Consumer Demand with Several Linear Constraints: a Global Analysis

Supply chain network design with multi- mode demand based on acceptance degree of fuzzy constraints violated

This paper designs a mathematical model for supply chain network design problem including plants, distributors and customers in fuzzy environment. Each plant and distributor has several levels capacities. A multi-mode demand strategy is considered for the customers where only one of the modes is to be selected for each customer. Considering the acceptance degree of fuzzy constraints violated, a...

یک الگوریتم کارا برای زیر مساله‌ی ناحیه‌ اطمینان توسیع یافته با دو قید خطی

Trust region subproblem (TRS), which is the problem of minimizing a quadratic function over a ball, plays a key role in solving unconstrained nonlinear optimization problems. Though TRS is not necessarily convex, there are efficient algorithms to solve it, particularly in large scale. Recently, extensions of TRS with extra linear constraints have received attention of several researchers. It ha...

Maximum Simulated Likelihood Estimation of Consumer Demand Systems with Binding Non-Negativity Constraints

This paper proposes a maximum simulated likelihood estimator (MSLE) for demand systems with many binding non-negative constraints. Our study shows that the econo-metric implementation of the MSLE avoids high-dimensional integration. We have demonstrated the feasibility of the maximum simulated likelihood (MSL) approach for the linear expenditure system (LES) with non-negativity constraints. The...

Transport User Benefits Calculation with the “rule of a Half” for Travel Demand Models with Constraints

The importance of user benefits in transport projects assessments is well-known by transport planners and economists. Generally they have the greatest impact on the result of costbenefit analysis. It is common practice to adopt the consumer surplus measure for calculating transport user benefits. Normally the well-known “Rule of a Half”, as a practical approximation for the integral of the dema...
