AN EXTENSION OF TOPSIS FOR FUZZY MCDM BASED ON VAGUE SET THEORY

1.Introduction The multicriteria decision-making problem(Kickert1978)is a kind of problem that all the alternatives in the choice set can be evaluated according to a number of criteria.A MCDM problem can be concisely expressed in matrix format as C1C2C n11112122122212nnm m m mnA x x xMA x x xA x x x=W={w1,w2,,wn}where A1,A2,,Am are possible alternatives among which decision-makers have to choose,C1,C2,,C n are the criteria with which alternative performance are measured,xi j is the rati…     

VIEWING URBAN DISRUPTIONS FROM A DECISION INFORMATICS PERSPECTIVE

1. Introduction Urban infrastructures are the focus of terrorist acts because, quite simply, they produce the most visible impact, if not casualties. From the September 11, 2001 (i.e., “9/11”) attack on New York City’s World Trade Center to the more recent March 11, 2004, attack on Madrid’s commuter trains, it is obvious that urban centers are indeed vulnerable to such hideous acts. A systemic or holistic approach to securing the infrastructure systems that underpin an urban center isr…     

MODELING COMMERCIAL PROCESSES AND CUSTOMER BEHAVIORS TO ESTIMATE THE DIFFUSION RATE OF NEW PRODUCTS

1. Introduction In his famous seminal book (Rogers 1962), Rogers introduced and popularized a generic framework for analyzing and describing how the mechanism of diffusion of innovations works inside a given population. In this general approach, “innovation” can of course be understood in a large way: it may indeed referto various contexts such as the learning of a new practice, the use of a new tool, the launch of a new product, etc. The strength of Rogers' point of view comes from the fac…     

AGENT-BASED SIMULATION FOR KANSEI ENGINEERING： TESTING A FUZZY LINEAR QUANTIFICATION METHOD IN AN ARTIFICIAL WORLD

This paper argues that agent-based simulation can be used as a way for testing Kansei Engineering methods which deal with the human reaction from sensory to mental state, that is, sensitivity, sense, sensibility, feeling, esthetics, emotion affection and intuition. A new fuzzy linear quantification method is tested in an artificial world by agent-based modeling and simulations, and the performance of the fuzzy linear method is compared with that of a genetic algorithm. The simulations can expand people＇s imagination and enhance people＇s intuition that the new fuzzy linear quantification method is effective.     

Temporal Memory Reinforcement Learning for the Autonomous Micro-mobile Robot Based-behavior

This paper presents temporal memory reinforcement learning for the autonomous micro-mobile robot based-behavior. Human being has a memory oblivion process, i.e. the earlier to memorize, the earlier to forget, only the repeated thing can be remembered firmly. Enlightening forms this, and the robot need not memorize all the past states, at the same time economizes the EMS memory space, which is not enough in the MPU of our AMRobot. The proposed algorithm is an extension of the Q-learning, which is an incremental reinforcement learning method. The results of simulation have shown that the algorithm is va|id.     

纳米铝在炸药中的分散性和成型性

为了研究纳米铝在炸药中的分散性和成型性,利用不同溶剂对纳米铝进行了分散;利用超声波分散法、高速剪切混合法、叶片式搅拌混合、分散加高速分散机混合对黑索金/铝(RDX/Al)体系进行分散;采用熔融混合造粒工艺研究了不同纳米铝粉含量的成型性,采用直接混合造粒工艺研究了不同纳米铝粉含量对RDX/Al体系成型性,结果表明:乙酸乙酯的分散效果最好;超声分散可以提高纳米铝粉的分散均匀性;采用的三种工艺可以达到相同的分散效果;微米铝和纳米铝在三硝基甲苯(TNT)中的成型性基本无变化;在RDX/Al体系的压装炸药中,含纳米铝的炸药成型性较含微米铝的炸药差;含纳米铝炸药的密度随铝粉含量增加呈现非线性变化,而纳米铝和微米铝级配的炸药密度随铝粉含量增加呈现线性增加.
