Reliability Evaluation of Stochastic-flow Network through Two Minimal Intersecting Paths under Budget and Time Constraints
A stochastic flow network (SFN) is more suitable than a general network to describe some real systems as it is composed of multistate links as well as multistate nodes. As the nodes and the links have different capacities at different time, the minimum transmission time through a stochastic flow network is not fixed. In order to shorten the transmission time, in this paper the data are allowed ...
متن کاملThree Hybrid Metaheuristic Algorithms for Stochastic Flexible Flow Shop Scheduling Problem with Preventive Maintenance and Budget Constraint
Stochastic flexible flow shop scheduling problem (SFFSSP) is one the main focus of researchers due to the complexity arises from inherent uncertainties and also the difficulty of solving such NP-hard problems. Conventionally, in such problems each machine’s job process time may encounter uncertainty due to their relevant random behaviour. In order to examine such problems more realistically, fi...
متن کاملMinimizing Average Flow-Time under Knapsack Constraint
We give the first logarithmic approximation for minimizing average flow-time of jobs in the subset parallel machine setting (also called the restricted assignment setting) under a single knapsack constraint. In a knapsack constraint setting, each job has a profit, and the set of jobs which get scheduled must have a total profit of at least a quantity Π. Our result extends the work of Gupta, Kri...
متن کاملLeast Expected Time Paths in Stochastic, Time-Varying Transportation Networks
We consider stochastic, time-varying transportation networks, where the arc weights (arc travel times) are random variables with probability distribution functions that vary with time. Efficient procedures are widely available for determining least time paths in deterministic networks. In stochastic but time-invariant networks, least expected time paths can be determined by setting each random ...
متن کاملFuzzy completion time for alternative stochastic networks
In this paper a network comprising alternative branching nodes with probabilistic outcomes is considered. In other words, network nodes are probabilistic with exclusive-or receiver and exclusive-or emitter. First, an analytical approach is proposed to simplify the structure of network. Then, it is assumed that the duration of activities is positive trapezoidal fuzzy number (TFN). This paper com...
