The eL-Platform is one of ICT for realization of the environmental impact evaluation. It is a web system that is a laborsaving technology without additional cost when a company introduces and manages. It can contribute the environmental load curtailment by visualization. The word “eL” means environmental Load, eco Leading, electronic LCA, evidence Level-up and so on. In order to spread a user friendly...
In the 21st century, a shift in the principal component of the value and growth potential of companies from tangible assets to intangibles, notably brand power and technological capabilities, is occurring. Intangibles are things that generate future cash flows (claim rights) having no physical form, but do not include financial instruments. Intangibles are underlying assets that create competitive...
This paper proposes a robust-based mean-variance portfolio selection problem with random fuzzy returns using a fuzzy reasoning method, particularly a standard TS fuzzy reasoning method. Arbitrage Pricing Theory (APT) is introduced as a future return of each security, and each factor in APT is assumed to be a random fuzzy variable whose mean is derived from a fuzzy reasoning method. Furthermore, under...
This paper considers a new multiobjective tour route planning problem in order to maximize the sum of values of tourist spots to be visited and to minimize the tiredness caused by moving from place to place. The planning is formulated as a multiobjective 0–1 programming problem, and an interactive algorithm is provided to find a satisficing solution of tourists which takes account of their preferences.
This paper proposes a versatile route planning problem for sightseeing with fuzzy random variables based on constraints of required traveling times and total satisfaction of sightseeing activities. In general, traveling times among sightseeing places and the satisfactions of activities depend on weather and climate conditions. Furthermore, the satisfactions of activities are also dependent on the...
This article considers multiobjective linear programming problems (MOLPP) where random fuzzy variables are contained in objective functions and constraints. The purpose of the proposed decision making model is to optimize values at risk under the constraints using a necessity measure. An interacitve algorithm is constructed in order to obtain a satisficing solution for the decision maker from among...
This paper proposes a route planning problem for sightseeing with fuzzy random variables based on constraints of required traveling times and satisfactions of the total sightseeing activity. In general, traveling times among sightseeing places and the satisfactions of activities depend on weather and climate conditions. Tourists will like to do their favorable route planning without drastically changing...
The side-hole (defect) location in a solid material is roughly estimated from the circular wavefront of scattering waves. The measurement data recorded by a pulsed laser scanning system is employed for estimation. The preprocessing involves two steps: The peaks are extracted from the original echo signals, and then, a threshold level of 10% is applied to the peak-extracted data. The side-hole location...
With a participatory web-based environmental load estimation and labeling system, enterprises can make substantial benefit, by choosing less environmental load materials, energy use and waste disposal, leading to less environmental load labeled products. The system estimates CO2, SOx, NOx, DOD and other environmental loads, under given scenarios of selected row materials (intermediate products), energy...
In the DICE model, it simulates climate changes from macro-economic dynamics. In this paper, we assume that the temperature changes may be altered by economic or political factors, and some stochastic process provides it. Under uncertainty, we present the new approach to obtain an optimal policy on utility function based on DICE using real option approach considering the option graph.
This paper develops a new constructing approach of an appropriate membership function to integrate a given probability density function and fuzzy Shannon entropy extending the statistical theory into the heuristic method based on the human cognitive behavior and subjectivity. The proposed approach is formulated as a more general mathematical programming problem than previous approaches due to using...
