Production and distribution operations are the two most important operational functions in a supply chain. To achieve optimal operational performance in a supply chain, it is critical to integrate these two functions and plan and schedule them jointly in a coordinated way. In this chapter, we focus on integrated models that involve explicitly both production and distribution decisions at the ta...

In this paper we explore the functional correlation approach to operational risk. We consider networks with heterogeneous a priori conditional and unconditional failure probability. In the limit of sparse connectivity, self-consistent expressions for the dynamical evolution of order parameters are obtained. Under equilibrium conditions, expressions for the stationary states are also obtained. C...

The role and contribution of satellite data in operational oceanography is reviewed, with emphasis on northern European seas. The possibility to observe various ocean parameters and processes by existing satellite sensors, such as optical instruments, infrared radiometers, passive Ž . microwave radiometers, and active microwave systems altimeter, scatterometer, SAR is discussed. The basic param...

the effects and influences of various parameters upon the efficiency and the overall volumetric mass transfer coefficients are important subjects to be studied in most liquid-liquid extraction processes. one of these important parameters is surface active agent (surfactant). in this paper, in order to study the effect of sodium dodecyl sulfate (sds) concentration on the efficiency and the avera...

the performance of a forced-liquid vertical tubular loop bioreactor (vtlb), a forced-liquid horizontal tubular loop bioreactor (htlb) and a gas-induced external airlift loop bioreactor (ealb) were compared for production of biomass from natural gas. hydrodynamic characteristics and mass transfer coefficients were determined as functions of design parameters, physical properties of gases as well...
