Linguistic Labels for Expressing Fuzzy Preference Relations in Fuzzy Group Decision Making

Abstract—This paper proposes improvements to pairwise group decision makers may express their preference relations in linguistic labels which are more practically implementable for solving group decision making problems. Second, it modifies the computational procedures by using fuzzy sets representation and computation, and by avoiding the use of strict representation, preserves the preference accuracy, and produce more intuitively meaningful solutions. Finally, it considers fuzzy criteria of the alternative explicitly. Solution are first derived based on each criterion, and then by using neat ordered weighted average (OWA) operator the final solution which accommodate all criteria are determined. The proposed method is verified for solving fuzzy group decision making problems, i.e.,advertising media selection cases.

Non-Numeric Method for Pairwise Fuzzy Group-Decision Analysis

In this article, we propose a non-numeric method for pairwise group-decision analysis based on fuzzy preference relations. The proposed method expresses and processes the preference relations non-numerically. The computation processes are relatively simple and fast we apply our method for selecting the most prospective new agro-industries to be implemented by multi-corporate company. Moreover, in the application we develop a procedure consisting of 4 stages: (1) a barin-storming process for alternatives and criteria identifications, (2) a pre-selection of prospective alternatives using modification of fuzzy Delphi method, (3) a pre-selection of the significant criteria by using a non-numeric pairwise fuzzy group-decision analysis. The final results are compared with results obtained by a semi-numeric method. The proposed method is suitable for group-decision making cases in which a full consensus is the most important role in selecting the alternatives.

ABSTRACT

The aim of this research was to develop an intelligent system for pasteurised milk quality assessment and prediction that could help the quality decision makers to assess and predict the pasteurised milk quality. Utilizing Expert System and Artificial Neural Network (ANN), which called SINKUAL-SP, did these analyses. The reasoning strategy used was “Forward Chaining” and the tracing method used was “Best First Search”. Certainty Factor (CF) was used for handling uncertainty.

Multi-layer neural network architecture was used. The suited activation function was Sigmoid Bipolar, which gave the best performance network with learning rate 0.005 and momentum 0.9 together with RMSE, MSE and SSE as an error criterion. The validation for neural network indicated the conformity between the output of neural network and the goal output with RMSE value of 0.0099.

The system was verified and validated by using real data collected from pasteurised milk and milk Products Company at West Java, Indonesia. In this company, the quality of fresh milk was at grade B (good), the quality of process was at grade A and the quality of packaging and storage was at grade B. This system suggested the user to always improve the quality of pasteurised milk to achieve grade A quality.

Based on the system output, quality system reconstruction was the highest priority strategy. The quality improvement system seemed to be a way to improve the process quality of pasteurised milk.

Keywords: Neural Network, expert system, pasteurised milk, quality system, soft system.
