OPTIMAL LOT-SIZING DECISIONS WITH INTEGRATED PURCHASING, MANUFACTURING AND ASSEMBLING FOR REMANUFACTURING SYSTEMS

Tai-Sheng Su

Volume 15, Issue 3 , May and June 2018, Pages 1-26

Abstract
  This work applies fuzzy sets to the integration of purchasing, manufacturing and assembling of production planning decisions with multiple suppliers, multiple components and multiple machines in remanufacturing systems. The developed fuzzy multi-objective linear programming model (FMOLP) simultaneously ...  Read More

SOME FUNDAMENTAL RESULTS ON FUZZY CALCULUS

Atefeh Armand; Tofigh Allahviranloo; Zienab Gouyandeh

Volume 15, Issue 3 , May and June 2018, Pages 27-46

Abstract
  In this paper, we study fuzzy calculus in two main branches differential and integral.  Some rules for finding limit and $gH$-derivative of $gH$-difference, constant multiple of two fuzzy-valued functions are obtained and we also present fuzzy chain rule for calculating  $gH$-derivative of ...  Read More

INTEGRABILITY OF AN INTERVAL-VALUED MULTIFUNCTION WITH RESPECT TO AN INTERVAL-VALUED SET MULTIFUNCTION

Endre Pap; Alina Iosif; Alina Gavrilut

Volume 15, Issue 3 , May and June 2018, Pages 47-63

Abstract
  Intervals are related to the representation of uncertainty. In this sense, we introduce an integral of Gould type for an interval-valued multifunction relative to an interval-valued set multifunction, with respect to Guo and Zhang order relation. Classicaland specific properties of this ...  Read More

ON Q-BITOPOLOGICAL SPACES

Rana Noor; Arun K. Srivastava; Sheo Kumar Singh

Volume 15, Issue 3 , May and June 2018, Pages 65-77

Abstract
  We study here $T_{0}$-$Q$-bitopological spaces and sober $Q$-bitopological spaces and their relationship with two particular Sierpinski objects in the category of $Q$-bitopological spaces. The epireflective hulls of both these Sierpinski objects in the category of $Q$-bitopological spaces turn out to ...  Read More

A NEW WAY TO EXTEND FUZZY IMPLICATIONS

Yuan-Liang Han; Fu-gui Shi

Volume 15, Issue 3 , May and June 2018, Pages 79-97

Abstract
  The main purpose of this paper is to use a new way to extend fuzzy implications $I$ from a generalized sublattice $M$ to a bounded lattice $L$, such that the extended implications preserve many of the considered properties of fuzzy implications on $M$.Furthermore, as a special case, we investigate ...  Read More

ADAPTIVE FUZZY TRACKING CONTROL FOR A CLASS OF PERTURBED NONLINEARLY PARAMETERIZED SYSTEMS USING MINIMAL LEARNING PARAMETERS ALGORITHM

Hongyun Yue; Jiarong Shi; Liying Du; Xuejuan Li

Volume 15, Issue 3 , May and June 2018, Pages 99-116

Abstract
  In this paper, an adaptive fuzzy tracking control approach is proposed for a class of single-inputsingle-output (SISO) nonlinear systems in which the unknown continuous functions may be nonlinearlyparameterized. During the controller design procedure, the fuzzy logic systems (FLS) in Mamdani type are ...  Read More

FUZZY RISK ANALYSIS BASED ON A NEW METHOD FOR RANKING GENERALIZED FUZZY NUMBERS

Wen Jiang; Dong Wu; Xiang Liu; Feng Xue; Hanqing Zheng; Yehang Shou

Volume 15, Issue 3 , May and June 2018, Pages 117-139

Abstract
  Fuzzy risk analysis, as a powerful tool to address uncertain information, can provide an appropriate method for risk analysis. However, the previous fuzzy risk analysis methods still have some weaknesses. To overcome the weaknesses of existing fuzzy risk analysis methods, a novel method for ranking generalized ...  Read More

THE UNIFORM BOUNDEDNESS PRINCIPLE IN FUZZIFYING TOPOLOGICAL LINEAR SPACES

Cong-hua Yan

Volume 15, Issue 3 , May and June 2018, Pages 141-151

Abstract
  The main purpose of this study is to discuss the uniform boundednessprinciple in fuzzifying topological linear spaces. At first theconcepts of uniformly boundedness principle and fuzzy equicontinuousfamily of linear operators are proposed, then the relations betweenfuzzy equicontinuous and uniformly ...  Read More

TESTING STATISTICAL HYPOTHESES UNDER FUZZY DATA AND BASED ON A NEW SIGNED DISTANCE

M. Arefi

Volume 15, Issue 3 , May and June 2018, Pages 153-176

Abstract
  This paper deals with the problem of testing statisticalhypotheses when the available data are fuzzy. In this approach, wefirst obtain a fuzzy test statistic based on fuzzy data, and then,based on a new signed distance between fuzzy numbers, we introducea new decision rule to accept/reject the hypothesis ...  Read More
