In this study, 7738 cows with production, type, and productive life traits from 239 herds with information on milk, meat, food, housing, and labour costs were used. A lifetime net profit value was calculated for each cow. An average cow had the first calf at 28.6 months of age, 6149 kg of milk in the first lactation, a productive life of 1236 days, 3.28 lactations and a net profit of 410 euros ...

Abstract Some industrial data often come with uncertainty, which in some cases depends on the decision of those responsible for taking measurement production process.

A manufacturing inventory model with shortages with carrying cost, shortage cost, setup cost and demand quantity as imprecise numbers, instead of real numbers, namely interval number is considered here. First, a brief survey of the existing works on comparing and ranking any two interval numbers on the real line is presented. A common algorithm for the optimum production quantity (Economic lot-...
