Purpose The purpose of this paper is to present the results of surveys conducted in the field of level of e-commerce services quality. The criteria of quality of e-commerce services were identified. On this basis the hierarchy of importance of the adopted criteria for e-commerce service quality were proposed. Design/methodology/approach The level of customer satisfaction was measured using the Servqual method. In order to compare two groups: the quality of e-commerce services before purchase and the quality of e-commerce services after the purchase, a student’s t-test was used. To check if the relations between variables are sufficient to carry out the factor analysis (sampling adequacy), the Keizer–Meyer–Olkin test was used. The scope of the research included 23 selected criteria of customers satisfaction. Findings A comparison of the Servqual weighted and unweighted results shows that customers valued the guarantee/safety dimension the most. It can therefore be expected that customers perceive e-commerce services with increasing trust and consider them increasingly reliable which is also confirmed by the growing tendencies in the forecasts of e-commerce services in Poland. Originality/value Research allows to know the opinion and expectations related to the quality of services provided in the analysed area and to develop the strategy of company. The most important indicator of the quality of e-commerce services remains reliability (weighting = 0.34). However, the noticeable difference in opinions concerns the tangible elements index compared to the results of the Berry and Parasuraman team and amounted to 0.20.
The principal objective of the research was to determine the influence exerted by the implementation of standard quality management systems on the improvement of selected logistics processes in small and medium-sized enterprises, which operate in the textile industry. Empirical research was carried out by the authors in the year 2017 on a group of small and medium-sized enterprises that operate in the textile industry in Poland and Slovakia. The research involved 33 organizations (20 Polish, and 13 Slovak ones). The research process and the analysis of the acquired results made it possible to address the research questions posed and to state, among others, that standardized quality management systems exert a relatively large influence on perfecting selected subsystems and logistic processes in the researched organizations.
Alternative fuels (refuse-derived fuels—RDF) have been a substitute for fossil fuels in cement production for many years. RDF are produced from various materials characterized by high calorific value. Due to the possibility of self-ignition in the pile of stored alternative fuel, treatments are carried out to help protect entrepreneurs against material losses and employees against loss of health or life. The objective of the research was to assess the impact of alternative fuel biodrying on the ability to self-heat this material. Three variants of materials (alternative fuel produced on the basis of mixed municipal solid waste (MSW) and on the basis of bulky waste (mainly varnished wood and textiles) and residues from selective collection waste (mainly plastics and tires) were adopted for the analysis. The novelty of the proposed solution consists in processing the analyzed materials inside the innovative ecological waste apparatus bioreactor (EWA), which results in increased process efficiency and shortening its duration. The passive thermography technique was used to assess the impact of alternative fuel biodrying on the decrease in the self-heating ability of RDF. As a result of the conducted analyses, it was clear that the biodrying process inhibited the self-heating of alternative fuel. The temperature of the stored fuel reached over 60 °C before the biodrying process. However, after the biodrying process, the maximum temperatures in each of the variants were about 30 °C, which indicates a decrease in the activity of microorganisms and the lack of self-ignition risk. The maximum temperatures obtained (>71 °C), the time to reach them (≈4 h), and the duration of the thermophilic phase (≈65 h) are much shorter than in the studies of other authors, where the duration of the thermophilic phase was over 80 h.
Recent years have seen a dynamic growth of ecommerce. This links to technological developments, an increase in the number of people who have access to and actively use the Internet, and the use of mobile devices. The aim of the paper is to present the results of a questionnaire survey of the factors behind the development of e-commerce services. Besides, the paper defines the interdependence between the frequency of internet shopping and the logistic aspects of e-commerce. A hierarchy is also established of the degree of satisfaction as regards the quality criteria of e-commerce services. The analysis covers data from a questionnaire survey of 100 customers using ecommerce in Poland. The respondents were customers using e-commerce services aged between 20 and 24. The questionnaire was based on a five-point Likert-type scale of between 1 and 5. The survey was qualitative and nationwide. The analysis was done using the Statistica 10 software. The Pearson correlation was chosen from amongst the methods available to determine the impact between the surveyed variables. Firms that provide e-commerce services aim to fulfil the ever increasing needs and expectations of their customers. They attach a lot of importance to the quality of customer service which is demonstrated by the high scores awarded by the respondents.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
