An integer optimization model and algorithms to support the cost-revenue study and provisory designing warehouses or other storage objects

nr 21(4)

257--269

An optimization model for the cost–revenue study at the stage of system analysis and preliminary designs of storage objects such as warehouses, containers, packs and similar objects are developed. Our assumptions motivated by warehouses design lead us to a nonlinear integer optimization problem with the only basic constraint. We present algorithmic methods for obtaining the exact solution to the general problem with emphasizing the special case when both the objective and the constraint functions are increasing. The results of the paper may be used in developing software tools intended for supporting designers.

X-maximal congruences and relevant sets for algebras

Staruch B., Staruch B.

Scientific Issues of Jan Długosz University in Częstochowa. Mathematics

2016

Vol. 21

93--104

We introduce and investigate X-maximal congruences and relevant sets for a given algebra. We describe interrelations among these concepts and atomicity of the congruence lattice and the number of atoms. We also investigate subdirect decomposition of algebras into subdirectly irreducible factors.
