Most manufacturers use human-machine systems to produce high-quality products. Dealing with human-machine systems is very complicated since not only machines should be utilized in proper condition but also appropriate environment should be provided for human resources. Most manufacturers have a maintenance plan for machines but many of them do not have a proper work-rest schedule for human reso...

This paper presents a new mathematical model to solve cell formation problem in cellular manufacturing systems, where inter-arrival time, processing time, and machine breakdown time are probabilistic. The objective function maximizes the number of operations of each part with more arrival rate within one cell. Because a queue behind each machine; queuing theory is used to formulate the model. T...

In this paper, a mixed-integer linearized programming (MINLP) model is presented to design a group layout (GL) of a cellular manufacturing system (CMS) in a dynamic environment with considering production planning (PP) decisions. This model incorporates with an extensive coverage of important manufacturing features used in the design of CMSs. There are also some features that make the presented...

The Unified Modeling Language (UML) is widely considered as the defacto standard for the design of Object Oriented systems. This is standard has been wildly improved by the Model Driven Architecture (MDA) an other inititive of OMG to provide a complete development process for complex system. MDA promotes the use of models through the entire development process starting from a CIM for requiremen...

In this study, we developed a method for converting SysML state machine diagrams into Promela models that can be verified using the SPIN model checking tool. The Promela code generated in our approach is a sequential verification model that simplifies the verification process when used in the early stages, and also prevents state explosion in the verification process. Thus, using the sequential...

We present a model for analyzing the reliability of component-based software systems. Each software component is described as a nite state machine whose transitions have failure probabilities that re ect the unreliable execution of elementary component operations. Alternatively, we model a component as a nite state machine with an associated reliability gure that expresses the overall reliabili...

In this paper the notion of a N -finite state machine is introduced, as well as the concepts of a N -(immediate) successor, a N -exchange property and a N -subsystem are introduced. Some related properties are discussed. A condition for a N -finite state machine to satisfy the N -exchange property is established. A characterization of a N -subsystem is initiated. We prove that the isomorphism b...

We propose an approach to encode state diagrams with and-cross transitions. The notion of and-cross transitions is being rejected by researchers and practitioners in model-driven engineering community for reasons that include limited use-inpractice, unmanageable underlying complexity, and availability of alternative modeling solutions. In this paper, we show that and-cross transitions can be us...
