۱۹۳۵ نتیجهDuality in Multi-Commodity Market Computations
In search for general equilibrium in multi-commodity markets, price-oriented schemes are normally used. That is, a set of prices (one price for each commodity) is updated until supply meets demand for each commodity. It is well known that in a two-commodity market resource-orient
On Resource-Oriented Multi-Commodity Market Computations
In search for general equilibrium in multi-commoditymarkets, price-oriented schemes are normally used. That is, a set of prices (one price for each commodity) is updated until supply meets demand for each commodity. In some cases such an approach is very inef cient, and a resourc
Augmenting flows for the consistent migration of multi-commodity single-destination flows in SDNs
Updating network flows in a real-world setting is a nascent research area, especially with the recent rise of Software Defined Networks. While augmenting s-t flows of a single commodity is a well-understood concept, we study updating flows in a multi-commodity setting: Given a di
A kinematic wave theory of multi-commodity network traffic flow
A systematic understanding of traffic dynamics on road networks is crucial for many transportation studies and can help to develop more efficient ramp metering, evacuation, signal control, and other management and control strategies. In this study, we present a theory of multi-co
Decentralized Multi-Commodity and Multi-Period Mathematical Model for Disaster Relief Goods Location and Distribution using HACO-VNS Hybrid Algorithm
Logistics makes up one of the significant parts of humanitarian organizations. Regarding the natural disasters’ increasing growth, coordination and cooperation in the logistics sector get more and more critical in order to minimize costs and enhance relief effectiveness. Thus, th
Developing multi-objective mathematical model of sustainable multi-commodity, multi-level closed-loop supply chain network considering disruption risk under uncertainty
Nowadays, the issue of the difference in core competencies has turned into the main factor of competition in the market in most organizations. In line with their operational area, the companies make decisions to further strengthen some of their capabilities, capacities, and speci
An MILP approach to Multi-location, Multi-Period Equipment Selection for Surface Mining with Case Studies
In the surface mining industry, the Equipment Selection Problem involves choosing an appropriate fleet of trucks and loaders such that the long-term mine plan can be satisfied. An important characteristic for multi-location (multi-location and multi-dumpsite) mines is that the un
Routing multi-class traffic flows in the plane
We study a class of multi-commodity flow problems in geometric domains: For a given planar domain P populated with obstacles (holes) of K ≥ 2 types, compute a set of thick paths from a “source” edge of P to a “sink” edge of P for vehicles of K distinct classes. Each class k of ve
Lagrangean Heuristic for a Multi-Plant Lot-Sizing Problem with Transfer and Storage Capacities
The paper addresses a multi-item, multi-plant lot-sizing problem with transfer costs and capacity constraints. The problem is reformulated according to a multi-commodity flow formalism, and decomposed, through Lagrangean relaxation, into a master facility location problem and a s
On Stability and Convergence of Multi-Commodity Networks and Services
The rise of distributed services and user-driven networking concepts in recent years poses the critical question of stability. Can a system operating under non-cooperation and self-interest converge to a stable state? and how fast? The answers to these questions readily lend them
