Consider the problem of allocating objects to agents and how much they should pay. Each agent has a preference relation over pairs of a set of objects and a payment. Preferences are not necessarily quasi-linear. Non-quasi-linear preferences describe environments where payments influence agents’ abilities to utilize objects. This paper is to investigate the possibility of designing efficient and...

We propose an oligopoly game where quantity setting firms have incomplete information about the demand function. At each time step they solve a profit maximization problem assuming a linear demand function and ignoring the effects of the competitors’ outputs. Despite such a rough approximation, that we call “Local Monopolistic Approximation” (LMA), the repeated game may converge at a Nash equil...

the main goal of this study was to investigate the way of affecting of water in production of cucumber. from aspect of econometrics, mutual relationships of production function and expenses have been analyzed in which translog cost function has been used. this function has been estimated using the conditional input demand functions, the shefard theorem, chemical fertilizer, animal fertilizer, l...

This study focused on the advanced oxidation of the hetero bi-functional reactive dye Sumifix Supra Yellow 3RF (CI Reactive Yellow 145) using dark Fenton and photo-Fenton conditions in a lab-scale experiment. A 2(3) factorial design was used to evaluate the effects of the three key factors: temperature, Fe(II) and H2O2 concentrations, for a dye concentration of 250 mg L(-1) with chemical oxygen...

To safeguard analytical tractability and the concavity of objective functions, the vast majority of models belonging to oligopoly theory relies on the restrictive assumption of linear demand functions. Here we lay out the analytical solution of a di erential Cournot game with hyperbolic inverse demand, where rms accumulate capacity over time à la Ramsey. The subgame perfect equilibrium is chara...

The transport road network design problem examines the expansion or addition of link capacity in a network. While this topic has a rich history in the literature, it becomes particularly challenging when complexities such as dynamics or inherent network uncertainties are considered. This work introduces a dynamic, system optimal flows approach which includes demand uncertainty and for which a g...

In this paper we consider multi–inventory systems in presence of uncertain demand. We assume that i) demand is unknown but bounded in an assigned compact set and ii) the control inputs (controlled flows) are subject to assigned constraints. Given a long–term average demand, we select a nominal flow that feeds such a demand. In this context, we are interested in a control strategy that meets at ...

A good model of the relationship between the market demand and prices plays a very important role in economic decision-making. Linear demand functions have been widely used in Economics. They work well when there is a single market segment and only a single price is considered (SSSP). However, difficulties have been encountered when we attempted to design a model for multi-market segments and m...

this paper proposes a new mathematical model for the integrated procurement-production-distribution problem of a fuzzy mixed integer linear programming (fmilp) type. considering the uncertainty in real problems, a number of parameters such as demand, capacity, and cost where their values are not available or known precisely, have been considered as trapezoidal fuzzy numbers. to solve fuzzy mixe...
