Some of the problems that concern the proper methods for consideration of several different objectives in reservoir planning are discussed. Classical systems analysis approach to decision making for multiple objective problems is outlined and the inherent difficulties associated with multiple objectives and subjective estimates are identified. Techniques used in reservoir design and operation are reviewed. An alternate technique for considering noncommensurate, objectives, which relates the objectives in terms of real trade-off costs and eliminates the need for a priori estimates of objective worth is presented. The method is illustrated with three examples, including a reservoir operation problem and a cooling tower design problem. 31 refs, cited.

Fentanyl transdermal delivery systems (FTDS) use an unsealed multilaminate system containing a solid matrix, in which fentanyl is embedded instead of the reservoir designed in the TTS. FTDS is not to be recommended for routine postoperative pain treatment, even though it has a faster onset of action (4—6 hours) after cases of fentanyl toxicity, especially respiratory depression. FTDS has not been investigated adequately in chronic pain and is not expected to be superior to the TTS technique.

The most important physical characteristic of a reservoir is its storage capacity. Probably the most important aspect of storage in reservoir design is the relationship between capacity and yield. The yield is the quantity of water that a reservoir can supply at any given time. The maximum possible yield equals the mean inflow less evaporation and seepage loss. In any consideration of yield, the maximum quantity of water that can be supplied during a critical dry period (i.e. during the lowest natural flow on record) is of prime importance and is defined as the safe yield.
