The Emfuleni Local Municipality tends to have a culture of non - performance or low service delivery which is prevalent amongst employee or personnel. Performance Management System (PMS) is the service delivery tool, which in this regard is designed to specifically enhance service delivery among the communities. The objective of this study was to assess the effects of implementation of PMS by officials and employees to ensure whether there is effective, efficient and economic delivery of services at ELM. For the purpose of this study, the hypothesis was formulated that due to the inability of integrating IDP planning system with performance management and service delivery, Emfuleni Local Municipality is ineffective in successful implementation of the IDP. To test the validity or otherwise of the hypothesis, use was made of theoretical review of literature on PMS as a tool for enhancing service delivery at ELM. Further there was an empirical research methodology of open - ended questionnaire that was used to test attitudes and perceptions of municipal officials and employees and effectiveness of implementation of PMS at ELM. It was found among others, that: there is lack of experience and proper training among municipal officials at ELM, ELM employs inexperienced and not well trained employee in the management level, balance scorecard remains a valid instrument at Emfuleni's disposal to influence commitment to the delivery of service, management at ELM did not market PMS effectively to the staff, the PMS has positive influence on production, the political and administrative accountability in a democratic government cannot be dissociated from each other. The study ends with recommendations for action to be taken by management of ELM. / Thesis (M. Development and Management)--North-West University, Vaal Triangle Campus, 2009.
