PLATFORM ONE4ALL IN IMPLEMENTING COMPUTER SOLUTIONS IN SERVICE ORIENTED ARCHITECTURE

The paper presents the foundations of building the systems of Service Oriented Architecture, SOA, their conception and influence on functioning of the whole enterprise. The newly presented platform one4all uses several computer products implementing as services for realization of the basic/fundamental business processes, communication and workflow management, project management, or the analysis of business activities.

DESIGN FOR A HYBRID SINGLE MULTI-LOAD AGV SIMULATION SYSTEM WITH ARTIFICIAL INTELLIGENCE CONTROLLER

This paper presents a simulation model of multi-load AGV system with artificial intelligence controller that is dedicated to be used in work transport control. The single AVG system with multi-load mean of transport is obtained assuming that the carrier capacity is big-enough to carry many lots at the single route. This model consists of a fuzzy logic and a genetic algorithms technics that minimize the total costs including transportation, setting up pick-up and/or delivery stations, and material handling devices. An example of \implementation of the
model is given. The simulation experiment is conducted and the results are presented.

PRODUCT CONFIGURATION USE CHOSEN ARTIFICIAL INTELLIGENT METHOD

Product adjustment to customer expectation, which means product customization, decides about its commercial success. Developing methods helpful in the early phase of product design is needed to product customization. The aim of this paper is to present application of knowledge-based systems (KBS) in product customization.

CYCLIC PROCESSES SCHEDULING

In everyday practice cyclic scheduling problems, especially timetabling ones arise in different application and service domains, e.g., class, train, crew timetabling, and so on. In many cases, e.g., caused by assumed slot size, imposing integer domain results in Diophantine character of problems considered. In that context some classes of cyclic scheduling problems can be seen as non-decidable (undecidable) ones. That means, since system constraints (i.e., parameter domains) determine its behavior (e.g., the space of feasible schedules), hence both system structure configuration and desired schedule have to be considered simultaneously. So, cyclic scheduling problem solution requires that the system structure configuration must be determined for the purpose of processes scheduling, yet scheduling must be done to devise the system configuration. In that context, this contribution provides discussion of some solubility issues concerning cyclic processes dispatching problems.

CALCULATION MODEL OF TEACHING COSTS IN A UNIVERSITY

A calculation model of teaching costs in a university is a system of guidelines, notions and relations to facilitate an assessment of the costs generated by individual university departments, majors, subjects etc. The existing calculation models based on the assessment of costs with the use of precision data prove to be ineffective in practice. The major drawback of these systems is the fact that it is not possible to take into account non-precision data in relation to cost generating factors (e.g. the number of didactic groups, hourly rates etc.). This article presents the author’s own proposal of a cost calculation model based on the formalism of fuzzy logics (with the use of the L-R representation). On the basis of the model proposed, it is possible to assess the costs of an academic subject with imprecise information concerning cost generating factors, or the values of those factors are assessed which imply the values set of the cost of a subject.
