Introduse and Need Assessment of Regional Aircrafts by Software and Modeling

An analysis was conducted to examine the market visibility of small aircraft as a transportation mode in competition with automobile and scheduled commercial air travel by estimating the pool of users that would potentially switch on-demand air travel due to cost/time saving. These new aircraft greatly increase the practicality of regional aircraft as a transportation mode that can avoid the co...

Modeling and Analyzing Incremental Quantity Discounts in Transportation Costs for a Joint Economic Lot Sizing Problem

Joint economic lot sizing (JELS) addresses integrated inventory models in a supply chain. Most of the studies in this field either do not consider the role of the transportation cost in their analysis or consider transportation cost as a fixed part of the ordering costs. In this article, a model is developed to analyze an incremental quantity discount in transportation cost. Appropriate equatio...

Mathematical Modeling for a Flexible Manufacturing Scheduling Problem in an Intelligent Transportation System

This paper presents a new mathematical model for a production system through a scheduling problem considering a material handling system as an intelligent transportation system by automated guided vehicles (AGVs). The traditional systems cannot respond to the changes and customer’s demands and for this reason, a flexible production system is used. Therefore, for this purpose, automated transpor...

Modeling of solid waste collection and transportation in metropolitan areas using WAGS model: implication of CO2 emission and external costs

Annually more than 80% of the overall budget of the uran solid waste management system in Iran is allotted to collection and transportation of the solid wastes. The main objective of the current study is to evaluate the external costs associated with solid waste collection, transfer, and transportation in Tehran for the period of 2018 to 2032 based on the current situation. Waste guidance syste...

Modeling a Multi-period Transportation System for Supplier Selection and Orders Allocation Problem (case study: Parchsaz company)

The combination of transportation costs is very important in supplier decisions. In these days economic and productive firms in order to gain a competitive advantage or competitive advantage with the aim of gaining more market share in terms of controlling the cost of raw materials that directly and indirectly constitutes a major part of the cost of the product They are on their agenda. Hence, ...
