This paper presents a novel approach for automatic fuzzy based knowledge acquisition, which clubs supplier selection process with order allocation for dynamic supply chains to cope up with market variations. It imitates the knowledge acquisition and manipulation in a manner similar to that of decision makers who has gathered considerable knowledge and expertise in procurement domain. According to...
A wireless ad-hoc network is a collection of mobile nodes that can be deployed without the need for any centralized management infrastructure. The operation of ad-hoc networks depends on the cooperation among nodes to provide connectivity and communication routes. However, such an ideal situation may not always be achievable in practice. Some nodes may behave maliciously, resulting in degradation...
AIS (Automatic Identification System), a new type of Navaid at sea, is one of the key equipment to navigation for a ship as same as radar. But, there are many differences between them in the performance. It is very important to fuse the target information from the two sensors to get mutual benefits. The paper studies on the association arithmetic of the targets from the two sensors by adopting T_D...
In this paper, a model based on fuzzy simulation technique and hierarchical structure analysis is developed to evaluate the airlines safety. With the use of linguistic terms, subjective assessments of qualitative safety measures are represented with fuzzy variable. The relative weights of safety attributes are assessed using a pairwise comparison process. Based on the concept of optimality, fuzzy...
This paper offers an assessment of airport internal safety risk. It deals with general concept of risk and safety, describes the main causes of airport risk. A model based on fuzzy simulation technique and hierarchical structure analysis is developed to evaluate the airport internal safety risk. With the use of linguistic terms, subjective assessments of qualitative safety risk indexes are represented...
An optimization method is proposed for optimal berth system expansion planning on container terminals to improve operation performance along with the growing container quantity. This planning problem is attributed to a multi-stage decision-making problem and its solution method is divided into two parts: (1) For the decision-making sequence in the long period, dynamic programming is used to determine...
This paper presents a simulation-based study to evaluate the performance of 12 defuzzification-based approaches for solving the general fuzzy multiattribute decision-making (MADM) problem requiring cardinal ranking of decision alternatives. These approaches are generated based on six defuzzification methods in conjunction with the simple additive weighting (SAW) method and the technique for order...
