Present situation in globalizing economy when margins are falling is forcing businesses to change traditional supply chains to adaptive supply chain networks. Adaptive supply chain network - a network of user oriented enterprises, sharing resources and knowledge, in order to be able to react smoothly to constantly changing and competitive environment. Currently market leading supply chain management systems aren't providing profitable opportunities to organize adaptive supply chain networks. In order to elevate the competitiveness of small and medium enterprises by increasing the effectiveness of their business processes, a supply chain management system, which could make use of e-business concepts, has to be developed. In order to do so, an integrated supply chain network model was created, which serves as a conceptual foundation and provides guidelines for creation of adaptive supply chain network management systems. Because members of adaptive supply chain network are separate enterprises, they must share data by the means of internet. It is purposeful to use web services to implement this requirement, because they enable communication of software systems, which were developed on different platforms or using different programming languages. During a project such a system was developed and it provides an opportunity to integrate an enterprise into an adaptive supply chain network. The solution, which is operating as a set of web services and is implemented in Java, can... [to full text]

Sparti elektroninės komercijos plėtra ir augimas natūraliai sąlygojo modernių, online aplinkai pritaikytų atsiskaitymo, mokėjimo sistemų atsiradimą. Itin svarbu tai, kad technologijų tobulėjimo pasėkoje ne tik eksponentiškai išaugo perduodamos informacijos kiekis, tačiau pakito pačios informacijos prigimtis – ji pati savaime, per se, tapo ekonominę vertę turinčiu objektu. Vartotojų noras saugiai atsiskaityti internete įtakojo, kad „online“ aplinkoje mažėja naudojimas tokių tradicinių atsiskaitymo priemonių kaip mokėjimo kortelės. Interneto vartotojai vis rečiau pasitiki šiuo mokėjimo įrankiu, kadangi vartotojai, pateikdami pardavėjui savo mokėjimo kortelės duomenis, susiduria su neteisėta šių duomenų panaudojimo rizika. Šiame darbe pateikiamas siūlomas dalinai prijungties režime veikiančios elektroninių pinigų cirkuliacijos sistemos, skirtos mažiems ir vidutiniams mokėjimams, modelis, besiremiantis sukurta Payword mikromokėjimų sistemos koncepcija. / Fast developing and growing of e-commerce determined the coming of modern payment systems. Intention of users to pay safely on the internet impacted the decrease of use of traditional payment system such as credit cards. It’s started to look for and design alternative ways of payment, such as smart cards systems or systems using software for saving monetary value. Traditional payment systems currently used by most e-commerce sites are not suitable for high volume, tiny valued transactions. There is a need of payment system that is cost effective, secure and easy to use. The purpose of this work is to propose a model of semi-online electronic money circulation system for small and average payments, which is based on a concept of R. Rivest and A. Shamir created micropayment system called Payword. The proposed model’s architecture and protocol are explained in detail. To increase performance of the system there was done a research to find out which hash algorithm and electronic signature algorithm is most suitable for the proposed model.

Globalizacija, labai sparti informacijos ir ryšių technologijų, elektroninių ryšio paslaugų bei Interneto plėtra ir išplitimas lėmė, kad šiuolaikinis pasaulis susiduria su nuolatiniais aplinkos pokyčiais. Permainos vyksta taip greitai, kad tai, kas šiandien yra nauja, rytoj gali būti antikvaras, todėl toks dinamiškas ir intensyvus gyvenimo tempas lėmė, kad informacijos ir žinių faktoriaus vaidmuo tampa lemiamas visose sferose. Informacijos ir ryšių technologijų raida leidžia vis labiau efektyviai ir greitai skleisti informaciją bei žinias. Jas priimti, apdoroti ir perduoti, turint tinkamus įgūdžius, tampa labai paprasta ir efektyvu, nes informacijos ir žinių tinkamas naudojimas suteikia konkurencinio pranašumo. Toks spartus gyvenimas, nepastovumas ir greiti pokyčiai skatina dinamiškumą ir permainas socialinėje bei ekonominėje aplinkoje, todėl atsiranda poreikis kurti naują Informacijos visuomenę, kuri sugebėtų efektyviai veikti tokioje dinamiškoje aplinkoje ir tinkamai išnaudoti informacijos bei IRT potencialą. ES supratimu informacijos visuomenės terminas apibūdina ekonominius, socialinius pokyčius, kuriuos sukelia IRT plėtra ir intensyvus jų naudojimas Nuolatinė IRT plėtra leidžia pastoviai kurti naujas elektronines paslaugas ir produktus, bei sudaro sąlygas naujiems informacijos ir žinių naudojimo ir pritaikymo būdams, kurie užtikrina konkurencingumą ir skatina ekonomikos augimą. Kiekviena valstybė privalo to siekti ir investuoti į inovacijas IRT sektoriuje, tačiau turėtų...

One of the European Union (EU) objectives is to make sure that Europe's business, governments and citizens continue to play a leading role in shaping and participating in the global knowledge and information based economy The world economy is moving from a predominantly industrial society to a new set of rules - the information society. What is emerging is often referred to as the new economy. It has tremendous potential for growth, employment and inclusion. Yet Europe is not fully exploiting this potential as it is not moving fast enough into the digital age. The underpinning dynamics of the new economy are strong. Digital technologies make accessing, processing, storing and transmitting information increasingly cheaper and easier. The sheer scale of information available creates huge opportunities for its exploitation through the development of new products and services... [to full text]
