Decision Support Model to Select Cushioning Material for Dynamics Hazards During Transportation

Aiding Route Decision for Hazardous Material Transportation

This research attempts to build a framework for determination of optimal routes for hazardous material transportation. Previous works have suggested incorporation of many conflicting objectives in the analysis, such as travel cost, population exposure, environmental risk or security concerns. Multiplying the number of objectives leads to complex shortest path problems that often have several ef...

A Decision Support System (DSS) to Select the Premier Fuel to Develop in the Value Chain of Natural Gas

A value chain is a series of events that takes a raw material and with each step adds value to it. Global interest in the application of natural gas (NG) in production and transportation has grown dramatically, representing a long-term, low-cost, domestic, and secure alternative to petroleum-based fuels. Many technological solutions are currently considered on the market or in development, whic...

A decision model to select facial tissue raw material: A case from Iran

The objective of this research is to design an approach for selecting appropriate raw materials for facial tissues in Iran. There are three possibilities to maintain raw materials: (1) imported virgin pulp; (2) bagasse (sugar cane residue) plus some imported raw materials; and (3) recycled paper plus some imported raw materials. Owing to the shortage of raw materials as well as the high rate of...

Multi-perspective Decision Support System for Hierarchical Bus Transportation Network Design‎: ‎Tehran Case Study

In this paper, a multi-perspective decision support system (MP-DSS)‎ ‎to design hierarchical public transportation network is developed‎. ‎Since this problem depends on different perspectives‎, ‎MP-DSS consists of two sub-systems with macro and micro sub-systems based on travel information‎, ‎land use and expert knowledge‎. ‎In the micro sub-system‎, ‎two sub-modules are developed considering o...
