There is a growing interest for scientists to aid decision makers in their difficult task of development planning of their countries. This could be achieved using models of both national and international (global) nature. Modelling of socio-economic systems has reached a complex state that a comparative study, defining the important measures for selecting a model fora specific application, is becoming an urgent need. When considering developing countries, the situation will be more complicated. An important question will arise, whether these models are valid for developing countries? In other words, can they be adapted to fit the needs of developing countries? In this paper, some of the essential features of socio-economic models will be presented. The evaulation of some of the reported models is considered taking into consideration the possibilities of adapting such models to fit the needs of developing countries. Finally, the problem facing the modelling of developing countries economics are discussed.

In this paper, education and training schemes needed to achieve a certain level of technological development is presented. The general strategy will be introduced first, then specific experiences of both professional educational organizations and industrial organizations will be given in some details. A discussion about the role and importance of education in information systems will be also presented.

There is a variety of units existing in the Egyptian Iron & Steel Complex In Helwan area that has been installed in several steps, during a period of two decades. Different suppliers and companies took part in the delivery, erection, and putting into operation of production and auxiliary components of the plant. This situation created difficulties in maintenance, spare parts availability, also some problems in the programming for preventive maintenance duties. In this paper, an information system was developed and adapted to suit the local conditions with the aim to control maintenance viork spare parts production in the local workshops, and to have an inventory control over spares and consumption materials. Such a system was developed taking into consideration the relations between dependent shops, loading of adjacent shops, besides, looking after safe stock level of spares without overloading the economy of the plant. The success of such a system depends upon data collection, continuous information flow from different prcduction shops, and is mainly dependent on people monitoring the system and the efficient computer centerin the plant.

A general review of the Industrial planning sector in the Arab World is presented. A sectorial analysis is given showing the interaction between the different concerned Governmental Organization together with their impact on the planning process. The role of the public and private sectors has been discussed with special emphasis on the hletallurgical Industries as an example. The interaction between national and regional planning organizations is considered.

Developing countries suffer from the conflict between limited resources and increased demand for the attainment, by the entire population, of the highest level of health. This is further comnlicated by the fact that all segments of the society are affected by the system for protecting the life and health of human beings, and in turn, affect its operation. A compromize could be achieved through the optimal use of available resources to obtain the reauired standard of health care delivery. This paper deals with dynamic modelling for optimal planning in health care systems and associated problems. Given a deviation of the health care state from a required standard, the model describes the optimal trajectory to minimize a quadratic cost of this deviation and the corresponding investment in a fixed planning period. By determining the required strategy for manpower delivery, the necessary hardware and overall cost of the system could be estimated. To make possible the incorporation of the model into a global national planning model, the interaction with demographic, educational and economic sectors is taken into consideration. However, the model is designed to work independently.
