In this paper, we define the notion of (dual) multi-fuzzy normedspaces and describe some properties of them. We then investigate Ulam-Hyers stability of Jensen's functional equation for mappings from linear spaces into  multi-fuzzy normed spaces. We establish an asymptotic behavior of the Jensen equation in the framework of multi-fuzzy normed spaces.

This paper presents the methodology developed for the SOLARGIS project an EU JOULE project for the integration of renewable energies in dispersed electricity production, supported in a GIS platform. The paper discusses the methodologies for the assessment of the efficiency and market of isolated system for dispersed rural electrification. The models form a mix use of probabilistic and fuzzy set...

The ability to accurately and consistently predict deformation of deep foundation pit in civil engineering is required by the designer and manager in planning and conducting construction activities. Since deformation of deep foundation pit that belongs to a multi-variable nonlinear system evolution with time-varying is vague and uncertain, it is prone to a certain degree of prediction errors. T...

cities are a focal point of energy consumption. accessibility to public services has a significant impact on the balance of public and private energy uses, which are two sectors that are directly affected by urban planning (the third is industrial). this paper establishes the relative magnitudes of service accessibility enhancement on urban energy efficiency in comparison to other factors, and ...

This paper considers the hierarchical production planning (HPP) concept to solve a production planning problem in the process industry in a fuzzy environment. The adopted fuzzy HPP consists of two levels in which a fuzzy aggregate production planning (FAPP) model is developed in the first level, and then a fuzzy disaggregate production planning (FDPP) model is developed at the second level. The...

The purpose of Multi-modal Multi-criteria Personalized Route Planning (MMPRP) is to provide an optimal route between an origin-destination pair by considering weights of effective criteria in a way this route can be a combination of public and private modes of transportation. In this paper, the fuzzy analytical hierarchy process (fuzzy AHP) and the quantifier-guided ordered weighted averaging (...

In this paper, we are going to report on the results of an exploratory piece of research about the typical front-end-related activities in 28 innovation projects carried out by 14 German and 13 Japanese companies to reduce project uncertainty. In all cases we observed a range of activities to reduce project specific risks and revealed differences in the practice of innovation management in both...

This work develops an interactive fuzzy multi-objective linear programming (i-FMOLP) method for solving the fuzzy multiobjective transportation problems with piecewise linear membership function. The proposed i-FMOLP method aims to simultaneously minimize the total distribution costs and the total delivery time with reference to fuzzy available supply and total budget at each source, and fuzzy ...

Vendor performance plays a key role in price, quality, timely delivery and service in achieving the goals of the supply chain. Given this, today's supplier performance has become a critical element in the success or failure of a company. In this study, an idealized planning model with multi-criteria decision-making approach with network analysis tool based on the expansion of fuzzy quality func...

Robot soccer is a challenging platform for multi-agent research, involving topics such as real-time image processing and control, robot path planning, obstacle avoidance and machine learning. The robot soccer game presents an uncertain and dynamic environment for cooperating agents [1][2]. Dynamic role switching and formation control are crucial for a successful game. The fuzzy logic based stra...
