题可能被修改。在JIT供应链管理相关的研究工作中,应该努力在启发式概率条件下得出开发仿真的结果。
关于单链分析多个连锁经营提出了一个悬而未决的问题,它是一个由单一制品水平为所有产品提供单位产品水平的问题(萨拉米娃蒂等[69])。此外,大多数研究利用电脑模拟。因此,为了研究的发展,今后的研究方向应是发展以及改善看板系统在制品搜索程序中的水平(克里格等[38])。一个分解算法可开发多种符合计算国家相关的设置看板系统的产品的方法。该合理方法是由他所提出的(塔蒂夫等[85])。该方法可适用于扩展到多产品多级看板系统。有人为了研究该算法的延伸性进行并实验,包括更多的变数和因素,如在需求和随机需求的突然增加情况下以及在各种条件下,对不同类型的客户系统使用生产模式的稳定性进行行为试验(励等[41])。嵌套分区方法是由他们提供的,可以精心划分纳入任何一个或其它的许多如抽样,回溯方案,仿真等增强启发式的组合(乐苑世与赵树理男士[43])。然后,他们可以应用这种方法解决这种类型的组合问题。
蚂蚁的蚁群优化算法是最近加入到现有的启发式,模拟退火算法,遗传算法和禁忌搜索中去的。因此,研究人员可以根据自己的兴趣和所需的计算时间针对JTI问题的组合分别采取不同的算法,研究其他三种启发式(启发式)的结果并比较结果的准确性。

Literature review of JIT-KANBAN system
Abstract In this paper, JIT (Just-In-Time) -KANBAN literature survey was carried out and presented.The introductory section deals with the philosophy of JIT,and the concept involved in the push and pull system. The blocking mechanisms in the kanban system are also discussed elaborately. Besides these sections, the importance of measure of performance (MOP) and the application of the same with respect to JIT-KANBAN are presented. The recent trends in the JIT-KANBAN are discussed under the heading “Special cases”. In this review, 100 state-of-art research papers have been surveyed. The directions for the future works are also presented.
1 Introduction
Just -In-Time (JIT) manufacturing system was developed by Taiichi Ohno which is called Japanese “Toyota production system”JIT manufacturing system has the primary goal of continuously reducing and ultimately eliminating all forms of wastes (Brown et al. [5],Ohno [54], Sugimori et al. [82]). Based on this principle,Japanese companies are operating with very low level of inventory and realizing exceptionally high level of quality and productivity (Richard J. Tersine [62], James H. Greene [30]). JIT emphasizes “zero concept” which means achievement of the goals of zero defects, zero queues,zero inventories, zero breakdown and so on. It ensures the supply of right parts in right quantity in the right place and at the right time. Hence, the old system of material acquisition and, buyer and seller relationships are changed to new revolutionary concepts (Womack et al. [91], Womack and Jones [92], Markey et al. [45]). Similarly, JIT becomes an inevitable system at plant level, which integrates the cellular manufacturing, flexible manufacturing, computer integrated manufacturing and Robotics (Schonberger [63], Golhar [12]).

Due to the technological advancement, the conventional method of push production system linked with Material Requirement Planning (MRP) was changed to pull type JIT production system to meet out the global competition, where the work-in-process (WIP) can be managed and controlled more accurately than the push- production system (Mason Paul [46]).
KANBAN system is a new philosophy, which plays a significant role in the JIT production system. Kanban is basically a plastic card containing all the information required for production assembly of a product at each stage and details of its path of completion. The kanban system is a multistage production scheduling and inventory control ystem. These cards are used to control production flow sand inventory. This system facilitates high production volume and high capacity utilization with reduced production time and work-in-process.
The objectives of this paper are as listed below 1) Critical review of JIT literature.
2) Segregating the different research articles of JIT.
3) Exploring the recent trends in JIT-Kanban system and deriving directions for future research.
In this paper, the articles are reviewed and an appropriate classification is presented.The kanban study was made elaborately, since it acts as a basic communicator and feedback agent to the JIT system. Push and pull system, principle of operation of kanban cards, Blocking mechanism, Toyota’s formula, and the measures of performances (MOP) are also discussed in this paper. The latest trends in JIT-Kanban system are also addressed separately under the heading “Special cases”. Finally, the directions for future researches are presented.

1.1 Flow shop
Kanban system is widely implemented in repetitive manufacturing environment. For a single card operational system, Sharadhapriyadarishini et al. [77] have developed two heuristics and proved that these are more efficient. Saradhapriyadarishini et al. [78] have proposed a recursive equation for scheduling the single card kanban system with dual blocking. They proposed a heuristic with twin objectives of minimizing the sum of total weighted time of containers and weighted flow time of part-types. Rajendran [61] has done a work on two card flow shop scheduling with n part-types. In this paper, mathematical models for time tabling of containers for different problems have been formulated. Then, a heuristic was developed to minimize the sumof weighted flow time, weighted earliness, and weighted tardiness of containers. Hemamalini et al. [22] have done similar work. In this work, the heuristic developed is simulated annealing algorithm. This is compared with randomsearchmethod. In these papers, the comparisons are done only based on mean relative percentage increase. Instead of this approach, comparisons based on complete ANOVA experiments would provide reliable inference.
Peter Brucker et al. [58] have carried out research on flow shop problem with a buffer of limited capacity between two adjacent machines. After finishing the processing of a job on a machine, either the job is to be processed on the following machine or it is to be stored in the buffer between these machines. If the buffer is completely occupied, the job has to wait on its current machine but blocks this machine for other jobs. In this paper, they determined a feasible schedule to minimize the makespan using tabu search. The results of the problem using tabu search were compared with that of benchmark instances. The comparisons are done only based on relative improvements. Instead of this approach, comparisons based on complete ANOVA experiments would provide reliable inference.
