Machines can have duplicates (flexible job shop with duplicate machines) or belong to groups of identical machines (flexible job shop). [3] Machines can require a certain gap between jobs or no idle-time. Machines can have sequence-dependent setups. Objective function can be to minimize the makespan, the L p norm, tardiness, maximum lateness ...
Flow Shop Ordonnancement. Flow-shop scheduling is an optimization problem in computer science and operations research.It is a variant of optimal job scheduling.In a general job-scheduling problem, we are given n jobs J 1, J 2, ..., J n of varying processing times, which need to be scheduled on m machines with varying processing power, while trying to minimize the makespan – the total length ...
The Shifting Bottleneck Heuristic is a procedure intended to minimize the time it takes to do work, or specifically, the makespan in a job shop.The makespan is defined as the amount of time, from start to finish, to complete a set of multi-machine jobs where machine order is pre-set for each job.
A job shop is a manufacturing system that handles custom/bespoke or semi-custom/bespoke manufacturing processes, such as small to medium-size customer orders or batch jobs. Such a process is called "job production." Job shops typically move on to different jobs (possibly with different customers) when each job is completed.
The Flex app is where drivers find package delivery jobs in their area. After they log in, drivers will repeatedly tap a big orange refresh button until delivery shifts, referred to as "blocks ...

Optimal job scheduling is a class of optimization problems related to scheduling. The inputs to such problems are a list of jobs (also called processes or tasks) and a list of machines (also called processors or workers). The required output is a schedule – an assignment of jobs to machines. The schedule should optimize a certain objective ...
