A case study of selecting suppliers in China

Guan, Xueying, Wang, Shenning January 2009 (has links)
Based on current competitive market, supply chain becomes to be more and more important to overall corporate strategy. Finding good suppliers makes much more senses for the companies nowadays as purchasing is one of the basis parts on the upstream of the supply chain. China has been very successful on turning itself into a production powerhouse in just two decades, so how to find and select the convenient suppliers in China is a very important and modern topic. The thesis has been starting with the introduction part, where the importance of outsourcing, Chinese current manufacturing capabilities and some other factors will be introduced. Besides, the purpose of this thesis is to study and analysis the criteria and processes are used by PCH International on the selection of suppliers in China. The authors try to understand how foreign companies find the right Chinese suppliers based on a case studying, which is PCH International, an Irish company. Within the theoretical framework part, the authors discussed the supplier selection criteria firstly, which are very important and necessary to evaluate suppliers’ performances. Then the thesis was provided with an insight into some common theoretical methods, which followed by the supplier selection processes. Total Cost of Ownership, Data Envelopment Analysis and Mathematical Programming are presented in basic term. The part in the theoretical review was informed about the structure of the supplier selection process, starting with the preparation step, followed by prequalification and evaluation steps and resulting in the final selection of the suppliers. In the methodology part, the approach for the research will be presented, it will be divided into four parts, which are choice of topic, choice of method, data collection, research’s validity and reliability. The empirical finding part consists of practical information which was provided by the case company mentioned above through questionnaires and interviews. The values of the evaluation criteria are depend on the respective goals. For data analysis, the theoretical evaluation models, on the other hand, are not used by this case. The company uses their own methods which are presented in the empirical part as well as in the analytical part of this thesis, the reasons will be describe carefully in this chapter. Finally, this thesis ends with a conclusion, which with the answer of the research question.

Partnerval i joint ventures på den svenska 3G-marknaden En studie av de svenska nätoperatörerna

Danielsson, Teodor, Edgren, Erik January 2002 (has links)
<p>Background: Traditionally defined boundaries and borders between organizations are at present being re-evaluated because of new and tougher demands. Today we can see a trend where these boundaries are being lowered or even eliminated when organizations choose to co-operate instead of compete. </p><p>Purpose: In order to create an understanding for the partner selection process in the newly founded joint ventures between the companies which are building the Swedish 3G Network, the determining factors are being studied. </p><p>Delimitation: The studies companies are co-operating as network operators but are at the same time competing as mobile operators. This relationship is in the literature described as co-opetition, which will not be investigated in this paper. </p><p>Realization: Taking our starting point in Geringer’s task- and partner-related approach, a simple model has been created for the task. Empirical data have been collected through interviews, and have been analyzed with this model. </p><p>Results: Essentially the same factors have been found determining for the companies which have committed themselves for co-operation. These factors do however tend to differ partly between the two joint ventures that have been founded. In the Europolitan Vodafone” Hi3G joint venture, compatibility between top management and culture&structure seem to be the motivating factors. From a Telia - Tele2-perspective, the mutual factors seem to be financing and compatibility between top management. An important criterion has in both joint venture constellations to the access to existing real capital and infrastructure as well as having existing customers.</p>

Magkänsla mot matematik : Kan mekanisk rekrytering förhindra diskriminering?

Gustafsson, Jennifer January 2015 (has links)
The aim of this study was to investigate if a mechanical recruitment process could be a useful tool for employers to avoid discrimination. National and international law protect jobseekers from discrimination during the recruiting process. Despite this individuals frequently report that they are treated unfairly when they apply for a job. In line with this research shows that some individuals do not have the same opportunities in the labour market as the rest of the population. This study focus on discrimination based on ethnicity, age, gender or disability. Today most of the hiring decisions are based on employers professional judgement. This constitute a potential risk for discrimination since the judgement can be influenced by prejudices and stereotypes. The research shows that employers tend to measure variables which are not relevant for individuals future job performance when they make decisions in selection processes. A mechanical approach for the recruitment can broadly correct for this since it is based on standardized procedures that eliminates human judgement. The data collection of candidates strictly relate to a defined job profile which only contains criterions that are of importance for the employment. Pre-specified algorithms are later on used for combining each candidates data into an overall assessment. This regulates that the same criteria is measured for all individuals. In order to analyse the material a legal dogmatic method has been combined with a legal sociology method.

Grynnor och farleder i karriärvalsprocessen : Unga med rörelsehinder och deras handlingsutrymme / Reefs and Fairways in the Career-Selection Process : Young adults with mobility impairments and their margins for maneuvers

Söderberg, Elisabet January 2014 (has links)
This thesis deals with the career choices of young adults (ages 18 through 40) with mobility impairments and the experiences they had throughout their career-selection process. The purpose of the study was: To find the inhibitory and furthering factors of the career choices of people with mobility impairments from their own perspective, with a special focus on how various factors affected the process over time. The method for collecting the results of this study was biographical interviews. The main theories of the study were Sense of Coherence, Self-efficacy, Learned Helplessness, Social Role Valorization and The Four Rooms of Change. The results show that mobility impairment affects career choices and that the effect is more often inhibitory than it is furthering. Structural factors, such as how the respondents are treated by other people, as well as rules and material barriers (stairs, mal-functioning elevators, etc.) are found to be more limiting than the body itself. Being over-protected is a main inhibitory factor which can contribute strongly to low self-efficacy and drainage of self-image for the respondents.  The goal of the respondents is to obtain independence and a job based on their own terms, and not a social care career. This goal was found to form a vital resistance resource versus adversity and obstacles. The respondents consider themselves to be overprotected by society (by parents, teachers, career counsellors, employment officers, etc.) in relation to their career choices, and they would like not to be. / <p>Forskningsfinansiärer: Torsten Söderbergs Stiftelse och Ragnar Söderbergs Stiftelse</p>

Kandidatupplevelse i rekryteringsprocessen vid ett stort svenskt industriföretag

Andersson, Josefine, Collén, Kristin January 2015 (has links)
Målet med rekrytering är att identifiera och attrahera potentiella arbets-sökanden utan att påverka dessa negativt. Tidigare forskning har visat att kandidatupplevelsen påverkas av huruvida den arbetssökande upplever rekryteringsprocessen som rättvis. Syftet med denna studie var att undersöka hur en rekryteringsprocess upplevs av arbetssökanden samt om kön, generationstillhörighet respektive arbetsgivarens attraktivitet har ett samband med kandidatupplevelse. Även skillnader utifrån ansökt yrkesområde, hur långt kandidaten tog sig, samt hur kandidaten fick det slutgiltiga beskedet undersöktes. Deltagare var 1261 arbetssökanden, varav 1009 var män, som under en sexmånadersperiod sökt arbete på ett stort svenskt industriföretag. Utifrån mätinstrumentet Selection Procedural Justice Scale (SPJS) utformades en webbenkät. Resultatet visade att det finns en skillnad i kandidatupplevelse utifrån kandidatens utfall i rekryteringsprocessen, mottagandet av slutgiltigt besked samt hur attraktiv arbetsgivaren anses vara. Rekryterare bör vara noga med att väsentlig återkoppling når varje kandidat. Undersökningen bidrog med nya insikter om kandidatupplevelse, främst utifrån individuella skillnader.

Certified Ejection Seat Weight Ranges and their Effects on Personnel Selection

Jones, Thomas C. 09 1900 (has links)
Human Systems Integration Capstone / Approved for public release; distribution is unlimited / Current ejection seat certified aircrew weight ranges (136 to 213 lbs.), such as for the F/A-18, prohibited over one third (38%) of women and (8%) of men from accessing the naval aviation strike pipeline (carrierbased aviation) between 2008 and 2013. This is deleterious to the Naval Aviation Enterprise to restrict access of otherwise qualified and talented applicants to the strike aviation pipeline due to an outdated anthropometric survey based specification. The acceptable level of risk that was utilized by the Naval Aviation Systems Command was overly conservative and needs to be updated to align with current operational risk management principles, actual ejection seat performance mishap data and the naval aviation anthropometric population. This research is a deep exploration of all aspects of this issue and makes recommendations that can be used by Commander of Naval Air Forces in establishing an operational weight limit for all ejection seat aircraft.

Preference and context-based BDI plan selection using machine learning : from models to code generation / Seleção de planos BDI baseada em contexto e preferências usando aprendizado de máquina : dos modelos à geração de código

Faccin, João Guilherme January 2016 (has links)
A tecnologia de agentes surge como uma solução que fornece flexibilidade e robustez para lidar com domínios dinâmicos e complexos. Tal flexibilidade pode ser alcançada através da adoção de abordagens já existentes baseadas em agentes, como a arquitetura BDI, que provê agentes com características mentais de crenças, desejos e intenções. Essa arquitetura é altamente personalizável, deixando lacunas a serem preenchidas de acordo com aplicações específicas. Uma dessas lacunas é o algoritmo de seleção de planos, responsável por selecionar um plano para ser executado pelo agente buscando atingir um objetivo, e tendo grande influência no desempenho geral do agente. Grande parte das abordagens existentes requerem considerável esforço para personalização e ajuste a fim de serem utilizadas em aplicações específicas. Nessa dissertação, propomos uma abordagem para seleção de planos apta a aprender quais planos possivelmente terão os melhores resultados, baseando-se no contexto atual e nas preferências do agente. Nossa abordagem é composta por um meta-modelo, que deve ser instanciado a fim de especificar metadados de planos, e uma técnica que usa tais metadados para aprender e predizer resultados da execução destes planos. Avaliamos nossa abordagem experimentalmente e os resultados indicam que ela é efetiva. Adicionalmente, fornecemos uma ferramenta para apoiar o processo de desenvolvimento de agentes de software baseados em nosso trabalho. Essa ferramenta permite que desenvolvedores modelem e gerem código-fonte para agentes BDI com capacidades de aprendizado. Um estudo com usuários foi realizado para avaliar os benefícios de um método de desenvolvimento baseado em agentes BDI auxiliado por ferramenta. Evidências sugerem que nossa ferramenta pode auxiliar desenvolvedores que não sejam especialistas ou que não estejam familiarizados com a tecnologia de agentes. / Agent technology arises as a solution that provides flexibility and robustness to deal with dynamic and complex domains. Such flexibility can be achieved by the adoption of existing agent-based approaches, such as the BDI architecture, which provides agents with the mental attitudes of beliefs, desires and intentions. This architecture is highly customisable, leaving gaps to be fulfilled in particular applications. One of these gaps is the plan selection algorithm that is responsible for selecting a plan to be executed by an agent to achieve a goal, having an important influence on the overall agent performance. Most existing approaches require considerable effort for customisation and adjustment to be used in particular applications. In this dissertation, we propose a plan selection approach that is able to learn plans that provide possibly best outcomes, based on current context and agent’s preferences. Our approach is composed of a meta-model, which must be instantiated to specify plan metadata, and a technique that uses such metadata to learn and predict plan outcomes. We evaluated our approach experimentally, and results indicate it is effective. Additionally, we provide a tool to support the development process of software agents based on our work. This tool allows developers to model and generate source code for BDI agents with learning capabilities. A user study was performed to assess the improvements of a tool-supported BDI-agent-based development method, and evidences suggest that our tool can help developers that are not experts or are unfamiliar with the agent technology.
