A Framework and Measurement Instrument for Just-In-Time Manufacturing
Production and Operations Management, 2009
While Just-in-Time (JIT) manufacturing has emerged as one of the major tools to enhance manufacturing competitiveness, no attempt has been made to develop a reliable and valid measurement instrument for empirical research in JIT. Without such an instrument, generalization beyond the immediate sample is difficult or misleading. We have proposed a JIT framework and developed a valid and reliable instrument with 16 summated scales for dimensions that capture essential aspects of JIT useful in assessing its impact in manufacturing environments. In addition, we discuss in detail the interactive nature of JIT practice. And, we propose a step-by-step approach to reliability and validity testing. Four JIT practices (equipment layout, pull system support, supplier quality level, and Kanban) are identified as major contributing factors to JIT performance.
This paper presents the results of an empirical analysis on contribution of quality management (QM) and just-in-time (JIT) production practices to the efficiency and flexibility of manufacturing plants using survey data from 163 manufacturing plants in five countries. Twelve measurement scales were constructed to evaluate different aspects of QM and JIT production practices concerning with process, layout, supplier, training, and scheduling. Analysis of variance (ANOVA) technique and hierarchical regression were used to test the hypotheses. The results indicated that the high performance plants highly focus on both QM and JIT. In additional, joint implementation of QM and JIT production practices significantly produce a higher level of manufacturing performance when compared to the separate implementation of either one. The findings suggest the plants to explore the linkage and synergy of operational practices to achieve high competitive position in the global market.
A Comparative Study of Existing Manufacturing, Planning and Control Approaches
Mathematical and Computational Applications, 1996
During the 1980s various approaches to batch-type manufacturing environments were implemented. The most popular of these were Material Requirements Planning (MRP), ('JfOUP Technology (GT) and Just-In-Time (JIT). However few successful implementations of any of these approaches were achieved [1] [2] [3]. This paper compares the various approaches of GT, MRP, TIT along with the integrated approaches such as MRP/GT and MRPIllT. At present manufacturing industry suffers from economic recession and rapid changes of product design as well as from production planning and scheduling problems. The literature still lacks theories for making practical effective and flexible multi-product batch-type manufacturing systems [4] [5] [6]. Some effective approaches to the batch-type manufacturing systems have been developed: 1. Material Requirements Planning(MRP) which is used for manufacturing control in American industry. 2. Group Technology(GT) is a manufacturing philosophy which is widely used in British manufacturing. 3. The Japanese approach ofJust-In-Time(TIT) production. Recently some research has been carried out on integration of GTIllT and GTIMRP. Today, in an increasingly competitive manufacturing environment, higher levels of customer service (short and reliabledeliverytimes) are required, inventory costs have to be kept low and productivity has to be high. Market demands change quickly so that manufacturers can no longer operate in a steady state using long term fixed schedules. However existing systems are failingto provide the improvements required. They must move to a transient style similar to a TITIMRP type manufacturing system: keeping stocks at a minimum, low work-in-progress and shorter lead times as well as responding quicklyto changing demands.
A Study on The Challenges And Solutions To Just In Time Manufacturing
2017
The objective of this study is to understandthe existingchallengesin JIT including the challenge of eliminating or neutralizing Safety stock, Improper methods of production, Industry specific success factors of JIT, Reduced Setup time, Batch Production, Lot Size and Supply Chain Management.The relationship between Just in Time manufacturing (JIT) and Total Quality Management (TQM), a broader management philosophy has been observed.The Research methodology used in this paper includes the Case Study Approach and Game Simulation Analysis obtained from the literature reviews. The benefits and limitations of JIT vary across different industries, type and volume of production. Thus, they should be carefully studied before operating in the JIT manufacturing environment. It has been observed that TQM and JIT provided synergized benefits when implemented simultaneously. ---------------------------------------------------------------------------------------------------------------------------...
Recent trends in Manufacturing
The purpose of this paper is to present an interpretation of recent progress in manufacturing systems from the perspective of control. We believe that this community has a vocabulary and a view of systems that can be helpful in this area. However, in order for this group to make that impact, it is essential that they learn the problems and terminology and become familiar with recent research directions. This paper is intended to present certain issues in manufacturing management in a way that will facilitate in this direction by providing actions to be taken by the concerned enablers.
Competitive Control of the Manufacturing Systems
Competitiveness fully and synthetically characterizes the viability of an enterprise. In the economic literature competitiveness is analyzed in particular in economic and managerial terms with almost no insight into the analysis of the technology role in ensuring and developing competitiveness. Hence the need for manufacturing systems based on behavioural modelling and on line learning. The behavioural approaching is based on a continuous assessment of the situations and real-time decisions making. In this way it can be offered solutions to increase the competitiveness of the manufacturing systems. Based on theories about knowledge and complexity we can design an adaptable system to control the manufacturing systems, flexible reacting to the average solicitations. Behavioural management is characterized through the ability to perceive the environment, take the decision on time, in behind of interactions, with no specific procedures. Based on the above key ideas, in this paper, it is presented at a conceptual level a methodology for competitive control of the manufacturing systems.
Trending Towards Continual Improvements in Manufacturing Operations
International Journal Of Social Impact, 2021
In this ever-changing world, we perish if we do not change with changing times. In manufacturing also rapid changes are happening. Changing for better-"Improvement" is the keyword now. This paper deals with improvements in Manufacturing. We shall dwell on understanding the meaning of improvements-continuous/continual, shall learn the difference between these two terms and shall then demonstrate how continual improvements can be injected into major components of manufacturing operations. I hope the tips provided will go a long way to help entrepreneurs in improving the manufacturing operations of their business. Ready-made templates are also provided which would ease up their continual improvement efforts. I hope the paper serves its intended purpose of ushering in continual improvements in manufacturing sector, especially in entrepreneurially run traditional units.
