This research is dedicated to the Production Scheduling Problem in a hybrid flow shop with setup times separated from processing times. The goal is to identify and analyze the current literature to identify papers that develop methods to solve this problem. In this review, it was possible to identify and analyze 72 papers that have addressed this issue since 1991. Analyses were performed using the number of papers published over the years, the approach used in the development of the methods for the solutions, the type of objective function, the performance criterion adopted, and the additional constraints considered. The analysis results provide some conclusions about the state of the art in the subject and also enable us to identify suggestions for future research in this area. [ABSTRACT FROM AUTHOR]

This paper aims to present a proposal of a hybrid MRPII (Manufacturing Resources Planning) - CPM (Critical Path Method) production planning and control system (PPCS). The proposal was implemented in a big Brazilian industry which manufactures heavy equipment. The results showed that that the average value of WIP was reduced in about 31.4%, the average lead time was reduced in about 38.9% and the average delay of the final products was reduced in about 60.9%. Besides the results regarding reduction on average WIP, lead time and delay, the paper presented a practical example of the possible integration between a PCP hybrid system (MRPII and CPM) and a production-scheduling tool (DAA approach), showing that the information systems integration is an important tool to achieve a satisfactory performance of production planning, scheduling, and control [ABSTRACT FROM AUTHOR]
