The Multicriteria Assessment Methodology of the Decision Support System Implementation Effectiveness

The multi-criteria assessment methodology of implementation effectiveness of information systems illustrated by an example of decision support system (DSS) realized in w information technologies is presented in the article. The assessment of DSS under consideration takes place using the knowledge recorded in the form of fuzzy neural network, collected in an enterprise, on the basis of earlier realized implementations of other information systems. A model of retrieved DSS is expressed by means of a set of functionalities serving business processes of the enterprise under consideration. A model of implementation undertaking determined by means of a set of preparatory actions for the implementation and a set of directly implementation and exploitation actions is built for the retrieved DSS as well. Furthermore, a vector determining a current and planned implementation state of a set of DSS functionalities in the enterprise at time moments, before and after the commencement of planned implementation of the retrieved DSS is built. A concept of trapezoidal fuzzy numbers is used in building DSS models. An adjustment of fuzzy parameters of DSS models takes place by means of geometrical method of maximum absolute error points. A presented methodology enables to execute a multi-criteria effectiveness assessment of planned undertaking in relation to subjective criteria established by the enterprise (preferred time, cost and values of priority indexes). Additionally, the knowledge collected on the basis of earlier realized implementations of information systems and applied imprecise description of parameters taking into account errors made in their estimation in the past is used.

The Multicriteria Selection Methodology of the Decision Support System

An issue of building a tool orientated to the support of selection process of decision support system (DSS) for the sector of small and medium enterprises is presented in the article. A group method of data handling (GMDH) whose application allows to objectives a search process of required DSS, with assumed costs and other existing resource limitations, is proposed for this purpose. The article is devoted to a problem of GMDH adjustment to solving the tasks related to the selection of a required system from among the information systems of DSS class, according to the criteria determined by a future user of this system. The GMDH takes into account among other things such assumptions as: a precise description of dependences between input and output data in a specified time horizon, independence of the user's knowledge (the values of observed data from the past registered in the base are the input data) and minimization of modelling errors (the selection of solutions takes place by means of a selected evaluation rule of quality estimation).

Computer Integrated Enterprise in the MRP/ERP Software Implementation

The aim of this elaboration is to present selected methodology, application and design issues connected with the process of complex enterprise informatization in the implementation process of an IT system. Role of the integration process in economic information processing and directions of integration activities in the scope of the IT systems of the enterprise are presented in the first part of this elaboration. Afterwards, technical features of an integrated IT system are characterized. Thesis that particular systems are comparable in the scope of functionality of the basic areas of activity of the enterprise, such as: accounting, material and stock planning, sales and invoicing, human resources, wages, can be formulated on the basis of the national portfolio of ERP (Enterprise Recourses Planning) packages. On the other hand, the cost of license purchase as well as the implementation activities, reaches the level from tens of thousands to few million PLN. Differences in the levels of investments are determined with: scope and complexity of the endeavor, functionality and system architecture as well as the cost of extension and modification of provided program modules.

Management Information in Administration Systems

Management information is the basis for decision making. The essential meaning of the management information is noticed in the administrative systems, through the analysis of the character and usefulness of the management information, as legal information that is published in the form of internal and external legal acts. Specification of the legal acts, connected with the activities of the administrative unit, requires undertaking of certain methodology of the conduct. Process approach, based on the specification of the processes realized in the administrative unit and related legal acts, is suggested. Case study related to a faculty at the University is an example of the use of presented proposal.
