| Abstract Shrimp farming has a great ecological, economic, and social importance in northeastern Brazil. Although the conventional farming system is widely used, biofloc technology (BFT) system has been developed to reduce environmental impacts and optimizing the production. Thus,the present study evaluated the technical efficiency of production cycles of Litopenaeus vannamei in conventional and BFT systems.We analyzed 48 production cycles in the conventional system in 2013 and 2014 and 9 cycles in the BFT system in 2014 through data envelopment analysis (DEA). The inputs corresponded to the population density (post-larvae m-2), amount of feed (kg ha-1 cycle-1), labor (man ha-1) and power supply (HP ha-1), whereas the yield (kg ha-1 cycle-1) was considered... |

| Considering that the concepts of dynamic production system and traditional system are placed in opposite sides of a continuum, the critical factor for the companies is in finding the break-even point desired to maximize the results and to reduce costs. The aim of this paper is to verify the situation of the manufacturing company when using characteristics of both flexible production system and static system to keep a good level of service and to reduce operational costs. The qualitative research was based on a case study of a great nourishing branch company. The results shows that the company is located inside of continuum considered, thus getting a satisfactory balance between the corresponding level of service to the customer and operational costs. It... |
