This paper proposes a penalty-shift-insertion (PSI)-based algorithm for the no-wait flow shop scheduling problem to minimize total flow time. In the first phase, a penalty-based heuristic, derived from Vogel’s approximation method used for the classic transportation problem is used to generate...

Lot streaming is the process of splitting a production lot into sublots, and then, scheduling the sublots in an overlapping fashion on the machines. In this paper, we present a polynomial-time procedure for determining the number of sublots of a single-lot, multiple-machine flow shop...

The random nature of soil loss under alternative land-use practices should be an important consideration of soil conservation planning and analysis under risk. Chance constrained programming models can provide information on the trade-offs among pre-determined tolerance levels of soil loss,...
