ABC Analysis in an Internet Shop: A New Set of Criteria

This article presents a model of ABC analysis tailored for internet shops. The standard set of criteria is expanded to cover e-commerce specific characteristics, such as the number of product views, search engine rankings and product links via a recommendation system..The proposed new methodology is applied to real data from an internet bookstore in Poland. A comparison with the results of a standard, not internet-oriented ABC analysis shows the advantage of using the new set of criteria.ABC analysis, internet shop, inventory control

Genetic algorithms in seasonal demand forecasting

The method of forecasting seasonal demand applying genetic algorithm is presented. Specific form of used demand function is shown in the first section of the article. Next the method of identification of the function parameters using genetic algorithms is discussed. In the final section an example of applying proposed method to forecast real demand process is shown

Evolution of polish E-commerce - main trends and perspectives

The aim of this paper is to present main phases of Polish e-commerce development and to show its major trends. The author also tries to predict future directions of its development. The whole e-commerce process of development is divided into five phases. The first part of the paper presents the beginnings of Polish e-commerce. Then the following stages of development are discussed with presentation of some key figures e.g. percentage of individuals who ordered goods or services over the Internet. E-auctions phenomenon is analyzed and it’s influence on market is shown. WEB 2.0 philosophy in e-commerce is shortly described. Internet price comparison services are another occurrence which is analysed and specialization versus diversification of offer in Internet shops is discussed. The author shows the examples of Polish e-shops which changed their range of assortment. The last part of the paper shows future perspectives of Polish e-commerce and discusses probable ways of development into internationalization.e-commerce, Internet shop, Internet market

Analysis of on-line services

The aim of this paper is to analyse on-line services as well as to classify them and show their main advantages and disadvantages. In the first part of the paper the author proposes a short taxonomy of on-line services. Then the typical course of on-line services realization is presented and the revenue models in on-line services selling are analysed. Next the main advantages and disadvantages of on-line services selling are shown. The last part of the paper describes the examples of Polish on-line services. The services are divided into three categories: fully-automated, half-automated and not-automated.internet, on-line service, e-business

Genetic algorithms in forecasting of Internet shops demand

The general aim of this article is to present genetic algorithms as a tool, that can be used in de-mand forecasting in internet shops. First part of article identities factors, which have to be taken into consideration during analysing demand in internet shops, e.g. dispersion of demand, delivery time in-fluence and different e-marketing factors. Specific form of used demand function is shown in the next section of the article. Then genetic algorithm is defined by its genetic operators acting on bit strings (examples of the operators are: crossover, inversion, and mutation) and its method of credit allocation (fitness evaluation and selection). Next the method of identification of the function parameters using genetic algorithms is shown. The next part of article shows appliance of presented genetic algorithm. The advantages and disadvantages of proposed method are shortly discussed in summary.abc analysis, inventory control, internet shop,e-commerce

Degree of Economic Freedom and Relationship to Economic Growth and Human Development

Presented in this article is an analysis of the relationship between the Index of Economic Freedom and indices of economic growth, i.e. GDP per capita and the Human Development Index. The McPherson coefficient of correlation was calculated from several different perspectives. Described in the final part of the article is the testing of the hypotheses, while a short commentary on the results obtained is also presented.liberalism, economic growth, index of economic freedom

New Patterns of Protest and Revolution in the Age of Social Media

The article aims to analyse the role of social media in initiating and organising protest and revolutionary movements. Social media, particularly Facebook and Twitter, are widely believed to have been used by activists involved in the global wave of protests and revolutions after 2009. However, the assessment of their role wavers between technological determinism and minimising the impact of new technologies. Considering the current state of research, the author offers his answers to a number of questions: (1) To what extent and how are social media used in the processes of political communication, mobilisation and organisation of protest and revolutionary movements? (2) What is the relation between the old and the new media? (3) What is the relation between the online and offline dimension of collective action? (4) Why has the occupation of public space become the dominant tactic of protest and revolutionary movements in the age of social media?

Internet as Additional Distribution Channel - Synergy or Cannibalism

In this article main advantages and disadvantages of internet distribution as additional channel were analysed. The profs were divided into real, illusory and ambiguous factors. Then threats and disadvantages were shown. The important issues concerning additional internet channel were also described . The last part of the article contains presentation of the survey conducted in 616 Polish internet shops. The investigation concerns multi-channel distribution.distribution, internet shop, electronic commerce
