• Analytical chemists are faced with the problem of choosing an appropriate analytical technique for a particular sample and weighing the options as they affect precision, time, and cost. This paper describes a computer technique to assist managers in reviewing the alternatives and to match needs with the resources available. This paper proposes an expert system, knowledgeable of analytical chemistry techniques, to create sample plans. Sample planning is an appropriate topic for expert systems because scarce human expertise is required to complete sample plans. A sample plan is the description of how samples received at the Savannah River Laboratory are handled, controlled, measured, and dispositioned. Sample planning is difficult because multiple experts are needed, planning is not a static function, and planning is time consuming. An Expert Sample Analyses Planner (XSAP) is proposed to create sample plans for laboratory managers. XSAP supplements the scarce knowledge of analytical techniques creating sample plans based on analysis constraints, methods available, and time requirements. XSAP interacts with the chemist to suggest sample plans. XSAP considers equipment available locally, at other Savannah River laboratories, at other Department of Energy facilities, and at other commercial laboratories. XSAP allows options on scheduling: best solution, cheapest solution, best localmore?? solution, and fastest solution. 26 refs.??less ()
