    Computer Systems Science and Engineering, Vol.33, No.5, pp. 299-308, 2018, DOI:10.32604/csse.2018.33.299
    Abstract Many Domain-Specific Modelling Languages (DSML) can not formally define their semantics, which inevitably brings many problems, such as accurate description and automatic verification of model properties. In this paper, we propose a formal description method of the structural semantics of DSML for verifying consistency of models built based on DSML. Firstly, domain indicating structural semantics of DSML is formally defined based on algebra, and then, we briefly describe our framework for formalizing DSML and verifying consistency of DSML and its models and use a classic case to illustrate our approach; based on this, we construct More >

    Computer Systems Science and Engineering, Vol.33, No.5, pp. 345-350, 2018, DOI:10.32604/csse.2018.33.345
    Abstract Petri net based Representation for Embedded Systems (PRES+) is an outstanding methodology for analysis, modeling and verification of embedded systems. State space explosion is an awful problem for PRES+ to model and analyze large complex embedded systems. In order to solve this problem, we concern with a method for expending PRES+ model by using synthesis approach. A kind of sharing synthesis operation for PRES+ is proposed in this paper. Under some conditions liveness and boundedness will be preserved by using this sharing synthesis approach. An applicable example in the form of an embedded control system More >

    Computer Systems Science and Engineering, Vol.33, No.5, pp. 379-387, 2018, DOI:10.32604/csse.2018.33.379
    Abstract Many Engineering Problems could be mathematically described by FinalValue Problem, which is the inverse problem of InitialValue Problem. Accordingly, the paper studies the final value problem in the field of ODE problems and analyses the differences and relations between initial and final value problems. The more general new concept of the endpoints-value problem which could describe both initial and final problems is proposed. Further, we extend the concept into inner-interval value problem and arbitrary value problem and point out that both endpoints-value problem and inner-interval value problem are special forms of arbitrary value problem.
