the purpose of this research was to study organizational climate and faculty members' participation in decision making in physical education faculty of tehran university. for this purpose, 30 faculty members of physical education faculty were selected with census method as the statistical sample. data were collected by two questionnaires: organizational climate (?=0.92) and participation i...

The concept of “green supply chain” puts forward new requirements for the recycling management waste products. electronic products are taken as research object, and a two-stage closed-loop chain composed manufacturer, retailer, consumers is considered in this paper. By constructing Stackelberg game model, pricing strategy profit distribution under different decision modes considering asymmetric...

In this paper, we introduce a kernel for monotone data derived from the Choquet integral with its underlying fuzzy measure. While a naïve computation of this kernel has a complexity that is exponential in the number of data attributes, we propose a more efficient approach with quadratic time complexity. Kernel PCA and SVM classification are employed to illustrate characteristics and benefits of...

selecting a set of features and price for new product is one of the most important and difficult decisions for any firm. for its implementation firms require information by demand of consumers about product features,the cost of providing these features and reaction of existing competitors to new product entry. in this research, with the help of game theory, the various positions of new product ...

This article studies the optimization of pricing decisions in a supply chain with different channels under different power structure. Three different channel will be considered here; these include: the decentralized, the semi-integrated, and the integrated channel. There are two types of power balance structures for both the decentralized and the semi-integrated channels. The first type is a le...

Pricing decisions of a two-echelon supply chain with one manufacturer and duopolistic retailers in fuzzy environment are considered in this paper.Themanufacturer produces a product and sells it to the two retailers, who in turn retail it to end customers. The fuzziness is associatedwith the customers’ demand and themanufacturing cost.The purpose of this paper is to analyze the effect of two ret...

decentralisation has been described as an empty concept that lacks clarity. yet there is an enduring interest in the process of decentralisation within health systems and public services more generally. many claims about the benefits of decentralisation are not supported by evidence. it may be useful as an organising framework for analysis of health systems but in this context it lacks conceptu...

We develop the parametric weighted ordered weighted average (WOWA) operator in dynamic decision problems represented by multi-criteria decision tree, which combines the regular increasing monotonic (RIM) quantifiers with piecewise linear function. The parametric WOWA operator with piecewise linear function can be used to represent various preferences of the decision makers in the forms of risk ...
