The notations of business processes can be used to design IT systems. If we want to reduce the expenses and the amount of mistakes of the bigger projects we need to create additional models, which can help us to find out whether the business processes are well understandable and correct. The question is how to reduce the expenses for creation of business process models. The purpose of thesis is to answer to this question: how to transform BPMN models to PLA method. The basic concepts was gathered and systemized, that will allow us to talk about business processes in a structured way. Also was made analysis of business process modeling languages (BPMN (Business Process Modeling Notation) and UML (Unified Modeling Language)). Also was described piece-linear aggregate (PLA) method, which is used for creation of dynamical models of business process. Was made BPMN model of ATM (automatic teller machine) business process, which was transformed to PLA model. The results of transformation was systemized and was made general requirements how to transform BPMN models to piece-linear aggregate.

Visual languages are used for understandability of business analysis, modeling and computerization processes for business analysts as soon as system developers. The advantages of visual modeling are standard notation, unified concepts, and intuitive use. There is no single language suitable for all phases of business process evolution. Three languages were analyzed: UML 2.0, BPMN and BPEL4WS, with regards to their possibilities to represent and execute e-business processes. It is proposed to extend UML 2.0 with BPMN stereotypes for e-business process modeling with succeeding transformation to execution language BPEL. The exclusive feature of proposed way of modeling lies in integration of business process model with object types of problem domain. In order to test the proposed method, scenario for modeling was prepared and three models were designed: two models using UML 2.0 notation, and one model using UML extended with BPMN stereotypes. Models were compared to show new method advantages. For implementation of proposed method, UML CASE tool MagicDraw was extended with stereotypes required for the proposed method of modeling. Extended user interface was proposed for specification of business rules governing the e-business process.

Siekiant maksimizuoti organizacijos pelną ir pagerinti jos veiklos rezultatus reikia efektyviai išnaudoti visus organizacijoje vykstančius verslo procesus. Tai padaryti galima naudojant įvairias verslo procesų valdymui skirtas kompiuterizuotas informacines sistemas. Projektavimo tikslas – sukurti ir aprašyti statinius ir dinaminius organizacijoje vykstančius procesus. Verslo procesams projektuoti ir analizuoti kuriant informacines sistemas, ypač jeigu jos didelės, reikia specialių projektavimo metodologijų ir priemonių, kurios šiuos procesus palengvintų, padarytų lengviau suvokiamais ir paspartintų darbą. Darbe išanalizuoti verslo procesų projektavimo būdai kuriant informacines sistemas: Petri tinklai, UML ir hibridinis Petri tinklų ir UML projektavimo metodas, pateikti jų aprašymai, savybės, galimybės. Taip pat išanalizuota organizacijose vykstantys verslo procesai. Bene daugiausia dėmesio skirta į rezultatyvumo ir žinių bei informacijos valdymo procesą, kadangi nuo jų priklauso organizacijos veiklos rezultatai. Organizacija projektuojama pradedant nuo bazinio - rezultatyvumo proceso. Todėl teorinių tyrimų aprašymo dalyje nagrinėjama pasirinkto rezultatyvumo verslo proceso projektavimas aprašytais Petri tinklų, UML bei hibridiniu metodais. Eksperimentinių tyrimų dalyje pasirinkta organizacija UAB „Proringas“, išanalizuoti joje veikiantys verslo procesai, sumodeliuotos skirtingų procesų valdymo sistemos, kurios sujungtos ir projektuotos trimis analizuojamais metodais. Metodai... [toliau žr. visą tekstą] / For maximising profit of organization and increasing its efficiency of activities must be used all business processes used in organization. The purpose of designing – to create and describe static and dynamic processes in organization. For projecting and analysing business processes while created information systems it is needed special modelling methodologies and tools that would make easier and more understandable those processes and would increase efficiency of work. There is analysed business processes design in this work while are created information systems: Petri-Net, UML and hybrid Petri-Net and UML design project methods, listed their descriptions, characteristics and possibilities. Also there are analysed business processes that take place in organization. Specialized attitude to information resources managing suppose demand of business system information, its usage and value by addressing adequate order for software. According the management position it must be coordination of data and information processing capabilities with creative person capabilities and technologies. Organization designed starting from processes and from them must be designed efficiency process. So in theoretical part it is analysed by chosen efficiency business process design described by Petri-Net and UML methods. In the part of experimental research selected organization - Joint stock company Proringas, analised business processes in it, modelled business processes that takes part in it... [to full text]

Magistro darbo objektas – verslo valdymo sistemos diegimas. Darbo tikslas – nustatyti verslo valdymo sistemų diegimo pagrindinius sėkmės faktorius atskiruose diegimo etapuose įmonėms Lietuvoje ir pateikti pasiūlymus didesnei VVS diegimo sėkmei užtikrinti. Pagrindiniai darbo uždaviniai: teoriškai išanalizuoti įmonės veiklą, išskirti ir apibrėžti jos funkcines sritis bei verslo procesus, išnagrinėti tarpusavio ryšius; išnagrinėti bendrus verslo valdymo sistemų bruožus, jų atsiradimo priežastis, raidą, išskirti pagrindinius diegimo etapus bei metodikas; apžvelgti Lietuvoje naudojamų verslo valdymo sistemų rinką; identifikuoti ir išnagrinėti pagrindinius mokslinėje literatūroje minimus VVS diegimo sėkmę lemiančius faktorius; kokybinio tyrimo būdu atlikti kritinių sėkmės faktorių analizę Lietuvos įmonėse; pateikti pasiūlymus VVS diegiančioms įmonėms didesnei diegimo sėkmei užtikrinti. Verslo valdymo sistemos diegimas yra pripažįstamas kaip problemiškas laiko ir biudžeto paskirstymo atžvilgiu. Šių sistemų diegimai yra sunkiau valdomi nei kiti IT projektai. Yra atlikta daug tyrimų, analizuojančių kritinius sėkmės faktorius verslo valdymo sistemos diegime. Vis dėlto dauguma tyrimų nagrinėjančių kritinius sėkmės faktorius apsiriboja pačių faktorių identifikavimu, o ne jų pritaikymu konkrečiam etapui ar tarpusavio ryšiais. Reikia pažymėti, kad Lietuvoje apie verslo valdymo sistemų diegimus publikuojami tik pavieniai straipsniai specializuotuose periodiniuose leidiniuose, o kritinius...

ERP systems are integrated enterprise-wide software packages that uses a modular structure to support a broad spectrum of key operational areas of the organization. They are widely acknowledged as having the potential to radically change existing businesses by bringing imporements in efficiency and the implementation of optimized business processes. ERP systems link together an organization's strategy, structure, and business processes with IT system. Although the technical risk from developing software is considerably reduced, risk during implementation is associated with aligning the processes with those of the software package and the corresponding change management and software configuration issues. The analysis of the cases reveals that in addition to standard project management critical success factors, there are other factors that need to be taken into account in ERP implementation. ERP systems have become popular means for both large and medium-size organizations to overcome the limitations of alienated and incompatible legacy systems. ERP systems are designed as an integrated set of software modules, all linked to a common database, handling a host of corporate functions such as finance, human resources... [to full text]
