A Method for Determining Economically Optimal Loom Speed

An attempt has been made to develop a mathematical model to determine an economically optimal loom speed. The optimal loom speeds have theoretically been analyzed under the following three evaluating criteria; (1) the maximum production rate criterion to maximize the amount of fabrics woven in a unit time or the minimum time criterion to minimize the time necessary for weaving fabrics of unit area, (2) the minimum cost criterion relating to weaving a unit area of fabrics at the least cost, and (3) the maximum profit rate criterion to maximize the profit per unit time. The principle and algorism have been derived to determine the optimal loom speed by using the data obtained in practical weaving mills. Then, an example is shown to prove a simulation model successful.
