Inequalities for stochastic flow shops and job shops [PDF]

open access: possibleApplied Stochastic Models and Data Analysis, 1986
AbstractConsider an m‐machine flow shop with n jobs. The processing time of job j, j = 1,…, n, on each one of the m machines is equal to the random variable Xj and is distributed according to Fj. We show that, under certain conditions, more homogeneous distributions F1,…, Fn result in a smaller expected makespan.

Scheduling in Job Shops [PDF]

open access: possible, 1996
In this chapter we are going to consider scheduling tasks on dedicated processors or machines. We assume that tasks belong to a set of jobs, each of which is characterized by its own machine sequence. We will assume that any two consecutive tasks of the same job are to be processed on different machines. The type of factory layout is the job shop.

Scheduling the General Job-Shop

Management Science, 1985
A family of algorithms is described for finding optimum schedules for job-shops. The algorithms are of a branch and bound type but have a complete schedule associated with each node of the search tree. Branching from nodes is based on important conflicts in the schedule. Some results are provided.

On transforming job-shops into flow-shops

Production Planning & Control, 2002
In this paper the problem of transforming a job-shop environment into a flow-shop is addressed, where scheduling issues are simpler and pull production control systems might be easily applied. A linear programming model employing machine investment minimization as objective function is proposed.

Job-shop scheduling in a body shop

Journal of Scheduling, 2012
We study a generalized job-shop problem called the body shop scheduling problem (BSSP). This problem arises from the industrial application of welding in a car body production line, where possible collisions between industrial robots have to be taken into account.

Job Shop Scheduling

1997
The job shop scheduling problem (JSP) is a resource allocation problem where the resources are called machines. The problem involves finding an assignment (schedule) for a set of jobs to the machines so that the jobs can be completed “optimally.” Each job may consist of several tasks, and each task must be processed on a particular machine. Furthermore,
