facility layout problems (FLPs) are common problem in several manufacturing industries because FLPs have a great impact on production operations. Efficient manufacturing facility layout design could lead to lower manufacturing costs. Therefore, many sub problems should be addressed and considered from design stage. This research proposes a new framework for mix-model assembly line (MAL) manufac...

Moving toward a sustainable industrial activity requires an effective waste management that is applicable and efficient for all different types of industrial wastes .Waste minimization as the most acceptable option in waste management hierarchy, has a significant contribution in minimizing the solid wastes generated by manufacturing industries. The absence of appropriate policy, lack of awarene...

 Based on the recent literature of heterogeneous firms, productive firms self select themselves into foreign markets. In this framework, there is a productivity rise prior to exporting. On the other words, different export performance across firms is linked to their heterogeneity.   The main purpose of the present paper is to examine the so-called hypothesis of heterogeneous firm in Iran. For ...

Welding is an important technology especially for joining between two metals, fabricated and repairing metals products in manufacturing industries such as in automotive industries. To increase the productivity and lower cost, today the welding operation in industries introduces the welding robot. The main challenges to using welding robot is time taken to program robot path for a new job in low...

We examine the role of international trade in the reallocation of U.S. manufacturing within and across industries from 1977 to 1997. Motivated by the factor proportions framework, we introduce a new measure of industry exposure to international trade that focuses on where imports originate rather than on their overall level. Across industries, we find that plant survival and growth are negative...

This study examines the influence of factors responsible for work stress among the employees in the public sector industries in Kerala, India. The sample size of the subjects selected for the study consists of 75 Engineers, 110 Supervisors and 675 Workers in the selected manufacturing industries in kerala, India. Seven factors were identified with the existing literatures, and in consultation w...

We analyze the effect of patenting on R&D with a model linking a firm’s R&D effort with its decision to patent, recognizing that R&D and patenting affect one another and are both driven by many of the same factors. Using survey data for the U.S. manufacturing sector, we estimate the increment to the value of an innovation realized by patenting it, and then analyze the effect on R&D of changing ...
