Planning for Army Force Generation Using Lot Streaming, and Extensions
… due windows. We formulate this problem as a lot streaming problem. Lot streaming splits a batch of jobs into sublots,which are then processed over the machines in an overlapping fashion. To schedule classes for the IMT, there are two stages that must be coordinated: Basic Training (BT) and …

Lot Streaming in Two-Stage Flow Shops and Assembly Systems
… work presented in this dissertation relates to lot streaming in two-stage flow shops and assembly shops. Lot streaming refers to the process of splitting a production lot into sublots, and then, processing the sublots on different machines simultaneously in an overlapping manner. Such a strategy …

Lot streaming and batch scheduling: splitting and grouping jobs to improve production efficiency
… in particular related to production efficiency. Lot streaming refers to the process of splitting jobs to move production through several stages as quickly as possible, whereas batch scheduling refers to the process of grouping jobs to improve the use of resources and customer satisfaction. We use …

Lot streaming in a two-stage assembly system and a hybrid flow shop
In this dissertation, we investigate the use of lot streaming in a two-stage assembly system and a two-stage hybrid flow shop in order to improve system performance. Lot streaming accelerates the flow of a production lot through a production process by splitting it into sublots, and then, …

Optimal and heuristic solutions for the single and multiple batch flow shop lot streaming problems with equal sublots
… in the flow-shop environments which utilize lot-streaming. Lot streaming is a commonly used process of splitting production lots into sublots and, then, of scheduling the sublots in an overlapping fashion on the machines, so as to expedite the progress of orders in production and to improve …

Optimal sublot determination in multiple batch stage, two stage production systems
… by splitting the batches to process into sub lots. The technique used to split batches into sub lots is the Lot Streaming method. In this thesis, the Lot Streaming problem is mathematically analyzed for the multiple batch/two-machine case under the criteria of minimizing the production cost …

Modeling, Analysis, and Algorithmic Development of Some Scheduling and Logistics Problems Arising in Biomass Supply Chain, Hybrid Flow Shops, and Assembly Job Shops
… Problem concerns with production scheduling of a lot over a two-stage hybrid flow shop configuration of machines, and is often encountered in `flexible manufacturing systems'. We incorporate the use of `lot-streaming' in order to minimize the makespan value. Although a general case of this problem …
