Hybrid flow shop scheduling with prescription constraints on jobs
… This process can be modeled as a two-stage hybrid flow shop problem with specific constraints, particularly prescription constraints on the jobs. This thesis restates the practical problem as a scheduling problem by doing hypotheses and restrictions. Then, it designs a mathematical model …

Lot streaming in a two-stage assembly system and a hybrid flow shop
… 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, processing these sublots in an overlapping fashion over the …

Modeling, Analysis, and Algorithmic Development of Some Scheduling and Logistics Problems Arising in Biomass Supply Chain, Hybrid Flow Shops, and Assembly Job Shops
… three problems, Biomass Logistics Problem, Hybrid Flow Shop Scheduling Problem, and Stochastic Demand Assembly Job Scheduling Problem. The Biomass Logistics Problem is a strategic cost analysis for setup and operation of a biomass supply chain network that is aimed at the production of …

Planning for Army Force Generation Using Lot Streaming, and Extensions
… is made to each BCT, so as to minimize the total flow time. We propose a decomposition-based approach for the solution of this problem. In an effort to decompose the problem, the original lot streaming problem is reformulated such that the master problem selects an optimal combination of schedules …

Application of exact and approximate optimization methods to novel scheduling problems
… of workstations available in the production shop. In addition, each worker is characterized by a provided skill level, which affects the time required for completing setup operations. Firstly, a Mixed Integer Linear Programming (MILP) model suitable for tackling small instances of the problem …
