“…Therefore, the perturbations of delays in an SC under an uncertain time to the obsolescence of the items in a chain are studied still on the skeleton of MRP theory, using the network simulation model (NSM) approach. The results developed in natural science and technology [37][38][39][40][41][42] have been modified, which can help close the gap in meeting the requirements of the sustainable supply chain of the Basel Committee on Banking Supervision [43].…”

“…After the work of [37], the network simulation method (NSM) had already been applied successfully in several fields of engineering, such as heat transfer, electrochemical reactions, transport through membranes, inverse problems, ion transport, and others; all of these works describe non-linear transport processes. It has also been implemented to deformable solid mechanics, dry friction problems and oxidation processes [39][40][41][42].…”

Supply Chain Risk of Obsolescence at Simultaneous Robust Perturbations

The earlier planning methods of supply chains (SC) in the skeleton of the extended material requirements planning (EMRP), where the time horizon of the reverse Laplace is infinite, were not convenient to estimate the impact of the technical obsolescence of the product or technology involved, which has economic, environmental, and social consequences. Therefore, the perturbations of timing are presented until the possible obsolescence, with parallel execution of the network simulation model (NSM) to evaluate the impact of the finite lifespan on the value of the chain. The EMRP, as well as the NSM, are based on the skeleton of the material requirements planning model, where delays and their perturbations are presented transparently. Contrary to the previous studies of the net present value (NPV) in the EMRP skeleton, where the infinite horizon is assumed, the impact of shortening the horizon of activities is shown here, in order to also evaluate the risk of financing investments in the SC with a shorter lifespan of products or technology. Owing to the simultaneous appearances of the stochastic variables, the parallel execution and exchanging of data, using NSM is advised. The procedures for estimation of correction factors of the NPV and their values are given.

“…The scheme used to analyse this mechanical system is the same employed in other friction problems studied by the authors [66,67], and is at the core of a software application under development. For this reason, an exhaustive review of the state of the art is necessary, systematizing the different formulation of friction processes: Atomic Friction Microscope models [66] and macroscopic models [67]. The aim of this work is to use the rules of network simulation [1] to design a reliable and efficient network model for the stick-slip phenomenon, that can be simulated in commercial software of circuit analysis such as PSpice [68,69].…”

The study of everyday phenomena involving friction continues to maintain a high level of difficulty despite its long history. The causes of this problem lie in the different scale of the characteristics of the phenomenon, macroscopic and microscopic. Thus, very different models, valid in a narrow scope which prevents generalization, have been appearing. This survey presents the application of network simulation method to the numerical solution to the study of friction at very different scales. On the one hand, on a microscopic scale an atomic force microscope model has been studied, related to the analysis of soft surfaces at the atomic scale. Furthermore, on a macroscopic scale model related to the analysis of an industrial device, such as a brake mechanism has been studied. After presenting herein is a review of the different formulations of the friction force, the nature of the surfaces involved in the phenomenon, as well as the definition of the problems to be analyzed. The design of network models and the implementation of the initial conditions are explained. The results of the application of network models to selected problems are presented. In order to verify the reliability of the proposed models, their results are compared with the solutions obtained by other numerical methods or experimental results, one from a device developed during the preparation of this report.

Modelling of Alumina Splat Solidification on Preheated Steel Substrate Using the Network Simulation Method

A mathematical model, consisting of a set of differential equations, for the simulation of the alumina splat solidification on steel substrate is presented. The network simulation method is used to solve the problem, which provides the temperatures and the cooling rate in the splat and substrate with a high temporal and spatial resolution for different values of the preheated substrate temperature. The results of this calculation provide important information for the design of ceramic coatings. The model design is explained in depth and simulated in open source software. As expected, the temperature evolutions in several points of the splat, an important variable to know the type of phases and the effect of the manufacturing parameters on this process, coincide with the experimental results. The model is also checked by another experimental test with tin and a bigger splat, which enables the temperature to be measured during solidification. It is worth highlighting the study of the cooling rate, a fundamental parameter to determine the phase, whether amorphous, gamma or alpha. Furthermore, a sensitive study of the mesh was included in order to optimize the computational time.
