Due to the adverse impact of seaborne sulfur emissions on coastal areas, Ministry Transport People’s Republic China is planning implement a 0.1% cap bunker fuel in domestic emission control area (DECA) 1 January 2025. As current DECA width only 12 NM, ships can bypass reduce use high-priced ultra-low oil (ULSFO) and thus save costs. The purpose this study first assess effect China’s 12-NM-wide ...

Abstract As a flexible unit that can respond quickly, CSP stations be included in the planned power source of supply planning, which effectively improve consumption volatile new energy and resource utilization. This paper mainly studies optimal planning grids containing fluctuating sources proposes joint based on bi-level programming model. The results calculation examples show proposed model c...

Bi-level programming techniques are developed to handle decentralized problems with two-level decision makers, leaders and followers, who may have more than one objective to achieve. This paper proposes a λ-cut and goal programming based algorithm to solve fuzzy linear multiple objective bi-level (FLMOB) decision problems. First, based on the definition of a distance measure between two fuzzy v...

An integrated optimization framework, including location assignment under grouping class-based storage policy and schedule of dual shuttle cranes, is offered by presenting a new optimization programming model. The objective functions, which are considered at this level, are the minimization of total costs and energy consumption. Scheduling of dual shuttle cranes among specified locations, which...

This paper proposes a kind of bi-level linear programming problem, in which there are two decision makers in a hierarchy and they have a common variable. To deal with this bi-level problem, we introduce a virtual decision maker, who controls the common variable to maximize the sum of the objective functions of the upper and lower level decision maker (the leader and follower). To illustrate the...

Some of the real life decisions are made in decentralized manner under uncertainty. Stochastic bi-level linear programming problems are used to handle such decision making problems. In this paper, we have proposed stochastic bi-level linear programming problems where some of the right hand side parameters of the constraints in both first (leader) and second level (follower) as normal and log-no...

The optimization of offshore wind farms is mainly performed through the deployment and submarine cables to maximize power output minimize cable costs. However, above results are affected by wake effect, equipment layout, cost cables. To effectively complete turbines lines, first, a bi-level constrained model based on maximum profit shortest route proposed in this paper; then, differential evolu...
