To meet the national green development trend and realize sustainable of human society, carbon emission in cold-chain distribution is costed. We plan vehicle path reasonably optimize locally for immediate demand to balance economic benefits enterprises customer satisfaction while reducing environmental pollution. minimize cost maximize satisfaction, we design an improved ant colony algorithm solve initial use insertion method demand. Taking actual data enterprise M as example, obtain optimal...
In recent years, the frequent occurrence of public health emergencies has had a significant impact on people’s life. The study emergency logistics also attracted scholars’ attention. Therefore, matching materials’ supply and demand quickly, which meets urgency satisfaction, is purpose this paper. This paper used Metabolism Grey Model (1,1) (GM (1,1)) material prediction model to predict number infections demand. Besides, we established bi-objective optimization by constructing profit loss...
Purpose: Aim at making a scheme for emergency spare parts the support problem when large equipment supply network faced with large-scale events. Design/methodology/approach : In order to analyze model, we establish security model under conditions respond in case of fuzzy demand. And end paper, adopt an improved genetic algorithms solve problem. Findings Considering from three aspects including satisfaction time, demand and cost constraints, which makes decision-making process more accord...
Based on the establishment of virtual warehouse multi-maintenance nodes, expected cost model spares requirements inventory is established to deal with emergency. Considering probability occurrence emergency as well effects between and maintenance nodes coping independently addressing lateral united are compared analyzed in circumstances huge incensement node after Finally, this two kinds numerically by an example.
This paper develops a joint strategy of condition-based maintenance and spare ordering for multistate system which is subject to competing failures due external shocks self-degradation. Failures this are hidden can be divided into two types: one-stage hard failure two-stage soft failure. The states the identified by periodic inspections replacement executed preventively or correctively in response defective failed state. When operating time reached predetermined threshold τ, ordered....
Proceed from economy theory, this paper selects the best treatment method of slopes based on minimum investment principle. In economic analysis, most important one is to find failure probability slopes. Traditional calculation doesn't consider fuzziness mechanical parameters. However, exists objectively. paper, fuzzy technique introduced and calculated using point evaluation for different slope excavation scheme. So, results accord with actual working mode better.
Gangue hill is a production in mining area which piles up by the disordered accumulation of coal waste. Because its poor stability, landslide may easily arise when meet disadvantages and accordingly cause enormous destruction geological hazard. It was found that traditional safety factor method risks failure evaluate stability gangue hills if variability fuzziness parameters are not considerded. In this paper analysis method—fuzzy point evaluation presented based on reliability theory fuzzy...
Abstract Various types of geological structures exist in the working face coal mine stope. Failure to identify structural development advance could defer timely implementation reasonable management measures, which may eventually affect production safety and connectivity. As a matter fact, fine detection interpretation problems in-seam seismic wave caused by different anomalies such as faults collapse columns can simultaneously mining. In view these problems, forward modeling research...
Abstract The mine transient electromagnetic method and the direct current were used to detect abundant water at 1,144 m ahead of track roadway on 9101 working face in Chaoyang Coal Mine. Low-resistance abnormal areas indicated by both methods analyzed comprehensively for early warning hazards. results showed that two low-resistance existence a area was method. Both ahead, delineating possible illegal mining old kilns which verified drilling. can indicate direction case shows combination...
