Analysis Model

Within the context of the large-scale application of industrial robots, methods of analyzing the life-cycle cost (LCC) of industrial robot production have shown considerable developments, but there remains a lack of methods that allow for the examination of robot substitution. Taking inspiration from the symmetry philosophy in manufacturing systems engineering, this article further establishes a comparative LCC analysis model to compare the LCC of the industrial robot production with traditional production at the same time. This model introduces intangible costs (covering idle loss, efficiency loss and defect loss) to supplement the actual costs and comprehensively uses various methods for cost allocation and variable estimation to conduct total cost and the cost efficiency analysis, together with hierarchical decomposition and dynamic comparison. To demonstrate the model, an investigation of a Chinese automobile manufacturer is provided to compare the LCC of welding robot production with that of manual welding production; methods of case analysis and simulation are combined, and a thorough comparison is done with related existing works to show the validity of this framework. In accordance with this study, a simple template is developed to support the decision-making analysis of the application and cost management of industrial robots. In addition, the case analysis and simulations can provide references for enterprises in emerging markets in relation to robot substitution.

The impact of age on the distribution of wealth among U.S. sole proprietor households is analyzed using data from two national surveys in conjunction with disparity and social welfare decomposition methods. Results show higher disparity in wealth when the household is a non-farm rather than a farm sole proprietor household. The cohort with the greatest need in terms of targeted programs is the group of farm or non-farm households headed by individuals younger than 35.

This paper is an exploration of building lifespan, building characteristics, and operating expenses. The main objectives are to identify the building component lifespan, including architectural components and engineering components, to determine the pattern of building component replacement life cycle and to examine the relationship between building characteristics and facility operating expenses. The investigation was undertaken through a study of thirty-nine residential condominiums located in Bangkok. The expense data were collected through document searches and surveys with key juristic persons of each condominium. The building service life document was collected from international references and standards. The data were examined using cross-case analysis to identify the lifespan of the buildings and to identify the relationships between the condominium operating expenses and the characteristics of the buildings. It was found that the typical building replacements occur on a broad 60-year cycle that can be subdivided into several phases. Further findings indicate that a significant pattern of building component replacement shifts every two decades through the building lifespan. It was also found that the condominium operating expenses vary according to the building age and building characteristics. Direct variation, inverse variation, and joint variation from the characteristics of the condominium building can be identified. The findings add to the understanding of condominium operating expenses based on building characteristics. The study can provide a reference for consideration of building selection criteria and replacement plans, and for building budget planning based on age and building characteristics.

Agricultural Subsidy

This paper uses panel data from a sample of farm households in the northeastern China to examine the non-fungibility of different income sources. The results show the private transfer income has a high and significant impact on household consumption while agricultural subsidy and disaster relief have insignificant impacts. Empirical findings prove that the Behavioral Life Cycle Hypothesis is more practical than the Life Cycle Hypothesis. Moreover, they provide important macro policy implications as for how to stimulate farm consumption and expand domestic demand and encourage economic growth.
