Flow shop scheduling example
WebFLOW SHOP SCHEDULING Given: A set of jobs each having some tasks to be performed. Processors for each of the tasks. Main Objective- To determine the order of assigning the tasks to processors such that the sum finishing time is minimal. EXAMPLE Two jobs have to be scheduled on three processors. The task times are given in the matrix below WebAn efficient MILP-based approach is presented to solve flow shop scheduling problems in automated manufacturing systems. The problem comprises complex production constraints and stringent storage policies in a multiple product multistage batch process. ...
