Process mining techniques enable the analysis of processes using event data. For structured processes without too many variations, it is possible to show a relative simple model and project performance and conformance information on it. However, if there are multiple classes of cases exhibiting markedly different behaviors, then the overall process will be too complex to interpret. Moreover, it...

The formalization of process definitions has been an invaluable aid in many domains. However, noticeable variations in processes start to emerge as precise details are added to process definitions. While each such variation gives rise to a different process, these processes might more usefully be considered as variants of each other, rather than completely different processes. This paper propos...

In the present work, we consider spectrally positive Lévy processes (Xt, t ≥ 0) not drifting to +∞ and we are interested in conditioning these processes to reach arbitrarily large heights (in the sense of the height process associated with X) before hitting 0. This way we obtain a new conditioning of Lévy processes to stay positive. The (honest) law Px of this conditioned process is defined as ...

This paper examines the implications of the production transformation asymmetry on prices of the commodity relative to the prices of its derivative products. When the production transformation process of a harvested good is irreversible, the price linkage between the harvested good and its derivatives breaks. This happens in the case where the supply of the good declines significantly and when ...

The SEI’s Capability Maturity Model for Software has popularized the notion of measuring the software process maturity of organizations. ISO’s SPICE project is currently creating a set of international standards for software process management that harmonize existing approaches. One of the objectives is to create a way of measuring process capability, while not using a specific approach such as...

(e. g. the Traveling Salesperson Problem), we made the same experiments and enlarged each message to 10000 bytes by sending some additional dummy messages. Since the number of migrated messages for our algorithm is very low in comparison to randomized load balancing methods, we could achieve nearly the same results on all De Bruijn networks. For example, we achieved a speedup of 61.46 on a 64 p...

Most business processes in real life are not strictly ruled by the information systems that support them. This behavior is reflected in the traces stored by information systems. It is useful to diagnose in early stages of business process analysis. Process diagnostics is part of the process mining and it encompasses process performance analysis, anomaly detection, and inspection of interesting ...

260 What is the minimum amount of carbon dioxide that a process can produce? This may seem like a trivial question but it is not a question usually asked when processes are being designed. In many cases, there is a lack of a quantitative description of what is the highest efficiency, least amount of energy, or lowest amount of carbon dioxide that can be achieved for a particular process, i.e., ...

In this paper, an integrated process monitoring and diagnostic Engineering knowledge is represented based on the hierarchical " " system the process navigator, is developed for automotive body concept proposed for the auto body representation (Ceglarek et. al., 1994). In this paper, the hierarchical group concept is assembly processes. The objective of the process navigator is to extended by de...
