Повний текст джерелаENGLISH ABSTRACT: A difficult subclass of engineering optimisation problems is the class of optimisation problems which are dynamic and stochastic. These problems are often of a non-closed form and thus studied by means of computer simulation. Simulation production runs of these problems can be time-consuming due to the computational burden implied by statistical inference principles. In multi-objective optimisation of engineering problems, large decision spaces and large objective spaces prevail, since two or more objectives are simultaneously optimised and many problems are also of a combinatorial nature. The computational burden associated with solving such problems is even larger than for most single-objective optimisation problems, and hence an e cient algorithm that searches the vast decision space is required. Many such algorithms are currently available, with researchers constantly improving these or developing more e cient algorithms. In this context, the term \e cient" means to provide near-optimised results with minimal evaluations of objective function values. Thus far research has often focused on solving speci c benchmark problems, or on adapting algorithms to solve speci c engineering problems. In this research, a multi-objective optimisation algorithm, based on the cross-entropy method for single-objective optimisation, is developed and assessed. The aim with this algorithm is to reduce the number of objective function evaluations, particularly when time-dependent (dynamic), stochastic processes, as found in Industrial Engineering, are studied. A brief overview of scholarly work in the eld of multiobjective optimisation is presented, followed by a theoretical discussion of the cross-entropy method. The new algorithm is developed, based on this information, and assessed considering continuous, deterministic problems, as well as discrete, stochastic problems. The latter include a classical single-commodity inventory problem, the well-known buffer allocation problem, and a newly designed, laboratory-sized recon gurable manufacturing system. Near multi-objective optimisation of two practical problems were also performed using the proposed algorithm. In the rst case, some design parameters of a polymer extrusion unit are estimated using the algorithm. The management of carbon monoxide gas utilisation at an ilmenite smelter is complex with many decision variables, and the application of the algorithm in that environment is presented as a second case. Quality indicator values are estimated for thirty-four test problem instances of multi-objective optimisation problems in order to quantify the quality performance of the algorithm, and it is also compared to a commercial algorithm. The algorithm is intended to interface with dynamic, stochastic simulation models of real-world problems. It is typically implemented in a programming language while the simulation model is developed in a dedicated, commercial software package. The proposed algorithm is simple to implement and proved to be efficient on test problems.
AFRIKAANSE OPSOMMING: 'n Moeilike deelklas van optimeringsprobleme in die ingenieurswese is optimeringsprobleme van 'n dinamiese en stogastiese aard. Sulke probleme is dikwels nie-geslote en word gevolglik met behulp van rekenaarsimulasie bestudeer. Die beginsels van statistiese steekproefneming veroorsaak dat produksielopies van hierdie probleme tydrowend is weens die rekenlas wat genoodsaak word. Groot besluitnemingruimtes en doelwitruimtes bestaan in meerdoelige optimering van ingenieursprobleme, waar twee of meer doelwitte gelyktydig geoptimeer word, terwyl baie probleme ook 'n kombinatoriese aard het. Die rekenlas wat met die oplos van sulke probleme gepaard gaan, is selfs groter as vir die meeste enkeldoelwit optimeringsprobleme, en 'n doeltre ende algoritme wat die meesal uitgebreide besluitnemingsruimte verken, is gevolglik nodig. Daar bestaan tans verskeie sulke algoritmes, terwyl navorsers steeds poog om hierdie algoritmes te verbeter of meer doeltre ende algoritmes te ontwikkel. In hierdie konteks beteken \doeltre end" dat naby-optimale oplossings verskaf word deur die minimum evaluering van doelwitfunksiewaardes. Navorsing fokus dikwels op oplossing van standaard toetsprobleme, of aanpassing van algoritmes om 'n spesi eke ingenieursprobleem op te los. In hierdie navorsing word 'n meerdoelige optimeringsalgoritme gebaseer op die kruis-entropie-metode vir enkeldoelwit optimering ontwikkel en geassesseer. Die mikpunt met hierdie algoritme is om die aantal evaluerings van doelwitfunksiewaardes te verminder, spesi ek wanneer tydafhanklike (dinamiese), stogastiese prosesse soos wat dikwels in die Bedryfsingenieurswese te egekom word, bestudeer word. 'n Bondige oorsig van navorsing in die veld van meerdoelige optimering word gegee, gevolg deur 'n teoretiese bespreking van die kruis-entropiemetode. Die nuwe algoritme se ontwikkeling is hierop gebaseer, en dit word geassesseer deur kontinue, deterministiese probleme sowel as diskrete, stogastiese probleme benaderd daarmee op te los. Laasgenoemde sluit in 'n klassieke enkelitem voorraadprobleem, die bekende buffer-toedelingsprobleem, en 'n nuut-ontwerpte, laboratorium-skaal herkon gureerbare vervaardigingstelsel. Meerdoelige optimering van twee praktiese probleme is met die algoritme uitgevoer. In die eerste geval word sekere ontwerpparameters van 'n polimeer-uittrekeenheid met behulp van die algoritme beraam. Die bestuur van koolstofmonoksiedbenutting in 'n ilmeniet-smelter is kompleks met verskeie besluitnemingveranderlikes, en die toepassing van die algoritme in daardie omgewing word as 'n tweede geval aangebied. Verskeie gehalte-aanwyserwaardes word beraam vir vier-en-dertig toetsgevalle van meerdoelige optimeringsprobleme om die gehalte-prestasie van die algoritme te kwanti seer, en dit word ook vergelyk met 'n kommersi ele algoritme. Die algoritme is veronderstel om te skakel met dinamiese, stogastiese simulasiemodelle van regtew^ereldprobleme. Die algoritme sal tipies in 'n programmeertaal ge mplementeer word terwyl die simulasiemodel in doelmatige, kommersi ele programmatuur ontwikkel sal word. Die voorgestelde algoritme is maklik om te implementeer en dit het doeltre end gewerk op toetsprobleme.

Повний текст джерелаENGLISH ABSTRACT: Some concepts of manufacturing on their own playa decisive role in manufacturing like Integration, Intelligence and Remote Monitoring. They have been tried and tested with great success in various applications in manufacturing. However, very little has been written on the synergy that is created when all three is deployed in one system. It is the aim of this work to survey the attributes of each of these key concepts, to compare them on the grounds of applicability and to study the effects when combined into one system. Final conclusions are made after the hypotheses have been validated with the aid of an experimental model. The first objective of this work is to show how many techniques such as expert systems, fuzzy logic, neural networks and genetic algorithms are used to enable systems to perform intelligently. It is accepted that the competitiveness, growth and profitability of a company in future may depend on the level of its system intelligence. This is so because an intelligent system is able to act appropriately under rapidly changing conditions of customer customisation and demands on quicker throughputs. A further objective of this work is to show how integration adds the element of synergy to a system. This is done by showing several ways of achieving integration by non-technological means like departmental consolidation, plant consolidation, product rationalisation, more flexible working practices, etc. There are as many options for integration by technical means as well, ranging from group technology to process or transfer lines, and from flexible automation such as robots through to hard automation using special-purpose machinery and transfer lines. The third objective is to show how remote monitoring enhances the capabilities of manufacturing systems by synergising with the other two key concepts. With the technology of intelligent manufacturing and integration, larger and more complex manufacturing systems are becoming a reality. However, the danger exists that the shop floor machine tools remain isolated islands of automation. Plant machinery needs to be networked into the enterprise-wide information system. The ability to monitor a variety of process parameters and alert plant staff to changing conditions can greatly reduce downtime. This lack of connectivity therefore represents a huge constraint as far as productivity is concerned. For this reason, there is a great interest to study remote monitoring, analysis and diagnostic systems for application in modem manufacturing. The major contribution of this work is to study the synergy that is created by combining the three key concepts into one system and to validate the findings with the aid of the experimental model. The meaning of validation is to make legally valid; to grant official sanction to; to confirm the validity of something or to declare something as true. To validate is to support or corroborate a theory on a sound or authoritative basis by experiments designed to show a hypothesis as being true. The components of the validation model are a neural network, a simulator, a decision evaluator or critic, and a teacher. The neural network is used to make the decisions. Its inputs are the system parameters and its outputs are a vector of values between 0 and 1, the highest value indicates the decision being made (winner takes all). The simulator executes the decision it obtains from the network and thus changes the state of the system. The evaluator looks at how the system changed due to the decision made by the network and decides whether it was a good or a bad decision. The teacher then adjusts the output of the network accordingly and trains the network with the adjusted outputs. The results of the validation experiments show that intelligence is used to train the model, integration is achieved by combining the elements of the model with the mobile robot and remote monitoring is done by the model to analyse the condition of the system and to react accordingly. The main objective of this work is clearly met in that synergy was shown to be created by the three key concepts.
AFRIKAANSE OPSOMMING: Aspekte soos Integrasie, Intelligensie en Afstandsmonitering speel 'n deurslaggewende rol in vervaardiging en is al op hulle eie met groot sukses in vele toepassings gebruik. Daar is egter nog nie veel aangeteken oor die sinergie wat ontstaan wanneer hulle tesame in een stelsel gebruik word nie. Dit is die doel van hierdie werk om die kenmerke van elk van hierdie sleutel aspekte na te vors, dit op grond van toepaslikheid met mekaar te vergelyk en die uitwerking te bestudeer wanneer hulle in een stelsel saamgevoeg word. Nadat die hipoteses met behulp van 'n eksperimentele model gevalideer is, word finale gevolgtrekkings gemaak. Die eerste doelwit van hierdie werk is om aan te toon dat verskeie tegnieke soos genetiese algoritmes en neurale netwerke gebruik word om stelsels meer kundig te laat optree. Dit word aanvaar dat die toekomstige mededingendheid en groei van ondernemings mag afhang van die stelsel intelligentheidsvlak. Dit is omdat intelligente stelsels gepas kan optree onder snel-veranderende omstandighede. 'n Verdere doelwit is om aan te toon hoe integrasie sinergie kan toevoeg tot 'n stelsel. Dit word gedoen deur verskeie metodes te bespreek van hoe om integrasie op 'n nie-tegniese vlak te bewerkstellig. Die tegniese metodes van integrasie word ook bespreek en sluit tegnieke soos groeptegnologie, aanpasbare outomatisasie en robotika in. Die derde doelwit is om aan te toon hoe afstandsmonitering as sleutel aspek die ander twee sleutel aspekte kan versterk. Die tegnologië van intelligente vervaardiging en integrasie maak die skepping van groter en meer kompleks vervaardigingstelsels nou moontlik. Die gevaar bestaan egter dat hierdie masjiene slegs eilande van outomatisasie sal bly indien hulle nie met behulp van netwerke in die onderneming se inligtingstelselopgeneem word nie. Die vermoë om prosesveranderinge te monitor kan lei tot verminderde staantyd van masjiene en kan dus produktiwiteit verhoog. Om hierdie redes is die toepassing van afstandsmonitering en -diagnosering belangrik vir toepassing in vervaardiging. Die belangrikste bydrae van hierdie werk is die studie van die sinergie wat ontstaan wanneer die drie sleutel aspekte in een stelsel gekombineer word en om die bevindinge te valideer met behulp van 'n eksperimentele model. Om te valideer beteken om iets geldig te verklaar of om die geldigheid van iets te bevestig. Dit beteken verder om 'n teorie te ondersteun of te staaf op 'n grondige en deskundige basis met behulp van eksperimente. Die validasie model bestaan uit 'n neurale netwerk, 'n simulator, 'n besluitevalueerder of beoordelaar, en 'n onderwyser (terugvoerder). Die neurale netwerk neem die besluite met die stelselparameters as inset en die uitset 'n vektor met waardes tussen 0 en 1. Die simulator voer die besluit uit en verander so die toestand van die stelsel. Die evalueerder bepaal hoe die stelsel verander het as gevolg van die besluit en bepaalook of dit 'n goeie of slegte besluit was. Die onderwyser verstel dan die uitset van die netwerk dienooreenkomstig en lei die netwerk op met die verstelde uitsette. Die resultate van die validasie eksperiment toon aan dat intelligensie gebruik word om die modelop te lei, integrasie behaal word deur die elemente van die model te kombineer met die mobiele robot en afstandsmonitering toegepas word deur die toestand van die stelsel te monitor en te analiseer. Die hoofdoelwit van hierdie werk word dus duidelik behaal deur die beskrywing van die sinergie wat ontstaan deur die kombinasie van die drie sleutel aspekte.

Повний текст джерелаENGLISH ABSTRACT: Performance management systems are integral to many organisations. On all levels of management such performance measurements are used to drive a desired behaviour and business units, departments, as well as individuals are rewarded for meeting or exceeding set targets. In large silo-structured organisations, divisions are particularly focused on their own targets and responsibilities. This may result in a diminished view of the effect their strategies and processes may have on overall stakeholder value. These divisions execute strategies to enhance the achievement of their own goal. The execution of these strategies sometimes hampers other divisions in meeting their goals. The net effect of this hampering may result in reduced stakeholder value. A mechanism is needed through which organisational divisions can evaluate the systemic environment, in order to identify hampering processes. The case may be that their processes are hampering other divisions, or that their processes as such are being hampered. The main objective of this research study was to develop such a mechanism. This mechanism emerged through a framework which can be used during investigations of hampering processes. Such investigation is conducted by following six predefined steps to guide the investigator in identifying the hampering factors. This framework was developed by combining primarily three disciplines: Systems thinking, Performance evaluation and Supplier perceived value. The evaluation framework was validated through three case studies. In all of the cases the framework delivered the expected result. It is thus concluded that organisations can apply the framework to help identify systemic environmental factors that may hamper business processes.
AFRIKAANSE OPSOMMING: Prestasiebestuurstelsels maak ʼn integrale deel uit van die meeste organisasies. Prestasiebeoordeling word op alle vlakke van bestuur ingespan om die verlangde gedrag aan te moedig. Sake-eenhede, departemente en individue word vergoed indien hulle die gestelde doelwitte haal of oorskry. In groot silo-gedrewe organisasies is afdelings grootliks gefokus op hulle eie verantwoordelikhede en om hulle eie doelwitte te bereik. Gevolglik verminder dit soms die uitwerking wat die uitkomste van hulle strategieë en prosesse het op die belanghebbendes van die organisasie. Hierdie afdelings voer dus strategieë uit om hulle eie doelwitte te behaal. Soms verhinder hierdie strategieë ander afdelings om hulle doelwitte te bereik. Die basiese effek hiervan kan wees dat minder waarde aan die belanghebbendes deurgegee word. ‘n Organisasie het dus ʼn meganisme nodig om die sistemiese omgewing mee te evalueer en sodoende prosesse te identifiseer wat belemmer is of wat belemmering kan veroorsaak. Die hoofdoel van hierdie navorsingstudie was om so ʼn meganisme te ontwikkel. Hierdie meganisme het na vore gekom in ʼn raamwerk wat tydens ondersoeke gebruik kan word om belemmering te identifiseer. Die raamwerk is ontwikkel deur hoofsaaklik drie dissiplines in gedagte te hou: Sistemiese Benadering, Prestasie-beoordeling en die Begrip van verskafferwaarde. Die raamwerk is aan die hand van drie gevallestudies getoets en in al drie gevalle het die raamwerk die verwagte resultate opgelewer. Die gevolgtrekking is dus gemaak dat organisasies wel die raamwerk kan toegepas kan om die sistemiese omgewing te evalueer en sodoende die belemmering van prosesse op mikrovlak uit te wys.

Повний текст джерелаENGLISH ABSTRACT: Additive Manufacturing (AM) refers to the technologies that use Computer Aided Design (CAD) data to produce plastic, metal, ceramic, paper, wax or composite materials parts. Their ability to join thin layers of liquid, powder or sheet materials together permits the production of parts, which are difficult or even impossible to produce, using any other manufacturing method. Even though these technologies are still developing, they are considered a major breakthrough in industry. One of the main problems that is facing the improvement and the spread of AM technologies, and its benefits worldwide, is the lack of knowledge about them. Still a lot of countries, educational and industrial organizations do not even know about AM technologies. This lack of knowledge of such technologies is keeping their cost artificially high, which is limiting the access to more AM advanced technologies and materials. It also makes it difficult to market the technologies and those who do not use AM technologies yet become unable to compete against those who do. The numbers of AM systems are continually growing, their capabilities and applications are improving and their cost is decreasing. Today there are more than 40 companies that produce over 100 different systems in Canada, China, France, Germany, Israel, Italy, Japan, South Korea, Sweden and the United States. These systems vary in their strengths, defects, applications, functions and limitations. This growth has led to an increase in current and potential users of AM from both the manufacturing and educational sectors. These users are however facing increasing complex problems when it comes to selecting the most appropriate commercial system(s) to suit their needs. The aim of this study is to develop an AM system selection program. The program will serve both as an educational tool and a decision making support tool to assist any potential purchasers in both the educational and industrial sectors. The AM system selection program is divided into two sections: the learning section and the selecting section. The learning section introduces the AM technologies by imparting knowledge to the new users; moreover, it inspires them to start using these technologies to get their benefits. Having a background in AM technologies enables the new users to make educated decisions and to discuss technical issues about the systems with the providers. The selecting section offers a decision making support tool to help the users to decide which system best suits their needs. This study can contribute to the promotion of AM technologies and their benefits worldwide, especially for the countries and organizations that have not yet used such technologies.
AFRIKAANSE OPSOMMING: Toevoegende vervaardiging verwys na al die tegnologie wat rekenaargesteunde ontwerp data gebruik om plastiek, metaal, keramiek, papier, saamgestelde materiale en waks parte te vervaardig. Die vermoë van die tegnologie om dun lae vloeistof, poeier of plaatmateriaal op mekaar te verbind laat die vervaardiging van parte wat moeilik of selfs onmoontlik is, deur die gebruik van ander vervaardigingsmetodes. Alhoewel hierdie tegnologieë nog in ‘n ontwikkelingsfase is, word dit as ‘n reuse deurbraak vir die bedryf beskou. Die verbetering, verspreiding en voordele van die tegnologie word hoofsaaklik belemmer deur ‘n tekort aan inligting daaroor. Baie lande, akademiese en industrieële organisasies is nog nie eens bewus dat sulke tegnologieë bestaan nie. Die tekort aan inligting veroorsaak dat kostes hoog bly en verhoed die vinnige uitbreiding van nog meer gevorderde tegnologieë en materiale. Verder bemoeilik dit ook die bemarking van die tegnologieë. Die aantal toevoegende vervaardigingsmasjiene groei jaarliks met beter vermoëns, laer kostes en ‘n groter verskeidenheid van toepassings. Tans is daar meer as 40 vervaardigers wat meer as 100 verskillende masjiene vervaardig in Kanada, China, Frankryk, Duitsland, Israel, Italië, Japan, Suid-Korea, Swede en Amerika. Al die masjiene verskil ten opsigte van hul funksies, beperkings en ook ten opsigte van sterkte, materiale en toepassings van parte. Die groei het gelei tot ‘n toename in gebruik van die tegnologie deur huidige en potensiële nuwe gebruikers van beide die vervaardigings en akademiese sektore. Die keuse van ‘n geskikte sisteem wat aan al ‘n gebruiker se vereistes voldoen, raak elke dag meer kompleks. Die doel van hierdie studie is die ontwikkeling van ‘n seleksie program vir toevoegende vervaardigingmasjiene. Die program sal dien as ‘n opleidingshulpmiddel en as ‘n basis vir masjienseleksie deur potensiële kopers. Die program bestaan uit twee dele: die opleidingsgedeelte en die selekteringsgedeelte. Die opleidingsgedeelte beskryf die verskeie toevoegende prosesse en motiveer gebruikers om die tegnologie aan te skaf weens die voordele. ‘n Agtergrond oor die verskeie tegnologieë stel die gebruiker in staat om ingeligte besluite te neem en tegniese vrae te kan stel aan verskaffers. Die selekteringsdeel het ‘n besluitnemingstruktuur wat help om die regte masjien te kies ten opsigte van verlangde vereistes. Hierdie studie kan help met die bevordering van toevoegende tegnologieë en hul voordele, veral vir lande en organisasies wat nog nooit voorheen sulke tegnologieë gebruik het nie.

Thesis, Linköping University, Department of Science and Technology, 2006. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-6551.
Повний текст джерелаWhen implementing an Enterprise Resource Planning (ERP) system, the system has to be adapted to the organisation. But just as important, the business processes of the organisation have to be reengineered in order to take full advantage of the ERP system. Noblessa Sverige AB, which is a sales company to the German kitchen producer Nobilia, has been growing remarkably since the start 2001 and has begun discussing an ERP system purchase. The order process of today has reached the limit of its capacity and something has to be done in order to meet the increasing sales volume.
The purpose of this master’s thesis is to analyse and reengineer the order process as a preparation for an ERP system implementation. The outcome of this thesis is a suggestion of a process model of the order process, which also can be used as a foundation for a requirements specification for the ERP system purchase. In order to take advantage of the benefits of the existing order process, the reengineering starts with mapping the current process.
Noblessa Sverige AB is a company that is growing and changing from one day to another. Changes have arisen during the writing of this thesis which has made the work even more interesting and challenging. The most important change is the opening of a central warehouse in Norrköping, which has been taken in consideration when we designed the new process model.
After mapping and achieving an understanding of the current order process, we found a few things that could be improved. Above all, there exist many manual tasks that can be automated with the ERP system. Furthermore, there are tasks that should be moved from one department or function to another because it is more suitable to perform them there. We also found that Noblessa Sverige AB should improve the integration and cooperation with its suppliers, especially Nobilia. Nobilia is the main owner and main supplier of Noblessa Sverige AB, the conditions for cooperation are therefore very good.

Повний текст джерелаSystems engineering rigor has been used successfully in the aerospace and defense industries where the development cycles tend to be rather long. However, the practice of using a traditional waterfall, spiral or V-model systems engineering life cycle framework, in other industries brings into question their appropriateness when considering the relative speed of new product development in industrial manufacturing. The purpose of this research is to investigate the applicability of incorporating systems engineering principles in the industrial sector to determine whether there is a statistical association with the overall growth of diversified industrial firms. This research focuses on investigating three systems engineering life cycle approaches: incremental & iterative methods, lean enablers for systems engineering and agile systems engineering; using a semi-structured interviewing approach with subject matter experts from the Fortune 500 diversified industrial sector. The research reveals that there are weak statistical associations between the use of the incremental & iterative and lean systems engineering life cycle approaches when considering the financial growth of the diversified industrial sector. However, the research reveals that there is a strong statistical association between the financial growth of companies in the diversified industrial sector and the use of the agile systems engineering life cycle approach as well as other unique life cycle tools.

Повний текст джерелаENGLISH ABSTRACT: Artificial intelligence has provided several techniques with applications in manufacturing. Knowledge based systems, neural networks, case based reasoning, genetic algorithms and fuzzy logic have been successfully employed in manufacturing. This thesis will provide the reader with an introduction and an understanding of each of these techniques (Chapter 2 & 3). The intelligent manufacturing process can be a complex one and can be decomposed into several components: intelligent design, intelligent process planning, intelligent quality management, intelligent maintenance and diagnosis, intelligent scheduling and intelligent control. This thesis will focus on how each of the artificial intelligence techniques can be applied to each of the manufacturing process fields. Chapter 5 Chapter 6 Chapter 7 Knowledge based systems Neural networks Fuzzy logic Case based reasoning Genetic algorithms Chapter 8 Chapter 9 Chapter 10 Manufacturing intelligence can be approached from two main directions: theoretical research and practical application. Most of the concepts, methods and techniques discussed in this thesis are approached from a theoretical research point of view. This thesis is also aimed at providing the reader with a broader picture of manufacturing intelligence and how to apply the intelligent techniques, in theory. Specific attention will be given to intelligent scheduling as an application (Chapter 11). The application will demonstrate how case based reasoning can be applied in intelligent scheduling within a small manufacturing plant.

"Customization Through Standardization : a study on Atlas Copco Tools & Assembly Systems’ market offer of fixtured tools to the motor vehicle industry." Thesis, Linköping University, Department of Management and Economics, 2004. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-6846.
Повний текст джерелаAtlas Copco Tools & Assembly Systems (ACTA) is world leader in industrial tools and assembly systems for safety-critical joints. One of the products the company sells is fixtured nutrunners, mainly to the motor vehicle industry. The margins on these highly customized products have been decreasing – much depending on changes in the purchasing behavior of the automotive industry.
Traditionally, the marketing of the fixtured nutrunners has been concentrated to the parts of the product instead of the final product. Today, there is a belief within the organization that many of the sold customized products could be replaced by more standardized applications. There is also a wish to turn the focus of the market offer from the parts towards the final application. These beliefs and wishes resulted in this thesis, with the purpose to propose a new market offer to increase profitability and give more customer benefits.
To reach this purpose we started out with theoretical studies of several different areas. Among those was mass customization, a strategy that combines the benefits of mass production with those of customization. We also performed a prestudy at the headquarters of ACTA in Sickla and visited major customers in Sweden. Using our collected knowledge from the theoretical studies and the prestudy, we conducted an in-depth case study by interviewing customers and people working at ACTA, both in Sweden and in the USA, in order to analyze today’s situation. In the analysis, we found several problems with today’s offer. For instance, we found that similar products are solved with unique solutions, which has lead to poor cost control and has made it difficult for ACTA to assure the quality of the ordered products. A further problem is the poor sales support and the lack of traceability of sold systems, which reduces sales and leads to unnecessary special solutions. A problem linked to that is the difficulties in getting accurate and sufficient information from the customer, which leads to extra errors and a lot of extra work.
To solve these problems, we recommend ACTA to implement a mass customization strategy. Of course, not all of ACTA’s products can be mass customized, but to a large extent it should be possible. To implement a mass customization strategy, we argue that ACTA should take three measures, namely design standard products, modularize the products, and implement a computerized configuration tool. We also suggest that the implementation of the new market offer should be done stepwise. With the proposed new market offer, we believe that ACTA can increase profitability in the area of fixtured nutrunners without losing the flexibility of the products.

Повний текст джерелаBakgrund: Att erhålla förståelse och observerbarhet av mjukvarusystem är en vital och nödvändig aktivitet, speciellt för testning och underhåll. Samtidigt så är dessa uppgifter både komplexa och tidskrävande för ingenjörer. Mikroservicearkitekturen som utnyttjas för att bygga molnintegrerade lösningar introducerar en hög grad av komplexitet. Fortsättningsvis, att kodifiera och distribuera teknisk kunskap har visats vara kritiskt för organisationers konkurrenskraft och finansiella resultat. Att göra det framgångsrik har dock flertal utmaningar och när flera mjukvarubolag under senare tid övergått till att arbeta virtuellt samt skiftat till DevOps har flertalet nya potentiella utmaningar uppdagats. Syfte: Målet med denna studie är att utforska hur systemförståelse av mjukvarusystem baserade på en mikroservicearkitektur kan förbättras utifrån prestandamätningar med hjälp av undersökande dataanalysmetoder. För att ytterligare utöka det praktiska affärsvärdet så avser avhandlingen även att undersöka effekterna som övergången till virtuellt arbete och DevOps har haft på denintern kunskapsspridning inom mjukvarubolag. Metod: En fallstudie utförs på Ericsson AB med prestandadata som genererats under testkörningar av ett system som kör på Kubernetes. Data extraherad med Prometheus och prestationsbeteendet utav fyra interagerande ”pods” utforskas genom korrelationsanalys och visualiseringsverktyg. För att undersöka effekterna från virtuellt arbete samt DevOps har på intraorganisatorisk kunskapsdelning av teknisk kunskap så utförs semi-strukturerade intervjuer som sedan korsanalyseras med litteratur. Resultat: Överlag så uppvisas hög korrelation mellan prestandamätvärden samtidigt som tydliga avvikelser observerades mellan testfall. Utöver detta så generades propositioner angående prestationsbeteendet samtidigt som potentiella kandidater för prediktiv modellering framhävs. Fyra nya potentiella determinanter identifieras för valet av aktiviteter samt överföringsmekanism, nämligen tillgänglighet, dynamik, etablerade processer, och effektivitet. Övergången till virtuellt arbete uppvisade främst fem positiva faktorer och tre negativa. Effekterna utav DevOps var särskilt kopplade till frekvensen av delning samt potential för automation. Slutsatser: Våra resultat tyder på att korrelationsanalys i kombination med visualiseringsverktyg kan användas för att skapa systemförståelse av molnbaserade system. Samtidigt som metoden visar potential för att analysera individuella tjänster och generera hypoteser så påvisar metoden i vår studie vissa nackdelar vilket tas upp i diskussionen. Resultatet tyder dessutom på att prestandadata kan vara en rik informationskälla för kunskapsskapande och bör vara av intresse för ytterligare studier.Resultaten av den kvalitativa undersökning indikerar att kunskapshantering inte bara är ett viktigt element ur akademins perspektiv men även något som omsorgsfullt praktiseras av industrin. Resultatet angående övergången till virtuellt arbete samt DevOps antyder på att båda har inflytande på hur kunskapsspridning bedrivs, både var för sig och i kombination. Samtidigt pekar våra undersökningsresultat på att övergången till att arbeta virtuellt potentiellt har påverkat kunskapshantering i betydligt större utsträckning än DevOps. Intervjuerna uppvisade både positiva och negativa aspekter utav den virtuella påverkan samtidigt som de positiva effekter som uppmättes av DevOps uppföljdes av omfattande utmaningar.

Повний текст джерелаIn this thesis was a model developed, in order to improve deficiencies in existing literature regarding the layout problem and to give companies a comprehensible user-friendly procedure on how to design competitive production processes, plant layouts and material handling systems. The model consists of six phases that can be used sequentially in order to design, evaluate, implement and maintain effective plant layouts and material handling systems. The model can also be used to examine and optimize processes. The first four phases of the model were tested successfully in a case study at Holtab AB, a medium sized manufacturing company in Tingsryd.

Повний текст джерелаThis thesis examines innovation and design processes in small established companies. There is a great interest in this area yet paradoxically the area is under-researched, since most innovation research is done on large companies. The research questions are: How do small established companies carry out their innovation and design processes? and How does the context and novelty of the process and product affect the same processes?
The thesis is built on three research papers that used the research method of multiple case studies of different small established companies. The innovation and design processes found were highly context dependent and were facilitated by committed resources, a creative climate, vision, low family involvement, delegated power and authority, and linkages to external actors such as customers and users. Both experimental cyclical and linear structured design processes were found. The choice of structure is explained by the relative product and process novelty experienced by those developing the product innovation. Linear design processes worked within a low relative novelty situation and cyclical design processes worked no matter the relative novelty. The innovation and design processes found were informal, with a low usage of formal systematic design methods, except in the case of design processes for software. The use of formal systematic methods in small companies seems not always to be efficient, because many of the problems the methods are designed to solve are not present. Customers and users were found to play a large and important role in the innovation and design processes found and gave continuous feedback during the design processes. Innovation processes were found to be intertwined, yielding synergy effects, but it was common that resources were taken from the innovation processes for acute problems that threatened the cash flow. In sum, small established companies have the natural prerequisites to take advantage of lead-user inventions and cyclical design processes. Scarce resources were found to be the main factor hindering innovation, but the examined companies practiced several approaches to increase their resources or use existing scarce resources more efficiently in their innovation and design processes. Examples of these approaches include adopting lead-user inventions and reducing formality in the innovation and design processes.

Повний текст джерелаDagens industriella marknader är i förändring med nya teknologier som omstörtar hur organisationer fungerar. Denna nya våg av teknik och fokusering mot hållbarhet medför ett skifte i kompetenser som behövs inom organisationer för att behålla sin konkurrensfördel. Antagandet av sådana tekniska innovationer utan att orsaka förseningar kräver ett brett spektrum av kompetenser bland anställda inomindustriella organisationer. Ett sätt att uppnå detta är att ha mångfald inom ledningsgrupper som speglar ett brett spektrum av kompetenser och färdigheter. Emellertid uppstår många utmaningar för att uppnå detta på grund av könsmärkta kulturer som finns i organisationer som påverkar utvärderings och befordringsprocesser. Syftet med denna rapport är därför att undersöka hur utvärderings- och befordringsprocesser i industriella organisationer kan bidra till återskapande och förändring av manlig dominans i organisationer, särskilt på ledningsnivåer. Syftet med denna rapport är att att utforska olika föreställningar om kompetens och utvärderings- ochbefordringsprocesser för att diskutera hur könsbalans inom organisationer kan uppnås. Rapportenutgår från forskning om organisationsförändring, könsmärkta ideal, homosocialitet, föreställningar om kompetens och metoder för utvärdera medarbetare och bygger på en fältstudie i ett mansdominerat svenskt industriföretag. Analysen fokuserar hur utvärderings- och befordringsprocesser kan bidra tillatt mansdominans återskapas och möjliga sätt att förhindra att det händer. De föreslagna rekommendationerna utgår från forskning om jämställdhetsarbete.
