Abstract

In this note we consider the NP-complete one-setup version of the two-machine flexible manufacturing cell scheduling problem studied by Lee and Mirchandani [5]. We provide a pseudopolynomial dynamic programming algorithm to solve the problem, thus establishing that the problem is NP-complete in the ordinary sense. We derive a tight worst-case error bound for the heuristic presented by Lee and Mirchandani, and propose another heuristic with a tight worst-case error bound of 3/2.
