Review of Doctoral Dissertation Autonomous University of Central America (UACA)

Abstract

This research work is related to the topic of tight systems and the search for new techniques for reducing cycle times. The work involves a review and documentary analysis of the views of international experts around the implementation of globally adjusted production systems. Likewise, the author reviews the traditional methods, as well as the most up-to-date methods in this area and raises his views.

The research culminates with the author's verification of the possibility of rethinking the heuristic sequencing rules proposed by two well-known authors: Gupta (1972) and Campell (1967), to introduce substantive improvements from the perspective of reducing execution times and queue times, thereby favoring the overall profitability of the value chain.

Particularly for Costa Rica, the author says that the implementation of tight systems is apparently carried out in an automated manner, where sequencing methods are not strongly used or consistently; what the author was able to demonstrate is that the algorithms of Gupta and Campell are used, aspects that precisely the author proposes in his work that must be rethought to adjust them and obtain substantial improvements in the processes, thus favoring the overall profitability of the value chain.
