It can be difficult estimating all of the cost components that are attributed to a machined part. This problem is more pronounced when a factory uses group technology manufacturing cells as opposed to a functional or process layout of a job shop. This paper describes how activity-based costing (ABC) concepts can be integrated into a discreteevent simulation model of a U-shaped manufacturing cel...
Energy is one of the main factors of production in various economic activities. The development of economic activities in different countries and regions leads to higher energy consumption and production of environmental pollutants. This study uses an Input-Output model based on the CHARM RAS method to investigate the role of economic activities in Khorasan Razavi province in the production of...
The sudden drop in crude oil prices during the Coronavirus pandemic, once again rises the concern about oil countries future if oil diminishes. This paper uses a multi-country general equilibrium model to project the effects of eliminating oil revenues. The model consists of 5 oil exporters (i.e., Iran, Kuwait, Saudi Arabia, Kazakhstan and Russia), 25 non-oil exporting countries, and the rest o...
Using a Bass Diffusion model we investigate the effect of cannibalization within a hybrid manufacturing /remanufacturing/refurbishing system. The hybrid system consists of newly manufactured products, remanufactured products, and refurbished products. The impact of the collection, remanufacturing, and refurbishing ratios on economic performance are simulated and analyzed. We numerically calcula...
In the past three decades, Chinese economy has been arresting the worldwide attention for its doubledigit growth rate. Playing a leading part in general economic development, Chinese manufacturing has been contributing a substantial portion in the total GDP growth. However, a national key project, the Research of China National Manufacturing Strategy, has found in the last several years that Ch...
This paper reveals the experiences of the application of a software tool that combines discrete event simulation (DES), material flow analysis (MFA) and life cycle assessment (LCA) in a single simulation model. This view focuses not only on economic optimization but also on material flow analysis opening the door to sustainable production in the future. Thus, the software unifies the economic a...
The increasing concerns about the environment and the depletion of natural resources are the main drivers for the growing interest in sustainability. Manufacturing operations are frequently considered to have an adverse effect on the environment. Hence, the sustainable operation of manufacturing facilities is a vital practice to ensure sustainability. The aim of this paper is to find the optimu...
Economic development usually leads to increased energy consumption, which in turn will result in an increase in carbon emissions. To break the relationship between economic development and carbon emissions, scholars have turned their attention to the phenomenon of decoupling. In this paper, we studied the decoupling relationship between carbon emissions and economic growth of the equipment manu...
regarding the importance and high proportion of iranian manufacturing industries' export in nonoil export basket, and their impact on economic growth, it is essential that effective factors on the manufacturing industries' export be investigated. this paper investigates the impact of human capital on the export of iranian industries, using a panel data set of 2-digit isic manufacturing industri...
Traditional economic manufacturing quantity (EMQ) model addressed that the perfect production for product. However, there possibly exists the defective product in the manufacturing process. Hence, it is necessary to include the quality cost in the EMQ model. In this paper, we propose a modified EMQ model with quality loss and inventory cost. By solving the modified EMQ model, we can obtain the ...
