Digital twins (DT) form part of the Industry 4.0 revolution within manufacturing and related industries. A DT is a digital model (DM) real system that features continuous automated synchronisation feedback optimisations between domains. core technology for predictive capabilities from discrete event simulation (DES). The modelling cycle developing analysing DES models significantly different compared to DM. specific introduced evolved availability specialised software tools tailored these...
The use of autonomous systems is becoming increasingly common in many fields. A significant example this the ambition to deploy unmanned aerial vehicles (UAVs) for both civil and military applications. In order such as these operate effectively, they must be capable making decisions regarding appropriate future course their mission responding changes circumstance short a time possible. will typically perform phased missions and, owing uncertain nature environments which operate, objectives...
This paper describes the integration of a sensor data stream monitoring system into proposed functional product model capable predicting availability. Such systems enable predictive maintenance to be carried out – pre-emptive that is scheduled in response imminent hardware failure and are widespread use industry. The industrial motivation for this research agreed upon availability critical element any business-to-business agreement regarding sales. important when making strategic choices FPs...
Systems often operate in phased missions where their reliability structure varies over a set of consecutive time periods, known as phases. The mission is defined the probability that all phases are completed without failure. While Binary Decision Diagram (BDD) method has been shown to be most efficient solution for measuring with non-repairable components mutually exclusive failure modes, existing BDD based methods still unable analyze large systems considerable computational expense. This...
In discrete event simulation (DES) models, stochastic behaviour is modelled by sampling random variates from probability distributions to determine outcomes. However, the distribution of outcomes for an a real system often dynamic and dependent on current state. This paper proposes use artificial neural networks (ANN) in DES models each outcome, conditional model state or input data, which can then be sampled. enables more realistic accurate modelling behaviour. An application digital twin...
The paper addresses the potential use of cloud services in Functional Products (FP) and its possible implications for availability. Further, how availability can be understood via modelling simulation is addressed. adds further specificity to literature by indicating FP constituents which are applicable adequate.
The customization of the support site configuration (including number, locations and capabilities sites where maintenance staff are based) is critical importance to functional product providers, who must provide services for products operated by their customers at different ensure that contractual guarantees availability met whilst keeping costs under control. Since contract fulfilment performance based long term, they difficult predict without modelling. This paper discusses a decision tool...
Functional Products (FP), total offers or product service systems that comprise of both Hardware (HW) and Support Services (SS) sold as an integrated offering under availability guarantee are becoming increasing popular in industry. This paper addresses, through modelling simulation the challenge faced by suppliers developing HW SS design to produce FP which meets contracted availability. A recently published framework specified how model hardware support system could be used obtain...
Functional products, consisting of hardware and support services, may be leased through performance-based contracts that provide a guarantee functional availability at fixed costs. This transfers risk from the product supplier to customer compared only sales. During development, must make design decisions influence both reliability service performance. A criterion for comparing choices accounts aversion is described, along with simulation tool can predict performance in development. Together...
A functional product (FP) comprises of an integrated package hardware and support services sold under a performance-based contract. barrier to the adoption FP is lack tools for obtaining predictions availability costs during development. previous paper by authors described simulation-driven development strategy designing that are optimised costs. This iterative involves representing design in modelling language; using software code automatically generate analyse simulation model from this...
Hydraulic drive systems are widely used in a variety of industrial applications where high torque and low speed rotational power required. The advantages include maximum from zero speed, continuously variable within wide limits, reliability insensitivity to shock loads. A system consists hydraulic circuit, electric motors, pumps, motors auxiliary components. stress on the components, hence wear failure rate, varies with output by drive. particular design can therefore vary significantly...
