As each country shapes its offer, its critical task is to estimate the fixed cost to the firm of producing on its site, relative to the fixed cost to the firm of producing on the
A problem of structure optimization of a series}parallel production system is considered where redundant producing elements (machines) and in-process bu!ers are included in order
Then in order to enhance the solution of the Lagrangean heuristic, another procedure is developed to attain capacity feasibility in case of hierarchical relaxation before the
In the latter problem, an ideal solution (again not always feasible) is obtained by schedules which equalise the production load allocated to each parallel machine.. In fact, the

In this paper, assuming that we have vague data, the fuzzy bene " t } cost ( B / C ) ratio method is used to justify manufacturing technologies. After calculating the B / C
By carrying out a parametric analysis of the setup costs in the economic lot-sizing problem, we have obtained new results about the structure of optimal solution for given number
Comparison of the results from two methods: (i) modelling of nitrogen leaching; and (ii) N-balances for the root zones, showed that organic arable crop production and dairy /
