Cell formation (CF) problem is one of the most important decision problems in designing a cellular manufacturing system includes grouping machines into machine cells and parts into part families. Several factors should be considered in a cell formation problem. In this work, robust optimization of a mathematical model of a dynamic cell formation problem integrating CF, production planning and w...

The increase in female employment and participation rates is one of the most dramatic economic changes to have taken place during the last century. However, while the employment rate of married women more than doubled during the last fifty years, that of unmarried women remained almost constant. In order to empirically analyze these trends we divide the paper into two parts: In the first, we em...

This paper presents a mathematical programming model for dynamic cell formation to minimize changeover-related costs (i.e., machine relocation costs and machine setup cost) and inter-cell material handling cost to cope with the volatile production environments in apparel manufacturing industry. The model is formulated through findings of a comprehensive literature review. Developed model is val...

Abstract: The labor admission test is a very useful screening test in early labor to detect compromised fetus on admission. It is used to select the woman in need of continuous fetal electronic monitoring during labor. It is a dynamic screening test to study fetal oxygenation at the time of admission of the mother in labor room. The labor admission test is a very useful screening test in early ...

T his study investigated the effect of international labor migration on Iran’s economy using a neo-classical growth model with the assumption of labor heterogeneity within the framework of dynamic stochastic general equilibrium model. After solving the model, the obtained equations were linearized and different values were assigned to the parameters according to Iran’s economy inform...

Labor hoarding is a widely believed empirical behavior of …rms and a prominent explanation for procyclical labor productivity. Conventional wisdom attributes labor hoarding to labor adjustment costs. This paper argues that the conventional wisdom is inadequate for understanding labor hoarding because it ignores the role of inventories. Since idle labor can be used to produce inventories, why do...
