Improving Organizations by Replacing the "Mechanical" Model
with the "Organic" one
Abstract: Organizations are currently viewed as artificial structures. However, in our opinion, organizations seem to match a biological structure much better. This paper explores this new approach with some interesting conclusions and results: organizations aim at perpetual exis-tence and continuous adaptation. We advance the ideas of organizational "instincts", organ-izational pathology and organizational optimization using genetic algorithms. In competitive markets, organizations are in a natural selection process, which actually is part of a natural genetic algorithm. This process may be simulated in an artificial multidisciplinary optimiza-tion environment, based on minimizing a Total Costs and Risks objective function. Unlike the gradient optimization methods, the genetic algorithms may be applied to such problems with thousands of degrees of freedom. This opens the way to the organizational structure optimiza-tion through genetic algorithms.
Task Flow Modeling in Electronic Business Environments
Abstract: In recent years, internet based commerce has developed as a new paradigm. Many factors such as "at home delivery", easy ordering, and usually lower prices contributed to the success of the e-commerce.
Abstract: Nowadays, innovation represents an essential ingredient within organizations for their survival in a strong competitive marketplace. Innovations emerging from R&D projects could represent key factors for the foundation of new businesses. Various supporting programs for establishing innovative start-ups within business incubators, as well as spin-offs within uni-versities are promoted by authorities at local and national levels. Statistics have shown that only a small percentage of these initiatives (around 30%) succeed to survive more than three years. There are various causes which keep the success rate only at this level, but a major one is the lack in understanding the complex nature of innovation by the people which initiate these businesses; they are mainly focused on technological innovation (product innovation). This paper is going to give a broader perspective on innovation, seeing it as an integrated model of product innovation, marketing innovation, production process innovation and busi-ness model innovation over their life-cycles. From this enhanced view of innovation, conse-quences on new product development are further analysed.
An Assessment of the Quality of the Romanian Urban Web Sites
Abstract: The local authorities are giving increasing prominence to provision of information online through websites. Seen in a wider perspective, the urban web sites play a key role in allowing every citizen to achieve their full potential and to participate fully in society. Con-versely, citizens’ awareness and expectations of Internet based online public services have also increased. Although the numbers of the different urban web portals have increased rap-idly in the last years, the success of these sites will largely depend on their accessibility and quality.

Within this article, I tried to present a short history, state of the art, as well as the tendencies on short term, for each of them.
A Cram of E-Learning Advantages and Disadvantages
Abstract: In today’s society, following the exponential development of ICT, the classical method of learning has undergone numerous changes. The emergence of the Internet has accelerated these changes due to its capacity to offer multiple possibilities of access to information, in-struction, all based on dynamic technologies, transparency and open dialogue. It can be well said that the Internet is turning into an arbiter for the access to education and culture, while eLearning is a new form of education that suggests itself as an alternative with a view to the needs of continuing training and knowledge.
Abstract: In this work is described a new complex training system, named SPprolog, intended for training and self-training in logic programming language - Prolog. This system includes elements related to Prolog and logic programming, and the elements of independent, com-plex, self-sufficient training system which is capable considerably to increase the quality of self-training, and to be effective assistant in training. The most useful application of the sys-tem can be in distance education and self-training. The main elements of SPprolog system are:

We also discuss here the development of such type of CAES as MULTIMEDIA and MULTIMEDIA&OFFICE Testing Methods - the CAES soft-ware - from the Information Society and Knowledge Society point of view.
Criteria for the selection of ERP software
Abstract: The implementation of an ERP software package is an important investment for an organization, which is characterized also by a high degree of risk. Selecting the most appro-priate software is a necessary condition for a successful implementation. This paper is de-scribing the major aspects of software selection in general and the relevant criteria in the case of ERP software.
Components of a Business Intelligence software solution
Abstract: Business intelligence (BI) is a business management term which refers to applications and technologies which are used to gather, provide access to, and analyze data and information about company operations. Business intelligence systems can help companies have a more comprehensive knowledge of the factors affecting their business, such as metrics on sales, production, internal operations, and they can help companies to make better business decisions.
SEO Techniques for Business Websites

Building a Data Warehouse step by step
Abstract: Data warehouses have been developed to answer the increasing demands of quality information required by the top managers and economic analysts of organizations. Their im-portance in now a day business area is unanimous recognized, being the foundation for de-veloping business intelligence systems. Data warehouses offer support for decision-making process, allowing complex analyses which cannot be properly achieved from operational sys-tems.
Paradigms of Intelligent Systems
Abstract: This paper approaches the subject of paradigms for the categories of intelligent sys-tems. First we can look at the term paradigm in its scientific meaning and then we make ac-quaintance with the main categories of intelligent systems (expert systems, intelligent systems based on genetic algorithms, artificial neuronal systems, fuzzy systems, hybrid intelligent sys-tems). We will see that every system has one or more paradigms, but hybrid intelligent sys-tems combine paradigms because they are made of different technologies.
Considerations on Accounting Intelligent Systems Importance
Abstract: Managers begin to realize the importance of artificial intelligence technologies for their organizations. Knowledge is today seen as the main organizational resource and that is what intelligent systems are about: manipulating knowledge. In this paper we highlight the main reasons that an accountant can bring to his managers to emphasize this idea: in-telligent systems are really needful in modern accounting.
The Logic Process Formalism of the Informational Domain
The performance of present-day informational technologies has two main properties: the universality of the structures used and the flexibility of the final user’s interfaces. The first determines the potential cover area of the informational domain. The second determines the diversity and efficiency of processing methods of the proceedings being automated.
Comparative Analysis of Business Object Approaches
Abstract: This paper presents a comparison of several technologies for developing distributed applications. The specific technologies into consideration are: one focused on COM/DCOM/COM + Microsoft technologies, Internet Explorer and ActiveX – and the other focused on Netscape, CORBA, JAVA/J2EE solutions.
Beyond the Object
Abstract: Object orientation (OO) is regained not only in all components of integrate develop-ment media but it remarks in the rest of software world from operating system to last applica-tion domain – of course, with different intensity and success. A clear prove of OO application in all situations is the development of a wide range of industrial applications.
Translating programming languages for intermediate codes
Abstract: Many of the important data structures used in a compiler are intermediate representa-tions of the program being compiled. Often these representations take the form of trees, with several node types, each of which has different attributes. Tree representations can be de-scribed with grammars, just like programming languages. For each grammar rule, there is one constructor that belongs to the class for its left-hand-side symbol. I simply extend the ab-stract class with a “concrete” class for each grammar rule. Each grammar rule has right-hand-side components that must be represented in the data structures.
More General Credibility Models
Abstract: This communication gives some extensions of the original Bühlmann model. The paper is devoted to semi-linear credibility, where one examines functions of the random variables representing claim amounts, rather than the claim amounts themselves.
Abstract: In this paper, we describe
a tool to aid in proving theorems about random variables, called the
moment generating function, which converts problems about probabilities
and expectations into problems from calculus about function values and derivates. We show how the moment generating function determinates the moments and how the moments can be used to recover the moment generating function. Using of moment generating functions to find distributions of functions of random variables is presented. A standard form of the central limit theorem is also stated and proved.
