Variability in software process models justifies tailoring them to meet the specific goals and characteristics of organizations and projects. At the present time, processes are modeled using different notations which typically do not have constructs which are appropriate for expressing process variability. To fill this gap, we have extended SPEM to vSPEM, by adding new variability constructs (s...

This paper presents a systematic methodology to develop statistical compact MOS models for advanced VLSI circuit simulation. Process variability in advanced CMOS technologies imposes a serious challenge for computer-aided VLSI circuit design. Therefore, statistical compact model has become indispensable for realistic assessment of the impact of random process variability on advanced VLSI circui...

Variability is a powerful abstraction in software engineering that allows managing product lines and business processes requiring great deals of change, customization and adaptation. In the field of Business Process Management (BPM) the increasing deployment of workflow engines having to handle an increasing number of instances has prompted for the strong need for variability techniques. The id...

Nowadays, process oriented software systems, like many business information systems, don’t exist only in one single version, but in many variants for better coverage of the target market. Until now, the corresponding customization has to be done manually, which is a timeconsuming and error-prone task, which could be realized much more efficiently by applying process family engineering technique...

Processes can be a cause of variability, a characteristic that distinguishes one product from others. Process-aware information systems (PAIS) whose implementation relies on the process specification do. For defining variability of the PAIS family analyzing variations in processes is advantageous than analyzing system features. Processes are sequential but in many cases, they are not in accorda...

A business process often shows different variations in a large organisation, due to different legal requirements in different countries, deviations in the IT infrastructure, or organisational differences. These variants are documented in separate independent process models. Management of these variants imposes various challenges. Invariant behaviour needs to be identified and redundancies among...

The Shewhart and the Bonferroni-adjustment S control charts are usually applied to monitor the standard deviation of a quality characteristic. The control limits of these charts are constructed using approximately the normal distribution in case that the standard deviation parameter is known or unknown. In this paper, we establish a new S chart that is based approximately on the normal distribu...

We study numerically how the structures of distinct networks influence the epidemic dynamics in contact process. We first find that the variability difference between homogeneous and heterogeneous networks is very narrow, although the heterogeneous structures can induce the lighter prevalence. Contrary to non-community networks, strong community structures can cause the secondary outbreak of pr...
