The problem of knowledge-based multiattribute classification with nonorderable classes is considered within the Verbal Decision Analysis (VDA) paradigm. Two VDA-based methods for such problem solving — NORClass and STEPCLASS — are outlined. The STEPCLASS method is initially designed for the...

Set-valued information systems are generalized models of single-valued information systems. Its semantic interpretation can be classified into two categories: disjunctive and conjunctive. We focus on the former in this paper. By introducing four types of dominance relations to the disjunctive...

The energy and material processing industries are traditionally characterized by very large-scale physical capital that is custom-built with long lead times and long lifetimes. However, recent technological advancement in low-cost automation has made possible the parallel operation of large...

In this article the results of a comprehensive empirical study of 1,200 Polish online stores are presented. It was focused on elements that affect the lead time: information about the availability of goods, about the exact stocks and about the declared delivery time. The significant differences...

The purpose of the study was to investigate the role of effective buyer supplier relationship on supply chain performance in Kenya. The study objectives were to identify how lead time, quality, cost and employee morale affects effective buyer supplier relationship on supply chain performance in...

We develop a deterministic optimization model that incorporates carbon emissions in a multi-echelon production-inventory model with lead time constraints. We impose that each customer order must be delivered within the due date fixed by the customer. The quantity that cannot be delivered on time...
