Hybrid flow shop scheduling as a multi-mode multi-project scheduling problem with batching requirements: A real-world application

Using Optimization Models for Scheduling in Enterprise Resource Planning Systems

“…Critical at the customer site is the tardiness of a customer order and the tardiness of a filter which will be assembled in other products should be as small as possible. Thus, minimizing total tardiness and analyzing average tardiness pT Mean q and standard deviation of tardiness pT σ q is in line with other studies; see Mouelhi-Chibani and Pierreval [5] or Rajendran and Alicke [6] for generated scheduling problems, as well as Voß and Witt [7] for a real-world application.…”

“…The general (single) scheduling problem consists of M stations and a pool of N jobs, which may change at any time, with known earliest possible starting times being, respectively, release dates Rajendran and Alicke [6] for generated scheduling problems, as well as Voß and Witt [7] for a realworld application.…”

Development of Scheduler Based on Simulation for Phone Camera Lens Module Manufacturing System

“…1에 제시된 바와 같이 경통-P1렌즈-스페이서1-P2렌즈-스페이 서2-P3렌즈-스페이서3-P4렌즈-쉴드 순으로 조립되어 하 나의 카메라 렌즈 모듈을 구성한다 [5,12] . 최근에는 고해상 도를 가진 렌즈 모듈이 요구되면서 일부 렌즈는 유리렌즈 를 사용하는 경우도 있지만 대부분의 렌즈는 플라스틱과 같은 열가소성 수지를 재료로 사출공정을 통해 생산된다.…”

“…일반적으로 스케줄링에서 사용하는 목적함수는 평균체 류시간 최소화, 평균지연시간 최소화, 납기지연작업수의 최소화 등이다 [10,11,12] . 또한 작업장의 특성도 단일 기계 스케줄링, 병렬 기계 스케줄링, 오븐과 같은 뱃치 스케줄 링 [5,10] 등과 같이 다양하다.…”

Study on disruption management scheduling problem of flow shop under supply chain environment

“…Many of them are proven NPhard problems [1] and the problem in this research is one of them. There are abundant researches about the global static scheduling and periodic rolling scheduling [2]. However, random disruption is more common in production and processing practical environment.…”
