In this paper, the expression “production systems” refers to flow shops, job shops, assembly systems, Kanban systems, and, in general, to any discrete event system which transforms raw material and/or components into products and/or components. Such a system is said to be cyclic if it provides the same sequence of products indefinitely. A schedule of a cyclic production system is defined as soo...

Physical factory layout redesigns or changes of the supply chain infrastructure involve high costs. Through simulation and value stream mapping, managers can see the impacts before the implementation and transform the organization into a lean one at minimal cost. In this paper, we investigate some relevant lean manufacturing literature where lean principles and tools are presented or utilized. ...

Heijunka is a key-element of the Toyota production system. It is used to level the release of production kanbans in order to achieve an even production program over all possible types of products thus reducing or eliminating the bullwhip effect. In this paper the dependencies between the parameters of the levelling process and the requirements in finished goods stocks are derived, resulting in ...

This paper presents an introductory overview and tutorial in simulation modeling and control of serial Kanban and CONWIP (CONstant Work In Process) pull systems using ARENA/SIMAN 3.5/4.0. Card level estimation is discussed for both types of pull systems, and a heuristic method to adjust card levels controlling system WIP (Work In Process) is provided. The objective is to present a tutorial for ...

We consider a two-stage production-inventory system with demand at the downstream stage and returns at each stage. We characterize the structure of the optimal policy which is a complex state-dependent Base-stock policy. We also investigate four classes of policies : Fixed buffer, Base-stock echelon, Kanban and Half-optimal. We compare the performances of these policies and exhibit that the max...

Pada saat ini untuk meningkatkan keefektifan dan keefesienan perusahaan dibutuhkan suatu pendekatan keilmuan yang sudah teruji. Konsep kanban dipublikasikan cukup lama membuktikan bahwa dengan menerapkannya akan efesiensi. Penelitian dilakukan meningkatan konsep cara digitalisasi. Studi kasus di menerapkan sistem Kanban terintegrasi Sistem ERP-nya berupa Ms Dynamics AX.Penelitian dimulai wawanc...
