Accurate forecasting of carbon price is important and fundamental for anticipating the changing trends energy market, and, thus, to provide a valid reference establishing power industry policy. However, complicated owing nonlinear non-stationary characteristics prices. In this paper, combined model based on variational mode decomposition (VMD) spiking neural networks (SNNs) proposed. An original series firstly decomposed into relatively stable components through VMD simplify interference...
To address the complex role of equipment support resource allocation on mission reliability during warship missions, this study establishes a simulation system by using agent-based modeling to simulate task flow, structures, fault rules, and schemes. The has characteristics multielement, modular, flexible configuration easy operation. key metrics relevant different conditions, such as multistage multistate systems, number recommended allocations resources, can be calculated system. In...
In this paper, an algorithm based ant colony approach (ACA) is designed to find the optimal configuration for redundancy apportionment problem (RAP) of series-parallel multi-state system (MSS). order achieve maximum reliability under cost and performance constraints, takes advantage ACA’s combinatorial optimization, uses heuristic information about arrange components from available choice. Different traditional nominal system, universal generating function (UGF) introduced used estimate...
Abstract The test of new equipment is usually carried out in multiple batches according to the task schedule and results. Constrained by environment, cost, other factors, amount reliability data each batch relatively limited, which brings difficulties accurate estimation work. For simulation tests conducted before tests, it particularly important make full use information estimate for small sample tests. This study takes common normal-type life distribution as research object, selects...
In this paper, according to the condition B in drop test standard of JEDEC, create 3D finite element model VFBGA (very-thin-profile fine-pitch BGA) packages and impact, material solder joints can be indicated by Cowper-Symonds obtained from experiment data, taking into consideration strain rate temperature effect. Comparing with traditional elastic for balls, has better correlation experimental measurement dynamic strain, PCB center deflection. For conducting reliable analysis packaging...
As maintenance resources must be dispatched and assigned between warship equipment system, the policy is introduced to a common single-unit which repairman taking single vacation multiple vacations, respectively. This paper assumes that unit lifetime, time spent on by repairman, idle repairing all follow different Phase-type distribution, more applicable interpretive models for system reliability with vacations are built The features, such as steady-state failure frequency mean failures,...
Abstract The convenient one‐pot three‐component process excludes the use of aromatic amines.
Considering that full-time repairman is often assigned to key equipment in series, the policy of a taking single vacation introduced. This paper studies series system containing n identical components. For too stringent constraints model caused by exponential distribution and other typical distributions past studies, this assumes lifetime online components, repairman's time, idle time repair are all subject Phase-type distribution, builds more applicable interpretive for reliability, gives...
The multi-state cold standby system with two identical units has a single repair facility that provides kinds of service: preventive maintenance and corrective according to the state units, higher priority. continuous Phase-type distribution, instead exponential distribution or other typical distributions, are used described residence time in different performance operational unit, time. proposed analytic model is more suitable characterize real situation. stationary built by using matrix...
A single repair facility can provide the services of corrective maintenance and protective maintenance. For a multi-state warm standby system with priority, model is built to describe reliability satisfactorily based on PH distribution, which fit any distribution approximately. series features including stability availability, failure rate mean time between failures (MTBF) are obtained. The applicability verified in numerical application demonstrate fluctuation function as goes by.
Abstract Taking Chengdu Shuangliu(CTU) and Chongqing Jiangbei(CKG) as examples, using flight data with methods such volatility external connection degree, the difference in slots allocation between adjacent regional hub airports from time space dimensions is quantitatively depicted. It shows that overall schedule of CTU CKG similar, but during peak hours, strong passenger demand Airport makes its volume more stable, moreover enters hour one later than CTU. The morning evening peak-shaped...
