In this study, a fuzzy bi-level chance constraint programming (FBCP) model is developed for urban ecological management in Xiamen, China. FBCP has advantages balancing trade-offs between multiple decision makers and can address stochastic uncertainty ecosystem management. It also reflect the impact of different violation risk levels emission reduction measures on system benefit, service value, ...

For power retailers in a smart grid, it is necessary to design an economic dispatch method maintain balance between supply and demand on the sale side as well obtain better benefits. This study concentrates of dominant retailer regional market. The considered be equipped with generator resources such distributed photovoltaics (PV), wind turbines (WT), microturbines (MT). As one cannot exactly p...

Abstract A significant part of highway and street congestion is produced by work zones. Depending on the type construction and/or rehabilitation activity, capacity could be significantly decreased, or completely closed. The zone generates traffic delays in where maintenance performed. Additionally, additional neighboring streets, since many drivers change their routes. There are numerous possib...

Available transfer capability (ATC) is the transfer capability remaining in the physical transmission network for further commercial activity over and above already committed uses which needs to be posted in the electricity market to facilitate competition. ATC evaluation is a complicated task including the determination of total transfer capability (TTC) and existing transfer capability (ETC)....

This paper presents fuzzy goal programming approach for bilevel linear fractional programming problem with a single decision maker at the upper level and a single decision maker at the lower level. Here, each level has single objective function, which are fractional in nature and the system constraints are linear functions. In the proposed approach, we first construct fractional membership func...

quality of products and services is considered as a key factor for customer satisfaction. quality function deployment (qfd) is known as a critical tool for translating voice of customers to prioritize technical requirements of a production. the level of this satisfaction depends on the number of fulfilled requirements. it should be noted that this level varies according to the possible constrai...

The outbreak of COVID-19 disrupted our everyday life. Many local authorities enforced a cordon sanitaire for the protection sensitive areas. Travellers can only pass after tested. This paper aims to propose method design an on-ramp control scheme maximise urban freeway network throughput with predetermined queuing delay constraint at all off-ramps around sanitaire. A bi-level programming model ...
