![]() ![]() The two main competitors of TimeNet software are Agile CRM and Samepage.Īgile CRM software is a cloud-based customer relationship management (CRM) platform whereas TimeNet software is an on-premise time tracking & project management solution.Īgile CRM is suitable for small and medium-sized organizations, but in contrast, TimeNet is suitable for independent freelancers, small as well as midsize teams in various industries. In the full version of this paper, we briefly discuss an application to unmanned aerial vehicle (UAV) swarms, which has been implemented on top of a prototype of our theory for both simulation models and real world deployments. To uniformly capture dataflow, controlflow, and workflow, we use a subclass of Petri nets as an intuitive high-level model, which is translated into a weaker model - namely, a new variant of Petri nets that does not make any atomicity assumptions but instead uses a partial order to ensure eventual consistency. In this paper we present the theory of a new distributed computing model for such systems as a first step toward a model-based design methodology for FCPS. ![]() Fractionated cyber-physical systems (FCPS) are an interesting subclass of NCPS where the redundancy and diversity of many unreliable and potentially heterogeneous networked components is exploited to improve scalability, reliability, and verifiability of the overall system. Data-driven computation has also been an important paradigm in sensor networks and embedded systems, which have evolved into a larger research effort on networked cyber-physical systems (NCPS), that can sense and affect their environment. ![]() With the ongoing trend to parallelize computations for scalability, better performance, and reliability, distributed dataflow models are attracting interest at all design levels, ranging from processorarchitectures to local- and wide-area computing clusters in the cloud. Rare-event simulation (RES), variance reduction technique (VRT), partition of the region (PoR), simple PoR, recursive PoR, advanced PoR. To evaluate the efficiency of the proposed technique and its variants, the comparative simulation results of some illustrative examples using stochastic activity network (SANs) will be presented. Advanced PoR, is a more general technique that integrates the partition of the region method and the importance sampling technique. Simple and recursive PoR are powerful techniques, which have some important features such as bounded relative error (BRE) however, they are restricted to some specific models. Three variants of the proposed technique will be introduced: simple PoR, recursive PoR and advanced PoR. In this paper, partition of the region (PoR) method is used as a variance reduction technique (VRT) in a new RES technique for usage with a wide range of modelling and simulation languages. However, these techniques not only have some limitations, but also are not general and easy-to-use. The existing rare-event simulation (RES) techniques, such as importance sampling (IS), splitting and RESTART, have been used for rare-event simulation so far. Rare events are an important limitation of discrete-event simulation in some areas of applications. The suggested model is tested using numerical examples and simulated using TimeNet tool. Sensitivity analysis is carried out to illustrate the effect of the input parameters on the selected performance measures. The obtained results provide an estimate of machine, robot, and operator utilization and production rates for the considered flexible manufacturing cell. A generalized stochastic Petri net model is constructed for a single-machine and three-machine flexible manufacturing cells, after which the suggested generalized stochastic Petri net model can be generalized to a flexible manufacturing cell with n machines. When a machine is in failure, a repair action is taken by the flexible manufacturing cell operator. The machines are subject to failure after a certain time due to tool wear or resetting. Then, the robot loads parts onto the machines, which perform similar machining processes. The conveyor transfers similar workpieces to the robot areas. The analyzed flexible manufacturing cell consists of one or more machine(s), a single conveyor, and a single robot. In this article, a generalized stochastic Petri net model is developed to analyze the performance of a multimachine flexible manufacturing cell. ![]()
