ERP inside Large Organizations

Many large companies in Romania are still functioning without an ERP system. Instead they are using traditional application systems built around the strong boundaries of specific functions: finance, selling, HR, production. An ERP will offer lots of advantages among which the integration of functionalities and support for top management decisions. Although the total cost of ownership is not small and there are some risks when implementing an ERP inside large and very large organizations, having such a system is mandatory. Choosing the right product and vendor and using a correct risk management strategy, will ensure a successful implementation.Enterprise Functions, ERP Functionalities, Process Lines and Solutions, Cost Implementation, Total Cost of Ownership, Risk Management, Active Global Support, ERP Advantages, Success Factors, Return of Investment

COMPANIES ECONOMY IN CONTEXT OF THE ECONOMIC CRISIS

In this article I try to express components of the market economy which may affect an organization of the companies into a period whith decline and resignation reign in human activities. The economic crisis that is the a current world is the climax of financial turmoil which make integral part a normal legislative and the economic calculation which configures a demand and supply of goods.organizational arrangements; company; contracts; legislation; demand; supply; Microeconomics; economic calculation

Relative quantum field theory

We highlight the general notion of a relative quantum field theory, which occurs in several contexts. One is in gauge theory based on a compact Lie algebra, rather than a compact Lie group. This is relevant to the maximal superconformal theory in six dimensions.Comment: 19 pages, 4 figures; v2 small changes for publication; v3 small final changes for publicatio

Topological dualities in the Ising model

We relate two classical dualities in low-dimensional quantum field theory: Kramers-Wannier duality of the Ising and related lattice models in $2$ dimensions, with electromagnetic duality for finite gauge theories in $3$ dimensions. The relation is mediated by the notion of boundary field theory: Ising models are boundary theories for pure gauge theory in one dimension higher. Thus the Ising order/disorder operators are endpoints of Wilson/'t Hooft defects of gauge theory. Symmetry breaking on low-energy states reflects the multiplicity of topological boundary states. In the process we describe lattice theories as (extended) topological field theories with boundaries and domain walls. This allows us to generalize the duality to non-abelian groups; finite, semi-simple Hopf algebras; and, in a different direction, to finite homotopy theories in arbitrary dimension

Dirac Families for Loop Groups as Matrix Factorizations

We identify the category of integrable lowest-weight representations of the loop group LG of a compact Lie group G with the linear category of twisted, conjugation-equivariant curved Fredholm complexes on the group G: namely, the twisted, equivariant matrix factorizations of a super-potential built from the loop rotation action on LG. This lifts the isomorphism of K-groups of [FHT1,2, 3] to an equivalence of categories. The construction uses families of Dirac operators.Comment: 6 pages, research announcement. The complete details and background will appear in a future pape

Impact of Crisis on Logistics Management

Is the current situation facing the whole world and we need to adapt to withstand a fierce weather. Because the supply, which can be seen both as a sale (the manufacturers buy from suppliers) as well as a purchase (customers are supplied by producers) is the center of activities, we believe that a interpretation and a strategic direction to increase the competitiveness of extended supply chain, represents an initial starting point to save the current situation. We must understand that do not survive the nicest, smartest or the strongest, is the future of those who adapt best to change. In the global crisis context we must consider first the potential and not the market. Apparently the market is in a total collapse, but the potential still exists, even at minimum capacity it should work. Now they will be able to support only companies that eliminate almost all their losses and best manages their resources and activities.supply chain management; global crisis; restarting the business; procurement cycle.

Risk Management in Public Key Infrastructure

Nowadays it is almost impossible not to hear or read about the risks of using computer systems. Top management is becoming more interested in risk management process and their analysis regarding the use of information technologies within their organization. This is due primarily to the Internet boom and high level of dependence of their business to information systems. Risk management is the process that allows IT managers to balance the operational and economic costs of protective measures and obtain assets in mission capability by securing the IT systems and data that help their organizations performances. In this paper we present the risk management processes, the main services offered by the Public Key Infrastructure and security risks that may arise in implementing Public Key Infrastructure.risk management; public key infrastructure; PKI services; PKI risks.

Management of Public Acquisition in the Context of Public-Private Partnership

With Romania's integration in the European Union it has been compelled to align its national legislation with the European one. This change also applies in regards with public acquisitions where legislation change implies facilitating free movement of merchandise. The means of public acquisitions which Romania was using before joining the European Union can no longer be used in the current context. Thus, current legislation must be adapted to European specific requirements while keeping the national and regional particularities. The acceptance of public-private partnership, successfully implemented in many European countries, is one direction in which public acquisition performances can be enhanced. Public-private partnership benefits derive from accepting the provider (private organization that provides goods and services) - beneficiary connection (public organization purchasing goods and services) as a partnership in which the seller-buyer relationship is seen as a win-win relationship with repetitive nature (over a long period of time).management of public procurement; public-private partnership; the annual procurement; decentralization of public administration.
