A new formulation of the optimization problem implementing European market rules for non- convex day-ahead electricity markets is presented, that avoids the use of complementarity constraints to express market equilibrium conditions, and also avoids the introduction of auxiliary binary variables...

This note settles an open problem about cut-generating functions, a concept that has its origin in the work of Gomory and Johnson from the 1970’s and has received renewed attention in recent years.

The Inventory Routing Problem (IRP) involves the distribution of one or more products from a supplier to a set of customers over a discrete planning horizon. The version treated here, the so- called Vendor Managed Inventory Routing Problem (VMIRP), is the Inventory Routing problem arising when...

Mixed-Integer optimization is a powerful tool for modeling many optimization problems arising from real-world applications. Finding a first feasible solution represents the first step for several MIP solvers. The Feasibility pump is a heuristic for finding feasible solutions to mixed integer...

Along with the entire economy, the wood industry in the Republic of Croatia also has to face strong and numerous competitors, both in the home and foreign markets. Solutions for survival and future development should be sought in market competition. Modern marketing increasingly uses branding as...

This article presents a mathematical model for jointly optimizing base stock levels for the multiple items subject to service level goals. The proposed model uses the expected demand and substitution probabilities between products as inputs and has been used to analyze the effects of demand...
