Modern çağın getirdiği teknolojik girişim işletmelerin faaliyetlerinin şeklini ve yönünü değiştirmiş dijital ekonomi ortaya çıkmıştır. E-ticaretin yoğun bir şekilde dünyanın geneline yayılması ile faaliyetlerini etkin verimli biçimde yerine getirerek varlıklarını koruma altına almaları noktasında Siber Güvelik kavramı çıkmış bu durumdan denetim faaliyetleri de kendisine düşen payı almıştır. Ser...

Water is considered a significant resource in process industries. It essential for planners to target and optimize the use of water as an external industrial operations. Such optimization problems account uncertainties related internal resources must be handled provide solutions real plants relevance. In this paper, these parametric are addressed, while targeting continuous flexible schedule ba...

This paper presents how a continuous mission verification process similar than in software engineering can be applied in early spacecraft design and Concurrent Engineering. Following the Model-based Systems Engineering paradigm, all engineers contribute to one single centralized data model of the system. The data model is enriched with some extra information to create an executable representati...

Consider a complete probability space (Ω,F ,P;F) equipped with the Þltration F = {Ft; 0 ≤ t <∞}. A stochastic process is a collection of random variables X = {Xt; 0 ≤ t <∞} where, for every t, Xt : Ω → Rd is a random variable. We assume the space Rd is equipped with the usual Borel σ-algebra B(Rd). Every Þxed ω ∈ Ω corresponds to a sample path (or, trajectory), that is, the function t 7→ Xt(ω) ...

Variation has long been an enemy to manufacturing quality and productivity. As technology increases our ability to record and process data we explore what kinds of improvements can be made with the new tools now available. The Tenneco Packaging facilities in Tomahawk, Wisconsin offer a particularly rich source of data with which to test these tools. Three good data sets have been assembled and ...

Many of the operations in the process industries are examples of discrete-event dynamic systems. Simulation of automation manufacturing systems, batch processes, start-up and shutdown procedures fall under such categories. The dynamics of these systems are characterized by the continuous process behavior intersected by discrete discontinuities. Such systems are usually described by differential...

Process Management Systems (PMSs, aka Workflow Management Systems – WfMSs) are currently more and more used as a supporting tool to coordinate the enactment of processes. In real world scenarios, the environment may change in unexpected ways so as to prevent a process from being successfully carried out. In order to cope with these anomalous situations, a PMS should automatically adapt the proc...
