It is generally accepted that between 70 and 80% of manufacturing costs can be attributed to design. Nevertheless, it is difficult for the designer to estimate manufacturing costs accurately, especially when alternative constructions are compared at the conceptual design phase, because of the lack of cost information and appropriate tools. In general, previous reports concerning optimisation of a welded structure have used the mass of the product as the basis for the cost comparison. However, it can easily be shown using a simple example that the use of product mass as the sole manufacturing cost estimator is unsatisfactory. This study describes a method of formulating welding time models for cost calculation, and presents the results of the models for particular sections, based on typical costs in Finland. This was achieved by collecting information concerning welded products from different companies. The data included 71 different welded assemblies taken from the mechanical engineering and construction industries. The welded assemblies contained in total 1 589 welded parts, 4 257 separate welds, and a total welded length of 3 188 metres. The data were modelled for statistical calculations, and models of welding time were derived by using linear regression analysis. Themodels were tested by using appropriate statistical methods, and were found to be accurate. General welding time models have been developed, valid for welding in Finland, as well as specific, more accurate models for particular companies. The models are presented in such a form that they can be used easily by a designer, enabling the cost calculation to be automated.

Työn tavoitteena oli arvioida ja selvittää toimittajasuhteeseen vaikuttavia tekijöitä JOT Automation Group Oyj.n ja sen alihankkijoiden välisessä yhteistyössä ja muodostaa yrityksen kilpailukykyä parantava toimittaja-arviointiprosessi. Työssä keskityttiin tarkastelemaan yleisillä materiaali- ja komponenttimarkkinoilla toimivia toimittajia elektroniikkateollisuuden tuotantojärjestelmien valmistuksessa. Ensin tutustuttiin toimittajasuhdetta ja sen arviointia käsitelleeseen kirjallisuuteen. Teorian tueksi tehtiin haastatteluja ja kartoitettiin ensisijaisia tarpeita ja tavoitteita arviointiprosessille. Valmis prosessi testattiin käytännössä kahden eri case-esimerkin avulla. Prosessista muodostui kahteen eri työkaluun jakautunut kokonaisuus, joista auditointi arvioi toimittajan kyvykkyyttä vastatta sille asetettuihin vaatimuksiin. Toimittajan suorituskyvyn mittaaminen puolestaan testaa ja vertaa jatkuvasti toiminnan todellista tasoa auditoinnissa saatuihin tuloksiin. Työ sisältää selvityksen ja ohjeistuksen toimittaja-arviointiprosessin käytöstä. Prosessin käyttö alentaa toimittajaan kohdistuvaa materiaalien saatavuuteen ja hankintaan liittyviä riskejä. Esimerkeistä saadut kokemukset osoittivat, että prosessin avulla päästään pureutumaan tärkeisiin ydinalueisiin ja kehittämään niitä sekä toimittajalle, että ostajayritykselle edullisella tavalla. Toimittaja-arviointiprosessista kehittyy toimintatapa yrityksen ja sen toimittajan välisen suhteen ylläpitämiseksi.

Työn tavoitteena on kuvata hissin ovien tuotekonfigurointiprosessia sekä SAP R/3 tuotekonfiguraattorin käyttöönoton aiheuttamia vaikutuksia. Työssä kuvataan myös uuden tuotekonfiguraattorin kehitystä, testausta, käyttöönottoa sekä pitkäaikaishallintaa. Tuotekonfigurointi on tehokas tapa toteuttaa massaräätälöintiä. Sen tarkoituksena on yhdistää massatuotannon ja asiakaskohtaisen tuotannon etuja tarjoamalla asiakkaille räätälöityjä, esisuunniteltuihin komponentteihin ja ennalta määrättyyn konfigurointimalliin perustuvia tuotteita. Näitä tuotteita tuotetaan konfigurointiprosessissa. Tämä prosessi voi olla erittäin monimutkainen ja altis virheille, joten sen tueksi on kehitetty tuotekonfiguraattoreita. Tuotekonfiguraattorit voivat tehostaa konfigurointiprosessia merkittävästi. KONE on valmistanut konfiguroitavia tuotteita useita vuosikymmeniä ja se on käyttänyt prosessien tukemiseen useita eri konfiguraattoreita. Näin ollen uuden konfiguraattorin käyttöönoton vaikutusten ei oleteta olevan niin dramaattisia kuin otettaessa konfiguraattoria käyttöön ensimmäisen kerran. Uudella konfiguraattorilla on kuitenkin useita vaikutuksia tuotteen hallintaan, konfigurointiprosessiin, tietojärjestelmiin, alihankkijoihin sekä asiakkaisiin. Konfiguraattorin käyttöönoton vaikutuksia tehostaa projektin liittyminen ERP järjestelmän käyttöönottoon

The objective of the thesis was to create a framework that can be used to define a manufacturing strategy taking advantage of the product life cycle method, which enables PQP enhancements. The starting point was to study synkron implementation of cost leadership and differentiation strategies in different stages of the life cycles. It was soon observed that Porter’s strategies were too generic for the complex and dynamic environment where customer needs deviate market and product specifically. Therefore, the strategy formulation process is based on the Terry Hill’s order-winner and qualifier concepts. The manufacturing strategy formulation is initiated with the definition of order-winning and qualifying criteria. From these criteria there can be shaped product specific proposals for action and production site specific key manufacturing tasks that they need to answer in order to meet customers and markets needs. As a future research it is suggested that the process of capturing order-winners and qualifiers should be developed so that the process would be simple and streamlined at Wallac Oy. In addition, defined strategy process should be integrated to the PerkinElmer’s SGS process. SGS (Strategic Goal Setting) is one of the PerkinElmer’s core management processes. Full Text: Null

Sales configurators are essential tools for companies that offer complicated case specifically crafted products for customers. Most sophisticated of them are able to design an entire end product on the fly according to given constraints, calculate price for the offer and move the order into production. This thesis covers a sales configurator acquisition project in a large industrial company that offers cranes for its customers. The study spans the preliminary stages of a large-scale software purchase project starting from the specification of problem domain and ending up presenting the most viable software solution that fulfils the requirements for the new system. The project consists of mapping usage environment, use cases, and collecting requirements that are expected from the new system. The collected requirements involve fitting the new sales system into enterprise application infrastructure, mitigating the risks involved in the project and specifying new features to the application whilst preserving all of the admired features of the old sales system currently used in the company. The collected requirements were presented to a number of different sales software vendors who were asked to provide solution suggestions that would fulfil all the demands. All of the received solution proposals were exposed to an evaluation to determine the most feasible solutions, and the construction of evaluation criteria itself was a part of the study. The final outcome of this study is a short-list of the most feasible sales configurator solutions together with a description of how software purchase process in large enterprises work, and which aspects should be paid attention in large projects of similar kind.

The bachelor’s thesis concentrates on the innovativeness in the construction industry. The purpose of the thesis is to define the innovation as a concept reflected on a context of the construction industry. The second objective is to examine how the construction companies could foster and increase the innovativeness. The third objective was to find out tools, methods and phases of the front-end of the innovation process. The construction industry is often considered as a traditional and an old-fashioned manufacturing industry. The innovation or the innovativeness rarely linked to the construction industry. Productivity is a common problem in the construction industry. The construction industry needs to increase the productivity to compete in a globalized world. The productivity can be increased by the innovation. The thesis based on a literature review. The findings from the literature include a description of the innovation as a concept, the innovative culture and the innovation process as a context of the construction industry. The phases of the front-end of the innovation process were explained. Customers centered approach was taken into account in the innovation process. The required tools and methods for managing the front-end of the innovation process were illustrated. The thesis ensures the importance of the innovation facing challenges of the construction industry. Managing the front-end of the innovation is the most important aspect to stand out from the less innovative companies. To take a full advantage of the innovation companies cannot fear of changes. The innovation process requires a full support of the top management of the company. Taking into consideration a theoretical aspect of the thesis a further research is required to respond practical needs of the company. Tools and methods should be considered according the company’s needs and activities.

In recent times of global turmoil, the need for uncertainty management has become ever momentous. The need for enhanced foresight especially concerns capital-intensive industries, which need to commit their resources and assets with long-term planning horizons. Scenario planning has been acknowledged to have many virtues - and limitations - concerning the mapping of the future and illustrating the alternative development paths. The present study has been initiated to address both the need of improved foresight in two capital-intensive industries, i.e. the paper and steel industries and the imperfections in the current scenario practice. The research problem has been approached by engendering a problem-solving vehicle, which combines, e.g. elements of generic scenario process, face-to-face group support methods, deductive scenario reasoning and causal mapping into a fully integrated scenario process. The process, called the SAGES scenario framework, has been empirically tested by creating alternative futures for two capital-intensive industries, i.e. the paper and steel industries. Three scenarios for each industry have been engendered together with the identification of the key megatrends, the most important foreign investment determinants, key future drivers and leading indicators for the materialisation of the scenarios. The empirical results revealed a two-fold outlook for the paper industry, while the steel industry future was seen as much more positive. The research found support for utilising group support systems in scenario and strategic planning context with some limitations. Key perceived benefits include high time-efficiency, productivity and lower resource-intensiveness. Group support also seems to enhance participant satisfaction, encourage innovative thinking and provide the users with personalised qualitative scenarios.

The objective of this thesis is to examine the factors that have an impact on the location decision of new manufacturing site and to create the relative order of importance of these factors by analytic hierarchy process (AHP). The decision making process especially related to the location selection and the measurement of the location factors are also examined. In theoretical part the character of decision making process and the relevant methods are introduced. Based on the previous studies of other researchers, the location factors are examined and the main research method, analytic hierarchy process, is also introduced. The empirical part of the study mainly follows the phases of decision making process and is emphasized on the main stages of analytic hierarchy process; building the hierarchy, defining the priorities and analyzing the results. The hierarchy is constructed from seven main criteria which all have several sub criteria. The evaluation of the hierarchy is implemented at the group decision making –laboratory and there can be seen significant differences between the importance of criteria. The final stage in the study is to create the appropriate measurement scales to the chosen criteria.

In this thesis, the purpose was to find the cost distribution of the screen dryer and the largest cost factors. The hot section of the screen dryer was revealed as the biggest cost factor, so composing new cost efficient solutions were directed to it. DFMA (Design for Manufacture and Assembly) was chosen to help the design process. DFMA is a product design strategy developed for taking manufacturing and assembly costs into account at the early stages of the design process. In the theory part of the thesis, other methods of economical design and tools needed for estimating manufacturing costs are introduced. In the empirical part, the hot section of the screen dryer was divided into sub-assemblies and their manufacturing costs were estimated. The design propositions were directed to the self-manufactured assemblies and parts. The new manufacturing costs were calculated for the developed propositions. Lastly, the most cost efficient solutions were summarized. The savings on the self-manufactured assemblies were about 40 %, which was about 13 % of the combined total costs of the hot section.

A company’s capability to map out its cost position compared to other market players is important for competitive decision making. One aspect of cost position is direct product cost that illustrates the cost efficiency of a company’s product designs. If a company can evaluate and compare its own and other market players’ direct product costs, it can implement better decisions in product development and management, manufacturing, sourcing, etc. The main objective of this thesis was to develop a cost evaluation process for competitors’ products. This objective includes a process description and an analysis tool for cost evaluations. Additionally, process implementation is discussed as well. The main result of this thesis was a process description consisting of a sixteen steps process and an Excel based analysis tool. Since literature was quite limited in this field, the solution proposal was combined from many different theoretical concepts. It includes influences from reverse engineering, product cost assessment, benchmarking and cost based decision making. This solution proposal will lead to more systematic and standardized cost position analyses and result in better cost transparency in decision making.

This Master’s thesis addresses different approaches using which a foreign IT company could enter Russian manufacturing industry with its enterprise information systems and IT services. In order to define the most suitable market entry approach, several aspects related to Russian manufacturing enterprises are studied. These aspects include challenges of doing ICT business with the previously mentioned enterprises, their perception of ICT role and their ICT preferences, as well as their buying behavior related to acquisition of information systems (IS). The study results show that there are several challenges that can be faced by a foreign IT vendor when starting conducting ICT business with Russian manufacturing enterprises. The results also show that Russian manufacturing industry is still rather immature in sense of business process automation, and its IT buying behavior is rather specific and complicated. The results suggest that an efficient way to approach these enterprises is through a network of trusted partners that consists of reliable Russian IS integrators and business consultants having established connections to Russian manufacturing companies and possessing the needed competence.

The purpose of this thesis is to examine the level of customer consciousness of the production process employees in a steel factory and to investigate the methods of internal marketing in order to propose development practices to enhance the customer consciousness of the case company employees. The significance of the level of customer consciousness is discussed and practices already implemented affecting the level of customer consciousness in the company are examined. The literature review gives an insight to the role of customer consciousness in the CRM philosophy of a manufacturing company and examines the means of internal marketing in enhancing customer consciousness. In the empirical part of the study, the level and significance of customer consciousness is determined by conducting individual and focus group interviews. The interviews are also used to examine the practices that could function in enhancing the customer consciousness of the employees. Development suggestions to improve the level of customer consciousness in the production process are given based on the results. The level of customer consciousness is at a poor level in the production process and influences above all on work motivation and job satisfaction, but possibly on customer satisfaction as well. The enhancement of customer consciousness in the production process should be done e.g. by ensuring the distribution of right knowledge coherently to all of the employees, gathering large customer reference database to exploit in work and in training, using visual illustration in presenting the customer information, training proactively and letting the employees to participate in the customer oriented development activities. Customer satisfaction focused reward system can be considered.
