A simheuristic algorithm to set up starting times in the stochastic parallel flowshop problem

الگوریتم Simureistic برای تنظیم زمان شروع در مسئله جریان موازی تصادفی This paper addresses the parallel flowshop scheduling problem with stochastic processing times, where a product composed of several components has to be finished at a particular moment. These components are processed in independent parallel factories, and each factory can ...

Optimized rescheduling of multiple production lines for flowshop production of reinforced precast concrete components

مقالات مهندسی صنایع

بازبینی بهینه شده از خطوط تولید چندگانه برای تولید جریان از قطعات بتنی تقویت شده بتن Flowshop production is adopted as the major type of production of reinforced precast concrete components and it has higher requirements on shop floor schedules than other types, especially that from rescheduling. However, up to ...

On scheduling inclined jobs on multiple two-stage flowshops

flowshop

برنامه ریزی مشاغل در جریان کار دو مرحله ای We study scheduling on multiple two-stage flowshops in which each job has to pass through an R-operation and a T-operation. Motivated by the current research in data centers, we consider two restricted versions of the problem in which the jobs are ...

Solving the single crane scheduling problem at rail transshipment yards

flowshop

حل مسئله برنامه ریزی تک جرثقیل در جاده های حمل و نقل ریلی   We consider crane scheduling at rail transshipment yards, in which gantry cranes move containers between trains, trucks and a storage area. The single-crane scheduling problem arises at crane transshipment terminals and as a subproblem of the ...

Parallel tabu search for the cyclic jobshop scheduling problem

مقالات مهندسی صنایع

برنامه ریزی چرخه موازی با استفاده از الگوریتم تابو سرچ چکیده: In this paper, we consider a cyclic jobshop problem, consisting of production of a certain set of elements at fixed intervals. Optimization of the process is reduced to a minimization of a cycle time, i.e. the time, after which ...

minimizing total tardiness in a two-machine flowshop scheduling problem with availability constraint on the first machine

مقالات مهندسی صنایع

به حداقل رساندن خستگی کامل در یک مشکل زمانبندی جریان دو ماشین با محدودیت دسترسی در اولین ماشین چکیده: This paper deals with a two-machine flowshop problem in which the machine at the first stage requires preventive maintenance activities that have to be started within a given cumulative working time ...
