“…Petri nets are a mathematical modelling tool that has been successfully implemented in scientific, engineering and industrial domains. Research in Petri nets falls in two categories: (i) design and analysis of a Petri net that is extended with new characteristics, e.g., soundness-preserving reduction rules for reset workflow nets [24], (ii) using existing Petri nets to problem solve, such as the implementation of Petri nets in E-commerce [5], application of fuzzy Petri nets in supervised learning environments [14], etc.…”

a b s t r a c tAlthough optical multistage interconnection networks (OMINs) promise to meet the ever growing demands of communication networks and multiprocessor systems in fast communication, they suffer from challenges such as path dependent loss and switch crosstalk. In this paper, we propose an innovative approach for reducing not only the path dependent loss but also the number of switch crosstalks in OMINs. Our approach is centered upon modelling OMINs with Petri nets and using the P-invariants method to determine the minimum number of stages m min that is sufficient to establish requested communication patterns in variable-stage OMINs. Being composed of the smallest number of stages and consequently directional couplers (or photonic switches), m min -stage OMIN employs minimal structure and, therefore, path dependent loss and also number of switch crosstalks reach the least possible values in the realization of requested communication patterns.We prove that the size of Petri nets created in this work is in polynomial dependence on the problem size which alleviates memory consumption significantly and ascertains the fact that memory capacity and performance of modern computers are indeed sufficient to run our task. We also show that the complexity results obtained in this research improve similar results reported in our previous paper. We carry out a series of computer experiments to confirm the effectiveness of the proposed approach.

“…As shown in [5,43], the main stages of the system are to: discover experience, capture and collect experience, model the experience, store the experience, evaluate the new experience, adapt the experience and transform the experience into knowledge. The management of experience processing for each process stage includes analysis, planning, organisation, support and collaboration [35,44,17], and study strategies for small-medium business information systems. One of the main benefits identified from adopting strategic information systems is the obtainment of information to manage the business more efficiently and competitively, which is, in effect, the goal of DSSs.…”

“…These methods have been successfully used in the unsupervised investigation of structure in data sets [7,8]. We have previously investigated the use of artificial neural networks [17] and Kernel Principal Component Analysis (KPCA) [20,21] to identify cases that will be used in a case-based reasoning system. In this paper, we present a novel hybrid technique.…”

a b s t r a c tSmall to medium sized companies require a business control mechanism in order to monitor their modus operandi and analyse whether they are achieving their goals. A tool for the decision support process was developed based on a multi-agent system that incorporates a case-based reasoning system and automates the business control process. The case-based reasoning system automates the organization of cases and the retrieval stage by means of a Maximum Likelihood Hebbian Learning-based method, an extension of the Principal Component Analysis which groups similar cases by automatically identifying clusters in a data set in an unsupervised mode. The multi-agent system was tested with 22 small and medium sized companies in the textile sector located in the northwest of Spain during 29 months, and the results obtained have been very satisfactory.

“…Considering diversity of coordination patterns among different departments, it is of great significance to perform modeling, analysis, verification, and optimization. However, the traditional workflow modeling and analysis techniques [1], [2], [5], [6], [11]- [13], [16], [21], [23], [25] cannot be applied directly due to its cross-department features.…”

Recently, cross-department business processes are becoming more and more complex. Different kinds of coordination patterns exist among different departments, which make modeling and analysis work more difficult. To our best knowledge, there is no formal method to give systematic modeling and verification for the cross-department processes when considering different kinds of coordination patterns among different departments. This paper proposes such a method based on Petri nets. The WF-net model extended with resource and message factors, RM_WF_Net for short, is first introduced. Then, the formal model of tasks is proposed and its coordination relations are given. Next, RM_WF_Net modeling for intradepartment processes is investigated and cross-department coordination patterns, including message interaction pattern, resource interaction pattern, task collaboration pattern, procedure abstract, service outsourcing pattern, and process activation pattern, are formally defined. The soundness of the RM_WF_Net is verified based on the reachability graph. A running case of the crossdepartment medical diagnosis business process is given to validate our proposed method.
