PROCESS OPTIMIZATION AND AUTOMATION IN E-COMMERCE BUSINESS OPERATION

Mister Sandman is an ecommerce start-up company located in the heart of Berlin, Germany. It is an online mattress & bedding company, selling products both on their own as well as 17 other marketplaces across Europe. I have successfully completed 6 months of my internship with the company. It was really an amazing experience here to work and learn. This journey has been very informative, interesting, and important on all scales. I was entrusted with various projects and tasks and actively worked on data collection, cleaning, manipulation, preprocessing, visualization, analysis, and automation of various tasks in the company's ecommerce platform and marketplaces. In the beginning, I was trained to understand the end to end working mechanism of day to day operations. My goals and areas of contribution were precisely put forward to me which empowered me with focus and clear vision. I then utilized my knowledge from the university and past experience of work at Amazon to support them in an efficient way. I made an analysis on Pricing, Rebate, Shipping, Ratings & Reviews, Inventories, Visibility, Orders & Sales and worked on to optimize and automate the process using various techniques of python skills. I also learnt and used other technical skills and languages to execute the tasks along with Python such as SQL, Macros, Tableau and Power BI tools depending on the requirements. I also make different reports for the orders & sales - weekly and monthly using various analysis and visualization tools and contributed to understand the development and improvement areas for the business to grow and continue serving our customers the best way.Mister Sandman is an ecommerce start-up company located in the heart of Berlin, Germany.

Bursting the broadband bubble

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Broadband has revolutionised the way the Internet is used and has become the critical enabling infrastructure of our modem and knowledge-based economy. Its widespread introduction has not only greatly enhanced the speed at which information online can be accessed, but also the range and sophistication of the content available. It is still penetrating the telecommunication market and is seen by some as the most significant evolutionary step since the emergence of the Internet. However in the rush to achieve market share, there is a risk that insufficient attention may be paid to quality issues, the central theme of this research. The research addresses the issues of broadband quality with a stated objective of assessing broadband quality by means of an integrated framework that encompasses factors beyond strict technical characteristics of broadband networks. Indeed, the concept of quality is a multi-facetted one, for which various perspectives can be distinguished. In this work, broadband quality as perceived by users, ISP and Government in the United Kingdom (UK) is looked at and a survey report is given and analysed. The aim of this doctoral research was to provide much needed empirical broadband quality framework that would guide the service provider as well as the UK government in the provision of quality broadband to its consumers. It will also stand as a benchmark to countries wanting to provide quality broadband to its citizens. A survey research approach was employed to achieve the overall aim and objective of this research. This was conducted using the response of 133 participants located in various boroughs in the UK. The results of the survey show that quality, though desired by many, has been short-changed by the desire to have access to the Internet via broadband at the lowest cost possible. However, this has not encouraged some consumers to switch to broadband from dial-up service despite continuous low prices being offered by service providers. Furthermore, the results also indicated that focusing on broadband quality will improve and promote investment in broadband capacity and decrease the uncertainty in consumer demand for applications such as multi-media content delivery, enhanced electronic commerce and telecommuting that exploit broadband access

Space-Based Information Infrastructure Architecture for Broadband Services

This study addressed four tasks: (1) identify satellite-addressable information infrastructure markets; (2) perform network analysis for space-based information infrastructure; (3) develop conceptual architectures; and (4) economic assessment of architectures. The report concludes that satellites will have a major role in the national and global information infrastructure, requiring seamless integration between terrestrial and satellite networks. The proposed LEO, MEO, and GEO satellite systems have satellite characteristics that vary widely. They include delay, delay variations, poorer link quality and beam/satellite handover. The barriers against seamless interoperability between satellite and terrestrial networks are discussed. These barriers are the lack of compatible parameters, standards and protocols, which are presently being evaluated and reduced

Aiding compliance governance in service-based business processes

Assessing whether a company's business practices conform to laws and regulations and follow standards and SLAs, i.e., compliance management, is a complex and costly task. Few software tools aiding compliance management exist; yet, they typically do not address the needs of who is actually in charge of assessing and understanding compliance. We advocate the use of a compliance governance dashboard and suitable root cause analysis techniques that are specifically tailored to the needs of compliance experts and auditors. The design and implementation of these instruments are challenging for at least three reasons: (1) it is fundamental to identify the right level of abstraction for the information to be shown; (2) it is not trivial to visualize different analysis perspectives; and (3) it is difficult to manage and analyze the large amount of involved concepts, instruments, and data. This chapter shows how to address these issues, which concepts and models underlie the problem, and, eventually, how IT can effectively support compliance analysis in Service-Oriented Architectures (SOAs). © 2012, IGI Global

Safety Sufficiency for NextGen: Assessment of Selected Existing Safety Methods, Tools, Processes, and Regulations

NextGen is a complex socio-technical system and, in many ways, it is expected to be more complex than the current system. It is vital to assess the safety impact of the NextGen elements (technologies, systems, and procedures) in a rigorous and systematic way and to ensure that they do not compromise safety. In this study, the NextGen elements in the form of Operational Improvements (OIs), Enablers, Research Activities, Development Activities, and Policy Issues were identified. The overall hazard situation in NextGen was outlined; a high-level hazard analysis was conducted with respect to multiple elements in a representative NextGen OI known as OI-0349 (Automation Support for Separation Management); and the hazards resulting from the highly dynamic complexity involved in an OI-0349 scenario were illustrated. A selected but representative set of the existing safety methods, tools, processes, and regulations was then reviewed and analyzed regarding whether they are sufficient to assess safety in the elements of that OI and ensure that safety will not be compromised and whether they might incur intolerably high costs

Semantic discovery and reuse of business process patterns

Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse
