Introduction The number of the people who needs dialysis escalates rapidly year each. The rising cost of dialysis is relative. Because Bureau National Health Insurance endures the co-payment of hemodialysis, patients have freedom of choice. Two critical factors that influence patient¡¦s decision in medical care are access and quality. Facing pressure from competition, many hemodialysis service providers believe that high quality service will retain patients to return as well as maintain a healthy physician-patient relationship. Therefore, they apply many quality management tools, which also include service pathways. There are few investigations that discuss service pathways. Thus, this research constructs a model to analyze the effect of service pathways in hemodialysis service providers. Method From Nov. 1, 2003 to Dec. 31, 2004, the researcher interviewed hemodialysis nurses to develop flow chart, customer encounter, and check list for hemodialysis. We also collected the check list records of the hemodialysis patients to examine the effect. Conclusion First, the construction of total service pathways comprised three critical interlocking phases: flow chart, customer encounter, and check list. After that we shall evaluate and correct them continuously. Secondly, the researcher found that most patients are routine members, and come from long-term care center and respiratory care ward (RCW). Thirdly, the indicators influencing hemodialysis results and error incidents were steady. Finally, in the value-added services dimensions, the indicators of nurses¡¦ performance on greeting and asking patients if they want to have a meal were significant, but the indicators of telephone and inpatient interview were unfavorable.

This thesis is focused on identification and evaluation of errors during pneumatic valve assembly. Theoretical part describes tools used: quality gate, flow chart, Pareto diagram and FMEA analysis. Within practical part the current assembly process is analyzed with current errors and besides evaluation, the improvement priorities and ways to accomplish these improvements in an actual company are defined. If the company chooses to take the opportunity to implement these improvements, thesis also monitors the results and reaction to the change of the analyzed process to a certain point.

Keolis conducts public transport on behalf of municipalities around the country. Through locally adapted and sustainable city traffic, Keolis creates value for travelers, society and owners. The company has been wholly owned by the international public transport group Keolis since the autumn of 2010. Keolis is located in Jönköping County, Örebro County, Stockholm County, Västra Götaland, Värmland, Östergötland and Dalarna. The company's working method focuses on putting the traveler's needs in focus, which is to offer the solution that is best for travelers and the environment, regardless of the type of traffic. One step in the company's journey was in 2017 a decision to centralize the personnel planning department to be able to increase steering towards set goals and saving resources. Process and flow activity are two interwoven pillars for successful efficiency improvement work. It is in the process that flow activity arises. In order to streamline flow activity, we need to understand the process The starting point for the project is a preliminary study conducted at the company earlier 2019. The preliminary study analyzed the flow process "preparing the traffic day" within the personnel planning department for the Stockholm area and identified improvement areas ahead of upcoming in-depth analysis that takes place in this work. An action plan for identifying and prioritizing improvement areas at the department is presented. The conclusion states the importance of introducing methodological working methods to enable continuous improvements. Based on the identified areas of improvement, the study is designed to answer the question of what improvement should be prioritize and in what order should the organization implement improvements. The implementation would accrue in working methods and approach to gradually streamline the department after centralization Subsequently, an action plan for identifying and prioritizing improvement areas at the department is presented. The conclusion states the importance of introducing methodological working methods to be able to work with continuous improvements. In the near future, leveling out workflow is necessary for stabilizing the process and providing the opportunity to reach the system limit. There are good chances to further develop the department by changing perspectives on the distribution and introducing new working flows. Improvements to these areas will lead to the gradual fulfillment of the initial goal of centralization in the form of a standard approach and increased productivity and profitability. / Keolis bedriver kollektivtrafik på uppdrag av kommuner runt om i landet. Genom lokalt anpassad och hållbar stadstrafik skapar Keolis värde för resenärerna, samhället och ägarna. Företaget ägs sedan hösten 2010 till 100 procent av den internationella kollektivtrafikskoncernen Keolis. Keolis finns i Jönköpings län, Örebro län, Stockholms län, Västra Götaland, Värmland, Östergötland och Dalarna.  Företagets arbetssätt fokuserar på att sätta resenärens behov i fokus, vilket är att erbjuda den lösning som är bäst för resenärer och miljön, oavsett trafikslag. Ett steg i företagets resa blev under 2017 ett beslut om att centralisera avdelningen personalplanerare för att kunna öka styrningen mot uppsatta mål och uppnå besparing av resurser. Process och flödesaktivitet är två sammanflätade grundpelare för ett lyckat effektiviseringsarbete. Det är i processen som flödesaktivitet uppstår; för att effektivisera flödesaktivitet behöver det finnas förståelse för processen.  Hos Keolis Sverige AB analyseras flödesprocessen ”förbereda trafikdagen” inom avdelningen personalplanering för Stockholmsområdet. Processen ska handla om planering och bemanning av personal för en trafikdag. Målet med denna uppsats har varit att kartlägga dagens flödesschema, analysera problemområden samt ta fram förbättringsförslag. En analys av flödesschema för processen har genomförts, där medarbetare från avdelningen personalplanerare samt trafikområden har varit involverade. Detta för att fånga upp möjliga förbättringar samt skapa en delaktighet inför framtida förändringar. Examensarbetet har avgränsats till att endast analysera Stockholmsområdet. Baserat på de identifierade förbättringsområdena har studien utformats för att besvara frågeställningen om vad organisationen bör prioritera och i vilken ordning organisationen bör genomföra förbättringar i arbetssätt och metoder för att gradvis effektivisera avdelningen efter centralisering. Utgångspunkten för examensarbetet är en förstudie utförd hos företaget tidigare samma år. Förstudien analyserade flödesprocessen ”förbereda trafikdagen” inom avdelningen personalplanering för Stockholmsområdet och identifierade förbättringsområden inför kommande fördjupad analys, vilken har skett i detta arbete.  En handlingsplan för att identifiera och prioritera förbättringsområden hos avdelningen presenteras. Slutsatsen visar vikten av att införa metodiska arbetssätt för att kunna jobba med ständiga förbättringar. I närtid är att jämna ut arbetsflöde nödvändigt för att stabilisera processen och ge möjlighet till att uppnå systemgränsen. Det finns goda chanser till att utveckla avdelningen ytterligare genom att ändra perspektiv på fördelningen och införa nya arbetssätt och fördelningar bland personalplanerare. Förbättringar av dessa områden kommer att leda till gradvis uppfyllelse av det ursprungliga målet för centraliseringen i form av ett enhetligt arbetssätt samt ökad produktivitet och lönsamhet.

Small size of electronic product with high layout density is the future trend in today¡¦s high speed digital circuit design. A circuit designer is obliged to optimize the best solution of circuit layout in a limited area in order to both keep a good signal integrity¡]SI¡^, and save the layout space. Meander delay line is one of the challenging topic in high-speed circuit. In this dissertation, a effective method is provided to design a meander delay line, and FDTD and HFSS are matched up to predict the behavior and the character of the meander delay line; the differential meander delay line is compared with the single meander delay line, and the behavior and phenomena of the differential meander delay line are discussed. To reduce couple power, the differential meander line of design would be a new thinking. The most important point in this thesis, the complete flows of designing single meander lines and differential meander lines are provided, and designer could follow the steps of the proposed method to design a perfect and practical meander line with both keeping good SI and using least layout space. The effect of the design parameters of the meander line on the signal quality both in time-domain and frequency-domain is theoretically and experimentally investigated. FDTD method and the commercial tool HFSS are employed for the numerical study in this work.
