A Performance Evaluation of KANBAN, CONWIP and Base-stock in Serial Production Lines

چکیده
In managing a production process, choosing a proper card-based control mechanism is an important task to achieve the best performance. We present performance evaluation of the three well-known card-based production control mechanisms, KANBAN, CONWIP and Base-stock in serial production lines. We employ the theory of token transaction systems within a deterministic framework. The performance measures are system throughput and work-inprocess (WIP). We compare the minimum WIP, when the system attains maximum possible throughput. Our analytical results show that CONWIP outperforms KANBAN, when the total number of cards in CONWIP is less than that in KANBAN. However, in performance evaluation of these two mechanisms with Base-stock, determining the superior system depends on a configuration of system parameters, such as processing times and number of cards employed in the system.

Developing a unified framework for performance analysis of production control mechanisms
There exists controversy on the superiority of logistics control systems. In this paper, we propose a unified framework for analyzing and comparing of production control mechanisms. KANBAN, CONWIP and Base-stock control systems are focused on and analyzed as three well-known examples of production control systems. The periodic behavior of a token transaction system is used. By using the theory ...

One of the main efforts in a pull system to meet the final goal of Just-In-Time (JIT) is to decrease Work-In-Process (WIP) without reducing throughput rate and service level. This paper proposes a new hybrid control policy using Kanban, Base Stock and CONWIP to form the final construction of production plan, and then the function of new model is shown by a 3 stage case study with probabilistic ...
متن کاملEvaluation of multi-product lean manufacturing systems with setup and erratic demand
The consideration of demand variability in Multi-Product Lean Manufacturing Environment (MPLME) is an innovation in production system engineering. Manufacturing systems that fail to recognise demand variability generate high Work-In-Process (WIP) and low throughput in MPLME. In response to demand variability, organisations allocate large quantities of Production Authorisation Cards (PAC). A lar...
متن کاملReview on Just in Time Techniques in Manufacturing Systems
The control policy affects performance of a manufacturing line and can be classified as push, pull, or combination of pull and push. A pull or just-in-time (JIT) production system is a philosophy or an approach of the manufacturing system in which order release occurs due to physical removal of finished inventory in response to the customer demand. In this paper, we review the behavior of a man...
متن کاملThe optimal control of just-in-time-based production and distribution systems and performance comparisons with optimized pull systems
In just-in-time (JIT) production systems, there is both input stock in the form of parts and output stock in the form of product at each stage. These activities are controlled by production-ordering and withdrawal kanbans. This paper discusses a discrete-time optimal control problem in a multistage JIT-based production and distribution system with stochastic demand and capacity, developed to mi...
