The aim of the article is presenting the current state of ordered fuzzy numbers development. New model of fuzzy number was invented in 2002 to overcome drawbacks of classical (convex) fuzzy numbers. Two problems of management accounting are considered. The first relates to the management of supply and determining the optimal size of a delivery from outside, which minimize total costs, when unit costs...
Aim of the paper is to propose a new tool for a decision supporting system concerning the financial project evaluation. It is based on the determination of the internal rate of return (IRR) of a investment project in which all expenditure and anticipated incomes are vague, and described by Ordered Fuzzy Numbers (OFNs). It means that the probabilistic approach is neglected in this paper and the use...
In the present paper, authors presents a value-based comparative analysis between electrical thermal demand tracking modes of operations at the planning stage from owner's point of view. Worth of operational strategy is evaluated using maximization of net present value (NPV) of 6-bus meshed and 14-bus radial microgrids which are assessed from optimal deployment their DERs with respect to optimal locations,...
Solar PV Micro-Utility is the concept of Solar PV extension where power rather than the solar electric systems are offered to the rural poor. In this system, one will never be the owner of the system, but one can use the Solar PV system by paying a daily tariff. Several rural markets have already been electrified through Solar PV under the concept of PV Micro-Utility by Centre for Mass Education in...
