This paper addresses the development of a fuzzy inventory control algorithm for inventory control in unpredictable environment. The anticipation principle is applied by using simulation models supported by inventory control algorithms, which were: fixed review period, Silver-Meal, Part period balancing, Least-unit cost, and a fuzzy inventory control algorithm based on fuzzy stock-outs, highest inventory level and total cost. The algorithms are tested on historic data. Simulation results yielded significant real cost savings.

Evaluation of a patient’s medical condition is an essential part of the health-care process. For this purpose, Henderson’s model of basic living activities is often proposed as a set of criteria in nursing. Despite its clarity and theoretical background, the model is only partially used in practice. In this paper, we present a hierarchical multi-attribute decision modelling methodology to increase the practical efficiency of the model. As a part of e-documentation, it supports systematic patient data gathering and evaluation in accordance with a process method of work.

The relationship between systems development and systems methodologies is discussed in this paper. It was supposed that profit and governmental organizations are systems comprised of Production, Management and Information Systems (IS), and that their quality performance is related to income generation, which will impact the overall GDP of a country. As a result, we have proved the dynamic hypothesis of a high correlation between GDP of Top 10 + Slovenia and R&D expressed by application of systemic methodology and simulation.

Several languages for the definition of specific scheduling problems are proposed in the literature. With a general scheduling-problem definition language, a comparison of different scheduling algorithms is enabled. The resource scheduling problem description language development procedure, including the syntax and semantic scheme of the language, is presented. An object-oriented methodology is used for the presentation of the resource scheduling model.

The system describes an exponential delay chain by means of the Systems Dynamics. The control strategy is determined according to the prescribed final states of a particular rank. In order to achieve the final states, the promotions policy between ranks and fluctuations could be changed by considering the boundaries of model parameters. The trajectory function is defined, which determines the approach to the final state. Numerical optimization was applied in order to provide a proper control strategy. The results show that some scenarios are not acceptable due to the problem of reachability.
