This thesis considers the disk scheduling problem. The problem is investigated in two types of settings: offline and online. We first adopt the traveling salesman problem with time windows in the scheduling literature for solving the offline problem. Then we develop a decision epoch scheme in which offline problems are iteratively used in solving the online problem. We perform an experimental study for our approach and two well-known disk scheduling algorithms, and compare them according to several performance criteria.

This master thesis aims on the means of how Czech children and youth spend their leisure time. Great focus is also given to attractivness of the activities. The problem addressed by the author in this thesis is the increasing percentage of the prevalence of childhood obesity in the Czech Republic and it's connection with the increase in technological dependency of children and youth. The main goal of this thesis is to describe whether there is a connection between the aforementioned phenomena. Another goal focuses on ways of spending free time and base on author's own research adresses the attractivness of the activities, i.e. which leisure time activities are more and less attractive for children and youth, what children enjoy in their free time and how they really spend it. For these purposes, the author sets up hypotheses in the thesis, the validity of which is addressed by the research questions in order to achieve the main objectives of the work. The author defines the basic concepts for better orientation in the text which is divided into analytical and empirical parts. The author even introduces two new concepts: the online world and the offline world. In the final part of the thesis the author suggests the possibility of connecting the online world and the offline world for further...

In recent years, omnichannel strategies have increased, which has changed consumer purchasing decisions process. With this, the purchase decision has changed the way consumers approach to make purchase decisions, which leads to the purchase process being reshaped. The approach has become more complex with other aspects to consider in current consumer purchasing decisions. Therefore, the purpose of this thesis has been to investigate how omnichannel strategies, which integrate online and offline shopping platforms, shape consumers' purchase decisions in Sweden's fast fashion industry for generation Z. The empirical results were obtained using a qualitative case study of 25 participants from Sweden through semi-structured interviews. The findings were then analysed and discussed with the presented literature to identify how consumers' purchase decisions in Sweden's fast fashion industry for generation Z have been shaped by omnichannel strategies, integrating online and offline shopping platforms. The conclusion of this thesis shows that it is complex to assume how omnichannel strategies, integrated by online and offline shopping platforms, shape generation Z purchase decisions in Sweden's fast fashion industry because the impact of these strategies is unique to each individual's shopping journey. This means that every purchase decision is personally individual and varies depending on the consumer's unique approach to purchasing in the complex and interconnected world of integrated omnichannel strategies, where the online and offline channels are seamlessly connected to provide a unified shopping experience.

O2O 是一個嶄新的商業模式，透過網路上的服務提供導引線上消費者到線下店面進行消費或是取用實體服務。在近年，O2O迅速成為眾企業討論的話題。除了知名零售和電子商務企業，O2O商業模式以在各行各業中逐漸發展，舉例來說，知名零售業的Walmart和Target; 服飾業的Uniqlo和GAP; 配件-眼鏡的Warby Parker和餐飲業麥當勞和Instacart。業界充滿林林種種的實際個案，但學術上卻缺乏完整的研究來說明O2O的現況，我們不了解O2O的定義和範圍，甚至對於企業來說，到底該如何成功地實現O2O的精華。此篇研究的目的是希望能提供企業更具體了解O2O的概觀，並可以檢視在規劃一個O2O專案的發展需要有哪些關鍵成功因素。 基於之前少數的文獻和大量從網路、報章雜誌所蒐集的業界個案，我們的研究透過這些資料蒐集分為兩階段研究。第一階段，根據蒐集的資料，我們建立五種型態的O2O 商業模式 –(1) Commerce O2O; (2) Try-on O2O; (3) Promotional O2O; (4) Experience O2O; and (5) Crowdsourcing O2O。我們專注在promotional O2O的五家在台灣企業的個案研究。第二階段，根據文獻我們先定義出可能的關鍵成功因素列表，再舉辦深入的企業訪談，透過訪談的方式來驗證並修改原本的關鍵成功因素列表，為3個分類-(1)4個技術關鍵成功因素: 系統操作友善, User Interface 設計, 精確的定位, 穩定的IT系統承載的能力;(2)5個管理關鍵成功因素-管理者支持, 客戶關係管理, 使用者參與方案設計, 專案執行的高貫徹度, 專案的監控管理追蹤;(3)4個組織關鍵成功因素-完整的人員訓練, 線上線下的流程無縫整合, 不斷創新與思考方向, 明確的專案目標。最後，我們希望這篇研究可以幫助企業更了解O2O商業模式，並且幫助他們有效的發展O2O專案。 / Online-to-Offline (O2O), a brand-new business model that drives online visitors to purchase in-store by offering services online, has received a great deal of attention. In addition to well-known retailers and ecommerce businesses, the O2O business model has been adopted by companies across a variety of industries, such as Target and Macy's in retailing, GAP and Uniqlo in apparel, Warby Parker in accessories and McDonald’s and Instacart in food. However, less attention has been paid in the literature to the clear definition and scope of both online and offline businesses in the O2O business model, and there is limited understanding of how to build a successful O2O project. The objective of this study is to organize comprehensive information for the O2O business model and to examine the critical success factors (CSFs) for building O2O business models. Based on the literature and case studies of the O2O business model, this study builds a framework for data collection and is conducted in two stages. First, we build a preliminary finding regarding the five major types of O2O business models—(1) Commerce O2O; (2) Try-on O2O; (3) Promotional O2O; (4) Experience O2O; and (5) Crowdsourcing O2O—based on the literature and more than 50 practical cases and select five promotional O2O companies in Taiwan as our focus. Second, we conduct an in-depth case study on selected cases related to possible CSFs for successful O2O implementation. The critical success factors (CSFs) for building O2O business models are–(1) Four factors of technological dimension- User Interface design, Ease of use application, Accurately located function and IT load balancing capability; (2) Five factors of management dimension- Management support, Good CRM system, Strategic execution capability, Actively involve end users in solution design and Measure, monitor, and track; (3) Four factors of organization dimension- Complete staff training, Seamless the process of online and offline channels, Reinvent the company's future and Establish a clear project goal. The research results not only provide a complete O2O overview but also verify and enhance the list of CSFs for building O2O business models. It is hoped that we can gain a better understanding of the O2O business model from these cases and thus help companies develop effective plans for building O2O projects.

繼網路創業後，近年來可以看到以行動應用創業的案例越來越多，而之中又以整合虛實通路的O2O (Online to Offline，線上至線下的通路模式)模式更為熱門。過去由於虛擬通路的盛行，造就了電子商務的快速發展，也因而使得消費資訊傳遞得更加快速。在這樣的情況下，企業的策略與經營模式也不斷地調整，電子商務方面則產生了很大的變化，原本只著重於經營虛擬通路的企業，開始反向經營實體通路，而原本只經營實體通路的企業，則開始經營起虛擬通路。 本論文研究主要的目的在於探討台灣新創公司如何經營O2O的模式，本研究以核心資源、營運範疇、事業網路等三構面，探討三家新創公司（食我餐飲顧問公司、百迪爾資訊公司、呼叫師傅公司）O2O方面的經營策略，並藉由第四構面-價值創造，探究該等公司在O2O服務上所創造的價值。 本研究所得到的主要結論包括：(1)新創公司在O2O的初期經營上，會著重於需求端。(2)新創公司在經營O2O的業務推廣上，會尋求外部資源的協助。(3)新創公司在經營O2O的服務品質控管上，會透過廠商篩選機制的建立以及與廠商的合約來加以強化。(4)新創公司在O2O的經營上，會透過在地資訊的即時提供來提高使用者採用O2O平台的意願。本文最後並提出實務上的意涵與後續研究的建議。 / Since the trend of running businesses on the Internet started to foster, we could see that there are more and more cases taking portable devices as the core of their business. Besides, the Online to Offline (O2O) business model of using the clicks-and-mortar channel might be one of the most popular choices. In the past, due to the prevailing of virtual channel, it did make e-commerce to be in vogue, and also help consuming information to transact more rapidly. In this kind of situations, the business strategies and business models of enterprises also kept on making adjustments to follow the flow. As for e-commerce, it did resulted in huge changes. For those enterprises who used to concentrate on virtual channels, they started the business of physical channels; those enterprises who only aiming at running physical channels started to explore the area of virtual channels. The main purpose of the study is to discuss about how those Taiwanese start-up companies operate O2O business. Moreover, the study takes core resources, operating area and business networks to view the O2O business strategies of three start-up companies. Also, by using value creation, the study wants to understand the value created by the O2O business of those companies. After the research of the issues above, the study came up with four main conclusions: 1. Start-up companies would concentrate on the demand side in the beginning of their business. 2. Start-up companies would seek for the help of outer resources when they were promoting their business. 3. In the aspect of controlling the quality of their services, start-up companies would choose to build the filtering system of target companies and signing contracts. 4. In running O2O business, start-up companies would offer local information immediately to raise consumers’ will of using their O2O platform. With those four main point provided by the study, it also brings up the meaning the practical meaning of the study and suggestions of following researches. Keywords: Start-up Company, O2O (Online to Offline), Business Strategy, Value Creation

Studien diskuterar hur sociala interaktioner och identiteter förändras i en digital värld. Syftet är att sätta online och offline i kontext till varandra för att kunna analysera användares beteende och identiteter. Följande tre forskningsfrågor har valts ut för att besvara studiens syfte genom en kvalitativ intervjustudie, (1) Hur beskriver respondenterna att deras identitet har influerats när en betydande del av deras sociala interaktion sker online? (2) På vilket sätt försöker respondenterna återskapa sociala institutioner som vanligtvis existerar i face-to-face-interaktioner i det digitala landskapet? (3) Vilken betydelse menar respondenterna att sociala medier har för deras relationsskapande? Vi har använt oss av följande teorier: social identitetsteori, social penetrationsteori och begreppet affordance för att analysera materialet. Goffmans främre och bakre rum har en framträdande och betydande roll genom studien. Resultatet av vår undersökning är att online- och offlinekontexterna kompletterar varandra och behöver varandra för att vara fullständiga. Sociala institutioner offline är också framträdande online. Samma sak gäller normer, att gå utanför ramar kan skapa utanförskap även i en onlinekontext. Sammanfattningsvis är sociala interaktioner och identiteter två fenomen som ständigt är i utveckling. Den här studien bygger på ett litet antal respondenter där resultatet inte kan svara för allmänheten, men vi hoppas att studien kan vara värdefull för vidare inomvetenskaplig forskning. Nyckelord: Sociala medier, identitet, sociala interaktioner, online- och offlinekontext, beteende, relationer.

Les normes de construction pour des bâtiments de plus en plus économes en énergie (BBC) nécessitent une attention particulière. Ces normes reposent sur l’amélioration des performances thermiques de l’enveloppe du bâtiment associé à un effet capacitif des murs augmentant la constante de temps du bâtiment. La prévision de la demande en énergie de bâtiments BBC est plutôt complexe. Ce travail aborde cette question par la mise en œuvre d’intelligence artificielle(IA). Deux approches de mise en œuvre ont été proposées : « all data » et « relevant data ». L’approche « all data » utilise la totalité de la base de données. L’approche « relevant data » consiste à extraire de la base de données un jeu de données représentant le mieux possible les prévisions météorologiques en incluant les phénomènes inertiels. Pour cette extraction, quatre modes de sélection ont été étudiés : le degré jour (HDD), une modification du degré jour (mHDD) et des techniques de reconnaissance de chemin : distance de Fréchet (FD) et déformation temporelle dynamique (DTW). Quatre techniques IA sont mises en œuvre : réseau de neurones (ANN), machine à support de vecteurs (SVM), arbre de décision (DT) et technique de forêt aléatoire (RF). Dans un premier temps, six bâtiments ont été numériquement simulés (de consommation entre 86 kWh/m².an à 25 kWh/m².an) : l’approche « relevant data » reposant sur le couple (DTW, SVM) donne les prévisions avec le moins d’erreur. L’approche « relevant data » (DTW, SVM) sur les mesures du bâtiment de l’Ecole des Mines de Nantes reste performante. / High-energy efficiency building standards (as Low energy building LEB) to improve building consumption have drawn significant attention. Building standards is basically focused on improving thermal performance of envelope and high heat capacity thus creating a higher thermal inertia. However, LEB concept introduces alarge time constant as well as large heat capacity resulting in a slower rate of heat transfer between interior of building and outdoor environment. Therefore, it is challenging to estimate and predict thermal energy demand for such LEBs. This work focuses on artificial intelligence (AI) models to predict energy consumptionof LEBs. We consider two kinds of AI modeling approaches: “all data” and “relevant data”. The “all data” uses all available data and “relevant data” uses a small representative day dataset and addresses the complexity of building non-linear dynamics by introducing past day climatic impacts behavior. This extraction is based on either simple physical understanding: Heating Degree Day (HDD), modified HDD or pattern recognition methods: Frechet Distance and Dynamic Time Warping (DTW). Four AI techniques have been considered: Artificial Neural Network (ANN), Support Vector Machine (SVM), Boosted Ensemble Decision Tree (BEDT) and Random forest (RF). In a first part, numerical simulations for six buildings (heat demand in the range [25 – 85 kWh/m².yr]) have been performed. The approach “relevant data” with (DTW, SVM) shows the best results. Real data of the building “Ecole des Mines de Nantes” proves the approach is still relevant.

This diploma thesis which is titled Communication of selected companies in online and offline environment (illustrated on enterprises České dráhy, RegioJet and Leo Express) aims to map the communication activities of the mentioned carriers on online and offline media platforms in the Czech environment. In the theoretical part is defined the basic terminology of analyzed issues, above all from the area of communication, media, marketing and partially also from the perspective of linguistics. The practical part besides the methodology includes a presentation of the analyzed companies, České dráhy, RegioJet and Leo Express, and also a descriptive analysis of their presentation or more precisely communication activities on various media types and platforms - for each of the mentioned companies separately. Furthermore, in the practical part there is a comparison of analyzed companies, based on the results of descriptive analysis and there is also a description of an additional quantitative analysis - a questionnaire survey, which was answered by a total of 808 respondents of all ages from all over the country - so in this case from the customer's point of view. At the end of the practical part, the results are summarized and evaluated, and besides, there are also from them following recommendations -...
