Further enhancement of the logistics targets achievement can be attained through development and use of so far locked flexibility potentials. Product structures with many variants allow for additional flexibility potentials due to the fact, that one component can become a part in one of many different final products variants for different customers. The challenge of this approach is to enable p...

today one of the major questions in the iranian economy is that do liquidity injected into the economy more effected productive activities or speculative activities .this study was conducted to compare the effects of liquidity growth on real sector and assets market bubbles in iranian economy during the period 1994(2)-2012(1). for this purpose, price index of four major assets in iranian econom...

There are essentially two ways to implement a Cellular Manufacturing System (CMS): physical and logical. In the first case, the machines are laid out in the floor space in dedicated manufacturing cells to exploit flow shop efficiency in processing part families, whereas in the second case machines are dedicated to process part families in a process layout. Logical oriented CMS are known as Virt...

This paper presents a two-phase clustering algorithm for machine-cell and partfamily formation in the design of cellular manufacturing systems. The proposed algorithm begins with the determination of initial cluster centers via a linear assignment method using the least similar group representatives in its first phase. A fuzzy C-means clustering method is followed in its second phase for part-f...

Case study of manufacturing of crystalline drug substance was used to see the application of Principal component analysis. Principal Component Analysis (PCA) is one of the multivariate methods of analysis and has been used widely with large multidimensional data sets. PCA involves a mathematical procedure that transforms a number of possible correlated variables into a smaller number of uncorre...

Manufacturing produces real wealth for any country and constitutes the back bone for the service sector. The objective of any organization is to earn profit. Usually the market fixes the selling price of the manufactured components. Unless there is focus on the manufacturing strategy of reducing manufacturing cost, it is very difficult to sustain in this ever competitive world. A suitable manuf...

Manufacturing industries are under intense pressure from the increasingly competitive global marketplace. Shorter product lifecycle, time to market and diverse customer needs have challenged manufacturers to improve the efficiency and productivity of their production activities. Manufacturing systems should be able to adjust or respond quickly to adopt necessary changes in product design and pr...

existence of pressure on industries for successful competition, gives redundant importance to ability of percepting future. withal, manufacturing sector is one of the important economic pillars of each country. in line with this, the purpose of this study is presenting a model of key factors affecting the future of manufacturing in islamic republic of iran. this research is an applied research ...
