A
slacks-based
Measure of
Efficiency
for Parallel
and Series
Production
Systems
Data
envelopment
analysis
(DEA) is a
mathematical
approach for
evaluating
the efficiency
of decision
making units
(DMUs) that
convert
multiple
inputs into
multiple
outputs. In
many cases,
production
systems may
have
internal or
network
structures,
such as
series and
parallel
structures,
which are
composed of
several
processes
interacting
with each
other. |

On the Stability of Quadratic Functional Equations in Partially Ordered Banach Spaces : A Partially Ordered Fixed Point Approach
Using
partially
ordered
xed
point
method,
we
investigate
the
Hyers-
Ulam-Rassias
stability
and
superstability
of
quadratic
functional
equations
on
Banach
spaces
endowed
a
partial
order.

On Perturbation of Frames in Locally Convex Spaces
We present some Paley-Wiener type perturbation results for frames in a real (or complex) complete locally convex separable topological vector space.

On the Generalization of Some Well Known Fixed Point Theorems for Noncompatible Mappings
Various investigations have dealt with the problem that, is there a contractive definition strong enough to ensure the existence of a fixed point but the function fails to be continuous. An attempt has been made to generalize fixed point theorem of Pant, Bisht, Arora [9]. Further a fixed point theorem of Bisht and Joshi [1] finds a generalization here.

On an Openness Which is Placed Between Topology and Levine’s Openness
The goal of this present paper is to investigate new relationships of
I*g -openness. The notion of I*g-open sets was introduced by Ekici in 2011. I*g- openness is placed between topology and Levine's openness. New investigations among I*g-openness, topology and maps are introduced.
