The energy consumed around the world and especially in Morocco is dominated by oil products. The latter; whether in the global or the national context; are mainly due to diesel, whose climate impacts are well established, suggesting the search for a greener alternative. Despite its virtues, biodiesel is struggling to impose itself for purely economic reasons. Thus, in order to offer a sustainable solution, while keeping in mind the unpredictable fluctuations (price, demand …). This work proposes a generalization of fuzzy goal programming into fully fuzzy goal programming and a relative application, where the aim is to have a final product at a competitive price.

全世界，特别是摩洛哥的能源消费以石油产品为主。后者; 无论是在全球范围内还是在国家范围内；主要是由于柴油，其对气候的影响已经确定，这表明正在寻求更环保的替代品。尽管有其优点，生物柴油仍在纯粹出于经济原因而努力实施。因此，为了提供一种可持续的解决方案，同时牢记不可预测的波动（价格，需求……）。这项工作提出了将模糊目标程序设计推广到完全模糊目标程序设计及其相关应用中的目的，其目的是以具有竞争力的价格获得最终产品。
