Bi-level programming, a tool for modeling decentralized decisions, consists of the objective(s) of the leader at its first level and that is of the follower at the second level. Three level programming results when second level is itself a bi-level programming. By extending this idea it is possible to define multi-level programs with any number of levels. Supply chain planning problems are co...

in most of the multi-criteria decision making problems, it is important to have necessary information about relative importance of each criteria. in this group of problems, weights measure the relative importance of preferences of each criteria in comparison with the other decision making criteria. in this research, the nise method has been used for mapping mean-variance efficient frontier. nis...

Objective: In all societies, adolescents are the most vulnerable age group to addiction. Decision-making styles and attitude toward substances can play an important role in the tendency of adolescents to addiction. The aim of the current study was to investigate the role of decision-making styles and attitude toward substances in predicting the potential addiction among adolescents. Methods: I...

Let C be a threshold logic circuit computing a Boolean function MODm : {0, 1}n → {0, 1}, where n ≥ 1 and m ≥ 2. Then C outputs “0” if the number of “1”s in an input x ∈ {0, 1}n to C is a multiple of m and, otherwise, C outputs “1.” The function MOD2 is the so-called PARITY function, and MODn+1 is the OR function. Let s be the size of the circuit C, that is, C consists of s threshold gates, and ...

Microgrid implementation often lacks economic and environmental efficiencies due to sub-optimal configuration operation. The current study aims explore the optimal operational strategies for a microgrid system with maximum life cycle co-benefits. This was inspired by real optimization need Shoals Marine Laboratory, seasonal marine teaching research field station on Appledore Island, Maine. A dy...
