Determining the optimal solution (OS) set of interval linear fractional programming (ILFP) models is generally an NP-hard problem. Few methods have been proposed in this field which only able to obtain value objective function. Thus, there a need for appropriate method determine OS ILFP model. In paper, we introduce three algorithms ILFP. first and second algorithms, using definition strong wea...

In this paper, we consider the bilevel linear programming problem (BLPP) where all coefficients in are interval type-2 triangular fuzzy numbers (IT2TFNs). First, convert a BLPP with IT2TFN parameters to an BLPP. next step, solve BLPPs and obtain optimal solution as IT2TFN.

Necessary optimality conditions for a nonsmooth semi-infinite interval-valued vec- tor programming problem are given in the paper by Jennane et al . ( RAIRO:OR (2020). DOI: 10.1051/ro/2020066 ). Having noticed inconsistencies their paper, Gadhi and Ichatouhane 10.1051/ro/2020107 ) made necessary corrections proposed what they considered more pertinent formulation of main Theorem. Recently, 10.1...

During normal rate programming of a pulse generator from slower to more rapid rates, intervals of output impulse suppression lasting 2 seconds plus the newly programmed interval to a maximum of 3.935 seconds are possible, and are a result of the pulse interval control system. These occur if programming falls within the susceptible window (the period between the existing interval and the new one...
