An alternative solution to the analytic hierarchy process

Maria Teresa Lamata
2006 International Journal of Intelligent Systems  
To obtain the scoring that corresponds to the best alternative, or the ranking of the alternatives, we need to use a total order for the graded numbers involved in the problem.  ...  In this article, we consider a definition of such a total order, which is based upon two subjective aspects: the degree of optimism/pessimism and the liking for risk /safety.  ...  Acknowledgments We are thankful to José Antonio Herencia for helpful comments and the anonymous referees for their valuable comments that improved the quality of this paper.  ...

Fuzzy job shop scheduling with lot-sizing

Sanja Petrovic, Carole Fayad, Dobrila Petrovic, Edmund Burke, Graham Kendall
2007 Annals of Operations Research  
This paper deals with a problem of determining lot-sizes of jobs in a real-world job shop-scheduling in the presence of uncertainty. The main issue discussed in this paper is lot-sizing of jobs.  ...  The objectives that are used to measure the quality of the generated schedules are average weighted tardiness of jobs, the number of tardy jobs, the total setup time, the total idle time of machines and  ...  The initial research on lot-sizing was related to the economic order quantity problem, where demand for a product is assumed to be stationary, i.e. an order for a product is continuously placed with a  ...
