摘要:

Multistep decision processes with a vector-valued objective function are considered whereby the information about the step-dependent parameters is either complete or incomplete. In case of complete information the well-known necessary and sufficient functional equations can be extended with respect to the parameter dependence, but in case of incomplete information only the sufficiency of certain functional equations can be proved.

摘要:

New algorithms for enumerating all circuits of a directed graph are presented. These algorithms are backtrack algorithms, by which we intended to avoid fruitless computations. The best results give algorithms involving heuristic rules.

摘要:

The paper deals with the availability and the reliability analysis of a system with dependent units having a single repair facility subject to preventive maintenance. The system initially consists of n-identical units (connected in parallel) each with failure rate λn. The failure rate of a unit at any given instant of time depends upon the number of units operating at that instant. The time to repair of a failed unit and the time for maintenance of the repair- facility are arbitrarily distributed whereas the time to failure of a unit is exponentially distributed. The results obtained have been compared with those obtained when the repair facility is not subject to preventive maintenance.

摘要:

We consider a stochastic multicommodity periodic review inventory system with proportional costs plus a single set-u cost. The replenishment policy is of the (σS)-type (either nothing is ordered or all commodities are ordered simultaneously). For two classes of (σS)-policies and Erlang demand distributions of the order one and two we obtain approximations to optimal ordering parameters. Numerical examples are given.

We consider GI/GI/1/0-systems with input-dependend times (An arriving call may end the running service). The systems with independent interdeparture times are characterized.
