Determining production rate considering costs and revenues in order to maximize profit is one of the applied problems in small and medium size factories. Mostly existing models in production planning consider production system statically and specify production rate, although the factors determining production rate include many different changes in practice. In fact, by increasing the production...

The objective of this paper is to present an empirical measure of economic welfare, hereafter called "economic position," which integrates, current money income and current net worth. We apply the resulting measure illustratively, comparing some of its results with those of the income measure. Subsequently, some of the implications of our measure are explored. The proposed measure rests on the ...

Preliminary notes This paper presents a multi-objective formulation for optimal sizing of photovoltaic resources as grid connected mode in distribution systems with the aim of maximizing net present worth of system. The proposed system in this paper includes two sources such as upstream network i.e. 63/20 kV substation and photovoltaic arrays as private sector for meeting load. Total net presen...

Assets and debts other accumulated wealth should be considered to understand one’s mental health because they influence quality of life over time. Researchers acknowledge limitations previous studies regarding health, which did not consider net worth [1]. Previous have mainly addressed Socioeconomic Status (SES) as an indicator influencing [2,3], rather than considering worth. As a result, the ...

T HE national survey of the resources of aged beneficiaries made by the Bureau of Old-Age and Survivors Insurance in 1951 included a study of their assets1 At the end of that year, it was found, threefourths of the aged beneficiaries included in the survey owned assets. Three-fifths held liquid assets, and half had nonliquid assets. Almost two-fifths reported both liquid and nonliquid assets. T...
