Previously, we have put in a considerable amount of effort to separate, identify, and then classify pen gestures from any given ink trace on the digital board. Those heuristics have been proven sound and efficiently fast, but lags in coherence when it comes to administering seriously ambiguous cases when both the domains for sketches and gestures are merged. When earlier, we analysed data solel...

We study an inventory system that consists of two demand classes. The orders in the first class need to be satisfied immediately, whereas the orders in the second class are to be filled in a given demand lead–time. The two classes are also of different criticality. For this system, we propose a policy that rations the non–critical orders. Under a one-for-one replenishment policy with backorderi...

In this paper, we examine the impact of scheduling policies on batch sizing decisions in a multi-item production system. We also investigate the joint effect of scheduling policies and batch sizing decisions on production lead times. In particular, we compare the performance of a first come-first-served (FCFS) policy with a group scheduling (GS) policy and study the effect of both on the optima...

This paper treats the optimization of production batches by computer simulation in a manufacturing company producing electric and pneumatic actuators. In its introduction part the article deals about a wider context of batch production optimization. Subsequently, the paper presents a procedure for creation of a simulation model in SIMPLE ++ software environment. Based on simulation of a manufac...

Algorithms for solving agreement problems can be classified in two categories: (1) those relying on failure detectors that we call FD-based, and (2) those that rely on a Group Membership Service that we call GMS-based. The paper discusses the advantages and limitations of these two approaches, and proposes an extension to the GMS-approach that combines the advantages of both approaches, without...

Economic and cultural globalization is one of the most important processes humankind has been undergoing lately. This process is assumed to be leading the world into a wealthy society with a better life. However, the current trend of globalization is not unprecedented in human history, and has had some severe consequences in the past. By applying a quantitative analysis through a microscopic re...
