Analysis of order review/release problems in production systems
Cataloged from PDF version of article.Order Review/Release (ORR) activities have mostly been ignored in past job shop research. In most previous studies,
arriving jobs are immediately released to the shop #oor without considering any information about the system or job
characteristics. In practice however, these jobs are often "rst collected in a pool and then released to the system according
to a speci"c criterion. Although practitioners often observe the bene"ts of ORR, researchers have found limited support
for the use of these input reglation policies. One objective of this paper is to examine this research paradox in
a capacitated system. We also o!er a new classi"cation framework for existing research work. Finally, for the "rst time in
this paper, both periodic and continuous ORR methods are compared simultaneously under various experimental
conditions against di!erent performance measures. The results of simulation experiments and statistical tests are also
presented in the paper
A load-based and due-date-oriented approach to order review/release in job shops
In this paper, a new order review/release (ORR) method is proposed for shop floor control systems. The proposed method utilizes both job due date and shop load information to improve the effectiveness of the ORR function in production systems. The performance of the new method is compared to those of a few well-known ORR methods under four experimental conditions. The results of extensive simulation experiments indicate that the proposed method is superior with respect to the mean absolute deviation measure. In general, it is also better than existing methods for the other performance measures. Furthermore, we show that the proposed method is more robust to variations in system load and processing times than the other ORR methods examined
Fixed point results for generalized cyclic contraction mappings in partial metric spaces
Rus (Approx. Convexity 3:171–178, 2005) introduced the concept of cyclic contraction
mapping. P˘acurar and Rus (Nonlinear Anal. 72:1181–1187, 2010) proved some fixed
point results for cyclic φ-contraction mappings on a metric space. Karapinar (Appl. Math.
Lett. 24:822–825, 2011) obtained a unique fixed point of cyclic weak φ- contraction mappings
and studied well-posedness problem for such mappings. On the other hand, Matthews
(Ann. New York Acad. Sci. 728:183–197, 1994) introduced the concept of a partial metric
as a part of the study of denotational semantics of dataflow networks. He gave a modified
version of the Banach contraction principle, more suitable in this context. In this paper, we
initiate the study of fixed points of generalized cyclic contraction in the framework of partial
metric spaces. We also present some examples to validate our results.S.

Fixed points for cyclic R-contractions and solution of nonlinear Volterra integro-differential equations
In this paper, we introduce the notion of cyclic R-contraction mapping and then study
the existence of fixed points for such mappings in the framework of metric spaces.
Examples and application are presented to support the main result. Our result unify,
complement, and generalize various comparable results in the existing literature.http://link.springer.com/journal/11784am2016Mathematics and Applied Mathematic

Why do some followers remain silent in response to abusive supervision? A system justification perspective
Copyright © 2023 The Authors. This study investigates how the system justification motive manifests in employees’ voice/silence behavior at the workplace. It also explores the moderating effects of system justification on the linkage between abusive supervision and voice/silence behavior for blue- and white-collar employees. The field study generated responses from 905 employees in Turkey. Multi-group analysis reveals that the moderating effect of system justification motives varies by occupational class. In particular, the impact of abusive supervision on silence becomes more salient when white-collar employees endorse higher system justification motives. However, in the blue-collar sample, the absence of a moderating effect could be attributed to the strong main effect of system justification motives. The current study adds to the extant literature by applying a system justification perspective to voice and silence behavior by collar differences at work. It also provides important implications for managers in dealing with workplace mistreatment affecting all occupational groups, mainly when blue-collar employee silence is endemic and regulatory policies are inadequate
