Volume 7, Issue 2 , Summer 2018, Pages 136-146

http://dx.doi.org/10.22105/riej.2018.143285.1051

Abstract
  The research of Fixed Point Theorems (FPTs) plays an important role in nonlinear analysis. It is of great theoretical significance and profound application value to study general abstract theory in a B-Metric-Like Space (BMLS). So, it is an important topic to study the Fixed Point Theory (FPT) in a BMLS. ...  Read More

2. Solving a new multi-objective resource constrained project scheduling problem by SAICA and compare it with DE method

A. Esmaili Dooki; p. Bolhasani; A. Alam Tabriz

Volume 7, Issue 2 , Summer 2018, Pages 147-183

http://dx.doi.org/10.22105/riej.2018.127733.1038

Abstract
  Nowadays the Resource Constrained Project Scheduling Problem (RCPSP) has triggered a substantially significant issue among scheduling problems. The purpose of RCPSP is minimizing the duration of the projects due to both limited available resources and precedence constraints. Indeed, it attempts to consume ...  Read More

3. Simultaneous optimization of quantitative and ordinal responses using Taguchi method

S. Pal; S. Gauri

Volume 7, Issue 2 , Summer 2018, Pages 184-205

http://dx.doi.org/10.22105/riej.2018.127858.1039

Abstract
  In the real world, the overall quality of a product is often represented partly by the measured values of some quantitative variables and partly by the observed values of some ordinal variables. The settings for the manufacturing processes of such products are required to be optimized considering the ...  Read More

4. Cloud manufacturing: from a concept to a way for being lean

A. Hassanzadeh; S. M. Razavi; A. Mohaghar; M. Houshmand; H. Safari

Volume 7, Issue 2 , Summer 2018, Pages 206-223

http://dx.doi.org/10.22105/riej.2018.134464.1044

Abstract
  Today, a production enterprise cannot survive without using computer-based machines. Nevertheless, not all enterprises have enough money to invest in such manufacturing resources. On the other hand, handling the resource or providing appropriate platform is not easy at all. For companies, Cloud-based ...  Read More

R. V M S S Kiran Kumar; T. Chalapathi

Volume 7, Issue 2 , Summer 2018, Pages 235-242

http://dx.doi.org/10.22105/riej.2018.133136.1042

Abstract
  Let (Zn, +) be a finite group of integers modulo n and Dn a non-empty subset of Zn containing proper devisors of n. In this paper, we have introduced the difference divisor graph Diff (Zn, Dn) associated with Zn whose vertices coincide with Zn such that two distinct vertices are adjacent if and ...  Read More

7. Ultrasonic testing for mechanical engineering domain: present and future perspective

A. Sharma; A. K. Sinha

Volume 7, Issue 2 , Summer 2018, Pages 243-253

http://dx.doi.org/10.22105/riej.2018.100730.1018

Abstract
  Ultrasonic testing uses high frequency sound waves of a range between 0.5 to 15 MHz to conduct testing. The basic principle and applications of ultrasonic testing techniques is enormous use under the domain of mechanical engineering applications. Importance of ultrasonic testing of rails, train wheels, ...  Read More
