land use planning is the main core of urban planning and one of the main components of an urban system. this element has close relation with transportation system of the city, so if their interaction becomes insufficient, deterioration and chaos would have an adverse impact on the urban system and would cause serious environmental issues. the integrated land use-transportation models seem to b...

â â â  â â â â â  the aim of this paper is to simulate the effects of some macroeconomic policy tools on production and inflation of iran by the current worldwide financial and real crisis. the theoretical framework of the analysis is based on the so-called ‘imf/world bank integrated model’ which is the synthesis (a merger) of the basic monetary approach of the balance of payments used at t...

In this paper, we propose a new model for designing integrated forward/reverse logistics based on pricing policy in direct and indirect sales channel. The proposed model includes producers, disposal center, distributers and final customers. We assumed that the location of final customers is fixed. First, a deterministic mixed integer linear programming model is developed for integrated logistic...

Production planning and maintenance are two important problems in manufacturing systems. Despite the relationship exists between these two problems due to sudden failures and production capacity occupied by maintenance activities, each of these problems planned separately and as a result program and model efficiencies reduce in the real world. The aim of integrated production and maintena...

Modern business environment focuses on improving the operational efficiency of supplier, retailer and customers through integrating their inventory. Although a smoothly running integrated inventory system is ideal, the reality is to deal with imperfectness in transportation. In actual production environments, inventory items are not perfect and defectiveness occurs in random process.  In this p...
