Few heuristic optimization algorithms to solve the multi-period fixed charge production-distribution problem

This paper deals with a multi-period fixed charge production-distribution problem associated with backorder and inventories. The objective is to determine the size of the shipments from each supplier and backorder and inventories at each period, so that the total cost incurred du

Some Classes of Valid Inequalities and Convex Hull Characterizations for Dynamic Fixed-Charge Problems under Nested Constraints

The authors also gratefully acknowledge the detailed comments of two anonymous referees regarding relationships with lot-sizing problems. ii Abstract This paper studies the polyhedral structure of dynamic fixed-charge problems that have nested relationships constraining the flow

A stochastic multi-stage fixed charge transportation problem: Worst-case analysis of the rolling horizon approach

We introduce the Stochastic multistage fixed charge transportation problem in which a producer has to ship an uncertain load to a customer within a deadline. At each time period, a fixed transportation price can be paid to buy a transportation capacity. If the transportation capa

CVAR-Constrained Multi-Period Power Portfolio Optimization

We consider power portfolio optimization of real and contractual assets, including derivative instruments in a multi-period setting. A model is introduced that incorporates fixed transmission rights in a three-node unidirectional network in order to evaluate the significance of t

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

Polynomial Time Algorithms for Some Multi-Level Lot-Sizing Problems with Production Capacities

We consider a model for a serial supply chain in which production, inventory, and transportation decisions are integrated, in the presence of production capacities and for different transportation cost functions. The model we study is a generalization of the traditional single-it

The Value of Flexibility in Robust Location-Transportation Problems

This article studies a multi-period capacitated fixed-charge location-transportation problem in which, while the location and capacity of each facility need to be determined immediately, the determination of final production and distribution of products can be delayed until actua
