This paper presents a mathematical model for a flow shop scheduling problem consisting of m machine and n jobs with fuzzy processing times that can be estimated as independent stochastic or fuzzy numbers. In the traditional flow shop scheduling problem, the typical objective is to minimize the makespan). However,, two significant criteria for each schedule in stochastic models are: expectable m...

correct estimation of suspended sediment transported by a river is an important practice in water structure design, environmental problems and water quality issues. conventionally, sediment rating curve used for suspended sediment estimation in rivers. in this method discharge and sediment discharge or concentration related using regression relation that generally is exponential model. respect ...

Deontic logic is a branch of symbolic interested in notions such as obligatory, permissible, optional, ought, and others similar. There are some equivalent ways to present the Standard Logic or KD. In this paper, we will mention them highlight one that interest. With presentation can propose simple algebraic model for Logic.
