In this paper, during the programming process of a "Job Shop" manufacturing system, some expectations of the following stakeholders, are integrated: suppliers, society, employees of the organization, clients and shareholders. In this way, a multiobjective evaluation process is designed. This process lets to minimize, the set of variables presented below: makespan time, carbon dioxide emissions, fatigue level, waste global factor and production costs. Likewise, it is expressed that the proposed method is based on the selection of those chromosomes, whose degree of proximity to certain reference points, is the maximum possible. In this respect, the performance of the previous method (method: reference points), is compared with the performance of a certain multiobjective method, based on subgroup analysis (method: subgroups). Thus, it is observed that the first method shows, greater capacity to detect the statistical fluctuation inherent to the data. In this way, it is established that the "method: reference points" exceeds the performance of the "method: subgroups", in terms of the behavior of the parameters "coefficient of variation" and "rank", in the case of 4 (makespan time, carbon dioxide emissions, fatigue level, production costs) of the 5 variables analyzed.

Keywords : multiobjective methods; production costs; fatigue level; stakeholders; Job Shop.
