The Hungarian media shows very contradictory pictures of women today: Successful career women enjoying material well-being is one picture, while the careful mother not working outside the home, keeping together the family is another one. Between these two contradictory poles there are almost no other female actors in the media. Life produces something different. In spite of the fact that there was a big loss of jobs in 1990s, and women’s activity rate decreased while the unemployment rate increased compared to before the 1990s, woman with duel roles are still accepted and common. The first female task is looking after the family and the second one is working outside the home and earning money. In many cases there is a third role: studying in distant or evening courses. In the next chapters we go deeper into this topic. We analyse the different aspects of female labour market positions, and show some relevant characteristics of governmental parental benefits and childcare support, and examine how the new pension system effects women. We also have a quick look at trade unions and show their lack of activity around gender issues. In the labour market analysis of the position of women we use labour force surveys, institution-based labour statistics, and unemployment registers. The Appendix 1 contains short descriptions of these data sources.

A dolgozat a visszutas logisztikát, az újrahasznosítást igyekszik beilleszteni a vállalati termeléstervezés keretei közé. A szükséglettervezési rendszerek (material requirements planning, MRP) célja a készletek és beszerzendő anyagok, alkatrészek időben ütemezett gyártásának és beszerzésének megtervezése. A klasszikus MRP rendszereket az utóbbi időben próbálja a tudomány az újrahasznosítással kibővíteni. Mivel ebben az esetben az új, és újrafelhasználható anyagokat külön kell nyilvántartani, ezért az MRP-táblák és készletek növekednek. A rendelési tételnagyságok meghatározása is nehezebb, összetettebb tételnagysághoz vezet. A dolgozatban egy visszutas logisztikai készletmodellt ismertetünk, valamint annak dinamikus kiterjesztését, amely alapja lehet az SAP-ba beépíthető rendelés állomány meghatározó heurisztikának. ____ The aim of the paper is to extend production planning with reverse logistics and reuse. Material requirements planning (MRP) systems plan and control invetory levels and purchasing activities of the firm. In the last decade scientists on this field try to involve reverse logistics activities in MRP systems. Size of MRP-tables is growing in this case because of the alternative use of newly purchased products and reusable old items. Determination of order quantities will be more complex with these two modes of material supplies. An EOQ-type reverse logistics model is presented in the paper with a dynamic lot size generalization. The generalized model can be seen as a basic model to build in production planning and control system like SAP.
