In the last decade, theory of constraint application in project management lead to make a new approach for project scheduling and control as a critical chain. In this paper, a multi-objective optimization model for multi-project scheduling on critical chain is investigated. The objectives include time, cost and quality. In order to solve the problem, a Simulated Annealing algorithm is developed...

wastewater planning management is a complex problem involving agricultural, rural and industrial interests. in countries facing rapid population growth, identifying methods that can allow them to take good decisions among several competitive alternatives is of utmost importance. the purpose of this paper is to present a methodology for a wastewater planning management system using a multi-c...

Background: Teriparatide is a new agent serves as a treatment of choice for severe post-menopausal osteoporotic patients who are at a high risk of fracture or have failed or been intolerant of previous osteoporosis therapy. The objective of this study is estimating the cost-utility of Teriparatide compared with no treatment from health system perspective in Iran. Method: A microsimulation...

ABSTRACT- According to article 44 of the I.R. of Iran Constitution, the Iranian economy consists of three sectors; the state, the cooperative, and the private sectors. The aim of this study was to present a hierarchy of criteria for selecting the best economic sector for agricultural development. Analytic Hierarchy Process (AHP) was used to calculate the relative importance of either criteria o...

One-period models, which were the subject of Lecture 1, are of limited usefulness in the pricing and hedging of derivative securities. In real-world markets, trading takes place in continuous time; moreover, perfect hedging of many derivative securities requires continuous rebalancing of portfolios, as we shall see. Nevertheless, useful numerical approximations can often be gotten by using disc...

Citation analysis can go beyond its present preoccupations and explore new areas if it follows several rules of research design-some of them known and generally accepted, others specific to this discipline: (a) a rigorous definition of the research objectives is essential in deciding on its design, including the selection and definition of variables and the measurement of their effects; (b) the...

We propose a unifying framework for generalising the Wasserstein-1 metric to a discrepancy measure between nonnegative measures of different mass. This generalization inherits the convexity and computational efficiency from the Wasserstein-1 metric, and it includes several previous approaches from the literature as special cases. For various specific instances of the generalized Wasserstein-1 m...
