This paper discusses the different research strategies on attainment and mobility presented by status attainment research and Boudon's recent book on education and mobility. It is argued that the interpretation of results of status attainment research is ambiguous because the static and linear models employed are not derived from consideration of the mechanism that produces observed outcomes. A...
One of the main arguments in the supply chain is integrated production-distribution planning. Integrated production and distribution of products in a supply chain plays an important role in reducing the costs of the chain. In this paper, a mathematical model for the integrated production-distribution problem in a three-level supply chain, including manufacturing plants, distribution centers and...
many research studies have been performed on forced convection (active) solar dryers for fruit and vegetables. a short survey of these showed that applying the forced convection solar dryer not only significantly reduced the drying time but also resulted in many improvements in the quality of the dried products. active indirect and mixed-mode thin layer solar drying experiments were conducted o...
In the context of globalization of economic development processes, the issue of determining the level of public welfare of economic agents is particularly burning. The object of ehis study is the process of assessing welfare of the economic entities system. The subject of the study is the instrumental and mathematical aspects of modeling and measuring the public welfare. The aim of the work is ...

in the real world, risk and uncertainty are two natural properties in the implementation of mega projects. most projects fail to achieve the pre-determined objectives due to uncertainty. a linear integer programming optimization model was used in this work to solve a problem in order to choose the most appropriate risk responses for the project risks. a mathematical model, in which work structu...
Background and aims: The job safety is one of the necessary aspects of efficiency in humane resource manangement of every organization, and if organizations enable to reduce the rate of job accidents and undesirable stress, then performance of workers become more efficient. Hence, job rotation is as good as a rest to increase efficiency. The aim of this research is to design an appropriate job ...
Airlines are going through very difficult times financially which has been triggered by fierce competition and current high fuel prices. To stay competitive, it is absolutely essential that they achieve high efficiency in the areas that have control over. Airlines start generating revenues while their aircraft are flying. Reducing aircraft turn-around times is an important goal with passenger b...
