This paper presents a mathematical model for use in aquaculture, the rearing of aquatic animals in a controlled environment. The model addresses the real‐world strategic planning requirements of an emerging technology as well as the short‐ and long‐term production scheduling requirements of a mature aquaculture facility. A solution procedure for large‐scale problems is described and tested, and an illustrative application is presented.

ABSTRAmThe creation of new food sources is an important advancement in the search for solutions to food shortages in both developing and underdeveloped countries. Aquaculture. the production of aquatic animals under controlled conditions offers aciting n m possibilities for altemalive protein sources in a w d e variety of locales. This paper presents a mathematical programming model designed to aid the manager of an aquaculture facility in production scheduling and the evaluation of new technologies in this rapidly changing environment.

Techniques for representing system/process designs are a common feature of most design methodologies. These techniques can be enhanced to provide valuable information regarding a specific design structure's trade‐off between task completion times and cost. In this paper, we present a mathematical model and a solution algorithm which can be used to upgrade any well‐structured representation technique to provide this trade‐off. Having this information readily available allows a design team to focus on less quantifiable features of specific designs, thereby improving the overall design process.
